Introduction

I needed a 3 window splitter that will split the window in a "T" shape as opposed to 3 columns or 3 rows. This CExSplitter3Wnd class will allow you to create a 3 window splitter according to a pre-defined layout. Below are the patterns that are defined. Note that you can add any layout you wish:

Note that PATTERN_5 and PATTERN_6 are created the usual way. The other 4 patterns show the extended style.

To create one of those patterns:

1. Override the OnCreateClient function in your SDI MainFrame.
2. Construct a new CExSplitter3Wnd object
3. Set style and initial view sizes
4. Call the set pattern function with the following parameters :
   • CWnd* pParent
   • SPLIT_PATTERN SplitPattern
   • CRuntimeClass* pFirstView
   • CRuntimeClass* pSecView
   • CRuntimeClass* pThirdView
   • CCreateContext* pContext

SPLIT_PATTERN is an enum defined:

typedef enum 
{
    PATTERN_1 ,
    PATTERN_2 ,
    PATTERN_3 ,
    PATTERN_4 ,
    PATTERN_5 ,
    PATTERN_6 ,

}SPLIT_PATTERN;

Example:

BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)
{
    // TODO: Add your specialized code here and/or call the base class

    m_pTopWndSplitter  = new CExSplitter3Wnd;

    m_pTopWndSplitter->SetStyle(WS_CHILD | WS_VISIBLE | WS_BORDER);
    m_pTopWndSplitter->SetFirstViewSize(CSize(100,100));
    m_pTopWndSplitter->SetSecondViewSize(CSize(100,200));
    m_pTopWndSplitter->SetThirdViewSize(CSize(100,100));
    m_pTopWndSplitter->SetPattern(this,PATTERN_1,
        RUNTIME_CLASS(CTestSplitView),RUNTIME_CLASS(CSecView),
        RUNTIME_CLASS(CThirdView),pContext);
    return TRUE;
}

You can retrieve the different view sizes by calling one of the dimension functions. Each view (first, second, third) has its own function:

void GetFirsWndDim(int* nCurrDim,int* nMinDim);
void GetSecWndDim(int* nCurrDim,int* nMinDim);
void GetThirdWndDim(int* nCurrDim,int* nMinDim);
