Tampering with parent window's transparency.

[Ivan Vilata i Balaguer]

Hi list,

I have tried to use rxvt-unicode with transparency under Ion, but Rxvt
mangles the window manager so that it also makes the title bar
transparent!  Here are two screenshots of another user:

I think the reason is Rxvt making *parent* windows transparent, as
explained in http://wiki.ael.be/ion/?Transparency.  This seems to be a
problem inherited from the original Rxvt.  Is it necessary to do that?
I found that the following patch solves the problem:

-              XClearWindow (disp, TermWin.parent[n]);
-            }
+          XSetWindowBackgroundPixmap (disp, TermWin.parent[0], ParentRelative);
+          XClearWindow (disp, TermWin.parent[0]);
 
           XSetWindowBackgroundPixmap (disp, TermWin.vt, ParentRelative);
           am_transparent = 1;

Maybe I amb completely wrong (I know nothing about low-level X
programming), but at least it works.

Please CC me your responses, since I am not in the list.

Thanks a lot!
