I would like to write an application that would collect mouse events
(Button Press/Release) among all windows/screens in the same desktop,
and display the event info on a dedicated window. I used the following
two methods but none worked. Your help is appreciated.
Method 1:
d = XOpenDisplay(display_name);
s = XDefaultScreen(d);
root = RootWindow(d,s);
XSelectInput(d, root, ButtonPressMask);
while(1)
{
XNextEvent(d, &ev);
switch(ev.type)
{
case ButtonPress:
...
In this method, program is hanging on waiting for XNextEvent. Since
SelectInput is on root window, and no ButtonPress is detected on that
window. How can I get the events from the window a mouse is presenting?
Method 2:
Use the function Select_Window( display) to select the current mouse
pointed window and leads grab all events on the entire screen, however,
the normal mouse function won't work till the program is done.
Thanks,
