WA_TranslucentBackground can't capture mouse event

[Qingshui Kong]

Hello everyone,

I have a problem. Could somebody give me some advise?

I create a dialog. I want it to be transparent. So I set the attribute WA_TranslucentBackground. It works as expected.

But it couldn't capture mouse event in the region that is transparent.

Does somebody know the solution? Could you tell me, please?

Thanks.

My enviroment:
Windows 7

Not possible directly. Just a thought. Can you try setting the background color on your own with minimum opacity value ?

Thanks you.

I want to say it works on Ubuntu 16.04.

I don't know your meaning by setting background color actually.
I have tried this code. But it's black.
QPalette pal = palette();
pal.setColor(QPalette::Background, QColor(0x00,0xff,0x00,0x00));
setPalette(pal);

On Windows, I got the same problem. The top level window with WA_TranslucentBackground cannot receive mouse pressing and releasing events when setMouseTracking to true.
