Public Member Functions | |
AbstractAreaWidget (QWidget *parent=0) | |
void | alignToReferencePoint (const RelativePosition &position) |
BackgroundAttributes | backgroundAttributes () const |
bool | compare (const AbstractAreaBase *other) const |
Returns true if both areas have the same settings. | |
virtual void | forceRebuild () |
Call this to trigger an unconditional re-building of the widget's internals. | |

virtual void | paint (QPainter *painter)=0 |
Overwrite this to paint the inner contents of your widget. | |
void | paintAll (QPainter &painter) |
Call paintAll, if you want the background and the frame to be drawn before the normal paint() is invoked automatically. | |
virtual void | paintBackground (QPainter &painter, const QRect &rectangle) |
virtual void | paintEvent (QPaintEvent *event) |
Draws the background and frame, then calls paint(). | |
