How to affect a PageItem within an OnClick handler

[Suntanned]

Hi,

I'm trying to set the geometricBounds of a PageItem and that works fine until I do it within a button click handler, then nothing happens.

Code:

function createDialog(header, message, pageItem) {
     var dialog = new Window("dialog", header),
          textArea = dialog.add("statictext {preferredSize: [200, 100], properties: {multiline: true}}"),
          correctButton = dialog.add("button", undefined, "Correct");
     
     textArea.text = message;
     
     correctButton.onClick = function() {
          alert('Before');
          pageItem.geometricBounds = [1, 1, 8, 8];
          alert('After');
     }
     
     dialog.show()
}

Also, only the first alert pops up. 'After' is never shown.

Any ideas?

A dialog is a modal window. While it is active the script cannot "write" to indesign (it can read values from various objects, like those geometric bounds) but it cannot change them.
Solutions:
a) use a palette.

b) in the "onClick" handler record the geometric bounds, but only apply them once the dialog is closed:

  if (dialog.show()==1){pageItem.geometricBounds=myRecordedBounds;}

That makes sense.

Thanks so much for all the help !
