<Default Nav Button Set>

You can use the <Default Nav Button Set> command to specify a default navigation button set that Apple Guide uses for all sequences in your guide file unless you override the default by using a <Seq Nav Button Set> command.

<Default Nav Button Set> navButtonSetName

navButtonSetName

A string specifying the name of the navigation button set to use as the default. You can use the constant NONE to indicate that Apple Guide should display no navigation buttons (other than the navigation arrows) by default.

DESCRIPTION

The <Default Nav Button Set> command defines the default set of navigation buttons (in addition to the navigation arrows) that Apple Guide displays for your guide file. You can define a navigation button set for specification in the navButtonSetName parameter using a <Define Nav Button Set> command.

Note that any navigation buttons that you define using a <Define Nav Button Set> command appear to the left of the navigation arrows. Apple Guide always displays the navigation arrows on each panel. For each panel, Apple Guide makes the right navigation arrow active or inactive according to whether the user can navigate to a following panel. Apple Guide makes the left navigation arrow active or inactive according to whether the user can navigate to a previous panel. Apple Guide also displays the panel number (as it appears in a sequence) between the left and right navigation arrows.

The file Standard Setup is provided with Guide Maker. This file contains descriptions of the Huh? and GoStart navigation buttons, and defines three navigation button sets:

• "Standard Nav Bar". A navigation button set that specifies the GoStart and Huh? navigation buttons as buttons in the navigation bar.
• "GoStart Only". A navigation button set that specifies only the GoStart navigation button as a button in the navigation bar. The GoStart button resembles a lightbulb.
• "Huh? Only". A navigation button set that specifies only the Huh? navigation button as a button in the navigation bar.

The Standard Setup file also defines the "Standard Nav Bar" button set as the default navigation button set. If you include the Standard Setup file in your build file, you can automatically use these three navigation button sets as needed in your source files.

SPECIAL CONSIDERATIONS

The <Default Nav Button Set> command should appear only once in your source files. If you omit this command (or provide the constant NONE as a parameter), Apple Guide by default displays no navigation buttons for your guide file (but does display the left and right navigation arrows).

EXAMPLES

#use GoStart Only as default
<Default Nav Button Set> "GoStart Only"
#or use Huh? Only as default
<Default Nav Button Set> "Huh? Only"
#or use both GoStart and Huh? as default
<Default Nav Button Set> "Standard Nav Bar"
#or use no nav buttons by default
<Default Nav Button Set> NONE
#or use your own default navigation button set
<Default Nav Button Set> "my default nav buttons"
