wxPython woes -- docs, PopupMenus

[jrcagle]

So it's like this: I want to create an 'activebutton' widget with the following properties.

* The button itself is text that changes foreground color when the mouse hovers over it.
* If the mouse hovers for more than 200ms, a PopupMenu appears that allows the user to select a subitem corresponding to the button.

That is, if the button says "file", the PopupMenu might say "New", "Save", etc.

* If the user moves off the PopupMenu, it goes away.

Unfortunately, I can't manage the last one. And, documentation for PopupMenu's seems to be scarce on the 'Net. I'm relying mostly on http://www.wxpython.org/onlinedocs.php, but there are at least two classes (wx.PopupWindow, wx.PopupTransientWindow) that I can't find there, AND the help(...) files are remarkably verbose, yet sparse on useful detail. Grrr....

Any thoughts greatly appreciated.

import wx

class ActiveButton(wx.StaticText):

    def __init__(self, parent, id=wx.ID_ANY, label="An ActiveButton",
                 pos=wx.DefaultPosition,size=wx.DefaultSize,style=0):
        wx.StaticText.__init__(self, parent=parent, id=id, label=label,
                               pos=pos,size=size,style=style)
        self.SetForegroundColour(wx.Color(255,0,0))
        self.Bind(wx.EVT_ENTER_WINDOW,self.OnEnter)
        self.Bind(wx.EVT_LEAVE_WINDOW,self.OnLeave)
        self.timer = wx.Timer(self, id=1)
        self.Bind(wx.EVT_TIMER, self.CreateMenu)
        self.menu=wx.Menu()

    def OnEnter(self, event):
        if not self.timer.IsRunning():
            self.timer.Start(200,oneShot=True)
        self.SetForegroundColour(wx.Color(0,255,0)) # delightful color scheme
        self.Refresh()

    def OnLeave(self,event):
        self.SetForegroundColour(wx.Color(255,0,0))
        self.Refresh()
        self.timer.Stop()
        # should also dismiss PopupMenu

    def CreateMenu(self, event):
        m = self.PopupMenu(self.menu,(-65,0))
        print m  # prints True or False!
        
    def AddItem(self,text,id=None,handler=None):
        if id == None:
            id = wx.NewId()
        self.menu.Append(id,text)
        wx.EVT_MENU(self.menu,id,handler)
