06a2c219 | 232 | Formerly, we used PointerMotionHintMask (in standard_event_mask) |

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