title: Using Python Tkinter: Always on top window isn't showing custom class tooltip text
body: <p>I can't get tooltip to work with my always on top window. Obviously the problem is you can't create something on top of something that's always on top; so i was wondering if there was a workaround or solution. The Popup needs to be always on top of other windows, but i also need to have all the tooltips show up properly.</p>
  
  <p>Here's a stripped down version of what I have so far:</p>
  
  <pre><code>from Tkinter import *
  
  class GUI:
      def __init__(self, root):
          Popup = Toplevel(root)
          Popup.resizable(0,0)
          Popup.attributes("-toolwindow", 1)
          Popup.wm_attributes("-topmost", 1)
          PFrame = Frame(Popup)
          self.B = Button(PFrame, width=10,height=10)
          self.B.pack()
          self.createToolTip(self.B,"Click this button.")
          PFrame.pack()
  
      class ToolTip(object):
          def __init__(self, widget):
              self.widget = widget
              self.tipwindow = None
              self.id = None
              self.x = self.y = 0
          def showtip(self, text):
              self.text = text
              if self.tipwindow or not self.text: return
              x,y,cx,cy = self.widget.bbox("insert")
              x = x + self.widget.winfo_rootx() +15
              y = y + cy + self.widget.winfo_rooty() +65
              self.tipwindow = tw = Toplevel(self.widget)
              tw.wm_overrideredirect(1)
              tw.wm_geometry("+%d+%d"%(x,y))
              label = Label(tw, text=self.text, justify=LEFT)
              label.pack(ipadx=1)
          def hidetip(self):
              tw = self.tipwindow
              self.tipwindow = None
              if tw: tw.destroy()
      def createToolTip(self,widget,text):
          toolTip = self.ToolTip(widget)
          def enter(event): self.tt = root.after(1500,show,event)
          def show(event): toolTip.showtip(text)
          def leave(event):
              if self.tt: root.after_cancel(self.tt)
              toolTip.hidetip()        
          widget.bind('&lt;Enter&gt;', enter)
          widget.bind('&lt;Leave&gt;', leave)
  
  if __name__ == '__main__':
      root = Tk()
      App = GUI(root)
      root.mainloop()
  </code></pre>
