Working with ScriptUI
JavaScripts can make create and define user-interface elements using an Adobe scripting component named ScriptUI. ScriptUI gives scripters a way to create floating palettes, progress bars, and interactive dialog boxes that are far more complex than InDesign’s built-in dialog
object.
This does not mean, however, that user-interface elements written using Script UI are not accessible to
AppleScript users. InDesign scripts can execute scripts written in other scripting languages using the do script method.
Creating a progress bar with ScriptUI
The following sample script shows how to create a progress bar using JavaScript and ScriptUI, then use the progress bar from an AppleScript (for the complete script, see ProgressBar):
C HAPTER 7: User Interfaces Working with ScriptUI 137
#targetengine "session"
//Because these terms are defined in the "session" engine,
//they will be available to any other JavaScript running
//in that instance of the engine.
var myMaximumValue = 300; var myProgressBarWidth = 300; var myIncrement = myMaximumValue/myProgressBarWidth; myCreateProgressPanel(myMaximumValue, myProgressBarWidth); function myCreateProgressPanel(myMaximumValue, myProgressBarWidth){ myProgressPanel = new Window('window', 'Progress'); with(myProgressPanel){ myProgressPanel.myProgressBar = add('progressbar', [12, 12, myProgressBarWidth, 24], 0, myMaximumValue);
}
}
The following script fragment shows how to call the progress bar created in the above script using an
AppleScript (for the complete script, see CallProgressBar): set myDocument to make document
--Add pages to the active document.
--If you don't do this, the progress bar will
--go by too quickly.
--Note that the JavaScripts must use the "session"
--engine for this to work.
set myJavaScript to "#targetengine \"session\"" & return set myJavaScript to myJavaScript & "myCreateProgressPanel(100, 400);" & return set myJavaScript to myJavaScript & "myProgressPanel.show();" & return do script myJavaScript language javascript repeat with myCounter from 1 to 40 set myJavaScript to "#targetengine \"session\"" & return set myJavaScript to myJavaScript & "myProgressPanel.myProgressBar.value = " set myJavaScript to myJavaScript & myCounter & "/myIncrement;" & return do script myJavaScript language javascript tell myDocument to make page if myCounter = 100 then set myJavaScript to "#targetengine \"session\"" & return set myJavaScript to myJavaScript &
"myProgressPanel.myProgressBar.value = 0;" & return set myJavaScript to myJavaScript & "myProgressPanel.hide();" & return do script myJavaScript language javascript close myDocument saving no end if end repeat
