Hello,

I have started to learn how to create shaped, non-rectangular windows
with the XShape* functions.

I can now create a shaped main window. I set or create a bitmap mask for
it and display the window. This solutions works very well, even when I
use Cairographics to draft the window's shape. I mostly use XLib though.

See an example 1 (moma's posting):

Now, want to go further.

I have tried to create a shaped main-window and put some shaped child
controls (child windows) on it. But I cannot make it work (the child
windows ar enot visible) because I do not understand all the
intricatenesses of the XShape* functions.

XShape* functions:

Please, tell me how to do it (a non-rectangular main-window with many
non-rectangular child controls). Can you provide an example?

Do I have to sum up the masks of childwindows and put it on the
main-window?

Help and you will get a the code in return :-)

TIA.
