261 | Formerly, we used PointerMotionHintMask (in standard_event_mask) | |
262 | so that we would have to call XQueryPointer after each MotionNotify | |
263 | event to ask for another such event. However, this made mouse tracking | |
264 | slow, and there was a bug that made it eventually stop. | |
265 | ||
266 | Simply asking for MotionNotify all the time seems to work better. | |
267 | ||
268 | In order to avoid asking for motion events and then throwing most | |
269 | of them away or busy-polling the server for mouse positions, we ask | |
270 | the server for pointer motion hints. This means that we get only | |
271 | one event per group of mouse movements. "Groups" are delimited by | |
272 | other kinds of events (focus changes and button clicks, for | |
273 | example), or by XQueryPointer calls; when one of these happens, we | |
274 | get another MotionNotify event the next time the mouse moves. This | |
275 | is at least as efficient as getting motion events when mouse | |
276 | tracking is on, and I suspect only negligibly worse when tracking | |

12234 | where check_alarm in sysdep.c is called to simulate alarm signals. | |
