Called to draw grid lines around cells
You can override this method in a derived class to customize drawing of grid lines. The default implementation loops over encapsulated cells and draws their borders. A bounding rectangle of next cell should be based on the "rect" parameter and previous cell sizes. For vertical layout the width of each cell is taken from CBCGPChartLegendVisualObject::GetColumnWidth, for horizontal layout - from CBCGPChartLegendCell::GetSize.
- Parameters
-
| pGM | a pointer to a graphics manager |
| rect | specifies a bounding rectangle of an entry |
