只需使用一個wx.Panel
。
這裏是在繪圖方面功能的一些文檔:

import wx
class View(wx.Panel):
def __init__(self, parent):
super(View, self).__init__(parent)
self.SetBackgroundStyle(wx.BG_STYLE_CUSTOM)
self.Bind(wx.EVT_SIZE, self.on_size)
self.Bind(wx.EVT_PAINT, self.on_paint)
def on_size(self, event):
event.Skip()
self.Refresh()
def on_paint(self, event):
w, h = self.GetClientSize()
dc = wx.AutoBufferedPaintDC(self)
dc.Clear()
dc.DrawLine(0, 0, w, h)
dc.SetPen(wx.Pen(wx.BLACK, 5))
dc.DrawCircle(w/2, h/2, 100)
class Frame(wx.Frame):
def __init__(self):
super(Frame, self).__init__(None)
self.SetTitle('My Title')
self.SetClientSize((500, 500))
self.Center()
self.view = View(self)
def main():
app = wx.App(False)
frame = Frame()
frame.Show()
app.MainLoop()
if __name__ == '__main__':
main()
你如何處理這樣的 「畫布」 縮放? – Basj
嘗試'dc.SetUserScale' - http://www.wxpython.org/docs/api/wx.DC-class.html#SetUserScale – FogleBird
