Detailed Description

The ParameterDelegate class implements special delegates for the QTreeWidget class used in the parameterGUI. The QTreeWidget class provides some different standard delegates for editing parameters shown in the tree structure. The ParameterDelegate class provides special editors for the different types of parameters defined in the ParameterHandler class. For all parameter types based on strings as "Anything", "MultipleSelection" "Map" and "List" a simple line editor will be shown up. In the case of integer and double type parameters the editor is a spin box and for "Selection" type parameters a combo box will be shown up. For parameters of type "FileName" and "DirectoryName" the delegate shows a BrowseLineEdit editor. The column of the tree structure with the parameter values has to be set in the constructor.

Note: This class is used in the graphical user interface for the ParameterHandler class. It is not compiled into the deal.II libraries and can not be used by applications using deal.II.
