\section{\class{wxSplitterWindow}}\label{wxsplitterwindow}

\overview{wxSplitterWindow overview}{wxsplitterwindowoverview}

This class manages up to two subwindows. The current view can be
split into two programmatically (perhaps from a menu command), and unsplit
either programmatically or via the wxSplitterWindow user interface.

\wxheading{Window styles}

\begin{twocollist}\itemsep=0pt
\twocolitem{\windowstyle{wxSP\_3D}}{Draws a 3D effect border and sash.}
\twocolitem{\windowstyle{wxSP\_3DSASH}}{Draws a 3D effect sash.}
\twocolitem{\windowstyle{wxSP\_3DBORDER}}{Synonym for wxSP\_BORDER.}
\twocolitem{\windowstyle{wxSP\_BORDER}}{Draws a standard border.}
\twocolitem{\windowstyle{wxSP\_NOBORDER}}{No border (default).}
\twocolitem{\windowstyle{wxSP\_NO\_XP\_THEME}}{Under Windows XP, switches off the attempt to draw the
splitter using Windows XP theming, so the borders and sash will take on the pre-XP look.}
\twocolitem{\windowstyle{wxSP\_PERMIT\_UNSPLIT}}{Always allow to
unsplit, even with the minimum pane size other than zero.}
\twocolitem{\windowstyle{wxSP\_LIVE\_UPDATE}}{Don't draw XOR line but resize the child windows immediately.}

\wxheading{Event handling}

To process input from a splitter control, use the following event handler
macros to direct input to member functions that take a 
\helpref{wxSplitterEvent}{wxsplitterevent} argument.

\twocolwidtha{10cm}
\begin{twocollist}\itemsep=0pt
\twocolitem{{\bf EVT\_SPLITTER\_SASH\_POS\_CHANGING(id, func)}}{The sash
position is in the process of being changed. May be used to modify the
position of the tracking bar to properly reflect the position that
would be set if the drag were to be completed at this point. Processes
a wxEVT\_COMMAND\_SPLITTER\_SASH\_POS\_CHANGING event.}
\twocolitem{{\bf EVT\_SPLITTER\_SASH\_POS\_CHANGED(id, func)}}{The sash
position was changed. May be used to modify the sash position before
it is set, or to prevent the change from taking place.
Processes a wxEVT\_COMMAND\_SPLITTER\_SASH\_POS\_CHANGED event.}
\twocolitem{{\bf EVT\_SPLITTER\_UNSPLIT(id, func)}}{The splitter has been just
unsplit. Processes a wxEVT\_COMMAND\_SPLITTER\_UNSPLIT event.}
\twocolitem{{\bf EVT\_SPLITTER\_DCLICK(id, func)}}{The sash was double
clicked. The default behaviour is to unsplit the window when this happens
(unless the minimum pane size has been set to a value greater than zero).
Processes a wxEVT\_COMMAND\_SPLITTER\_DOUBLECLICKED event.}

\membersection{wxSplitterWindow::wxSplitterWindow}\label{wxsplitterwindowctor}

\func{}{wxSplitterWindow}{\void}

Default constructor.

\func{}{wxSplitterWindow}{\param{wxWindow*}{ parent}, \param{wxWindowID}{ id},\rtfsp
\param{const wxPoint\& }{point = wxDefaultPosition}, \param{const wxSize\& }{size = wxDefaultSize},\rtfsp
\param{long }{style=wxSP\_3D}, \param{const wxString\&}{ name = "splitterWindow"}}

Constructor for creating the window.

\wxheading{Parameters}

\docparam{parent}{The parent of the splitter window.}

\docparam{id}{The window identifier.}

\docparam{pos}{The window position.}

\docparam{size}{The window size.}

\docparam{style}{The window style. See \helpref{wxSplitterWindow}{wxsplitterwindow}.}

\docparam{name}{The window name.}

\wxheading{Remarks}

After using this constructor, you must create either one or two subwindows
with the splitter window as parent, and then call one of \helpref{wxSplitterWindow::Initialize}{wxsplitterwindowinitialize},\rtfsp
\helpref{wxSplitterWindow::SplitVertically}{wxsplitterwindowsplitvertically} and \helpref{wxSplitterWindow::SplitHorizontally}{wxsplitterwindowsplithorizontally} in
order to set the pane(s).

You can create two windows, with one hidden when not being shown; or you can
create and delete the second pane on demand.

\membersection{wxSplitterWindow::\destruct{wxSplitterWindow}}\label{wxsplitterwindowdtor}

\func{}{\destruct{wxSplitterWindow}}{\void}

Destroys the wxSplitterWindow and its children.

\membersection{wxSplitterWindow::Create}\label{wxsplitterwindowcreate}

\func{bool}{Create}{\param{wxWindow*}{ parent}, \param{wxWindowID}{ id}, \rtfsp
\param{const wxPoint\& }{point = wxDefaultPosition}, \param{const wxSize\& }{size = wxDefaultSize},\rtfsp
\param{long }{style=wxSP\_3D}, \param{const wxString\&}{ name = "splitterWindow"}}

Creation function, for two-step construction. See \helpref{wxSplitterWindow::wxSplitterWindow}{wxsplitterwindowctor} for
details.

\membersection{wxSplitterWindow::GetMinimumPaneSize}\label{wxsplitterwindowgetminimumpanesize}

\constfunc{int}{GetMinimumPaneSize}{\void}

Returns the current minimum pane size (defaults to zero).

\membersection{wxSplitterWindow::GetSashGravity}\label{wxsplitterwindowgetsashgravity}

\func{double}{GetSashGravity}{\void}

Returns the current sash gravity.

\membersection{wxSplitterWindow::Initialize}\label{wxsplitterwindowinitialize}

\func{void}{Initialize}{\param{wxWindow* }{window}}

Initializes the splitter window to have one pane.  The child window is
shown if it is currently hidden.

\wxheading{Parameters}

\docparam{window}{The pane for the unsplit window.}

\wxheading{Remarks}

This should be called if you wish to initially view only a single pane in the splitter window.
