TEUpdate

The TEUpdate procedure draws the specified text within a given update rectangle.

PROCEDURE TEUpdate (rUpdate: Rect; hTE: TEHandle);

rUpdate

The update rectangle, given in the coordinates of the current graphics port, where the specified text is to be drawn.

hTE

A handle to the edit record containing the text to be drawn.

DESCRIPTION

Call TEUpdate every time the Event Manager function WaitNextEvent reports an update event for a text editing window--after you call the Window Manager procedure BeginUpdate, and before you call the EndUpdate procedure. You also need to erase the update region with the EraseRect procedure. If you don't the caret can sometimes remain visible when the window is deactivated.
