Member Function Documentation

FWTableCellRendererBase * FWTableViewTableManager::cellRenderer	(	int	iSortedRowNumber,
		int	iCol
	)		const `[virtual]`

Returns the particular renderer used to handle the requested cell. Arguments: iSortedRowNumber: the row number from the present sort (i.e. the cell number of the view) iCol: the column number of the cell. The returned value must be used immediately and not held onto since the same Renderer can be used for subsequent calls
