I tried this but unfortunately to no avail!
I did it as follows:
canvas.addStyleName("behind");
absolutePanel.add(canvas); //drawing surface, whether it's a Canvas or
Vaadin DrawingArea
absolutePanel.setWidgetPosition(canvas, 0, 0);
myWidget.addStyleName("inFront");
absolutePanel.add(myWidget);
absolutePanel.setWidgetPosition(myWidget, 0, 0);
..where CSS file says:
.behind{
z-index:-1;
}
.inFront{
z-index:1;
}
Problem remains even if I change z-indexes to, say, 1 and 4, respectively,
or -100 and 100. So the z-indexing was probably not the cause of the
Widgets not getting the mouse events. Any ideas of how I'd make sure they
do? Are you able to get this to work?
