如何在wx中制作自定义按钮？

这是一个骨架，您可以用来绘制完全自定义的按钮，其构想取决于它的外观或行为

class MyButton(wx.PyControl):    def __init__(self, parent, id, bmp, text, **kwargs):        wx.PyControl.__init__(self,parent, id, **kwargs)        self.Bind(wx.EVT_LEFT_DOWN, self._onMouseDown)        self.Bind(wx.EVT_LEFT_UP, self._onMouseUp)        self.Bind(wx.EVT_LEAVE_WINDOW, self._onMouseLeave)        self.Bind(wx.EVT_ENTER_WINDOW, self._onMouseEnter)        self.Bind(wx.EVT_ERASE_BACKGROUND,self._onEraseBackground)        self.Bind(wx.EVT_PAINT,self._onPaint)        self._mouseIn = self._mouseDown = False    def _onMouseEnter(self, event):        self._mouseIn = True    def _onMouseLeave(self, event):        self._mouseIn = False    def _onMouseDown(self, event):        self._mouseDown = True    def _onMouseUp(self, event):        self._mouseDown = False        self.sendButtonEvent()    def sendButtonEvent(self):        event = wx.CommandEvent(wx.wxEVT_COMMAND_BUTTON_CLICKED, self.GetId())        event.SetInt(0)        event.SetEventObject(self)        self.GetEventHandler().ProcessEvent(event)    def _onEraseBackground(self,event):        # reduce flicker        pass    def _onPaint(self, event):        dc = wx.BufferedPaintDC(self)        dc.SetFont(self.GetFont())        dc.SetBackground(wx.Brush(self.GetBackgroundColour()))        dc.Clear()        # draw whatever you want to draw        # draw glossy bitmaps e.g. dc.DrawBitmap        if self._mouseIn: pass# on mouserover may be draw different bitmap        if self._mouseDown: pass # draw different image text
