如何获得 Tkinter Mac 友好的菜单快捷方式(cmd+key) [英] How to get Tkinter Mac-friendly menu shortcuts (cmd+key)

问题描述

我正在考虑 Tkinter 菜单标签(命令)的快捷方式.在 Mac 上，与 cmd ⌘ 的组合很常见.

I am considering shortcuts for Tkinter menu labels (commands). On Macs the combination with cmd ⌘ is common.

到目前为止，我只找到了 self.bind_all("", self.quit).如何实现 cmd ⌘ 快捷键?

So far I have found only self.bind_all("<Control-q>", self.quit). How to implement cmd ⌘ shortcuts?

然后再想一想 - 一旦应用程序完成 - 将其转换为适用于 Windows 和 Mac 应用程序的可执行文件可能会在使用 cmd ⌘ 时造成困难?处理此问题的最佳方法是什么?

Then again, thinking about - once the app is finished - translating it to an executable file for Windows and a Mac application might cause difficulties when using cmd ⌘? What is the best way of dealing with this issue?

推荐答案

我认为您需要指定 Tk 内置命令 -- 也许是 Mod1 而不是 控制.您可能还会发现此 Tk 识别的键符 的列表很有用.

I think you would need to specify one of the Meta and M Modifiers listed at Tk Built-in Commands -- perhaps Mod1 instead of Control. You might also find this list of keysyms recognized by Tk useful.

虽然我从来没有真正尝试过——如果一切都失败了——你也许可以通过编写自己的事件处理函数来确定你需要知道什么def handlerName(event):，将其绑定到 '' 事件，然后，在函数 print 中传递传递给它的事件参数的属性值当它被调用时——例如 event.keycode、event.keysym、event.keysym_num 等——从而让你看到要做什么用于检测 Mac 上的 ⌘ 键修改按键.

Although I've never actually every tried to do it -- if all else fails -- you might be able to determine what you need to know by writing your own event handler function def handlerName(event):, bind it to '<Any-KeyPress>' events, and then, in the function print the values of the attributes of the event argument being passed it when it's called -- such as event.keycode, event.keysym, event.keysym_num, etc -- thereby allowing you to see what to use for detecting ⌘-key modified keystrokes on your Mac.

最后，Python 是开源的，因此您可以随时尝试阅读.

Lastly, Python is open-source, so you can always try reading that.

更新:从这个 answer 中的代码看来，Command- 会起作用.

Update: From the code in this answer it sounds like the Command- would work.
