PyObjC和TKinter的集成问题 [英] Integration issue with PyObjC and TKinter

问题描述

以下简单代码:

from PyObjCTools import AppHelper
import AppKit
import Tkinter

class App(AppKit.NSApplication):

    def finishLaunching(self):
        self.root=Tkinter.Tk()

_=App.sharedApplication()
AppHelper.runEventLoop()

产生以下异常:Python[23717:d07] -[App _setup:]: unrecognized selector sent to instance 0x105d05340

我在做什么错了?

推荐答案

我不认为您可以如此交替地混合使用Tkinter和Cocoa工具包. self.root是类App的属性，该类继承自AppKit.NSApplication.我的猜测是Tk()调用返回一个指针，该指针随后传递给Cocoa框架，但指向它无法理解的Tk数据结构.同样，Tkinter和PyObjC都需要自己的事件循环.我不确定您是否可以将两者混合使用(尽管我从未尝试过).

I don't think you can mix Tkinter and Cocoa toolkits so interchangeably. self.root is an attribute on the class App, which inherits from AppKit.NSApplication. My guess is that the Tk() call returns a pointer that is then passed to the Cocoa frameworks, but points to a Tk data structure that it can't understand. Also, both Tkinter and PyObjC need their own eventloop; I'm not sure if you can even mix the two (though I've never tried).

我的建议是使用一个或两个UI工具包，但不要同时使用两者.

My recommendation would be to use one UI toolkit or the other, but not both.
