You're correct that m_wndSplitter.IdFromRowCol(0, 0) would refer to the
first row and the first column.
But I think your assertion is caused by the fact that the first row/column
has a view assigned to it already. Tell us what the assert is, and where
it's coming from.
If you would tell us what you would like your view to look like, we might be
able to suggest code. For example, the following code, which is from
CChildFrame::OnCreateClient, will make one vertical column on the left, and
two rows one over the other on the right, such that your view looks like
this:
----------------
| | |
| |-------|
| | |
---------------
(Sorry for proportional/fixed font issues)
BOOL CChildFrame::OnCreateClient( LPCREATESTRUCT /*lpcs*/,
CCreateContext* pContext)
{
// create vertical splitter window first
if ( !m_wndSplitterVert.CreateStatic(this, 1, 2) )
return FALSE;
// now create horizontal splitter window inside right-hand pane of vertical
splitter
if ( !m_wndSplitterHoriz.CreateStatic( &m_wndSplitterVert, // our parent
window is the first splitter
2, 1, // the new splitter is 2 rows by 1 column
WS_CHILD | WS_VISIBLE | WS_BORDER, // style, WS_BORDER is needed
m_wndSplitterVert.IdFromRowCol(0, 1) ) ) // new splitter is in the
first row, second column of main splitter
return FALSE;
// set up target sizes for the windows
// overall, the window area of the frame should be around two-thirds of the
// available area on the screen
int cx = ::GetSystemMetrics(SM_CXSCREEN);
int cy = ::GetSystemMetrics(SM_CYSCREEN);
int cyNonClient = ::GetSystemMetrics(SM_CYCAPTION) +
2*::GetSystemMetrics(SM_CYMENU);
cx = (int) (.667*cx);
cy = (int) (.667*cy);
// insert views into panes, with desired sizes
// left-hand pane should be around one-fourth of view area
// vertical splitter first ....
if ( !m_wndSplitterVert.CreateView(0, 0,
RUNTIME_CLASS(CWebScraperSitesView), CSize( (int)(0.25*cx),
cy-cyNonClient ), pContext) )
{
m_wndSplitterVert.DestroyWindow();
m_wndSplitterHoriz.DestroyWindow();
return FALSE;
}
// ... then horizontal splitter on right-hand side of vertical splitter
// top pane (the request) around one-quarter of available area
if ( !m_wndSplitterHoriz.CreateView(0, 0,
RUNTIME_CLASS(CWebScraperRequestView), CSize( (int)(0.75*cx),
(int)(0.25*cy)-cyNonClient ), pContext) ||
!m_wndSplitterHoriz.CreateView(1, 0, RUNTIME_CLASS(CWebScraperReplyView),
CSize( (int)(0.75*cx), (int)(0.75*cy)-cyNonClient ), pContext) )
{
m_wndSplitterVert.DestroyWindow();
m_wndSplitterHoriz.DestroyWindow();
return FALSE;
}
return TRUE;
}
