Detailed Description
Base class for AbstractArea and AbstractAreaWidget: An area in the chart with a background, a frame, etc.
AbstractAreaBase is the base class for all chart elements that have a set of background attributes and frame attributes, such as legends or axes.
- Note
- Normally you should not use AbstractAreaBase directly, but derive your classes from AbstractArea or AbstractAreaWidget.
- This classis not a QObject, so it is easier to inherit from it, if your are inheriting from a QObject too like AbstractAreaWidget does it.

Member Function Documentation
◆ areaGeometry()
|
protectedpure virtual |
This internal method is used by AbstractArea and AbstractAreaWidget to find out the real widget size.
- See also
- AbstractArea, AbstractAreaWidget
Implemented in KChart::AbstractArea, KChart::AbstractAreaWidget, and KChart::TextArea.
◆ compare()
bool AbstractAreaBase::compare | ( | const AbstractAreaBase * | other | ) | const |
Returns true if both areas have the same settings.
Definition at line 57 of file KChartAbstractAreaBase.cpp.
◆ getFrameLeadings()
void AbstractAreaBase::getFrameLeadings | ( | int & | left, |
int & | top, | ||
int & | right, | ||
int & | bottom | ||
) | const |
- Note
- Normally you should not call this method, but derive your classes from AbstractArea or AbstractAreaWidget.

◆ positionHasChanged()
|
protectedvirtual |
This internal method can be overwritten by derived classes, if they want to emit a signal (or perform other actions, resp.) when the Position of the area has been changed. The default implementation does nothing.
Reimplemented in KChart::AbstractArea, KChart::AbstractAreaWidget, and KChart::TextArea.
