"The wx.aui moduleis an Advanced User Interface library that aims to
implement \"cutting-edge\" interface usability and design features so
developers can quickly and easily create beautiful and usable
application interfaces.

**Vision and Design Principles**

wx.aui attempts to encapsulate the following aspects of the user
interface:

  * Frame Management: Frame management provides the means to open,
    move and hide common controls that are needed to interact with the
    document, and allow these configurations to be saved into
    different perspectives and loaded at a later time.

  * Toolbars: Toolbars are a specialized subset of the frame
    management system and should behave similarly to other docked
    components. However, they also require additional functionality,
    such as \"spring-loaded\" rebar support, \"chevron\" buttons and
    end-user customizability.

  * Modeless Controls: Modeless controls expose a tool palette or set
    of options that float above the application content while allowing
    it to be accessed. Usually accessed by the toolbar, these controls
    disappear when an option is selected, but may also be \"torn off\"
    the toolbar into a floating frame of their own.

  * Look and Feel: Look and feel encompasses the way controls are
    drawn, both when shown statically as well as when they are being
    moved. This aspect of user interface design incorporates \"special
    effects\" such as transparent window dragging as well as frame
    animation.

**wx.aui adheres to the following principles**

  - Use native floating frames to obtain a native look and feel for
    all platforms;

  - Use existing wxPython code where possible, such as sizer
    implementation for frame management;

  - Use standard wxPython coding conventions.


**Usage**

The following example shows a simple implementation that utilizes
`wx.aui.FrameManager` to manage three text controls in a frame window::

    import wx
    import wx.aui

    class MyFrame(wx.Frame):

        def __init__(self, parent, id=-1, title='wx.aui Test',
                     size=(800, 600), style=wx.DEFAULT_FRAME_STYLE):
            wx.Frame.__init__(self, parent, id, title, pos, size, style)

            self._mgr = wx.aui.AuiManager(self)

            # create several text controls
            text1 = wx.TextCtrl(self, -1, 'Pane 1 - sample text',
                                wx.DefaultPosition, wx.Size(200,150),
                                wx.NO_BORDER | wx.TE_MULTILINE)

            text2 = wx.TextCtrl(self, -1, 'Pane 2 - sample text',
                                wx.DefaultPosition, wx.Size(200,150),
                                wx.NO_BORDER | wx.TE_MULTILINE)

            text3 = wx.TextCtrl(self, -1, 'Main content window',
                                wx.DefaultPosition, wx.Size(200,150),
                                wx.NO_BORDER | wx.TE_MULTILINE)

            # add the panes to the manager
            self._mgr.AddPane(text1, wx.LEFT, 'Pane Number One')
            self._mgr.AddPane(text2, wx.BOTTOM, 'Pane Number Two')
            self._mgr.AddPane(text3, wx.CENTER)

            # tell the manager to 'commit' all the changes just made
            self._mgr.Update()

            self.Bind(wx.EVT_CLOSE, self.OnClose)


        def OnClose(self, event):
            # deinitialize the frame manager
            self._mgr.UnInit()
            # delete the frame
            self.Destroy()


    app = wx.App()
    frame = MyFrame(None)
    frame.Show()
    app.MainLoop()

        GetPane is used to search for a `PaneInfo` object either by
        widget reference or by pane name, which acts as a unique id
        for a window pane. The returned `PaneInfo` object may then be
        modified to change a pane's look, state or position. After one
        or more modifications to the `PaneInfo`, `FrameManager.Update`
        should be called to realize the changes to the user interface.

        If the lookup failed (meaning the pane could not be found in
        the manager) GetPane returns an empty `PaneInfo`, a condition
        which can be checked by calling `PaneInfo.IsOk`.

        AddPane tells the frame manager to start managing a child

        verison accepts a `PaneInfo` object for the ``info`` parameter
        and allows the full spectrum of pane parameter
        possibilities. (Say that 3 times fast!)

        The second version is used for simpler user interfaces which
        do not require as much configuration.  In this case the
        ``info`` parameter specifies the direction property of the
        pane info, and defaults to ``wx.LEFT``.  The pane caption may
        also be specified as an extra parameter in this form.
