| 20 | <dt><b>oop_tcl_new</b> |
||
| 21 | <dd>Create a liboop source which uses the |
||
| 22 | <a href="http://www.purl.org/tcl/home/man/tcl8.3.2/TclLib/DoOneEvent.htm">Tcl |
||
| 23 | event loop</a> for events. There is only one such event loop, so this |
||
| 24 | function is global. You may call it multiple times; it will return the same |
||
| 25 | event source, but keep count of the number of users.<p> |
||
| 26 | |||
| 27 | Events will be dispatched when the Tcl event loop is run, either directly |
||
| 28 | via Tcl_DoOneEvent() or indirectly via Tk_MainLoop(). Unfortunately, there |
||
| 29 | is no way to stop the Tcl event loop, so return values from event handlers |
||
| 30 | are ignored.<p> |
||
| 31 | |||
| 32 | <dt><b>oop_tcl_delete</b> |
||
| 33 | <dd>Delete the liboop source created with oop_tcl_new(). This decrements the |
||
| 34 | count of users; when oop_tcl_delete has been called as many times as |
||
| 35 | oop_tcl_new, the event source is removed.<p> |
