Detailed Description

An area in the chart with a background, a frame, etc.

AbstractAreaWidget is the base for all widget classes that have a set of background attributes and frame attributes, such as KDChart::Chart and KDChart::Legend.

void AbstractAreaWidget::needSizeHint ( ) [virtual]

Call this to trigger an conditional re-building of the widget's internals.

e.g. AbstractAreaWidget call this, before calling layout()->setGeometry()

Reimplemented in KDChart::Legend.

Definition at line 83 of file KDChartAbstractAreaWidget.cpp.

virtual void KDChart::AbstractAreaWidget::paint ( QPainter * painter ) [pure virtual]

Overwrite this to paint the inner contents of your widget.

Note:: When overriding this method, please let your widget draw itself at the top/left corner of the painter. You should call rect() (or width(), height(), resp.) to find the drawable area's size: While the paint() method is being executed the frame of the widget is outside of its rect(), so you can use all of rect() for your custom drawing!

See also:: paint, paintIntoRect

Implemented in KDChart::Legend.

void AbstractAreaWidget::paintAll ( QPainter & painter )

Call paintAll, if you want the background and the frame to be drawn before the normal paint() is invoked automatically.

void AbstractAreaWidget::paintEvent ( QPaintEvent * event ) [virtual]

Draws the background and frame, then calls paint().

In most cases there is no need to overwrite this method in a derived class, but you would overwrite paint() instead.
