.. class:: DocApp(wx.App)

   The DocApp class serves as the base class for pydocview applications and offers
   functionality such as services, creation of SDI and MDI frames, show tips,
   and a splash screen.

   .. method:: CloseChildDocuments(self, parentDocument)

      Closes the child windows of a Document.


   .. method:: CloseSplash(self)

      Closes the splash window.


   .. method:: CreateChildDocument(self, parentDocument, documentType, objectToEdit, path='')

      Creates a child window of a document that edits an object.  The child window
      is managed by the parent document frame, so it will be prompted to close if its
      parent is closed, etc.  Child Documents are useful when there are complicated
      Views of a Document and users will need to tunnel into the View.


   .. method:: CreateDocumentFrame(self, view, doc, flags, id = -1, title = "", pos = wx.DefaultPosition, size = wx.DefaultSize, style = wx.DEFAULT_FRAME_STYLE)

      Called by the DocManager to create and return a new Frame for a Document.
      Chooses whether to create an MDIChildFrame or SDI Frame based on the
      DocManager's flags.


   .. method:: CreateMDIDocumentFrame(self, doc, view, id=-1, title="", pos=wx.DefaultPosition, size=wx.DefaultSize, style=wx.DEFAULT_FRAME_STYLE)

      Creates and returns an MDI Document Frame.


   .. method:: CreateSDIDocumentFrame(self, doc, view, id=-1, title="", pos=wx.DefaultPosition, size=wx.DefaultSize, style=wx.DEFAULT_FRAME_STYLE)

      Creates and returns an SDI Document Frame.


   .. method:: CreateTabbedDocumentFrame(self, doc, view, id=-1, title="", pos=wx.DefaultPosition, size=wx.DefaultSize, style=wx.DEFAULT_FRAME_STYLE)

      Creates and returns an MDI Document Frame for a Tabbed MDI view


   .. method:: DoBackgroundListenAndLoad(self)

      Open any files specified in the given command line argument passed in via shared memory


   .. method:: GetDebug(self)

      Returns ``True`` if the application is in debug mode.


   .. method:: GetDefaultDocManagerFlags(self)

      Returns the default flags to use when creating the DocManager.


   .. method:: GetDefaultIcon(self)

   .. method:: GetDocumentManager(self)

      Returns the document manager associated to the DocApp.


   .. method:: GetEditMenu(self, frame)

      Utility method that finds the Edit menu within the menubar of a frame.


   .. method:: GetService(self, type)

      Returns the instance of a particular type of service that has been installed
      into the DocApp.  For example, "wx.GetApp().GetService(pydocview.OptionsService)"
      returns the isntance of the OptionsService that is running within the DocApp.


   .. method:: GetServices(self)

      Returns the DocService instances that have been installed into the DocApp.


   .. method:: GetSingleInstance(self)

      Returns ``True`` if the application is in single instance mode.  Used to determine if multiple instances of the application is allowed to launch.


   .. method:: GetUseTabbedMDI(self)

      Returns ``True`` if Windows MDI should use folder tabs instead of child windows.


   .. method:: InstallService(self, service)

      Installs an instance of a DocService into the DocApp.

      Returns ``True`` if the application is in MDI mode.


   .. method:: IsSDI(self)

      Returns ``True`` if the application is in SDI mode.


   .. method:: MacOpenFile(self, filename)


   .. method:: OnCloseChildWindow(self, event)

      Called when an MDI Child Frame is closed.  Calls SaveMDIDocumentFrameMaximizedState to
      remember whether the MDI Frame is maximized so that it can be restored on open.


   .. method:: OnCloseMainWindow(self, event)

      Called when the MDI Parent Frame is closed.  Remembers whether the MDI Parent Frame is
      maximized.

      Processes an event, searching event tables and calling zero or more
      suitable event handler function(s).  Note that the ProcessEvent

      process the window.


   .. method:: ProcessUpdateUIEvent(self, event)

      Enables services to process a UI event before the main window has a chance
      to process the window.


   .. method:: SaveMDIDocumentFrameMaximizedState(self, maximized)

      Remember in the config whether the MDI Frame is maximized so that it can be restored
      on open.


   .. method:: SetDebug(self, debug)

      Sets the application's debug mode.


   .. method:: SetDefaultIcon(self, icon)

      Sets the application's default icon.


   .. method:: SetDocumentManager(self, docManager)
