   4
   5 This class manages up to two subwindows. The current view can be
   6 split into two programmatically (perhaps from a menu command), and unsplit
   7 either programmatically or via the wxSplitterWindow user interface.
   8
   9 Appropriate 3D shading for the Windows 95 user interface is an option.

  38
  39 Constructor for creating the window.
  40
  41 \wxheading{Parameters}

  52
  53 \docparam{name}{The window name.}
  54
  55 \wxheading{Remarks}
  56
  57 After using this constructor, you must create either one or two subwindows
  58 with the splitter window as parent, and then call one of \helpref{wxSplitterWindow::Initialize}{wxsplitterwindowinitialize},\rtfsp
  59 \helpref{wxSplitterWindow::SplitVertically}{wxsplitterwindowsplitvertically} and \helpref{wxSplitterWindow::SplitHorizontally}{wxsplitterwindowsplithorizontally} in
  60 order to set the pane(s).
  61
  62 You can create two windows, with one hidden when not being shown; or you can
  63 create and delete the second pane on demand.

 177
 178 \func{virtual void}{OnUnsplit}{\param{wxWindow* }{removed}}

 201
 202 \wxheading{Parameters}
 203
 204 \docparam{position}{The sash position in pixels.}

 217
 218 \func{void}{SetMinimumPaneSize}{\param{const int }{paneSize}}
 219
 220 Sets the minimum pane size.
 221
 222 \wxheading{Parameters}
 223
 224 \docparam{paneSize}{Minimum pane size in pixels.}
 225
 226 \wxheading{Remarks}
 227
 228 The default minimum pane size is zero, which means that either pane can be reduced to zero by dragging
 229 the sash, thus removing one of the panes. To prevent this behaviour (and veto out-of-range sash dragging),
 230 set a minimum size, for example 20 pixels.

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