143 | Formerly, we used PointerMotionHintMask (in standard_event_mask) | |
144 | so that we would have to call XQueryPointer after each MotionNotify | |
145 | event to ask for another such event. However, this made mouse tracking | |
146 | slow, and there was a bug that made it eventually stop. | |
147 | ||
148 | Simply asking for MotionNotify all the time seems to work better. | |
149 | ||
150 | In order to avoid asking for motion events and then throwing most | |
151 | of them away or busy-polling the server for mouse positions, we ask | |
152 | the server for pointer motion hints. This means that we get only | |
153 | one event per group of mouse movements. "Groups" are delimited by | |
154 | other kinds of events (focus changes and button clicks, for | |
155 | example), or by XQueryPointer calls; when one of these happens, we | |
156 | get another MotionNotify event the next time the mouse moves. This | |
157 | is at least as efficient as getting motion events when mouse | |
158 | tracking is on, and I suspect only negligibly worse when tracking | |
159 | is off. */ | |
