<div>Hi all</div>
<div>Windows and pixmaps together are known as drawables. Now I get a "drawable" ID(Created by XCreateWindow or XCreatePixmap) , I want to know how to distinguish them, that is to say how to distinguish if a "drawable ID" is a pixmap ID or window ID.</div>
<div>It seems that I didn't find any Xlib interface to achieve this. Are there any good method to use?</div>
<div>Thank you</div>
