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,
Thomas
