TEActivate

Activates the specified edit structure. (Deprecated in OS X v10.4. Use Multilingual Text Engine instead; see Handling Unicode Text Editing With MLTE.)

void TEActivate (
   TEHandle hTE
);
Parameters
hTE

A handle to the specified edit structure.

Discussion

When your application receives notification of an activate event, it can call the TEActivate function, which activates an edit structure and highlights the selection range. If the selection range is an insertion point, TEActivate simply displays a caret there. Call this function every time the Event Manager function WaitNextEvent reports that the window containing the edit structure has become active.

If you do not call TEActivate before you call TEClick, TEIdle, or TESetSelect, the selection range is not highlighted, or, if the selection range is set to an insertion point, a caret is not displayed at the insertion point. However, if you have turned on outline highlighting through the TEFeatureFlag function for the edit structure, the text of the selection range is framed or a dimmed or an unblinking caret is displayed at the insertion point.

TEAutoView

Enables and disables automatic scrolling of the text in the specified edit structure. (Deprecated in OS X v10.4. Use Multilingual Text Engine instead; see Handling Unicode Text Editing With MLTE.)

void TEAutoView (
   Boolean fAuto,
   TEHandle hTE
);
Parameters
fAuto

A flag indicating whether to enable or disable automatic scrolling. A value of TRUE enables automatic scrolling; a value of FALSE disables automatic scrolling.

hTE

A handle to the edit structure for which automatic scrolling is to be enabled or disabled.

Discussion

The TEAutoView function does not actually scroll the text automatically: TESelView does. However, when fAuto is set to FALSE , a call to TESelView has no effect.

If there is a scroll bar associated with the edit structure, your application must manage scrolling of it. You can replace the default click loop function, which scrolls the text only, with a customized version that also updates the scroll bar.

You can also enable or disable automatic scrolling for an edit structure through the teFAutoScroll feature of the TEFeatureFlag function. For more information, see TEFeatureFlag.

TECalText

Recalculates the beginnings of all lines of text in the specified edit structure. (Deprecated in OS X v10.4. Use Multilingual Text Engine instead; see Handling Unicode Text Editing With MLTE.)

void TECalText (
   TEHandle hTE
);
Parameters
hTE

A handle to the edit structure whose text lines are to be recalculated.

Discussion

The TECalText function updates elements of the lineStarts array in an edit structure. Call TECalText if you’ve changed the destination rectangle, the hText field, or any other property of the edit structure that pertains to line breaks and the number of characters per line—for example, font, size, style, and so on.

void TEClick (
   Point pt,
   Boolean fExtend,
   TEHandle h
);
Parameters
pt

The mouse location in local coordinates at the time the mouse button was pressed, obtainable from the event structure (in global coordinates).

fExtend

A flag denoting the state of the Shift key at the time of the click as indicated by the Event Manager. If the Shift key was held down at the time of the click to extend the selection, pass a value of TRUE.

h

A handle to the edit structure whose text is displayed in the view rectangle where the click occurred.

Call TEClick whenever a mouse-down event occurs in the view rectangle of the edit structure and the window associated with that edit structure is active. The TEClick function keeps control until the mouse button is released. Use the QuickDraw function GlobalToLocal to convert the global coordinates of the mouse location given in the event structure to the local coordinate system for pt.

The TEClick function removes highlighting of the old selection range unless the selection range is being extended. If the mouse moves, meaning that a drag is occurring, TEClick expands or shortens the selection range accordingly a character at a time. In the case of a double-click, the word where the cursor is positioned becomes the selection range.

TEContinuousStyle

Determines whether a given character attribute is continuous over the current selection range. (Deprecated in OS X v10.4. Use Multilingual Text Engine instead; see Handling Unicode Text Editing With MLTE.)

Boolean TEContinuousStyle (
   short *mode,
   TextStyle *aStyle,
   TEHandle hTE
);
Parameters
mode

On input, a pointer to a selector specifying the attributes to be checked. On output, mode identifies only those attributes determined to be continuous over the selection range. Possible values for the mode parameter are defined in “Text Styling Constants.”

aStyle

On input, a pointer to a text style structure. On output, this structure contains the values for the mode attributes determined to be continuous over the selection.

hTE

A handle to the edit structure containing the selected text whose attributes are to be checked. If the value of hTE is a handle to a monostyled edit structure, TEContinuousStyle returns the set of character attributes that are consistent for the entire structure.

