Composite setBounds on Canvas does not work on Mac [message #1702252]

Hello Experts,
I am using Eclipse 3.8 for my imaging application. The main image is displayed on a Canvas and to show the overview, I have added another composite on the Canvas. I am setting the Canvas layout to null and for the overview composite I try to set its bounds manually by calling setBounds method.

This works absolutely well for Windows. I see the overview composite at a desired place on Canvas. But for Mac and Linux, the overview canvas is not visible. Doing more investigation I see that the overview canvas is hidden behind Canvas.

Can you help me how I can solve the issue?

Thank you for your help.
Amey.

Hmm, I'm not an expert on SWT internals, but I've never tried embedding a Canvas as a child widget of a Canvas. I imagine you'd have more success if you instead hosted both Canvas widgets within a Composite with a null layout, and then explicitly managed the Z order with moveAbove() and moveBelow().
