Member Function Documentation

int columnCount ( const QModelIndex &  parent = QModelIndex() ) const

virtual

Implementation of QAbstractItemModel::columnCount().

Returns

Always returns 1.

Definition at line 99 of file PropertyModel.cpp.

void current_index_changed ( const QModelIndex &  newIndex, const QModelIndex &  oldIndex  )

privateslot

Slot called when the current index has changed in the tree model.

Parameters

newIndex	New current index.
oldIndex	Old current index.

Definition at line 118 of file PropertyModel.cpp.

QVariant data ( const QModelIndex &  index, int  role  ) const

virtual

Destructor.

Frees all allocated memory. Implementation of QAbstractItemModel::data(). Only the role Qt::DisplayRole is accepted. Other roles will result to the return of an empty QVariant object (built with the default construtor).

Parameters

index	Concerned item index.
role	Role of the returned value (only Qt::DisplayRole).

Returns

Returns an empty QVariant object if the role is not Qt::DecorationRole or if the index is not valid. Otherwise, returns the nodename of the item at the specified index.

Definition at line 39 of file PropertyModel.cpp.

void empty_list ( )

private

Clean the model data.

Definition at line 141 of file PropertyModel.cpp.

QVariant headerData ( int  section, Qt::Orientation  orientation, int  role = Qt::DisplayRole  ) const

virtual

Gives header titles.

Overrides QAbstractItemModel::headerData().

Parameters

section	Section number.
orientation	Header orientation.
role	Data role. Only Qt::DisplayRole is accepted.

Returns

Returns the data or an empty QVariant on error.

Definition at line 106 of file PropertyModel.cpp.

QModelIndex index ( int  row, int  column, const QModelIndex &  parent = QModelIndex()  ) const

virtual

Implementation of QAbstractItemModel::index().

Gives the index of the item at the given row and column under the given parent. If the parent index is not valid, the root item is taken as parent.

Parameters

row	Item row from the parent.
column	Item column.
parent	Item parent.

Returns

Returns the requested index, or a nullptr index if hasIndex(row, column, parent) returns false.

Definition at line 63 of file PropertyModel.cpp.

QModelIndex parent ( const QModelIndex &  child ) const

virtual

Implementation of QAbstractItemModel::parent()->

Parameters

child

Item index of which we would like to know the parent.

Returns

Returns the parent index of the given child or a nullptr index if the child is not a valid index.

Definition at line 82 of file PropertyModel.cpp.

int rowCount ( const QModelIndex &  parent = QModelIndex() ) const

virtual

Implementation of QAbstractItemModel::rowCount().

If the parent index is not valid, the root item is taken as parent.

Returns

Returns the row count (number of children) of a given parent.
