This module integrates Tkinter with twisted.internet's mainloop.
|
||
|
|
|
||
|
|
Maintainer: Itamar Shtull-Trauring
|
||
|
|
|
||
|
|
To use, do::
|
||
|
|
|
||
|
|
| tksupport.install(rootWidget)
|
||
|
|
|
||
|
|
and then run your reactor as usual - do *not* call Tk's mainloop(),
|
||
|
|
use Twisted's regular mechanism for running the event loop.
|
||
|
|
|
||
|
|
Likewise, to stop your program you will need to stop Twisted's
|
||
|
|
event loop. For example, if you want closing your root widget to
|
||
|
|
stop Twisted::
|
||
|
|
|
||
|
|
| root.protocol('WM_DELETE_WINDOW', reactor.stop)
|
||
|
|
|
||
|
|
When using Aqua Tcl/Tk on macOS the standard Quit menu item in
|
||
|
|
your application might become unresponsive without the additional
|
||
|
|
fix::
|
||
|
|
|
||
|
|
| root.createcommand("::tk::mac::Quit", reactor.stop)
|
||
|
|
|
||
|
