+\membersection{wxSplitterWindow::ReplaceWindow}\label{wxsplitterwindowreplacewindow}
+
+\func{bool}{ReplaceWindow}{\param{wxWindow * }{winOld}, \param{wxWindow * }{winNew}}
+
+This function replaces one of the windows managed by the wxSplitterWindow with
+another one. It is in general better to use it instead of calling Unsplit()
+and then resplitting the window back because it will provoke much less flicker
+(if any). It is valid to call this function whether the splitter has two
+windows or only one.
+
+Both parameters should be non-NULL and {\it winOld} must specify one of the
+windows managed by the splitter. If the parameters are incorrect or the window
+couldn't be replaced, false is returned. Otherwise the function will return
+true, but please notice that it will not delete the replaced window and you
+may wish to do it yourself.

+\membersection{wxSplitterWindow::SetSashGravity}\label{wxsplitterwindowsetsashgravity}

+Sets the sash gravity.
+
+\wxheading{Parameters}
+
+\docparam{gravity}{The sash gravity. Value between 0.0 and 1.0.}
+
+
+\wxheading{Remarks}
+Gravity is real factor which controls position of sash while resizing wxSplitterWindow.
+Gravity tells wxSplitterWindow how much will left/top window grow while resizing.
+
+Example values:
+\begin{itemize}\itemsep=0pt
+\item{ 0.0 - only the bottom/right window is automatically resized}
+\item{ 0.5 - both windows grow by equal size}
+\item{ 1.0 - only left/top window grows}
+\end{itemize}
+
+Gravity should be a real value between 0.0 and 1.0.
+
+Default value of sash gravity is 0.0. That value is compatible with previous
+(before gravity was introduced) behaviour of wxSplitterWindow.

+\func{void}{SetSashSize}{\param{int }{size}}
+
+Sets the sash size. Normally, the sash size is determined according to the metrics

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

Sets the minimum pane size.
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.

+\func{void}{UpdateSize}{\void}
+
+Causes any pending sizing of the sash and child panes to take place

+Such resizing normally takes place in idle time, in order
+to wait for layout to be completed. However, this can cause
+unacceptable flicker as the panes are resized after the window has been
+shown. To work around this, you can perform window layout (for
+example by sending a size event to the parent window), and then
+call this function, before showing the top-level window.
