I am trying to display a tooltip over a cell. I have extended the GridTextBoxCellRenderer class and have overridden OnMouseHover, OnMouseHoverLeave, OnMouseDown and OnDraw to implement the tooltip code. A collegue previously overrode the OnHitTest method to return 1 so that the mouse events would fire.
The problem is: returning 1 from the OnHitTest method causes the mouse multi selection of cells to not work anymore. Conversely returning 0 from OnHitTest means selections work fine but no mouse events are raised.
Is there a (nice) way of enabling both selecting and mouse events?
