详细描述

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.

QColumnView 类是一种 模型/视图类 且属于 Qt 的 模型/视图框架 .

QColumnView implements the interfaces defined by the QAbstractItemView 类以允许它显示提供数据，通过模型派生自 QAbstractItemModel 类。

特性文档编制

resizeGripsVisible : bool

This property holds the way to specify if the list views gets resize grips or not

默认情况下， visible is set to true

访问函数：

bool	resizeGripsVisible () const
void	setResizeGripsVisible (bool visible )

另请参阅 setRootIndex ().

成员函数文档编制

QColumnView:: QColumnView ( QWidget * parent = Q_NULLPTR)

Constructs a column view with a parent 来表示模型数据。使用 setModel () 来设置模型。

另请参阅 QAbstractItemModel .

QColumnView:: ~QColumnView ()

Destroys the column view.

QList < int > QColumnView:: columnWidths () const

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

另请参阅 setColumnWidths ().

[virtual protected] QAbstractItemView *QColumnView:: createColumn (const QModelIndex & index )

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.

另请参阅 setPreviewWidget ().

[virtual protected] void QColumnView:: currentChanged (const QModelIndex & current , const QModelIndex & previous )

重实现自 QAbstractItemView::currentChanged ().

[virtual protected] int QColumnView:: horizontalOffset () const

重实现自 QAbstractItemView::horizontalOffset ().

[virtual] QModelIndex QColumnView:: indexAt (const QPoint & point ) const

重实现自 QAbstractItemView::indexAt ().

[protected] void QColumnView:: initializeColumn ( QAbstractItemView * column ) const

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

该函数在 Qt 4.4 引入。

另请参阅 createColumn ().

[virtual protected] bool QColumnView:: isIndexHidden (const QModelIndex & index ) const

重实现自 QAbstractItemView::isIndexHidden ().

[virtual protected] QModelIndex QColumnView:: moveCursor ( CursorAction cursorAction , Qt::KeyboardModifiers modifiers )

重实现自 QAbstractItemView::moveCursor ().

Move left should go to the parent index Move right should go to the child index or down if there is no child

QWidget *QColumnView:: previewWidget () const

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

另请参阅 setPreviewWidget () 和 updatePreviewWidget ().

[virtual protected] void QColumnView:: resizeEvent ( QResizeEvent * event )

重实现自 QWidget::resizeEvent ().

[virtual protected] void QColumnView:: rowsInserted (const QModelIndex & parent , int start , int end )

重实现自 QAbstractItemView::rowsInserted ().

[virtual protected] void QColumnView:: scrollContentsBy ( int dx , int dy )

重实现自 QAbstractScrollArea::scrollContentsBy ().

[virtual] void QColumnView:: scrollTo (const QModelIndex & index , ScrollHint hint = EnsureVisible)

重实现自 QAbstractItemView::scrollTo ().

[virtual] void QColumnView:: selectAll ()

重实现自 QAbstractItemView::selectAll ().

void QColumnView:: setColumnWidths (const QList < int > & 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.

If list contains too few values, only width of the rest of the columns will not be modified.

另请参阅 columnWidths () 和 createColumn ().

[virtual] void QColumnView:: setModel ( QAbstractItemModel * model )

重实现自 QAbstractItemView::setModel ().

void QColumnView:: setPreviewWidget ( QWidget * widget )

Sets the preview widget .

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.

另请参阅 previewWidget () 和 updatePreviewWidget ().

[virtual] void QColumnView:: setRootIndex (const QModelIndex & index )

重实现自 QAbstractItemView::setRootIndex ().

[virtual protected] void QColumnView:: setSelection (const QRect & rect , QItemSelectionModel::SelectionFlags command )

重实现自 QAbstractItemView::setSelection ().

[virtual] void QColumnView:: setSelectionModel ( QItemSelectionModel * newSelectionModel )

重实现自 QAbstractItemView::setSelectionModel ().

[virtual] QSize QColumnView:: sizeHint () const

重实现自 QWidget::sizeHint ().

[signal] void QColumnView:: updatePreviewWidget (const QModelIndex & index )

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

另请参阅 previewWidget ().

[virtual protected] int QColumnView:: verticalOffset () const

重实现自 QAbstractItemView::verticalOffset ().

[virtual] QRect QColumnView:: visualRect (const QModelIndex & index ) const

重实现自 QAbstractItemView::visualRect ().

[virtual protected] QRegion QColumnView:: visualRegionForSelection (const QItemSelection & selection ) const

重实现自 QAbstractItemView::visualRegionForSelection ().
