Re: How do I make sure Widgets receive mouse events if placed in front of a Canvas or Vaadin DrawingArea?

Use z-index CSS property to set the depth of your widgets. Higher z-index would get priority

This used to work on Firefox in GWT 2.3 on Window XP, but now on Chrome and IE with GWT 2.4 and Windows Vista I can't make my Widgets, which are in front of a Canvas (or Vaadin DrawingArea), receive any mouse events at all.

A widget is placed in front of the drawing surface like so:

absolutePanel.add(canvas); //drawing surface, whether it's a Canvas or Vaadin DrawingArea

absolutePanel.setWidgetPosition(canvas, 0, 0);

absolutePanel.add(myWidget);

absolutePanel.setWidgetPosition(myWidget, 0, 0);

If I do not add the "canvas", "myWidget" receives its mouse events fine.

How do I make sure "myWidget" can receive all its mouse events properly in this scenario?
