title: Control a hidden menu behind a button with pywinauto
body: <p>I'm very new to pywinauto ans I love it already. But I have a problem:</p>
  
  <p>I want to automate an old software program with pywinauto and can control most of the buttons. But there is a certain button when clicked, there appaers a menu with icons (not the windows style of menu but a custom menu). The button's name is "Toolbar2" so I guess it's not a normal button. 
  With this code I can click the button I want to. When I use "ctrl.Click(), the button doesn't get clicked, I need to use ClickInput(). With the normal buttons I do can use Click().</p>
  
  <pre><code>w_handle = pywinauto.findwindows.find_windows(title=u'P2-NLTlog013', class_name='TfrmDisplayFilteredData')[0]    
  window = pwa_app.window_(handle=w_handle)
  window.Click()
  ctrl = window['ToolBar2']
  ctrl.ClickInput()
  </code></pre>
  
  <p>My question now is: How can I get the names of the items of the hidden menu And click them. I already used this code, but then he gives a 'MatchError'.</p>
  
  <pre><code>window = pwa_app.Window_(best_match='ToolBar2', top_level_only=True).ChildWindow(best_match='PopupMenu').Click() 
  </code></pre>
  
  <p>window.Click()</p>
  
  <p>I don't know what language the software was written in...</p>
  
  <p>Thanks in advance,
  Fred</p>
