Problem with masking

[JANETTA]

Hi,

There's not yet much activity, but I hope someone reads this forum

I tried to create a masked widget on Maemo 5, Qt 4, just like the shapedclock demo in Qt demos. On S60 it looks ok (not perfect , but it is masked and the problems in there are different) and also on Linux. But on Maemo it takes the whole screen and masking makes the corners black. The same effect can be seen with shapedclock.

Does anyone know what is the problem and any hints how it could be avoided?

Thanks, I'll look into that.

I guess the problem is that the maemo-windowsmanager makes some assumptions for optimizations. That is that the application runs in fullscreen and covers all pixels and that there is nothing sensible to be able to shine through.

Even if you get it somehow to work, it will not fit very well into a maemo environment.

Axeljaeger, what do you mean by the last sentence, that it wouldn't fit well into Maemo environment even if I got it working? Do you mean application type or what?

At least on maemo4, an application fills the whole screen. If you mask something out, what shall be shown in the masked out pixels? The background image? There is no concept of window stacking to see other windows "beneath"

[JANETTA]

Ok, now I understand. So I guess that, for example the kind of application that was in the link posted by nayan_trivedi would be impossible on maemo. It's a pity...

I think it might be possible but you are not a good maemo citizen then. It's like you create an application with macos window decoration for vista. You can do it, you might like it, but you don't fit into the plattform.

[JANETTA]

Ok I think I need to learn more about the philosophy of maemo to become a better citizen and to get those silly ideas out of my head

Kimmo has answered this question:

Also you can create window, which doesn't take whole screen area using window of the type: Qt::WType_Popup.

Thanks for the hint.

I can't try it right now, because I don't have working Maemo environment at the moment, but I'll look into it when I can.
