+
+\wxheading{Parameters}
+
+\docparam{newSashPosition}{The new sash position (always positive or zero)}

+\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.

+
+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.
