Detailed Description

template<class T, class IS = QDataStream, class OS = QDataStream>
class quark::gui::BasicFilterTreeModel< T, IS, OS >

An abstract subclass of QSortFilterProxyModel for sorting and filtering of AbstractTreeModels.

Subclasses must provide a suitable public constructor and implement filterAcceptsItem(), filterAcceptsField(), and/or fieldLessThan().

Template Parameters

T	The type template parameter of the AbstractTableModel.
IS	The input stream template parameter of the AbstractTableModel.
OS	The output stream template parameter of the AbstractTableModel.

Constructor & Destructor Documentation

~BasicFilterTreeModel()

virtual ~BasicFilterTreeModel ( )

virtual

Destructor.

BasicFilterTreeModel()

BasicFilterTreeModel ( BasicTreeModel< T, IS, OS > *  sourceModel, QObject *  parent = NULL  )

protected

Constructs a new BasicFilterTreeModel with the given source model.

Member Function Documentation

fieldLessThan()

virtual bool fieldLessThan ( int  field, const QVariant &  value1, const QVariant &  value2  ) const

protectedvirtual

Compares the values of a given field of two items in the model, for the purpose of sorting.

The default implementation compares the string representations of the two values.

Parameters

field	The field number.
value1	The field's value in the first item.
value2	The field's value in the second item.

Returns

true if value1 < value2, false otherwise.

filterAcceptsField()

virtual bool filterAcceptsField ( int  field ) const

protectedvirtual

Called to test whether a given field in the model is accepted by this filter.

The default implementation is a no-op that returns true.

Parameters

field

The field number to filter.

Returns

true if the filter accepts the ifield, false otherwise.

filterAcceptsItem()

virtual bool filterAcceptsItem ( const T &  item ) const

protectedvirtual

Called to test whether a given item in the model is accepted by this filter.

The default implementation is a no-op that returns true.

Parameters

item	The item to filter.

Returns

true if the filter accepts the item, false otherwise.

getItemForIndex()

T* getItemForIndex

(

const QModelIndex &

index

)

const

Returns the filtered item at the given index in this model.

sourceModel()

BasicTreeModel<T, IS, OS>* sourceModel ( ) const

inline

Returns this filter model's source model.
