Question

env：python37，windows，wxpython

在应用程序运行时有一个主框架保持打开状态，现在我正尝试在鼠标右键单击上创建一个新框架，如果我通过单击按钮打开它，但是如果它是由鼠标触发的，则该新框架会很好地工作click事件，它将挂起并且没有响应。我在想鼠标侦听器是否有问题，如果您有任何想法，请多谢。

这是代码详细信息：

import wx
import time
import win32api
from threading import Thread

class OtherFrame(wx.Frame):
    """
    Class used for creating frames other than the main one
    """

    def __init__(self, title, parent=None):
        wx.Frame.__init__(self, parent=parent, title=title)
        panel = wx.Panel(self)
        panel.SetBackgroundColour('yellow')
        self.Show()


class MyPanel(wx.Panel):

    def __init__(self, parent):
        wx.Panel.__init__(self, parent)

        btn = wx.Button(self, label='Create New Frame')
        btn.Bind(wx.EVT_BUTTON, self.on_new_frame)
        self.frame_number = 1

        thread = Thread(target=self.monitorMouse, name='monitorMouse')
        thread.daemon = True
        thread.start()

    def monitorMouse(self):
        state_left = win32api.GetKeyState(0x01)  # Left button down = 0 or 1. Button up = -127 or -128
        state_right = win32api.GetKeyState(0x02)  # Right button down = 0 or 1. Button up = -127 or -128

        while True:
            a = win32api.GetKeyState(0x01)
            b = win32api.GetKeyState(0x02)

            if b != state_right:  # Button state changed
                state_right = b
                if b < 0:
                    print('Right Button Pressed')
                else:
                    print('Right Button Released')
                    self.on_new_frame(None)
            time.sleep(0.001)

    def on_new_frame(self, event):
        title = 'SubFrame {}'.format(self.frame_number)
        frame = OtherFrame(title=title)
        self.frame_number += 1


class MainFrame(wx.Frame):

    def __init__(self):
        wx.Frame.__init__(self, None, title='Main Frame', size=(800, 600))
        panel = MyPanel(self)
        self.Show()


if __name__ == '__main__':
    app = wx.App(False)
    frame = MainFrame()
    app.MainLoop()

如果确定要使用线程监视鼠标，那么我认为您将不得不看看wx.lib.newevent.NewEvent()。
在线程中，您将使用wx.PostEvent将鼠标事件发送回主程序。

但是，wxpython已经为您提供了鼠标事件，您可以直接将其绑定到例如

import wx

class OtherFrame(wx.Frame):
    def __init__(self, title, parent=None):
        wx.Frame.__init__(self, parent=parent, title=title)
        panel = wx.Panel(self)
        panel.SetBackgroundColour('yellow')
        self.Show()

class MyPanel(wx.Panel):
    def __init__(self, parent):
        wx.Panel.__init__(self, parent)
        btn = wx.Button(self, label='Create New Frame')
        btn.Bind(wx.EVT_BUTTON, self.on_new_frame)
        self.Bind(wx.EVT_LEFT_DOWN, self.Left)
        self.Bind(wx.EVT_RIGHT_DOWN, self.Right)
        self.Bind(wx.EVT_RIGHT_DCLICK, self.on_new_frame)
        self.Bind(wx.EVT_CLOSE, self.Quit)
        self.frame_number = 1

    def Quit(self, event):
        self.Destroy()

    def Left(self, event):
        print("Left Button")
        event.Skip()

    def Right(self, event):
        print("Right Button")

    def on_new_frame(self, event):
        title = 'SubFrame {}'.format(self.frame_number)
        frame = OtherFrame(parent=self,title=title)
        self.frame_number += 1

class MainFrame(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None, title='Main Frame', size=(800, 600))
        panel = MyPanel(self)
        self.Show()

if __name__ == '__main__':
    app = wx.App(False)
    frame = MainFrame()
    app.MainLoop()

顺便说一句，注意这行

frame = OtherFrame(parent=self,title=title)

发送parent可以在关闭主框架时关闭所有未完成的OtherFrame's。

wxpython在鼠标上单击打开第二帧，无响应