Return Value

TRUE if all of the attributes to be checked are continuous; FALSE if none or some are continuous. See the Mac Types documentation for a description of the Boolean data type.

Discussion

This function does not modify the text selection. If the current selection range is an insertion point, TEContinuousStyle first checks the null scrap. If the null scrap contains character attributes, then they are used based on the value of the mode parameter. Otherwise, if the null scrap is empty, TEContinuousStyle returns the attributes of the character preceding the insertion point. The TEContinuousStyle function always returns TRUE in this case, and each field of the text style structure is set if the corresponding bit in the mode parameter is set.

Note that fields in the text style structure specified by aStyle are only valid if the corresponding bits are set in the mode variable.

How the tsFace field of the aStyle structure is used requires some consideration. For example, if TEContinuousStyle returns a mode parameter that contains doFace and the text style structure tsFace field is bold, it means that the selected text is all bold, but may contain other text styles, such as italic, as well. Italic does not apply to all of the selected text, or it would have been included in the tsFace field. If the tsFace field is an empty set, then all of the selected text is plain.

TECopy

Copies the text selection range from the edit structure, leaving the selection range intact. (Deprecated in OS X v10.4. Use Multilingual Text Engine instead; see Handling Unicode Text Editing With MLTE.)

void TECopy (
   TEHandle hTE
);
Parameters
hTE

A handle to the edit structure containing the text to be copied.

Discussion

The TECopy function copies the text to the private scrap. For text of a monostyled edit structure, the text is written to the private scrap only. For text of a multistyled edit structure, the text is written to the TextEdit private scrap, the character attribute information is written to the TextEdit style scrap, and both are written to the Scrap Manager’s desk scrap. Anything previously in the private scrap is deleted before the copied text is written to it.

For both multistyled and monostyled text, if the selection range is an insertion point, TECopy empties the TextEdit private scrap. When the selection range is an insertion point and the text is multistyled, TECopy has no effect on the null scrap, the style scrap, or the Scrap Manager’s desk scrap.

TECustomHook

Replaces a default TextEdit hook function with a customized function and returns the address of the replaced function. (Deprecated in OS X v10.4. Use Multilingual Text Engine instead; see Handling Unicode Text Editing With MLTE.)

void TECustomHook (
   TEIntHook which,
   UniversalProcPtr *addr,
   TEHandle hTE

Parameters
which

The hook whose default function is to be replaced.

addr

On input, the address of your customized function.

On output, the addr parameter contains the address of the function that was previously installed in the field identified by the which parameter. This address is returned so that you can daisy-chain functions.

hTE

A handle to the edit structure to be modified.

Discussion

The TECustomHook function lets you alter the behavior of TextEdit to better suit your application’s requirements and those of the script systems installed. If you replace a default hook function with a customized version that you write in a high-level language, such as Pascal or C, you need to provide assembly-language glue code that utilizes the registers for your high-level language function.

The end-of-line hook, width measurement hook, new width measurement hook, text width measurement hook, draw hook, and hit test hook fields are hook fields in the TextEdit dispatch structure. The which parameter identifies the hook whose default function is to be replaced. You use the constants described in “Text Custom Hook Constants” to specify a value for this parameter.

Certain precautions are critical in replacing default functions. Before placing the address of your function in the TextEdit dispatch structure, strip the addresses, using the Operating System Utilities StripAddress function, to guarantee that your application is 32-bit clean.

Before replacing a TextEdit function with a customized one, determine whether more than one script system is installed, and if so, ensure that your customized function accommodates all of the installed script systems. This avoids the problem of your customized function producing results that are incompatible with the Script Manager.

Parameters
hTE

A handle to the edit structure containing the text to be cut.

Discussion

For monostyled text, the TECut function writes the cut text to the private scrap.

For multistyled text, TECut writes the cut text to the private scrap and its character attributes to the style scrap it also writes both to the Scrap Manager’s desk scrap. For multistyled text, the TECut function removes the character attributes from the style structure’s style table when the text is cut.

For both monostyled and multistyled text, if the selection range is an insertion point, TextEdit deletes everything from the private scrap. When the selection range is an insertion point and the text is multistyled, TECut has no effect on the style scrap or the Scrap Manager’s desk scrap.

Parameters
hTE

A handle to the specified edit structure.

