| 7 twisted.internet.wxreactor is probably a better choice. | |
| 8 | |
| 9 To use:: | |
| 10 | |
| 11 | # given a wxApp instance called myWxAppInstance: | |
| 12 | from twisted.internet import wxsupport | |
| 13 | wxsupport.install(myWxAppInstance) | |
| 14 | |
| 15 Use Twisted's APIs for running and stopping the event loop, don't use | |
| 16 wxPython's methods. | |
| 17 | |
| 18 On Windows the Twisted event loop might block when dialogs are open | |
| 19 or menus are selected. | |
