Member Function Documentation

virtual void gutz::Counted::_decCount (   )  [inline, protected, virtual, inherited]

gutz::Counted interface, decrement reference count by one. Not generaly used by subclasses, mostly for collaboration with gutz::SmartPtr. Sometimes you need to call this though, see the documentation for gutz::SmartPtr Definition at line 54 of file smartptr.h. Referenced by TFImage::clear(), NrroImage::fBlendOverRGBA(), and Nrro::updateMinMax().

virtual int gutz::Counted::_getCount (   )  const [inline, protected, virtual, inherited]

gutz::Counted interface, get the current reference count. Not generaly used by subclasses, mostly for collaboration with gutz::SmartPtr. Definition at line 58 of file smartptr.h.

virtual void gutz::Counted::_incCount (   )  [inline, protected, virtual, inherited]

gutz::Counted interface, increment reference count by one. Not generaly used by subclasses, mostly for collaboration with gutz::SmartPtr. Sometimes you need to call this though, see the documentation for gutz::SmartPtr Definition at line 48 of file smartptr.h. Referenced by TFImage::clear(), NrroImage::fBlendOverRGBA(), and Nrro::updateMinMax().

virtual QPointArray CanvasItemIF::areaPoints (   )  const [pure virtual, inherited]

You have to override these! polygonalItem interface stuff. Implemented in EdgeItem, NodeItem, and PolygonEdit.

virtual void CanvasItemIF::drawShape (  QPainter &  p  )  [pure virtual, inherited]

polygonalItem interface stuff Implemented in EdgeItem, NodeItem, and PolygonEdit.

bool CanvasItemIF::getUpdateLinks (   )  const [inline, inherited]

do you want this object to update other objects that are linked to it? Definition at line 117 of file commonQt/canvas/CanvasItems.h. References CanvasItemIF::_updateLinks.

void CanvasItemIF::setActive (  bool  yes  )  [virtual, inherited]

has it been selected and modifiable as a group? bool isActive() declared in QCanvasItem Definition at line 68 of file CanvasItems.cpp.
