|
|
* legends or axes.

* @note Normally you should not use AbstractAreaBase directly, but
|
|
* derive your classes from AbstractArea or AbstractAreaWidget.
|
|
*
|
|
* @note 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.
