Functions

◆ columnCount()

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

virtual

Returns the number of columns for the children of the given parent.

In most subclasses, the number of columns is independent of the parent.

For example:

int DomModel::columnCount(const QModelIndex &/*parent*/) const
{
    return 3;
}

Note: When implementing a table based model, columnCount() should return 0 when the parent is valid.

See also: rowCount()

Definition at line 1075 of file qprintdialog_unix.cpp.

 {
     return 2;
 }

◆ data()

QVariant QPPDOptionsModel::data	(	const QModelIndex &	index,
		int	role = `Qt::DisplayRole`
	)		const

virtual

Returns the data stored under the given role for the item referred to by the index.

Note: If you do not have a value to return, return an invalid QVariant instead of returning 0.

Implements QAbstractItemModel.

             return QVariant();
     }
     if (role != Qt::DisplayRole)
         return QVariant();
 }

◆ flags()

Qt::ItemFlags QPPDOptionsModel::flags ( const QModelIndex & index ) const

virtual

Returns the item flags for the given index.

The base class implementation returns a combination of flags that enables the item (ItemIsEnabled) and allows it to be selected (ItemIsSelectable).

See also: Qt::ItemFlags

Reimplemented from QAbstractItemModel.

Definition at line 1156 of file qprintdialog_unix.cpp.

 {
     if (!index.isValid() || reinterpret_cast<QOptionTreeItem*>(index.internalPointer())->type == QOptionTreeItem::Group)
         return Qt::ItemIsEnabled;
 
     if (index.column() == 1)
         return Qt::ItemIsEnabled | Qt::ItemIsSelectable | Qt::ItemIsEditable;
 
     return Qt::ItemIsEnabled | Qt::ItemIsSelectable;
 }

◆ headerData()

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

virtual

Returns the data for the given role and section in the header with the specified orientation.

For horizontal headers, the section number corresponds to the column number. Similarly, for vertical headers, the section number corresponds to the row number.

See also: Qt::ItemDataRole, setHeaderData(), QHeaderView

Reimplemented from QAbstractItemModel.

Definition at line 1234 of file qprintdialog_unix.cpp.

 {
     if (role != Qt::DisplayRole)
         return QVariant();
 
     switch(section){
         case 0:
             return QVariant(QApplication::translate("QPPDOptionsModel", "Name"));
         case 1:
             return QVariant(QApplication::translate("QPPDOptionsModel", "Value"));
         default:
             return QVariant();
     }
 }

◆ index()

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

virtual

Returns the index of the item in the model specified by the given row, column and parent index.

When reimplementing this function in a subclass, call createIndex() to generate model indexes that other components can use to refer to items in your model.

See also: createIndex()

Implements QAbstractItemModel.

     else
         itm = reinterpret_cast<QOptionTreeItem*>(parent.internalPointer());
 
     return createIndex(row, column, itm->childItems.at(row));
 }

◆ parent()

QModelIndex QPPDOptionsModel::parent ( const QModelIndex & index ) const

virtual

Returns the parent of the model item with the given index.

Warning: This function is not part of the public interface.

If the item has no parent, an invalid QModelIndex is returned.

A common convention used in models that expose tree data structures is that only items in the first column have children. For that case, when reimplementing this function in a subclass the column of the returned QModelIndex would be 0.

When reimplementing this function in a subclass, be careful to avoid calling QModelIndex member functions, such as QModelIndex::parent(), since indexes belonging to your model will simply call your implementation, leading to infinite recursion.

◆ rowCount()

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

virtual

Returns the number of rows under the given parent.

When the parent is valid it means that rowCount is returning the number of children of parent.

Note: When implementing a table based model, rowCount() should return 0 when the parent is valid.

See also: columnCount()

Implements QAbstractItemModel.
