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()
|
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()
|
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()
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()
|
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.
