详细描述

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 模型/视图类且属于 Qt 的模型/视图框架 .

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

方法文档编制

QColumnView.init ( self , QWidget parent = None)

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 () 来设置模型。

list-of-int QColumnView.columnWidths ( self )

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

另请参阅 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.

QColumnView.currentChanged ( self , QModelIndex current , QModelIndex 上一 )

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

重实现自 QAbstractItemView.currentChanged ().

int QColumnView.horizontalOffset ( self )

重实现自 QAbstractItemView.horizontalOffset ().

QModelIndex QColumnView.indexAt ( self , QPoint point )

重实现自 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 () 和 alternatingRowColors (). This can be useful when reimplementing createColumn ().

该函数在 Qt 4.4 引入。
