Detailed Description

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

AbstractArea is the base class for all non-widget chart elements that have a set of background attributes and frame attributes, such as coordinate planes or axes.

Note
This class inherits from AbstractAreaBase, AbstractLayoutItem, QObject. The reason for this triple inheritance is that neither AbstractAreaBase nor AbstractLayoutItem are QObject.

Member Function Documentation

QRect AbstractArea::areaGeometry ( ) const
overrideprotectedvirtual

This internal method is used by AbstractArea and AbstractAreaWidget to find out the real widget size.

See also
AbstractArea, AbstractAreaWidget

Implements KChart::AbstractAreaBase.

Definition at line 148 of file KChartAbstractArea.cpp.

int AbstractArea::bottomOverlap ( bool  doNotRecalculate = false) const
virtual

This is called at layout time by KChart:AutoSpacerLayoutItem::sizeHint().

The method triggers AbstractArea::sizeHint() to find out the amount of overlap at the bottom edge of the area.

Note
The default implementation is not using any caching, it might make sense to implement a more sophisticated solution for derived classes that have complex work to do in sizeHint(). All we have here is a primitive flag to be set by the caller if it is sure that no sizeHint() needs to be called.

Definition at line 95 of file KChartAbstractArea.cpp.

int AbstractArea::leftOverlap ( bool  doNotRecalculate = false) const
virtual

This is called at layout time by KChart::AutoSpacerLayoutItem::sizeHint().

The method triggers AbstractArea::sizeHint() to find out the amount of overlap at the left edge of the area.

Note
The default implementation is not using any caching, it might make sense to implement a more sophisticated solution for derived classes that have complex work to do in sizeHint(). All we have here is a primitive flag to be set by the caller if it is sure that no sizeHint() needs to be called.

Definition at line 71 of file KChartAbstractArea.cpp.

void AbstractArea::paintAll ( QPainter painter)
overridevirtual

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

Reimplemented from KChart::AbstractLayoutItem.

Reimplemented in KChart::TernaryAxis.

Definition at line 117 of file KChartAbstractArea.cpp.

void AbstractArea::paintIntoRect ( QPainter painter,
const QRect rect 
)
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 AbstractLayoutItem::paint() instead.

Definition at line 105 of file KChartAbstractArea.cpp.

void AbstractArea::positionHasChanged ( )
overrideprotectedvirtual

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 from KChart::AbstractAreaBase.

Definition at line 153 of file KChartAbstractArea.cpp.

int AbstractArea::rightOverlap ( bool  doNotRecalculate = false) const
virtual

This is called at layout time by KChart::AutoSpacerLayoutItem::sizeHint().

The method triggers AbstractArea::sizeHint() to find out the amount of overlap at the right edge of the area.

Note
The default implementation is not using any caching, it might make sense to implement a more sophisticated solution for derived classes that have complex work to do in sizeHint(). All we have here is a primitive flag to be set by the caller if it is sure that no sizeHint() needs to be called.

Definition at line 79 of file KChartAbstractArea.cpp.

int AbstractArea::topOverlap ( bool  doNotRecalculate = false) const
virtual

This is called at layout time by KChart::AutoSpacerLayoutItem::sizeHint().

The method triggers AbstractArea::sizeHint() to find out the amount of overlap at the top edge of the area.

Note
The default implementation is not using any caching, it might make sense to implement a more sophisticated solution for derived classes that have complex work to do in sizeHint(). All we have here is a primitive flag to be set by the caller if it is sure that no sizeHint() needs to be called.
