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

12144 | system events plus a few simple menu events. They also set up |

12153 | mac_read_socket (defined further below) to read input. This is | |
12154 | where WaitNextEvent is called to process Mac events. This is also | |
12155 | where check_alarm in sysdep.c is called to simulate alarm signals. | |
12156 | This makes the cursor jump back to its correct position after | |
12157 | briefly jumping to that of the matching parenthesis, print useful | |
12158 | hints and prompts in the minibuffer after the user stops typing for | |
