Detect if window is split

Many times it is necessary to know whether a view is currently split or not. This method will return TRUE if the view is split and FALSE if it is not. NOTE: It does NOT detect multiple views, so don’t use it to determine whether UpdateAllViews should be called!

int CMySplitterView::IsSplit(void)
{
	CSplitterWnd * parent;
	parent = (CSplitterWnd*)GetParent();
	int rows;
	rows = parent->GetRowCount();
	if(rows>1)
	{
		return(TRUE);
	}
	int cols;
	cols = parent->GetColumnCount();
	if(cols>1)
	{
		return(TRUE);
	}
	return(FALSE);
}