Discussion

When the activate event flag is set to deactivate the window, your application can call the TEDeactivate function, which changes an edit structure’s status from active to inactive and removes the selection range highlighting or the caret.

However, if you turned on outline highlighting through the TEFeatureFlag function for the edit structure, the text of the selection range is framed or a dimmed or an unblinking caret is displayed at the insertion point when the structure is deactivated.

Call this function every time the Event Manager function WaitNextEvent reports that the window containing the edit structure has become inactive.

Parameters
hTE

A handle to the edit structure containing the text to be deleted.

Discussion

When the TEDelete function deletes a selected range of text, it does not transfer the text to either the private scrap or the Scrap Manager’s desk scrap.

For multistyled structures, when you use TEDelete to delete a selected range of text, the associated character attributes are saved in the null scrap to be applied to characters entered after the text is deleted. When the user clicks in some other area of the text, the character attributes are removed from the null scrap. You can use TEDelete to implement the Clear command. The TEDelete function recalculates line starts and line heights.

void TEDispose (

);
Parameters
hTE

A handle to the edit structure for which the allocated memory should be released.

Discussion

Call the TEDispose function only when you’re completely through with an edit structure.

Note that if your program retains a handle to text associated with the edit structure that you are destroying with TEDispose , the handle becomes invalid because the TEDispose function disposes of it, as well as the dispatch structure handle. If the structure is multistyled, TEDispose also disposes all of the style-related handles: STHandle, LHHandle, STScrpHandle, nullSTHandle, and TEStyleHandle.

To continue to refer to the text after you’ve destroyed the edit structure, you need to make a copy of the handle in the hText field of the edit structure using the Operating System Utilities HandToHand function before you call TEDispose.

In addition to disposing of the edit structure, the edit structure handle, and the dispatch structure handle, the TEDispose function destroys the null scrap associated with the edit structure and releases the memory used for it.

Parameters
offset

Return Value

The coordinates of the point that corresponds to the specified byte offset. The TEGetPoint function returns a valid result even when the edit structure does not contain any text. The point returned is based on the values in the structure’s destination rectangle.

In the case of an offset being equal to a line end, which is also the start of the next line, TEGetPoint returns a point corresponding to the line start of the next line. In the case of a dual caret, the primary caret position, the one corresponding to the primary line direction, is returned.

See the Mac Types documentation for a description of the Point data type.

Parameters
hTE

A handle to the edit structure.

Discussion

You need to call TEIdle only when the window containing the text is active; the caret is blinked only then. TextEdit observes a minimum blink interval, initially set to 32 ticks. No matter how often you call TEIdle, the time between blinks is never less than the minimum interval. (The user can adjust the minimum interval setting with the General Controls control panel.)

To maintain a constant frequency of blinking, you need to call TEIdle at least once each time through your main event loop. Call it more than once if your application does an unusually large amount of processing each time through the loop.

Call the Event Manager’s GetCaretTime function to get the blink rate.

void TEKey (
   CharParameter key,
   TEHandle hTE
);
Parameters
key

The input character.

hTE

A handle to the edit structure in whose text the character is to be entered.

Discussion

The TextEdit function TEKey allows you to handle key-down events and enter text input through the keyboard. If the selection range is an insertion point, TEKey inserts the character. (Two-byte characters are passed one byte at a time.)

If the key parameter contains a backspace character, the selection range or the character immediately before the insertion point is deleted. When the primary line direction is right-to-left, the character to the right of the insertion point is deleted. When the primary line direction is left-to-right, the character to the left of the insertion point is deleted.

When the user deletes text up to the beginning of a set of character attributes, TEKey saves the attributes in the null scrap’s style scrap structure. The attributes are saved temporarily to be applied to characters inserted after the deletion. As soon as the user clicks in another area of the text, TEKey removes the attributes. TEKey redraws the text as necessary.

Call TEKey every time the Event Manager function WaitNextEvent reports a keyboard event that your application determines should be handled by TextEdit.

Because TEKey inserts every character passed in the key parameter, your application must filter all characters which aren’t actual text, such as keys typed in conjunction with the Command key.

Parameters
destRect

A pointer to the destination rectangle for the new edit structure, specified in the local coordinates of the current graphics port. This is the area in which text is laid out.

viewRect

A pointer to the view, or visible, rectangle for the new edit structure, specified in the local coordinates of the current graphics port. This is the area of the window in which text is actually displayed.

