在其窗口已显示后更改 ScriptUI 控件

Question

So I have a (hopefully) simple one this time. I have a ScriptUI window programmed in ExtendScript for Adobe InDesign CS6. It contains a StaticText control. After this dialog window is shown to the user, I would like to change the text of that StaticText control based upon some action the user takes. Here is a very simplified version of my problem:

var w = new Window("dialog");
    var t = w.add("statictext", undefined, "Hello");

w.show();

t.text = "Good evening";

In the above example, "Hello" never changes to "Good evening". I have discovered, however, that if I add a Progress Bar control to this window and update it periodically along with the StaticText control, it WILL allow the text to change, but then the text gets truncated if the second line is longer than the original text.

It's as though the width of the StaticText control is set at creation time and can never ever be changed after its window is shown. If this is simply a limitation of ScriptUI, just let me know and I'll deal with it. Otherwise, please tell me if there's anything I can do to have that StaticText change dynamically and accept longer lines of text without getting truncated. Thanks!

Answer 1

Try setting multiline to true :

var w = new Window("dialog");
    var t = w.add("statictext", undefined, "Hello", {multiline:true});

w.show();

t.text = "Good evening";

That should prevent the text from getting truncated after the first line.

You can test it by adding return characters ( \\r or \\n ) to your text string:

t.text = "Good\revening"

This is the structure I usually use [EDIT: Actually, this shows it off a little better]:

//global:
var n=1;
//////////////////////////

function doTextChange(target, newText) {
    target.text = newText;
}

var win = new Window('dialog', 'dialog',[300,100,645,396]);
var w = buildUI();
if (w != null) {
    w.show();
}

function buildUI() {
    if (win != null) {
         win.t = win.add("statictext", [14,15,314,37], "Hello");
         win.closeBtn = win.add('button', [240,210,320,232], 'Close', {name:'Cancel'});
         win.changeBtn = win.add('button', [240,210+33,320,232+33], 'Change', {name:'Cancel'});
         win.closeBtn.onClick = function () { this.parent.close(1) };
         win.changeBtn.onClick = function () { n++;doTextChange(  win.t, "Good evening " + n);};
    }
    return win
}
