Detailed Description

The QColumnView class provides a model/view implementation of a column view.

QColumnView displays a model in a number of QListViews, one for each hierarchy in the tree. This is sometimes referred to as a cascading list.

The QColumnView class is one of the Model/View Classes and is part of Qt's model/view framework.

QColumnView implements the interfaces defined by the QAbstractItemView class to allow it to display data provided by models derived from the QAbstractItemModel class.

Method Documentation

QColumnView.init (self, QWidget parent = None)

The parent argument, if not None, causes self to be owned by Qt instead of PyQt.

Constructs a column view with a parent to represent a model's data. Use setModel() to set the model.

See also QAbstractItemModel.

list-of-int QColumnView.columnWidths (self)

Returns a list of the width of all the columns in this view.

See also setColumnWidths().

QAbstractItemView QColumnView.createColumn (self, QModelIndex rootIndex)

To use a custom widget for the final column when you select an item overload this function and return a widget. index is the root index that will be assigned to the view.

Return the new view. QColumnView will automatically take ownership of the widget.

See also setPreviewWidget().

QColumnView.currentChanged (self, QModelIndex current, QModelIndex previous)

This method is also a Qt slot with the C++ signature void currentChanged(const QModelIndex&,const QModelIndex&).

Reimplemented from QAbstractItemView.currentChanged().

int QColumnView.horizontalOffset (self)

Reimplemented from QAbstractItemView.horizontalOffset().

QModelIndex QColumnView.indexAt (self, QPoint point)

Reimplemented from QAbstractItemView.indexAt().

QColumnView.initializeColumn (self, QAbstractItemView column)

Copies the behavior and options of the column view and applies them to the column such as the iconSize(), textElideMode() and alternatingRowColors(). This can be useful when reimplementing createColumn().

This function was introduced in Qt 4.4.

See also createColumn().