Return Value

A handle to the newly created edit structure. Your application needs to store the handle to the edit structure that is returned; many functions require it as an input parameter. See the description of the TEHandle data type.

Discussion

A monostyled edit structure is one in which all text is restricted to a single font, size, and style. Use the TENew function when the text is to be rendered in attributes that are consistent from character to character. Otherwise, use the TEStyleNew function.

Call TENew once for every edit structure you want allocated. Your application should store the handle to the edit structure that is returned; many functions require it as an input parameter. The edit structure assumes the drawing environment of the graphics port.

If your application contains more than one window where text editing occurs, you need to create an edit structure for each window.

Before this function is called, the window must be in the current graphics port.

The number of character attribute changes contained in the specified range. This does not necessarily represent the number of unique sets of attributes for the range, because some sets of attributes may be repeated. For monostyled edit structures, TENumStyles always returns 1.

TEPaste

Replaces the edit structure’s selected text with the contents of the private scrap and leaves an insertion point after the inserted text. If the selection range is an insertion point, TEPaste inserts the contents of the private scrap there. (Deprecated in OS X v10.4. Use Multilingual Text Engine instead; see Handling Unicode Text Editing With MLTE.)

void TEPaste (
   TEHandle hTE
);
Parameters
hTE

A handle to the edit structure into which the text is to be pasted.

Discussion

When you call TEPaste, after it pastes the text from the private scrap, it redraws all of the text as necessary. If the private scrap is empty, TEPaste deletes the selection range. If you call TEPaste for a multistyled edit structure, it pastes only the text in the private scrap. In this case, TEPaste ignores any associated character attribute information stored in the style scrap; instead, it applies the character attributes of the first character of the selection range being replaced to the text. If the selection range is an insertion point, TEPaste applies the character attributes of the character preceding the insertion point.

TEPinScroll

Scrolls the text within the view rectangle of the specified edit structure by the designated number of pixels. Scrolling stops when the last line of text is scrolled into view. (Deprecated in OS X v10.4. Use Multilingual Text Engine instead; see Handling Unicode Text Editing With MLTE.)

void TEPinScroll (

);
Parameters
dh

The distance in pixels that the text is to be scrolled horizontally. A positive value moves the text to the right; a negative value moves the text to the left.

dv

The distance in pixels that the text is to be scrolled vertically. A positive value moves the text down; a negative value moves the text up.

hTE

A handle to the edit structure whose text is to be scrolled.

Discussion

The TEPinScroll function updates the text on the screen automatically to reflect the new scroll position, as does the TEScroll function. The destination rectangle is offset by the amount scrolled. When the edit structure is longer than the text it contains, TEPinScroll displays up to the last line of text inclusive, and not beyond it.

TEReplaceStyle

Replaces any character attributes in the current selection range that match the specified existing character attributes with the specified new character attributes. (Deprecated in OS X v10.4. Use Multilingual Text Engine instead; see Handling Unicode Text Editing With MLTE.)

void TEReplaceStyle (
   short mode,
   const TextStyle *oldStyle,
   const TextStyle *newStyle,

   TEHandle hTE
);
Parameters
mode

A selector that specifies which attributes to replace. It corresponds to any additive combination of the “Text Styling Constants” for font, character style, type size, color, and so forth.

oldStyle

A pointer to a text style structure that specifies the current character attributes to search for in the selected text.

newStyle

A pointer to a text style structure that specifies the new attributes to be set. This structure contains the character attributes to be applied to the current selection range based on the value of mode.

fRedraw

A flag that specifies whether or not TextEdit should immediately redraw the text to reflect the attribute changes. A value of FALSE delays redrawing until another event forces the update. A value of TRUE causes the text to be redrawn immediately using the new character attributes.

hTE

A handle to the multistyled edit structure containing the text selection whose character attributes are to be changed.

Discussion

The TEReplaceStyle function replaces any attribute in the current selection range that matches the attribute specified by oldStyle with that given by newStyle. Only the character attributes specified by mode are affected.

Attribute changes are made directly to the style elements (STElement) within the style table itself (TEStyleTable). If you specify the value doAll for the mode parameter, newStyle replaces oldStyle outright. The TEReplaceStyle function has no effect on a monostyled edit structure.

void TESetAlignment (
   short just,
   TEHandle hTE

Parameters
just

The alignment for the specified text.The default value of the just field of the edit structure is teFlushDefault. This means that text alignment is based on the primary line direction which is set by default according to the system script.

