06a2c219 | 233 | Formerly, we used PointerMotionHintMask (in standard_event_mask) |

234 | so that we would have to call XQueryPointer after each MotionNotify |
235 | event to ask for another such event. However, this made mouse tracking | |
236 | slow, and there was a bug that made it eventually stop. | |
237 | ||
238 | Simply asking for MotionNotify all the time seems to work better. | |
239 | ||
69388238 RS |
240 | In order to avoid asking for motion events and then throwing most |
241 | of them away or busy-polling the server for mouse positions, we ask | |
242 | the server for pointer motion hints. This means that we get only | |
243 | one event per group of mouse movements. "Groups" are delimited by | |
244 | other kinds of events (focus changes and button clicks, for | |
245 | example), or by XQueryPointer calls; when one of these happens, we | |
246 | get another MotionNotify event the next time the mouse moves. This | |
247 | is at least as efficient as getting motion events when mouse | |
248 | tracking is on, and I suspect only negligibly worse when tracking | |
