181 | Formerly, we used PointerMotionHintMask (in STANDARD_EVENT_MASK) |
182 | so that we would have to call XQueryPointer after each MotionNotify | |
183 | event to ask for another such event. However, this made mouse tracking | |
184 | slow, and there was a bug that made it eventually stop. | |
185 | ||
186 | Simply asking for MotionNotify all the time seems to work better. | |
187 | ||
69388238 RS |
188 | In order to avoid asking for motion events and then throwing most |
189 | of them away or busy-polling the server for mouse positions, we ask | |
190 | the server for pointer motion hints. This means that we get only | |
191 | one event per group of mouse movements. "Groups" are delimited by | |
192 | other kinds of events (focus changes and button clicks, for | |
193 | example), or by XQueryPointer calls; when one of these happens, we | |
194 | get another MotionNotify event the next time the mouse moves. This | |
195 | is at least as efficient as getting motion events when mouse | |
196 | tracking is on, and I suspect only negligibly worse when tracking | |
