多个关键事件绑定中的Tkinter - ＆QUOT;控制+ E＆QUOT; ＆QUOT;命令（苹果）+ E＆QUOT;等等 [英] Multiple Key Event Bindings in Tkinter - "Control + E" "Command (apple) + E" etc

问题描述

的Mac OS X 10.6.6 - Tkinter的

我要绑定多重要事件，而我发现了一个effbot文章和Tk的手册页，我已经无法正常完成这项工作。我是新来的。

我已经成败参半。我已经能够得到按住Shift +字母键，但并不能够控制或者命令（苹果键）。我真正想要做的是命令+字母和控制+字母键所以它会在Windows和OS X理论上的工作。

我希望它在窗口层面的工作，所以我用根。或许有更好的办法。下面是我已经试过：

  root.bind（'＆LT;移-E＆GT;'，自我pressedCmdE）＃工程
root.bind（E，自我。pressedCmdE）＃工程
root.bind（'＆LT;命令E＆GT;'，自我pressedCmdE）＃不起作用
＃root.bind（'＆LT; MOD1-E＆GT;'，自我pressedCmdE）##做MOD1，M1和
＃root.bind（'＆LT; M1-E＆GT;'，自我pressedCmdE）##命令意味着同样的事情？

奇怪的是，当我preSS ALT /选项+（E，N，或其他人）它创建了一个错误。难道是与PythonLauncher交互？

解决方案

这似乎是一个塔卡错误。我得到的MAC以及使用Python / Tkinter的的Tcl / Tk同样的错误。您可以绑定＆LT;命令E＆GT; 来一个小部件（我试着用一个文本组件），但它绑定到根窗口或所有似乎会导致你的错误。

Mac OS X 10.6.6 - Tkinter

I want to bind multiple-key events, and while I have found an effbot article and the Tk man pages, I've been unable to make this work correctly. I'm new here.

I've had mixed success. I've been able to get Shift + letter key, but not Control or Command (Apple key). What I really want to do is Command + letter and Control + letter key so it would theoretically work in Windows and OS X.

I want it to work at window-level, so I'm using root. Perhaps there is a better way. Below is what I've tried:

root.bind('<Shift-E>', self.pressedCmdE)   # Works
root.bind('e', self.pressedCmdE)           # Works
root.bind('<Command-E>', self.pressedCmdE) # Does Not Work
#root.bind('<Mod1-E>', self.pressedCmdE)   #   # Do Mod1, M1, and
#root.bind('<M1-E>', self.pressedCmdE)     #   # Command mean the same thing?

Strangely, when I press alt/option + (E, N, or others) it creates an error. Is it interacting with PythonLauncher?

解决方案

This appears to be a bug in Tk. I get the same error with tcl/tk on the mac as well as with python/tkinter. You can bind <Command-e> to a widget (I tried with a text widget) but binding it to the root window or to "all" seems to cause the error you get.
