I created this yummy text box entry placeholder for CS4 on my Mac:
but for some reason this fails to draw correctly on Windows! If the edit box is active and the cursor is in it, the text is not drawn but the cursor blinks at correct position at the end of that invisible text. Moving the cursor or typing in something makes the text pop back into view. (Sorry, should have thought of making a 'shot of that as well.) A real shame, because on my Mac it works as I meant it to: placeholder text shows when the field is inactive and empty, placeholder disappears when you enter the field and type anything in it. Delete text and leave box makes it appear again.
Is this an error in my code (silently corrected on the Mac but showing up on 'the other platform'), or is it an error on the Windows' Side of the world? Or is this just something one should not be messing with using ScriptUI? (A fairly reasonable explanation.) Or might it work correctly on CS5 for both platforms? (In which case I could put in a platform/version check -- "no fancy dialog for you, you Older Version on a Microsoft Platform!").
I also have a variant of same code that would underline static text, which also shows up correctly on Mac and not-at-all on Windows -- but then it may be failing for the very same reason.
My code:
var w = new Window ("dialog", "Display Placeholder");
w.bg = w.graphics.newBrush(w.graphics.BrushType.SOLID_COLOR,[1,1,1]);
w.textPen = w.graphics.newPen(w.graphics.PenType.SOLID_COLOR,[0.67,0.67,0.67], 1);
with(w.add ("group")){ add ("statictext", undefined, "Text"); editbox = add ("edittext", undefined, ''); editbox.characters = 32; editbox.onDraw = function(d) { if( this.text || this.active) this.parent.onDraw(d) else { this.graphics.rectPath (0,0,this.size.width,this.size.height); this.graphics.fillPath(w.bg); this.graphics.drawString("<required>",w.textPen,0,0,this.graphics.font); } };}
