Destructor.
| DtResizableCircleSymbol::DtResizableCircleSymbol | ( | ) | [private] |
Not implemented. Private to ensure it is only constructed with a drawer.
| DtResizableCircleSymbol& DtResizableCircleSymbol::operator= | ( | const DtResizableCircleSymbol & | orig | ) |
Assignment Operator.
| virtual DtSymbol* DtResizableCircleSymbol::clone | ( | ) | const [virtual] |
Create a clone of this symbol.
Reimplemented from DtCircleSymbol.
| virtual bool DtResizableCircleSymbol::originSelected | ( | ) | const [virtual] |
The following methods will test the particular selection flags and return true if the particular flag is set.
| virtual bool DtResizableCircleSymbol::circleSelected | ( | ) | const [virtual] |
| virtual bool DtResizableCircleSymbol::anythingSelected | ( | ) | const [virtual] |
| virtual QPoint DtResizableCircleSymbol::xOriginPoint | ( | ) | const [virtual] |
Returns xOriginPoint. Set when radius is set.
| virtual QPoint DtResizableCircleSymbol::endPoint | ( | ) | const [virtual] |
| virtual void DtResizableCircleSymbol::setOrigin | ( | int | x, |
| int | y | ||
| ) | [virtual] |
Same as above.
Reimplemented from DtSymbol.
| virtual void DtResizableCircleSymbol::setOrigin | ( | const QPoint & | center | ) | [virtual] |
Set the display coordinate that will become the 0,0 point for drawing this symbol.
On most symbols, this will be the same as the center point, but this doesn not need to be the case
Reimplemented from DtSymbol.
| virtual void DtResizableCircleSymbol::setRadius | ( | const double | r | ) | [virtual] |
Also sets the end point based on the radius.
Reimplemented from DtCircleSymbol.
| virtual void DtResizableCircleSymbol::setOriginRadius | ( | double | r | ) | [virtual] |

| virtual bool DtResizableCircleSymbol::createFixed | ( | ) | const [virtual] |
| virtual int DtResizableCircleSymbol::pointSelected | ( | ) | const [virtual] |