For a description of the values you can use in this parameter, see “Text Alignment Constants.”

hTE

A handle to the edit structure containing the text.

Discussion

For languages that are read from right to left, text is right aligned by default. For languages that are read from left to right, text is left aligned by default. If you change the alignment, call the Window Manager function InvalRect after TESetAlignment to redraw the text with the new alignment.

TextEdit does not support justified alignment. To draw justified text, use the QuickDraw Text functions.

void TESetClickLoop (
   TEClickLoopUPP clikProc,
   TEHandle hTE

Parameters
clikProc

A universal procedure pointer to the customized click loop function.

hTE

A handle to the edit structure whose clikLoop field is to be modified.

Discussion

The TESetClickLoop function lets you replace the default click loop function. The TEClick function repeatedly calls the function that the click loop field points to as long as the user holds down the mouse button within the text of the view rectangle. The default click loop function scrolls only the text. However, you can provide a customized click loop function that scrolls the text and the scroll bars in tandem.

If automatic scrolling is enabled, the default click loop function checks to see if the mouse has been dragged out of the view rectangle; if it has, the function scrolls the text using TEPinScroll. The amount by which TEPinScroll scrolls the text vertically is determined by the lineHeight field of the edit structure for monostyled text and the LHTable for multistyled text.

   long selEnd,
   TEHandle hTE

Parameters
selStart

The byte offset at the start of the text selection range. The selStart field can range from 0 to 32767.

If selStart equals selEnd, the new selection range is an insertion point, and a caret is displayed. If selEnd is anywhere beyond the last character of the text, TESetSelect uses the first position past the last character.

selEnd

The byte offset at the end of the text selection range. The selEnd field can range from 0 to 32767.

hTE

A handle to the edit structure.

Discussion

The TESetSelect function removes highlighting of the old selection range and highlights the new one.

When only the Roman script system is used, the selection range is always displayed and highlighted as a continuous range of text. However, when one or more script systems requiring mixed-directional display of text are installed, a continuous sequence of characters in memory may appear as a discontinuous selection when displayed.

TESetStyle

Sets new character attributes, in the specified edit structure, for the current selection range. (Deprecated in OS X v10.4. Use Multilingual Text Engine instead; see Handling Unicode Text Editing With MLTE.)

void TESetStyle (
   short mode,
   const TextStyle *newStyle,
   Boolean fRedraw,
   TEHandle hTE
);
Parameters
mode

A selector that specifies which character attributes are to be changed. The value for mode can be any additive combination of the mode constants for font, style, type size, color, and so forth. It corresponds to any additive combination of the “Text Styling Constants” for font, character style, type size, color, and so forth.

The value of mode specifies which existing character attributes are to be changed to the new character attributes specified by newStyle. If doToggle is specified along with doFace and if an attribute specified in the given newStyle parameter exists across the entire selected range of text, then TESetStyle removes that attribute. Otherwise, if the attribute doesn’t exist across the entire selection range, all of the selected text is set to include that character attribute.

newStyle

A pointer to a structure of type TextStyle that specifies the new attributes to be set. This structure contains the character attributes to be applied to the current selection range based on the value of mode.

fRedraw

A flag that specifies whether or not TextEdit should immediately redraw the affected text to reflect the new character attribute changes. A value of TRUE causes the text to be redrawn immediately. Line breaks, line heights, and line ascents are recalculated. A value of FALSE delays redrawing until another event forces the update.

If the fRedraw parameter is set to TRUE, TextEdit redraws the current selection range using the new character attributes, recalculating line breaks, line heights, and line ascents.

If the fRedraw parameter is set to FALSE, TextEdit does not redraw the text or recalculate line breaks, line heights, and line ascents. Consequently, when you call a function that uses any of this information, such as TEGetHeight (which returns a total height between two specified lines), it does not reflect the new character attributes set with TESetStyle. Instead, the function uses the information that was available before TESetStyle was called. To update this information, call the TECalText function. To be certain that the new information is always reflected, call TESetStyle with the fRedraw parameter set to TRUE.

hTE

A handle to the multistyled edit structure containing the selected text.

