使用wxpython进行双缓冲

import wx
import wx.lib.delayedresult as dr

class MyWindow(wx.Window):
    def __init__(self, parent):
        super().__init__(parent, style=wx.FULL_REPAINT_ON_RESIZE)
        self.Bind(wx.EVT_PAINT, self.OnPaint)

    def OnPaint(self, event):
        dc = wx.BufferedPaintDC(self)
        # 在这里绘制图像

def OnPaint(self, event):
    dc = wx.BufferedPaintDC(self)
    gc = wx.GraphicsContext.Create(dc)
    # 在这里绘制图像

def OnPaint(self, event):
    dc = wx.BufferedPaintDC(self)
    gc = wx.GraphicsContext.Create(dc)
    gc.SetBrush(wx.Brush('white'))
    gc.DrawRectangle(0, 0, self.GetSize().width, self.GetSize().height)
    # 在这里绘制图像

def OnPaint(self, event):
    dc = wx.BufferedPaintDC(self)
    gc = wx.GraphicsContext.Create(dc)
    gc.SetBrush(wx.Brush('white'))
    gc.DrawRectangle(0, 0, self.GetSize().width, self.GetSize().height)
    # 在这里绘制图像
    dc.DrawBitmap(bitmap, 0, 0)
