A classification of FL classes by category.

{\large {\bf Plugin classes}}

Plugins can be added to frame layouts to extend behaviour.

\twocolwidtha{6cm}
\begin{twocollist}\itemsep=0pt
\twocolitem{\helpref{cbAntiflickerPlugin}{cbantiflickerplugin}}{Double-buffering class}
\twocolitem{\helpref{cbBarDragPlugin}{cbbardragplugin}}{Implements drag behaviour.}
\twocolitem{\helpref{cbBarHintsPlugin}{cbbarhintsplugin}}{Implements bar decoration and sizing behaviour.}
\twocolitem{\helpref{cbHintAnimationPlugin}{cbhintanimationplugin}}{Draws animated hints when the user drags a pane.}
\twocolitem{\helpref{cbPaneDrawPlugin}{cbpanedrawplugin}}{Implements most of MFC-style control bar implementation.}
\twocolitem{\helpref{cbPluginBase}{cbpluginbase}}{Abstract base class for all control-bar related plugins.}

\twocolitem{\helpref{cbRowLayoutPlugin}{cbrowlayoutplugin}}{Implements row layout functionality.}
\twocolitem{\helpref{cbSimpleCustomizationPlugin}{cbsimplecustomizationplugin}}{Enables customization of a bar.}
\twocolitem{\helpref{cbBarSpy}{cbbarspy}}{Helper class used for spying for unhandled mouse events on control bars and forwarding them to the frame layout.}
\end{twocollist}

{\large {\bf Window classes}}

Windows classes (note that the mini-button implementations are not true windows
in that they do not derive from wxWindow).

\twocolwidtha{6cm}
\begin{twocollist}\itemsep=0pt
\twocolitem{\helpref{wxToolWindow}{wxtoolwindow}}{A small frame that paints its own titlebar.}
\twocolitem{\helpref{cbFloatedBarWindow}{cbfloatedbarwindow}}{A kind of wxToolWindow implementing floating windows.}
\twocolitem{\helpref{cbMiniButton}{cbminibutton}}{Base class for wxToolWindow titlebar buttons.}
\twocolitem{\helpref{cbCloseBox}{cbclosebox}}{Close button for wxToolWindow titlebar.}
\twocolitem{\helpref{cbCollapseBox}{cbcollapsebox}}{Collapse button for wxToolWindow titlebar.}
\twocolitem{\helpref{cbDockBox}{cbdockbox}}{Dock button for wxToolWindow titlebar.}

\twocolitem{\helpref{wxNewBitmapButton}{wxnewbitmapbutton}}{Alternative bitmap button class.}
\end{twocollist}

{\large {\bf Layout management classes}}

These classes relate to the layout management framework.

\twocolitem{\helpref{BagLayout}{baglayout}}{BagLayout lays out items in left-to-right order from top to bottom.}
\twocolitem{\helpref{cbUpdatesManagerBase}{cbupdatesmanagerbase}}{An abstract interface for display update optimization logic.}
\twocolitem{\helpref{cbSimpleUpdatesMgr}{cbsimpleupdatesmgr}}{Implements optimized logic for refreshing areas of frame layout that need to be updated.}
\twocolitem{\helpref{cbGCUpdatesMgr}{cbgcupdatesmgr}}{Implements optimized logic for refresh, based on a garbage collection algorithm.}
\twocolitem{\helpref{GarbageCollector}{garbagecollector}}{A garbage collection algorithm for use in display refresh optimization.}
\twocolitem{\helpref{wxFrameLayout}{wxframelayout}}{Manages containment and docking of control bars, which can be docked along the top, bottom, right, or left side of the parent frame.}
\end{twocollist}

{\large {\bf Event classes}}

Events are used to decouple parts of the layout framework. For event macros and identifiers,
please see the topic \helpref{Event macros and identifiers}{events}.
