wxPython：面板一部分上的 EVT_BUTTON

你好 evryone :) 我想在 wx.Panel 内绘制的蓝色框中捕获单击事件

我已经知道如何对按钮单击做出反应：

myButton.Bind(wx.EVT_BUTTON, myHandler)

或者

myFrame.Bind(wx.EVT_BUTTON, myHandler, myFrame.myConcernedButton)

但是如果我想

在面板上绘制一个蓝色方块，我该怎么做，什么幸运的是，我已经可以应付了。
仅将 EVT_BUTTON 捕获到蓝色方块上，而不是整个面板上？

我想我应该为我的 SquareBox 创建一个新类，但是：

它应该从哪个类派生？
到目前为止，如何向该类添加事件处理？

非常感谢。

PS：对于很少的历史，我曾经使用 Java 和 Java 进行开发。 SWING

编辑：

正如 Mike Driscoll 所建议的那样，我尝试使用 PlateButton 来解决我的问题。但不幸的是，我没有设法为按钮提供所需的尺寸或所需的样式（单击时它会改变颜色，我不希望这样）。此外，它对 EVT_BUTTON 事件根本没有反应。

这是我的尝试，提前致谢：

import wx
from wx.lib.platebtn import PlateButton

class Square(PlateButton):

    def __init__(self, parent, size, pos):
        PlateButton.__init__(self, parent, size = size, pos = pos)
        self.SetBackgroundColour(wx.Colour(0,0,255))

class MainFrame(wx.Frame):

    def __init__(self):
        wx.Frame.__init__(self, None, wx.ID_ANY, "Reactive square application",
            size = (300,200))
        panel = wx.Panel(self, wx.ID_ANY)
        square1 = Square(panel, size=(60,60), pos=(80,50))
        square2 = Square(panel, size=(60,60), pos=(80,120))
        square1.Bind(wx.EVT_BUTTON, self.OnSquareClick)

    def OnSquareClick(self, event):
        dialog = wx.MessageDialog(self, "You clicked on square !!!",
            "Hit has been done", wx.OK)
        dialog.Show(True)


if __name__ == "__main__":
    app = wx.PySimpleApp()
    frame = MainFrame()
    frame.Show(True)
    app.MainLoop()

Hello evryone :) I would like to capture click event in a blue box drawn inside a wx.Panel

I already know how to reacts to button click :

myButton.Bind(wx.EVT_BUTTON, myHandler)

myFrame.Bind(wx.EVT_BUTTON, myHandler, myFrame.myConcernedButton)

But how must I do if I want to

Draw a blue square onto a Panel, what I can already manage, luckily.
Capture a EVT_BUTTON onto the blue square only, and not the whole panel ?

I think I should make a new class for my SquareBox, but :

What class should it be derived from ?
So far then, how to add event handling to that class ?

Thank you very much.

P.S : For the little history, I used to develop in Java & SWING

Edit :

As Mike Driscoll advised me, I tried to solve my problem with a PlateButton. But unfortunately, I did not managed to give the button the wanted dimension nor the wanted style (it changes its color when it is clicked, and I don't wan't this). Furthermore, it doesn't react at all to EVT_BUTTON event.

This is my attempt, thanks in advance :

import wx
from wx.lib.platebtn import PlateButton

class Square(PlateButton):

    def __init__(self, parent, size, pos):
        PlateButton.__init__(self, parent, size = size, pos = pos)
        self.SetBackgroundColour(wx.Colour(0,0,255))

class MainFrame(wx.Frame):

    def __init__(self):
        wx.Frame.__init__(self, None, wx.ID_ANY, "Reactive square application",
            size = (300,200))
        panel = wx.Panel(self, wx.ID_ANY)
        square1 = Square(panel, size=(60,60), pos=(80,50))
        square2 = Square(panel, size=(60,60), pos=(80,120))
        square1.Bind(wx.EVT_BUTTON, self.OnSquareClick)

    def OnSquareClick(self, event):
        dialog = wx.MessageDialog(self, "You clicked on square !!!",
            "Hit has been done", wx.OK)
        dialog.Show(True)


if __name__ == "__main__":
    app = wx.PySimpleApp()
    frame = MainFrame()
    frame.Show(True)
    app.MainLoop()
