\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.

Appropriate 3D shading for the Windows 95 user interface is an option.

\begin{twocollist}\itemsep=0pt
\twocolitem{\windowstyle{wxSP\_3D}}{Draws a 3D effect border and sash.}
\twocolitem{\windowstyle{wxSP\_BORDER}}{Draws a thin black border around the window, and a black sash.}
\twocolitem{\windowstyle{wxSP\_NOBORDER}}{No border, and a black sash.}
\end{twocollist}

\membersection{wxSplitterWindow::wxSplitterWindow}\label{wxsplitterwindowconstr}

\func{}{wxSplitterWindow}{\void}

Default constructor.

\func{}{wxSplitterWindow}{\param{wxWindow*}{ parent}, \param{wxWindowID}{ id}, \param{int }{x},\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.

\helpref{wxSplitterWindow::SplitHorizontally}{wxsplitterwindowsplithorizontally}.

\membersection{wxSplitterWindow::IsSplit}\label{wxsplitterwindowissplit}

\constfunc{bool}{IsSplit}{\void}

Returns TRUE if the window is split, FALSE otherwise.

\membersection{wxSplitterWindow::OnDoubleClickSash}\label{wxsplitterwindowondoubleclicksash}

\func{virtual void}{OnDoubleClickSash}{\param{int }{x}, \param{int }{y}}

Application-overridable function called when the sash is double-clicked with
the left mouse button.

\wxheading{Parameters}

\docparam{x}{The x position of the mouse cursor.}

\docparam{y}{The y position of the mouse cursor.}

\wxheading{Remarks}

The default implementation of this function calls \helpref{Unsplit}{wxsplitterwindowunsplit} if
the minimum pane size is zero.

\wxheading{See also}

\helpref{wxSplitterWindow::Unsplit}{wxsplitterwindowunsplit}

\membersection{wxSplitterWindow::OnUnsplit}\label{wxsplitterwindowonunsplit}

\func{virtual void}{OnUnsplit}{\param{wxWindow* }{removed}}

Application-overridable function called when the window is unsplit, either
programmatically or using the wxSplitterWindow user interface.

\wxheading{Parameters}

\docparam{removed}{The window being removed.}

\wxheading{Remarks}

The default implementation of this function simply hides {\it removed}. You
may wish to delete the window.

\membersection{wxSplitterWindow::SetSashPosition}\label{wxsplitterwindowsetsashposition}

\func{void}{SetSashPosition}{\param{int }{position}, \param{const bool}{ redraw = TRUE}}

Sets the sash position.

\wxheading{Parameters}

\docparam{position}{The sash position in pixels.}

\docparam{redraw}{If TRUE, resizes the panes and redraws the sash and border.}

\wxheading{Remarks}

Does not currently check for an out-of-range value.

\helpref{wxSplitterWindow::GetSashPosition}{wxsplitterwindowgetsashposition}

\membersection{wxSplitterWindow::SetMinimumPaneSize}\label{wxsplitterwindowsetminimumpanesize}

\func{void}{SetMinimumPaneSize}{\param{int }{paneSize}}

Sets the minimum pane size.

\wxheading{Parameters}

\docparam{paneSize}{Minimum pane size in pixels.}

\wxheading{Remarks}

The default minimum pane size is zero, which means that either pane can be reduced to zero by dragging
the sash, thus removing one of the panes. To prevent this behaviour (and veto out-of-range sash dragging),
set a minimum size, for example 20 pixels.

\helpref{wxSplitterWindow::GetMinimumPaneSize}{wxsplitterwindowgetminimumpanesize}

\membersection{wxSplitterWindow::SetSplitMode}\label{wxsplitterwindowsetsplitmode}

\func{void}{SetSplitMode}{\param{int }{mode}}

Sets the split mode.

\wxheading{Parameters}

\docparam{mode}{Can be wxSPLIT\_VERTICAL or wxSPLIT\_HORIZONTAL.}

\wxheading{Remarks}

Only sets the internal variable; does not update the display.

\wxheading{See also}

\helpref{wxSplitterWindow::GetSplitMode}{wxsplitterwindowgetsplitmode}, \helpref{wxSplitterWindow::SplitVertically}{wxsplitterwindowsplitvertically},\rtfsp
\helpref{wxSplitterWindow::SplitHorizontally}{wxsplitterwindowsplithorizontally}.

\membersection{wxSplitterWindow::SplitHorizontally}\label{wxsplitterwindowsplithorizontally}

\func{bool}{SplitHorizontally}{\param{wxWindow* }{window1}, \param{wxWindow* }{window2},
 \param{int}{ sashPosition = -1}}

Initializes the top and bottom panes of the splitter window.

\wxheading{Parameters}

\docparam{window1}{The top pane.}

\docparam{window2}{The bottom pane.}

\docparam{sashPosition}{The initial position of the sash. If the value is -1, a default position
is chosen.}

\wxheading{Return value}

TRUE if successful, FALSE otherwise (the window was already split).

\wxheading{Remarks}

This should be called if you wish to initially view two panes. It can also be called at any subsequent time,
but the application should check that the window is not currently split using \helpref{IsSplit}{wxsplitterwindowissplit}.

\membersection{wxSplitterWindow::SplitVertically}\label{wxsplitterwindowsplitvertically}

\func{bool}{SplitVertically}{\param{wxWindow* }{window1}, \param{wxWindow* }{window2},
 \param{int}{ sashPosition = -1}}

Initializes the left and right panes of the splitter window.

\wxheading{Parameters}

\docparam{window1}{The left pane.}

\docparam{window2}{The right pane.}

\docparam{sashPosition}{The initial position of the sash. If the value is -1, a default position
is chosen.}

\wxheading{Return value}

TRUE if successful, FALSE otherwise (the window was already split).

\wxheading{Remarks}

\membersection{wxSplitterWindow::Unsplit}\label{wxsplitterwindowunsplit}

\func{bool}{Unsplit}{\param{wxWindow* }{toRemove = NULL}}

Unsplits the window.

\wxheading{Parameters}

\docparam{toRemove}{The pane to remove, or NULL to remove the right or bottom pane.}

\wxheading{Return value}

TRUE if successful, FALSE otherwise (the window was not split).

\wxheading{Remarks}

This call will not actually delete the pane being removed; it calls \helpref{OnUnsplit}{wxsplitterwindowonunsplit}\rtfsp
which can be overridden for the desired behaviour. By default, the pane being removed is hidden.
