@class wxAuiManager
wxAuiManager is the central class of the wxAUI class framework.
wxAuiManager manages the panes associated with it for a particular wxFrame,
using a pane's wxAuiPaneInfo information to determine each pane's docking
and floating behavior.
wxAuiManager uses wxWidgets' sizer mechanism to plan the layout of each
frame. It uses a replaceable dock art class to do all drawing, so all
drawing is localized in one area, and may be customized depending on an
application's specific needs.
wxAuiManager works as follows: the programmer adds panes to the class,
or makes changes to existing pane properties (dock position, floating
state, show state, etc.). To apply these changes, wxAuiManager's
Update() function is called. This batch processing can be used to avoid
flicker, by modifying more than one pane at a time, and then "committing"
all of the changes at once by calling Update().
Panes can be added quite easily:
@code
wxTextCtrl* text1 = new wxTextCtrl(this, -1);
wxTextCtrl* text2 = new wxTextCtrl(this, -1);
m_mgr.AddPane(text1, wxLEFT, "Pane Caption");
m_mgr.AddPane(text2, wxBOTTOM, "Pane Caption");
m_mgr.Update();
@endcode
Later on, the positions can be modified easily. The following will float
an existing pane in a tool window:
@code
m_mgr.GetPane(text1).Float();
@endcode
@section auimanager_layers Layers, Rows and Directions, Positions
Inside wxAUI, the docking layout is figured out by checking several pane
parameters. Four of these are important for determining where a pane will
end up:
@li Direction: Each docked pane has a direction, Top, Bottom, Left, Right,
or Center. This is fairly self-explanatory. The pane will be placed in
the location specified by this variable.
@li Position: More than one pane can be placed inside of a dock. Imagine
two panes being docked on the left side of a window. One pane can be
placed over another. In proportionally managed docks, the pane
position indicates its sequential position, starting with zero. So, in
our scenario with two panes docked on the left side, the top pane in
the dock would have position 0, and the second one would occupy
position 1.
@li Row: A row can allow for two docks to be placed next to each other.
One of the most common places for this to happen is in the toolbar.
Multiple toolbar rows are allowed, the first row being row 0, and the
second row 1. Rows can also be used on vertically docked panes.
@li Layer: A layer is akin to an onion. Layer 0 is the very center of the
managed pane. Thus, if a pane is in layer 0, it will be closest to the
center window (also sometimes known as the "content window").
Increasing layers "swallow up" all layers of a lower value. This can
look very similar to multiple rows, but is different because all panes
in a lower level yield to panes in higher levels. The best way to
understand layers is by running the wxAUI sample.
@beginEventTable{wxAuiManagerEvent}
@event{EVT_AUI_PANE_BUTTON(func)}
Triggered when any button is pressed for any docked panes.
@event{EVT_AUI_PANE_CLOSE(func)}
Triggered when a docked or floating pane is closed.
@event{EVT_AUI_PANE_MAXIMIZE(func)}
Triggered when a pane is maximized.
@event{EVT_AUI_PANE_RESTORE(func)}
Triggered when a pane is restored.
@event{EVT_AUI_RENDER(func)}
This event can be caught to override the default renderer in order to
custom draw your wxAuiManager window (not recommended).
