QColumnView Class

成员函数

QColumnView::QColumnView(QWidget *parent = Q_NULLPTR)

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

参见 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.

参见 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.

参见 setPreviewWidget().

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

重新实现 QAbstractItemView::currentChanged().

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

重新实现 QAbstractItemView::horizontalOffset().

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

重新实现 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() and alternatingRowColors(). This can be useful when reimplementing createColumn().

This function was introduced in Qt 4.4.

参见 createColumn().

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

重新实现 QAbstractItemView::isIndexHidden().

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

重新实现 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.

参见 setPreviewWidget() and updatePreviewWidget().

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

重新实现 QWidget::resizeEvent().

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

重新实现 QAbstractItemView::rowsInserted().

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

重新实现 QAbstractScrollArea::scrollContentsBy().

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

重新实现 QAbstractItemView::scrollTo().

[virtual] void QColumnView::selectAll()

重新实现 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.

参见 columnWidths() and createColumn().

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

重新实现 QAbstractItemView::setModel().

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.

参见 previewWidget() and updatePreviewWidget().

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

重新实现 QAbstractItemView::setRootIndex().

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

重新实现 QAbstractItemView::setSelection().

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

重新实现 QAbstractItemView::setSelectionModel().

[virtual] QSize QColumnView::sizeHint() const

重新实现 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

参见 previewWidget().

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

重新实现 QAbstractItemView::verticalOffset().

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

重新实现 QAbstractItemView::visualRect().

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

重新实现 QAbstractItemView::visualRegionForSelection().
