Here is an example that shows how to check which monitor/display a GUI object is being shown on:
def get_monitor_index_swt(swt_widget):
m = swt_widget.monitor
monitors = swt_widget.display.getMonitors()
for i in range(monitors.length):
if m == monitors.at(i):
return i
return -1
def main():
#...
o = waitForObject({"isvisible": True, "type": "org.eclipse.swt.widgets.Table"})
idx = get_monitor_index_swt(o)
test.log("Widget is on monitor/display #%s" % idx)
