Re: [platform-swt-dev] Non Rectangular Custom Widget - Focus Problem

[Randy Hudson <hudsonr@xxxxxxxxxx>]

Only Shells can be non-rectangular (see
setRegion).  Even if you use Draw2d figures, the Canvas must still
be rectangular.
The best you can do is to match the
parent and child's background colors to give the illusion of some other
shape.

Please use the SWT newsgroup for questions
about the usage of SWT.

Do SWT widgets have anything similar to AWT Component's contains() method
for detecting mouse click events?

I have developed a non-rectangular (Rounded Corner) button using the draw2d
Clickable class. I detect mouse events in the button using the contains()
method of the draw2d Clickable object.  I have placed the Clickable
object
on a SWT Canvas using an instance of LightWeightSystem.

As the button is non-rectangular, when I click outside the button (but
on
the containing canvas), the canvas detects the mouse event and gives focus
to the button (causing it to draw focus). Is there a way to change the
behavior of the Canvas, so it only gets focus when clicked in a specific
area, and not the entire canvas area.

Also, is there an implementation of a custom RoundedCornerButton widget
in
SWT that I might be able to use?

Thanks!
