-\section{What is FL?}
+\section{What is FL?}\label{whatisfl}
This manual describes FL (Frame Layout), a
class library for managing sophisticated window layout,
-including docking panes.
+with panes that can be moved around the main window
+and customized. FL handles many decoration and dragging
+issues, giving applications the kind of docking facilities
+that Visual C++ and Netscape Navigator possess.
+
+FL was written by Aleksandras Gluchovas, and is heavily used in
+wxWorkshop which he also wrote the bulk of.
+
+{\bf Please note} that this guide is in its infancy, and contributions
+from FL users are very welcome.
+
+The following screenshot (from fl\_demo1) shows a frame with a number of
+bars that can be dragged around. The vertical grippers with
+two lines allow a bar to be dragged in that row, changing the
+ordering of the bar if necessary.
+The dotted grippers (as in Netscape Navigator) allow
+a whole row to be moved, again changing the position of the row
+if required. While moving a bar or row, immediate feedback
+is given as the moving bar displaces other bars.
+
+Other features: the splitter bar shows a dotted thick line as
+it's dragged. Single-clicking on a row handle minimizes it to
+a horizontal tab which is given its own narrow row. This allows
+the user to temporarily hide a row whilst allowing quick access
+to it when required.
+
+A close button (x) hides a bar completely. You can get it back again
+by right-clicking and selecting the appropriate menu item.
+
+A left, right, up or down arrow button expands the pane in that direction.

+\section{Compiling and using FL}
+
+FL can be found under the 'contrib' hierarchy, in the following directories:
+
+\begin{verbatim}
+ contrib/src/fl
+ contrib/include/wx/fl
+ contrib/samples/fl
+ contrib/docs/latex/fl
+ docs/html/fl
+ docs/htmlhelp/fl.chm
+ docs/pdf/fl.pdf
+ docs/winhelp/fl.hlp
+\end{verbatim}
+
+To compile FL:
+
+\begin{itemize}\itemsep=0pt
+\item Under Windows using VC++, open the flVC.dsw project
+and compile.
+\item Under Unix, FL should be configured when you configured
+wxWindows. Make FL by changing directory to contrib/src/fl and
+type 'make'. {\bf Note:} there is currently a
+problem with the wxWindows build system that means that
+only the static version of library can be built at present.
+\end{itemize}
+
+To use FL:
+
+\begin{itemize}\itemsep=0pt
+\item Under Windows using VC++, link with fl[d].lib.
+\item Under Unix, link with libfl[d].a.
+\end{itemize}
+
+\section{FL concepts}
+
+These are typical steps when adding FL functionality to your application.
+
+\begin{itemize}\itemsep=0pt
+\item include the appropriate header files;
+\item create a new \helpref{wxFrameLayout}{wxframelayout} passing the top-level frame and the window that
+is interpreted as the main 'client' window;
+\item set an updates manager for optimizing drag operations;
+\item add plugins for implementing various features;
+\item add bars;
+\item enable floating mode for the layout if required;
+\item delete the frame layout in the main frame's destructor.
+\end{itemize}
+
+The following is taken from fl\_demo1 and shows the main code implementing the
+user interface as illustrated in \helpref{What is FL?}{whatisfl}.

+\section{Controlling dragging behaviour}\label{controllingdragbehav}
+
+Various pane-dragging behaviours are supported. FL can
+show an outline of where the window would be docked
+if you stopped dragging at that point.
+
+This is a list of properties of interest in the cbCommonPaneProperties
+structure:
+
+\begin{verbatim}
+ bool mRealTimeUpdatesOn; // default: ON
+ bool mOutOfPaneDragOn; // default: ON
+ bool mExactDockPredictionOn; // default: OFF
+ bool mNonDestructFrictionOn; // default: OFF
+\end{verbatim}
+
+To get behaviour similar to Microsoft's DevStudio drag-ghost behaviour,
+mRealTimeUpdatesOn have to be set to FALSE, for example:
+
+\begin{verbatim}
+ cbCommonPaneProperties props;
+ ....
+ ....
+ props.mRealTimeUpdatesOn = FALSE;
+ fl->SetPaneProperties( props, wxALL_PANES );
+\end{verbatim}
+
+{\it mOutOfPaneDragOn} specifies whether bars can be dragged
+away from this pane. (Note: this may not currently be working.)
+
+{\it mExactDockPredictionOn} is only relevant when {\it mRealTimeUpdatesOn} is FALSE,
+and then the hint rectangle behaves a little jumpily. It tries to show
+exatly how the bar would look and where it would be docked if the dragging finished right
+now, i.e. the final position, with all the 'friction-physics' calculated.
+Otherwise the hint flies smothly above the surface only hinting whether the bar
+will be docked vertically or horizontally if dropped now.
+This is a feature you won't find anywhere else!
+
+{\it mNonDestructFirctionOn} causes the bars not being dragged
+to stay where they are, while the currently dragged one is 'diving'
+through the underlaying panes, docking itself in and out in real time.
+Otherwise the stationary bars would be pushed around messing up the composition permanently.
+This flag is irelevant when {\it mRealTimeUpdatesOn} is FALSE, as the ghost-rect
+does not do any docking until the drag finishes.
