wxPython彈出窗口綁定到wxButton

Question

我一直在環顧四周，瀏覽一大堆不同的網站，我無法找到如何在wxPython中爲wxButton創建一個popupwindow。

任何想法如何？

你看過wxPython演示了嗎？它有幾個使用wx.PopupWindow及其變體的例子。這裏是一個基於演示的例子：

import wx 

######################################################################## 
class TestPopup(wx.PopupWindow): 
    """""" 

    #---------------------------------------------------------------------- 
    def __init__(self, parent, style): 
     """Constructor""" 
     wx.PopupWindow.__init__(self, parent, style) 

     panel = wx.Panel(self) 
     self.panel = panel 
     panel.SetBackgroundColour("CADET BLUE") 

     st = wx.StaticText(panel, -1, 
          "This is a special kind of top level\n" 
          "window that can be used for\n" 
          "popup menus, combobox popups\n" 
          "and such.\n\n" 
          "Try positioning the demo near\n" 
          "the bottom of the screen and \n" 
          "hit the button again.\n\n" 
          "In this demo this window can\n" 
          "be dragged with the left button\n" 
          "and closed with the right." 
          , 
          pos=(10,10)) 
     sz = st.GetBestSize() 
     self.SetSize((sz.width+20, sz.height+20)) 
     panel.SetSize((sz.width+20, sz.height+20)) 

     panel.Bind(wx.EVT_LEFT_DOWN, self.OnMouseLeftDown) 
     panel.Bind(wx.EVT_MOTION, self.OnMouseMotion) 
     panel.Bind(wx.EVT_LEFT_UP, self.OnMouseLeftUp) 
     panel.Bind(wx.EVT_RIGHT_UP, self.OnRightUp) 

     st.Bind(wx.EVT_LEFT_DOWN, self.OnMouseLeftDown) 
     st.Bind(wx.EVT_MOTION, self.OnMouseMotion) 
     st.Bind(wx.EVT_LEFT_UP, self.OnMouseLeftUp) 
     st.Bind(wx.EVT_RIGHT_UP, self.OnRightUp) 

     wx.CallAfter(self.Refresh)  

    def OnMouseLeftDown(self, evt): 
     self.Refresh() 
     self.ldPos = evt.GetEventObject().ClientToScreen(evt.GetPosition()) 
     self.wPos = self.ClientToScreen((0,0)) 
     self.panel.CaptureMouse() 

    def OnMouseMotion(self, evt): 
     if evt.Dragging() and evt.LeftIsDown(): 
      dPos = evt.GetEventObject().ClientToScreen(evt.GetPosition()) 
      nPos = (self.wPos.x + (dPos.x - self.ldPos.x), 
        self.wPos.y + (dPos.y - self.ldPos.y)) 
      self.Move(nPos) 

    def OnMouseLeftUp(self, evt): 
     if self.panel.HasCapture(): 
      self.panel.ReleaseMouse() 

    def OnRightUp(self, evt): 
     self.Show(False) 
     self.Destroy()
