I have an application that is used as a control system for a presentation, under Linux and using X11. I have a USB presentation remote that acts as a very miniature keyboard (four buttons: Page Up, Page Down, and two others) which can be used to advance and go back in the presentation. I would like to have my presentation application to receive all of the events from this remote regardless of where the mouse focus is. But I would also like to be able to receive the normal mouse and keyboard events if the current window focus is on the presentation application. Using XIGrabDevice() I was able to receive all events from the remote in the presentation application regardless of the current focus but I was not able to receive any events from the mouse or other keyboard while the grab was active. Is what I'm trying to do possible?
Here's the code I'm using: XIEventMask masks[1]; unsigned char mask[(XI_LASTEVENT+7)/8]; memset(mask, 0, sizeof(mask)); XISetMask(mask, XI_KeyPress); masks[0].deviceid = XIAllMasterDevices; masks[0].mask_len = sizeof(mask); masks[0].mask = mask; Status result = XIGrabDevice(dpy, deviceid, win, CurrentTime, None, XIGrabModeAsync, XIGrabModeAsync, True, masks); Any help would be appreciated. Thank you. Eric
