wxPython popup fenêtre liée à un wxButton

Question

J'ai regardé autour, en parcourant un tas de différents sites et je suis incapable de trouver comment créer une popupwindow pour un wxButton dans wxPython.

Des idées comment?

Avez-vous regardé la démo de wxPython? Il a plusieurs exemples d'utilisation de wx.PopupWindow et de ses variantes. Voici un exemple basé sur la démo:

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()
