Detailed Description

The QColumnView class provides a model/view implementation of a column view. This class can be used to display a model in a number of QListViews, one for each hierarchy in the tree. This is sometimes referred to as a cascading list. QColumnView implements the interfaces defined by the QAbstractItemView class to allow it to display data provided by models derived from the QAbstractItemModel class.

The QColumnView class is one of the Model/View Classes.

Constructor & Destructor Documentation

QColumnView::QColumnView ( QWidget parent = nullptr)
explicit

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

See also
QAbstractItemModel
QColumnView::~QColumnView ( )

Destroys the column view.

Method Documentation

QList< int > QColumnView::columnWidths ( ) const

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

See also
setColumnWidths()
QAbstractItemView * QColumnView::createColumn ( const QModelIndex index)
protectedvirtual

The index is the root index that will be assigned to the view. Returns a new QAbstractItemView.

To use a custom widget for the final column when you select an item, overload this method and return your custom widget. QColumnView will take ownership of the widget you returned.

See also
setPreviewWidget()
void QColumnView::currentChanged ( const QModelIndex current,
const QModelIndex previous 
)
overrideprotected
int QColumnView::horizontalOffset ( ) const
overrideprotectedvirtual

Returns the horizontal offset of the view.

In the base class this is a pure virtual function.

See also
verticalOffset()

Implements QAbstractItemView.

QModelIndex QColumnView::indexAt ( const QPoint point) const
overridevirtual

Returns the model index of the item at the viewport coordinates point.

In the base class this is a pure virtual function.

See also
visualRect()

Implements QAbstractItemView.

void QColumnView::initializeColumn ( QAbstractItemView column) const
protected

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().

See also
createColumn()
bool QColumnView::isIndexHidden ( const QModelIndex index) const
overrideprotectedvirtual

Returns true if the item referred to by the given index is hidden in the view, otherwise returns false. The way items are hidden depends on the view. For example TableView allows hiding columns and TreeView allows rows.

Implements QAbstractItemView.

QModelIndex QColumnView::moveCursor ( CursorAction  cursorAction,
Qt::KeyboardModifiers  modifiers 
)
overrideprotectedvirtual

If cursorAction is MoveLeft this method will return the parent index. If cursorAction is MoveRight this method will return the child index or the index of the next item if there is no child.

Implements QAbstractItemView.

QWidget * QColumnView::previewWidget ( ) const

Returns the preview widget or nullptr if there is no preview widget.

See also
setPreviewWidget(), updatePreviewWidget()
void QColumnView::resizeEvent ( QResizeEvent event)
overrideprotectedvirtual

Reimplemented from QWidget::resizeEvent().

This function is called with the given event when a resize event is sent to the widget.

See also
QWidget::resizeEvent()

Reimplemented from QAbstractItemView.

bool QColumnView::resizeGripsVisible ( ) const

Property documentation pending.

void QColumnView::scrollContentsBy ( int  dx,
int  dy 
)
overrideprotectedvirtual

This virtual handler is called when the scroll bars are moved by dx, dy, and consequently the viewport's contents should be scrolled accordingly.

The default implementation simply calls update() on the entire viewport(). Subclasses can reimplement this handler for optimization purposes, or as with QScrollArea to move a contents widget. The parameters dx and dy are there for convenience, so that the class knows how much should be scrolled. You may ignore these values and scroll directly to the position the scroll bars indicate.

Calling this method in order to scroll programmatically is an error, use the scroll bars instead (e.g. by calling QScrollBar::setValue() directly).

Reimplemented from QAbstractScrollArea.

void QColumnView::scrollTo ( const QModelIndex index,
ScrollHint  hint = EnsureVisible 
)
overridevirtual

Scrolls the view if necessary to ensure that the item at index is visible. The view will try to position the item according to the given hint.

In the base class this is a pure virtual function.

Implements QAbstractItemView.

void QColumnView::setColumnWidths ( const QList< int > &  list)

Sets the column widths to the values given in the list. If the list contains too few values, the width of the remaining columns will not be modified.

See also
columnWidths(), createColumn()
void QColumnView::setModel ( QAbstractItemModel model)
overridevirtual

Reimplemented from QAbstractItemView::setModel().

Reimplemented from QAbstractItemView.

void QColumnView::setPreviewWidget ( QWidget widget)

Sets the preview widget. The widget becomes a child of the column view and will be destroyed when the column area is deleted or when a new widget is set.

See also
previewWidget(), updatePreviewWidget()
void QColumnView::setResizeGripsVisible ( bool  visible)

Property documentation pending.

void QColumnView::setSelection ( const QRect rect,
QItemSelectionModel::SelectionFlags  flags 
)
overrideprotectedvirtual

Applies the selection flags to the items in or touched by the rectangle, rect.

When implementing your own itemview setSelection should call selectionModel()->select(selection, flags) where selection is either an empty QModelIndex or a QItemSelection that contains all items that are contained in rect.

See also
selectionCommand(), selectedIndexes()

Implements QAbstractItemView.

void QColumnView::setSelectionModel ( QItemSelectionModel selectionModel)
overridevirtual

Sets the current selection model to the given selectionModel. If you call setModel() after this function, the given selectionModel will be replaced by one created by the view.

Note
It is up to the application to delete the old selection model if it is no longer needed; i.e., if it is not being used by other views. This will happen automatically when its parent object is deleted. However, if it does not have a parent, or if the parent is a long-lived object, it may be preferable to call its deleteLater() function to explicitly delete it.
See also
selectionModel(), setModel(), clearSelection()

Reimplemented from QAbstractItemView.

QSize QColumnView::sizeHint ( ) const
overridevirtual

Returns the value of the sizeHint property.

Reimplemented from QWidget.

void QColumnView::updatePreviewWidget ( const QModelIndex index)
signal

This signal is emitted when the preview widget should be updated to provide rich information about index.

See also
previewWidget()
int QColumnView::verticalOffset ( ) const
overrideprotectedvirtual

Returns the vertical offset of the view.

In the base class this is a pure virtual function.

See also
horizontalOffset()

Implements QAbstractItemView.

QRect QColumnView::visualRect ( const QModelIndex index) const
overridevirtual

Returns the rectangle on the viewport occupied by the item at index.

If your item is displayed in several areas then visualRect should return the primary area that contains index and not the complete area that index might encompasses, touch or cause drawing.

In the base class this is a pure virtual function.

See also
indexAt(), visualRegionForSelection()

Implements QAbstractItemView.

QRegion QColumnView::visualRegionForSelection ( const QItemSelection selection) const
overrideprotectedvirtual

Returns the region from the viewport of the items in the given selection.

In the base class this is a pure virtual function.

visualRect(), selectedIndexes()

Implements QAbstractItemView.
