显示另一个窗口 wxpython? [英] Show another window wxpython?

问题描述

我一直在浏览互联网，但我不确定是否有办法在 2 个单独的窗口中显示 wxPython 中的 2 个类.我们可以在它们之间进行交流吗(比如一个类是对话框，另一个类是主类)?

I have been looking around the Internet but I am not sure if there is a way to show 2 classes in wxPython in 2 separate windows. And could we communicate between them (like one class being the dialog and the other the main class)?

我想我是在使用 Show() 之前这样做的，但我不知道如何重复这个.

I think I did this before using Show() but I am not sure how to repeat this.

所以基本上我希望能够有一个对话框，但是通过使用一个类来代替.这将比使用模态对话框更强大.

So basically I would like to be able to have a dialog but by using a class instead. This would be more powerful than using Modal dialogs.

谢谢

推荐答案

这里有一个简单的两帧通信示例:

Here you have a simple example of two frames communicating:

诀窍是发送一个对象引用以在帧之间共享，要么在另一个内部创建一个(如本例中)，要么通过一个共同的父级.代码是:

The trick is in sending an object reference to share between frames, either creating one inside the other (as in this case) or through a common parent. The code is:

import wx

class MainFrame(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None, size=(150,100), title='MainFrame')
        pan =wx.Panel(self)
        self.txt = wx.TextCtrl(pan, -1, pos=(0,0), size=(100,20), style=wx.DEFAULT)
        self.but = wx.Button(pan,-1, pos=(10,30), label='Tell child')
        self.Bind(wx.EVT_BUTTON, self.onbutton, self.but)
        self.child = ChildFrame(self)
        self.child.Show()

    def onbutton(self, evt):
        text = self.txt.GetValue()
        self.child.txt.write('Parent says: %s' %text)


class ChildFrame(wx.Frame):
    def __init__(self, parent):
        wx.Frame.__init__(self, None, size=(150,100), title='ChildFrame')
        self.parent = parent
        pan = wx.Panel(self)
        self.txt = wx.TextCtrl(pan, -1, pos=(0,0), size=(100,20), style=wx.DEFAULT)
        self.but = wx.Button(pan,-1, pos=(10,30), label='Tell parent')
        self.Bind(wx.EVT_BUTTON, self.onbutton, self.but)

    def onbutton(self, evt):
        text = self.txt.GetValue()
        self.parent.txt.write('Child says: %s' %text)


if __name__ == "__main__":

    App=wx.PySimpleApp()
    MainFrame().Show()
    App.MainLoop()
