After a little more testing:
- - focus-in-event and focus-out-event are emitted from the canvas when
I focus in or out with the cursor keys, but focus-in-event is not
emitted when I click on the canvas.
- - key-press-event is emitted when the canvas is focussed.
- - I disabled all GnomeCanvasItemClass->event handlers in my custom
canvas items, but to no effect.
So something is preventing focussing with the mouse. Could anyone
suggest what might be the cause, or how to find out what the cause
might be?
Many thanks,
Roger
