问题
I have a ARGB image data. I wish to set my window icon to this data. After searching for hours I am still at the start with nothing at hand. I know that I need to create a pixmap for image data and (may be) another pixmap for mask and use hints to hint the window manager about this. However, I do not know how to setup 32bit ARGB or 24bit RGB + 8bit alpha image. A sample would really be nice.
回答1:
If 32 bit depth visual is available (check xdpyinfo) then code from my question should work for you. After you create RGBA pixmap just assign it's handle to _NET_WM_ICON property

I stumbled upon this thread after quite some investigation on the topic, and I wasn't even able to get example code working on my system.
Turns out the buffer needs to be long and not int on 64 bit systems.
Corrected exampled below
/* gcc -Wall -Wextra -Og -lX11 -lstdc++ -L/usr/X11/lib -o native foo.c */
#include <stdlib.h>
#include <X11/Xlib.h>
int main( int argc, char **argv )
{
unsigned long buffer[] = {