Discussion

The TESetStyle function has no effect on a monostyled structure.

If you call the TESetStyle function when the value of the selStart field of an edit structure equals the value of the selEnd field (specifying an insertion point), TextEdit stores the input character attributes in the null scrap structure pointed to by the null style handle.

The function TESetText lets you incorporate existing text into the text buffer of an edit structure. The function copies the specified text into the existing hText handle of the edit structure, resizing the buffer, if necessary it doesn’t bring in the original text. The copied text is wrapped to the destination rectangle, and its lineStarts and nLines fields are calculated accordingly. The selection range is set to an insertion point at the end of the incorporated text. The TESetText function does not display the copied text on the screen. To do this, call TEUpdate.

   const Rect *viewRect
);
Parameters
destRect

A pointer to the destination rectangle for the new edit structure, specified in the local coordinates of the current graphics port. This is the area in which text is laid out.

viewRect

A pointer to the view rectangle for the new edit structure, specified in the local coordinates of the current graphics port. This is the area of the window in which text is actually displayed.

Return Value

A handle to the newly created edit structure. Your application needs to store the handle to the edit structure that is returned; many functions require it as an input parameter. See the description of the TEHandle data type.

Discussion

A multistyled edit structure contains text whose attributes, including font, size, and style, can vary from character to character. Always use the TEStyleNew function to create an edit structure for text that uses varying character attributes. The TEStyleNew function sets the txSize, lineHeight, and fontAscent fields of the edit structure to –1, allocates a style structure, and stores a handle to the style structure in the txFont and txFace fields. The TEStyleNew function creates and initializes a null scrap that is used by TextEdit functions throughout the life of the edit structure.

Call TEStyleNew once for every edit structure you want allocated. Your application needs to store the handle to the edit structure that is returned; many functions require it as an input parameter.

If your application contains more than one window where text editing occurs, you need to create an edit structure for each window.

Before this function is called, the window must be in the current graphics port.

A handle to the edit structure into which the text is to be pasted.

Discussion

When you call TEStylePaste and there is no character attribute information associated with text in the desk scrap, TEStylePaste first checks the null scrap. If the null scrap contains character attribute information, this is used. If the null scrap is empty, TEStylePaste gives the text the same attributes as those of the first character of the replaced selection range or that of the preceding character if the selection is an insertion point.

For a monostyled edit structure, TEStylePaste pastes the text only; there is no associated character attribute information because all the text uses the same attributes.

void TEUseStyleScrap (

Parameters
rangeStart

The offset of the first character in the text of the edit structure to which the character attributes are to be applied.

rangeEnd

The offset of the last character in the text of the edit structure to which the character attributes are to be applied.

newStyles

A handle to a style scrap structure. The style scrap structure contains the attributes to be applied to the specified range of text. If the value of newStyles is NULL, no action is performed. Each element in the style scrap structure contains a field that is the offset of the beginning of the element’s character attributes. This field (scrpStartChar) defines the boundaries for the scrap’s style runs.

Depending on the requirements of your application, you can create a style scrap structure directly and pass its handle to TEUseStyleScrap as the value of newStyles or you can use a style scrap structure created by TEGetStyleScrapHandle.

fRedraw

A flag that specifies whether TextEdit should immediately redraw the selection range using the new character attributes. If the fRedraw parameter is set to TRUE, the attributes are applied immediately to the specified range of text, and line breaks, line heights, and line ascents are recalculated. If fRedraw is set to FALSE, the new character attributes are not reflected in the view rectangle until the next update event occurs.

hTE

A handle to the edit structure containing the range of text to which the character attributes are to be applied. If the handle points to a monostyled edit structure (created using TENew), no action is performed.

Discussion

The TEUseStyleScrap function writes the character attribute information into the style structure’s style table and updates the style run table.

Regardless of whether the text is redrawn, the current selection range is not changed; if characters are highlighted before TEUseStyleScrap is called, they remain highlighted after it is called. However, if characters within the current selection range also fall within the specified range of text, they are rendered in the new character attributes when the text is redrawn.

The TEUseStyleScrap function applies the first element’s attributes to the characters from rangeStart up to the scrpStartChar field of the next element. The function terminates without error if it prematurely reaches the end of the range or if there are not enough scrap style elements to cover the whole range. In the latter case, the function applies the last set of character attributes in the style scrap structure to the remainder of the range.
