virtual CBCGPSize CBCGPChartLegendCell::CalcSize ( CBCGPGraphicsManager *  pGM )

virtual

Called to calculate cell size

This method is called by legend to calculate cell size. You have to override this method in a derived class if you wish to display a custom content in a "standard" cell. The calculated size should be stored in m_szCellSize member.

You can override OnCalcCustomCellSize to provide custom size for a cell of LCT_CUSTOM style.

If you calculate size based on any D2D resources that are also used to draw cell content, you must call Destroy for these resources (which detaches a resource from graphics manager) before using them in this override. This prevents sharing a resource between two graphics managers (CalcSize can be called outside of OnDraw context and pGM passed to CalcSize differs to the one passed to OnDraw).

Parameters

pGM	a pointer to a graphics manager
