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:
- Override the
OnCreateClient
function in your SDI MainFrame
. - Construct a new
CExSplitter3Wnd
object. - Set style and initial view sizes.
- 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)
{
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);
