Setting Composite Background color [message #909288] Thu, 06 September 2012 22:04 Go to next message

Hi,

I got stuck trying to set the background color of a composite. This composite (Composite A) lives inside another composite (Composite B).

I have set the background mode of composite A and B to SWT.INHERIT_DEFAULT. Also, I have set the WidgetUtil.CUSTOM_VARIANT of Composite B to a special CSS style and it works fine. Now, I try to set Composite A with another CSS style by using the custom variant, but the desired background color never showed up.

With all the code above and a hard call "setBackground(Color)", I can set the color to the one I want. But with CSS and custom variant, I can't do the same thing.

Is there any material which explains more about the background mode? Or if you can think of anything that I can try to get around the problem?

Thanks.

Seems like setting SWT.INHERIT_NONE on the parent composite does the trick. Thanks.

Hi Ronald,

I've noticed that the default background color of Composites is
currently set to "transparent" in the default theme, making Composites
inherit their parent's bg color. I've opened a bug [1] for this issue.

I guess this is the same problem you noticed.

Regards, Ralf

Thanks Ralf. I don't think I am affected by this bug but it's good to know. After setting the parent composite to SWT.INHERIT_NONE, I can set the color of the child composite to the color I defined in my CSS file.
