如何绑定到<Up>的Release<向下>或 Tkinter 中的其他键盘事件? [英] How to bind to the Release of <Up> <Down> or other keyboard events in Tkinter?
问题描述
我可以在 Tkinter 中绑定到Up"和Down"事件,但我可以弄清楚如何绑定到这些事件的发布?
Im able to bind to "Up" and "Down" events in Tkinter, but i can figure out how to bind to the release of these events?
我正在做类似的事情:
Listbox.bind("<Up>", Update)
但这给了我列表框选择之前按下向上/向下键(如预期).有谁知道如何绑定到按键的释放?
But this is giving me the listbox selection before the Up/Down key was pressed (as expected). Does anyone know how to bind to the release of a key press?
提前致谢!
推荐答案
您可以使用 KeyPress-
或 KeyRelease-
前缀键事件.例如
.
You can prefix key events with KeyPress-
or KeyRelease-
. For example <KeyRelease-Up>
.
如果您尝试使用它来获取选择,最好绑定到 <<
,它总是在选择更改后触发.
If you're trying to use this to get the selection, you are better off binding to <<ListboxSelect>>
which always fires after the selection has changed.
