Detailed Description

A text area in the chart with a background, a frame, etc.

TextArea is the base class for all text containing non-widget chart elements that have a set of background attributes and frame attributes, such as headers or footers.

Note

This class inherits AbstractAreaBase, TextLayoutItem, and QObject. The reason for this triple inheritance is that neither AbstractAreaBase nor TextLayoutItem inherit QObject.

Member Function Documentation

areaGeometry()

QRect TextArea::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 88 of file KChartTextArea.cpp.

paintAll()

void TextArea::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.

Definition at line 66 of file KChartTextArea.cpp.

paintIntoRect()

void TextArea::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 TextLayoutItem::paint() instead.

Definition at line 54 of file KChartTextArea.cpp.

positionHasChanged()

void TextArea::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 93 of file KChartTextArea.cpp.
