\section{\class{wxFrameLayout}}\label{wxframelayout}

which can be docked along the top, bottom, right, or left side of the
parent frame.

\membersection{wxFrameLayout::wxFrameLayout}\label{wxframelayoutwxframelayout}

\func{}{wxFrameLayout}{\param{wxWindow* }{pParentFrame}, \param{wxWindow* }{pFrameClient = NULL}, \param{bool }{activateNow = TRUE}}

Constructor, taking parent window, the (MDI) client of the parent if there
is one, and flag specifying whether to activate the layout.


\func{}{wxFrameLayout}{\void}

Default constructor, used only for serialization.


\membersection{wxFrameLayout::\destruct{wxFrameLayout}}\label{wxframelayoutdtor}

\func{}{\destruct{wxFrameLayout}}{\void}

Destructor. It does not destroy the bar windows.


\membersection{wxFrameLayout::Activate}\label{wxframelayoutactivate}

\func{void}{Activate}{\void}

Activate can be called after some other layout has been deactivated,
and this one must take over the current contents of the frame window.
Effectively hooks itself to the frame window, re-displays all non-hidden
bar windows and repaints the decorations.


\membersection{wxFrameLayout::AddBar}\label{wxframelayoutaddbar}

\func{void}{AddBar}{\param{wxWindow* }{pBarWnd}, \param{const cbDimInfo\& }{dimInfo}, \param{int }{alignment = FL\_ALIGN\_TOP}, \param{int }{rowNo = 0}, \param{int }{columnPos = 0}, \param{const wxString\& }{name = "bar"}, \param{bool }{spyEvents = FALSE}, \param{int }{state = wxCBAR\_DOCKED\_HORIZONTALLY}}

Adds bar information to the frame layout. The appearance of the layout is not refreshed
immediately; RefreshNow() can be called if necessary.
Notes: the argument pBarWnd can by NULL, resulting in bar decorations to be drawn
around the empty rectangle (filled with default background colour).
Argument dimInfo can be reused for adding any number of bars, since
it is not used directly - instead its members are copied. If the dimensions
handler is present, its instance is shared (reference counted). The dimension
handler should always be allocated on the heap.
pBarWnd is the window to be managed.
dimInfo contains dimension information.
alignment is a value such as FL\_ALIGN\_TOP.
rowNo is the vertical position or row in the pane (if in docked state).
columnPos is the horizontal position within the row in pixels (if in docked state).
name is a name by which the bar can be referred in layout customization dialogs.
If spyEvents is TRUE, input events for the bar should be "spyed" in order
to forward unhandled mouse clicks to the frame layout, for example to enable
easy draggablity of toolbars just by clicking on their interior regions.
For widgets like text/tree control this value should be FALSE,
since there's no certain way to detect  whether the event was actually handled.
state is the initial state, such as wxCBAR\_DOCKED\_HORIZONTALLY,
wxCBAR\_FLOATING, wxCBAR\_HIDDEN.


\membersection{wxFrameLayout::AddPlugin}\label{wxframelayoutaddplugin}

\func{void}{AddPlugin}{\param{wxClassInfo* }{pPlInfo}, \param{int }{paneMask = wxALL\_PANES}}

An advanced methods for plugin configuration    using their
dynamic class information, for example CLASSINFO(pluginClass).
First checks if the plugin of the given class is already "hooked up".
If not, adds it to the top of the plugins chain.


\membersection{wxFrameLayout::AddPluginBefore}\label{wxframelayoutaddpluginbefore}

\func{void}{AddPluginBefore}{\param{wxClassInfo* }{pNextPlInfo}, \param{wxClassInfo* }{pPlInfo}, \param{int }{paneMask = wxALL\_PANES}}

First checks if the plugin of the given class is already hooked.
If so, removes it, and then inserts it into the chain
before the plugin of the class given by pNextPlInfo.
Note: this method is handy in some cases where the order
of the plugin-chain could be important, for example when one plugin overrides
some functionality of another already-hooked plugin,
so that the former plugin should be hooked before the one
whose functionality is being overridden.


\membersection{wxFrameLayout::ApplyBarProperties}\label{wxframelayoutapplybarproperties}

\func{void}{ApplyBarProperties}{\param{cbBarInfo* }{pBar}}

Reflects changes in bar information structure visually.
For example, moves the bar, changes its dimension information,
or changes the pane to which it is docked.


\membersection{wxFrameLayout::CanReparent}\label{wxframelayoutcanreparent}

\func{bool}{CanReparent}{\void}

Returns TRUE if the platform allows reparenting. This may not return TRUE
for all platforms. Reparenting allows control bars to be floated.


