Hi:
I don't know if you understand my requirement.I want a subregion of the window \
transparent.That is to say, I use XClearArea to make an area show the background of \
the window.I want to set the background of the window transparent.So, I can get a \
subregion that is transparent.I want to use this region to show the content under the \
window.Xshape is not suit for me.because the events of that region I still want to \
use.

In case you want a *transparent* (invisible) window, pass InputOnly as "class" \
parameter to XCreateWindow http://tronche.com/gui/x/xlib/window/XCreateWindow.html
If you want a *translucent* (partially transparent/translucent content) window you \
require a running compositor (to see the translucency) You'll also have to provide \
correct visual and colormap, see eg. here: \

Cheers,
