The way Mangler detects mouse button presses is by polling the state of the
mouse. With most mouses, polling the master pointer will return the state of
the slave device. This problem seems to be limited to Logitech wireless mice.
Basically we're doing this:
dev = XOpenDevice(GDK_WINDOW_XDISPLAY(rootwin), xdev[ctr].id);
xds = (XDeviceState *)XQueryDeviceState(GDK_WINDOW_XDISPLAY(rootwin), dev);
xbs = (XButtonState*) xds->data;
state = state << bit;
if ((xbs->buttons[byte] & state) >> bit) { // byte and bit are the mouse
button flags
// button is pressed
}
I have tried other wireless mouse devices at my disposal and they seem
to work fine. It is ONLY the logitech wireless mice (at least... that
have been reported)