\membersection{wxFrameLayout::CaptureEventsForPane}\label{wxframelayoutcaptureeventsforpane}

\func{void}{CaptureEventsForPane}{\param{cbDockPane* }{toPane}}

Called by plugins; also captures the mouse in the parent frame.

\membersection{wxFrameLayout::Deactivate}\label{wxframelayoutdeactivate}

\func{void}{Deactivate}{\void}

Deactivate unhooks itself from frame window, and hides all non-hidden windows.

same frame window, since it would cause messy overlapping of bar windows
from both layouts.

\membersection{wxFrameLayout::FirePluginEvent}\label{wxframelayoutfirepluginevent}

\func{void}{FirePluginEvent}{\param{cbPluginEvent\& }{event}}

This function should be used instead of passing the event to the ProcessEvent method
of the top-level plugin directly. This method checks if events are currently
captured and ensures that plugin-event is routed correctly.

cbAntiflickerPlugin, cbSimpleCustomizePlugin.
This method is automatically invoked if no plugins were found upon
firing of the first plugin-event, i.e. when wxFrameLayout configures itself.

from the pane it currently belongs to, and inserted into the pane, which "matches"
the given rectangular area. If pToPane is not NULL, the bar is docked to this given pane.
To dock a bar which is floating, use the wxFrameLayout::DockBar method.

Removes the bar from the layout permanently, and hides its corresponding window if present.


\membersection{wxFrameLayout::RemovePlugin}\label{wxframelayoutremoveplugin}

\func{void}{RemovePlugin}{\param{wxClassInfo* }{pPlInfo}}

it if found.


\membersection{wxFrameLayout::ReparentWindow}\label{wxframelayoutreparentwindow}

\func{void}{ReparentWindow}{\param{wxWindow* }{pChild}, \param{wxWindow* }{pNewParent}}

Reparents pChild to have parent pNewParent.


\membersection{wxFrameLayout::RepositionFloatedBar}\label{wxframelayoutrepositionfloatedbar}

Applies the calculated layout to a floating bar.


\membersection{wxFrameLayout::RouteMouseEvent}\label{wxframelayoutroutemouseevent}

\func{void}{RouteMouseEvent}{\param{wxMouseEvent\& }{event}, \param{int }{pluginEvtType}}

Routes the mouse event to the appropriate pane.


\membersection{wxFrameLayout::SetBarState}\label{wxframelayoutsetbarstate}

\func{void}{SetBarState}{\param{cbBarInfo* }{pBar}, \param{int }{newStatem}, \param{bool }{updateNow}}

Changes the bar's docking state (see possible control bar states).


\membersection{wxFrameLayout::SetFrameClient}\label{wxframelayoutsetframeclient}

\func{void}{SetFrameClient}{\param{wxWindow* }{pFrameClient}}

Passes the client window (e.g. MDI client window) to be controlled by
frame layout, the size and position of which should be adjusted to be
surrounded by controlbar panes, whenever the frame is resized or the dimensions
of control panes change.


\membersection{wxFrameLayout::SetMargins}\label{wxframelayoutsetmargins}

\func{void}{SetMargins}{\param{int }{top}, \param{int }{bottom}, \param{int }{left}, \param{int }{right}, \param{int }{paneMask = wxALL\_PANES}}

The margins should go into cbCommonPaneProperties in the future.
Note: this method should be called before any custom plugins are attached.


\membersection{wxFrameLayout::SetPaneBackground}\label{wxframelayoutsetpanebackground}

\func{void}{SetPaneBackground}{\param{const wxColour\& }{colour}}

Sets the pane background colour.


\membersection{wxFrameLayout::SetPaneProperties}\label{wxframelayoutsetpaneproperties}

\func{void}{SetPaneProperties}{\param{const cbCommonPaneProperties\& }{props}, \param{int }{paneMask = wxALL\_PANES}}

Sets the pane properties for the given alignment.

\membersection{wxFrameLayout::SetTopPlugin}\label{wxframelayoutsettopplugin}

\func{void}{SetTopPlugin}{\param{cbPluginBase* }{pPlugin}}

Hooking custom plugins to frame layout.
Note: when hooking one plugin on top of the other,
use SetNextHandler or similar methods
of wxEvtHandler class to compose the chain of plugins,
than pass the left-most handler in this chain to
the above methods (assuming that events are delegated
from left-most towards right-most handler).
This secenario is very inconvenient and "low-level",
so use the Add/Push/PopPlugin methods instead.


\membersection{wxFrameLayout::SetUpdatesManager}\label{wxframelayoutsetupdatesmanager}

\func{void}{SetUpdatesManager}{\param{cbUpdatesManagerBase* }{pUMgr}}

Destroys the previous manager if any, and sets the new one.
