Objective Grid: Using a CGXTabWnd in a static splitter window

Problem

How can I use a CGXTabWnd in a static splitter window?

Cause

Action

Here are the steps necessary for doing this:

Create a static splitter window class with ClassWizard, e.g. CScrltabsSplitMDIChildWnd
Next, call CreateStatic( ) in OnCreateClient( ) and create the windows (see the following sample code)
Finally, override PostNcDestroy() and delete the CGXTabWnd windows.

When you create the windows, you can create a tab window and embed the worksheets into it. The following example shows you how to display a static splitter window with two panes. The panes are CGXTabWnd, each having several worksheets.

Example:

class CScrltabsSplitMDIChildWnd : public CMDIChildWnd {
	DECLARE_DYNCREATE(CScrltabsSplitMDIChildWnd)
protected:
	// protected constructor used by dynamic creation CScrltabsSplitMDIChildWnd( );
public:
	// Attributes CSplitterWnd m_wndSplitter; CGXTabWnd* m_pTabWnd1; CGXTabWnd* m_pTabWnd2; // Operations BOOL OnCreateClient(LPCREATESTRUCT /lpcs/, CCreateContext* pContext); virtual void PostNcDestroy();
protected:
	// Implementation virtual ~CScrltabsSplitMDIChildWnd( ); // Generated message map functions //{{AFX_MSG(CScrltabsSplitMDIChildWnd) //}}AFX_MSG DECLARE_MESSAGE_MAP( )
}; BOOL CScrltabsSplitMDIChildWnd::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext) {
	CScrltabsApp* pApp = (CScrltabsApp*) AfxGetApp( ); // Specify the runtime class for the // first sheet. Don't forget to // register the document template // in InitInstance! pContext->m_pNewViewClass = RUNTIME_CLASS(CScrltabsFormView); m_wndSplitter.CreateStatic(this, 2, 1); // Creates the TabWnd object if (!m_wndSplitter.CreateView(0, 0, RUNTIME_CLASS(CGXTabWnd), CSize(0, (lpcs->cy / 2)), pContext)) {
		TRACE(Failed to create third pane ); return FALSE;
	} m_pTabWnd1 = (CGXTabWnd*) m_wndSplitter.GetPane(0, 0); // Creates the View2 worksheet in the tab window VERIFY(m_pTabWnd1->Create(this, View 1, pContext)); m_pTabWnd1->CreateView(RUNTIME_CLASS(CScrltabsView), View 2, pContext); // Creates the TabWnd object if (!m_wndSplitter.CreateView(1, 0, RUNTIME_CLASS(CGXTabWnd), CSize(0, (lpcs->cy / 2)), pContext)) {
		TRACE(Failed to create third pane ); return FALSE;
	} m_pTabWnd2 = (CGXTabWnd*) m_wndSplitter.GetPane(1, 0); // Creates the View1, View2 and View3 worksheets // in the tab window VERIFY(m_pTabWnd2->Create(this, View 1, pContext)); m_pTabWnd2->CreateView(RUNTIME_CLASS(CScrltabsView), View 2, pContext); m_pTabWnd2->CreateView(RUNTIME_CLASS(CScrltabsView), View 3, pContext); return TRUE;
} void CScrltabsSplitMDIChildWnd::PostNcDestroy() {
	// Tab windows must be deleted here delete m_pTabWnd1; m_pTabWnd1 = NULL; delete m_pTabWnd2; m_pTabWnd2 = NULL; CMDIChildWnd::PostNcDestroy();
}
