void QmitkScalarBarOverlay::GenerateData

(

mitk::PropertyList::Pointer

pl )

[virtual]

Setup the QLabel with overlay specific information.

First, this method sets text-overlay specific properties as described in the class docu above. Secondly, the actual text of the label is set.

No error will be issued if the property containing the text is not found, the TextOverlay will show an empty string!

Reimplemented from QmitkOverlay.

void QmitkScalarBarOverlay::GetProperties

(

mitk::PropertyList::Pointer

pl )

[protected]

internal helper class to determine text-properties

This method is only used internally to apply the text specific properties that can be set using a mitk::PropertyList. If a property cannot be found, a default value is used.

The values of these properties are then attributed to the label using QFont and QPalette.
