Member Function Documentation
| virtual ColorType PolygonPlotObject::getFillColor | ( | ) | const [pure virtual] |
Returns the polygon fill color.
- Returns:
- The polygon fill color
| virtual FillStyle PolygonPlotObject::getFillStyle | ( | ) | const [pure virtual] |
| virtual SymbolType PolygonPlotObject::getHatchStyle | ( | ) | const [pure virtual] |
| virtual bool PolygonPlotObject::isFilled | ( | ) | const [pure virtual] |
Returns the fill state of the polygon.
- Returns:
- True, is filled, false is not filled
| virtual bool PolygonPlotObject::hit | ( | LocationType | point | ) | const [pure virtual] |
Determines if this plot object resides at this point, most likely a mouse click.
- Parameters:
-
point The location of the mouse click
- Returns:
- True if the plot object is at this point. This check includes the center if the object is filled, otherwise it only includes the outline.
