Qt Signals

• void updatePreviewWidget (const QModelIndex&)

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.

See also Model/View Programming.

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.

int-list 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&).

int QColumnView.horizontalOffset (self)

QModelIndex QColumnView.indexAt (self, QPoint point)

bool QColumnView.isIndexHidden (self, QModelIndex index)

QModelIndex QColumnView.moveCursor (self, QAbstractItemView.CursorAction cursorAction, Qt.KeyboardModifiers modifiers)

QWidget QColumnView.previewWidget (self)

Returns the preview widget, or 0 if there is none.

See also setPreviewWidget() and updatePreviewWidget().

QColumnView.resizeEvent (self, QResizeEvent event)

bool QColumnView.resizeGripsVisible (self)

QColumnView.scrollContentsBy (self, int dx, int dy)

QColumnView.scrollTo (self, QModelIndex index, QAbstractItemView.ScrollHint hint = QAbstractItemView.EnsureVisible)

QColumnView.selectAll (self)

QColumnView.setColumnWidths (self, int-list list)

Sets the column widths to the values given in the list. Extra values in the list are kept and used when the columns are created.

See also columnWidths() and createColumn().

QColumnView.setModel (self, QAbstractItemModel model)

QColumnView.setPreviewWidget (self, QWidget widget)

The widget argument has it's ownership transferred to Qt.

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() and updatePreviewWidget().

QColumnView.setResizeGripsVisible (self, bool visible)

QColumnView.setRootIndex (self, QModelIndex index)

QColumnView.setSelection (self, QRect rect, QItemSelectionModel.SelectionFlags command)

QColumnView.setSelectionModel (self, QItemSelectionModel selectionModel)

QSize QColumnView.sizeHint (self)

int QColumnView.verticalOffset (self)

QRect QColumnView.visualRect (self, QModelIndex index)

QRegion QColumnView.visualRegionForSelection (self, QItemSelection selection)

Qt Signal Documentation

void updatePreviewWidget (const QModelIndex&)

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