1631 | In order to avoid asking for motion events and then throwing most | |
1632 | of them away or busy-polling the server for mouse positions, we ask | |
1633 | the server for pointer motion hints. This means that we get only | |
1634 | one event per group of mouse movements. "Groups" are delimited by | |
1635 | other kinds of events (focus changes and button clicks, for | |
1636 | example), or by XQueryPointer calls; when one of these happens, we | |
1637 | get another MotionNotify event the next time the mouse moves. This | |
e5d77022 | 1638 | is at least as efficient as getting motion events when mouse |
90e65f07 JB |
1639 | tracking is on, and I suspect only negligibly worse when tracking |
1640 | is off. | |
1641 | ||
1642 | The silly O'Reilly & Associates Nutshell guides barely document | |
1643 | pointer motion hints at all (I think you have to infer how they | |
1644 | work from an example), and the description of XQueryPointer doesn't | |
1645 | mention that calling it causes you to get another motion hint from | |
1646 | the server, which is very important. */ | |
