Example

### Example

The following fragment shows how to create a splitter window, creating two subwindows and hiding one of them.

      splitter = new wxSplitterWindow(this, -1, wxPoint(0, 0), wxSize(400, 400), wxSP_3D);

      leftWindow = new MyWindow(splitter);
      leftWindow->SetScrollbars(20, 20, 50, 50);

      rightWindow = new MyWindow(splitter);
      rightWindow->SetScrollbars(20, 20, 50, 50);
      rightWindow->Show(FALSE);

      splitter->Initialize(leftWindow);

      // Set this to prevent unsplitting
    //    splitter->SetMinimumPaneSize(20);

The next fragment shows how the splitter window can be manipulated after creation.

      void MyFrame::OnSplitVertical(wxCommandEvent& event)
      {
            if ( splitter->IsSplit() )
                splitter->Unsplit();
            leftWindow->Show(TRUE);
            rightWindow->Show(TRUE);
            splitter->SplitVertically( leftWindow, rightWindow );
      }

      void MyFrame::OnSplitHorizontal(wxCommandEvent& event)
      {
            if ( splitter->IsSplit() )
                splitter->Unsplit();
            leftWindow->Show(TRUE);
            rightWindow->Show(TRUE);
            splitter->SplitHorizontally( leftWindow, rightWindow );
      }

      void MyFrame::OnUnsplit(wxCommandEvent& event)
      {
            if ( splitter->IsSplit() )
                splitter->Unsplit();
      }
