\section{What is FL?}\label{whatisfl}
|
|
|
|
This manual describes FL (Frame Layout), a
|
|
class library for managing sophisticated window layout,
|
|
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}.
