详细描述 ¶

A QListView presents items stored in a model, either as a simple non-hierarchical list, or as a collection of icons. This class is used to provide lists and icon views that were previously provided by the QListBox and QIconView classes, but using the more flexible approach provided by Qt’s model/view architecture.

QListView class is one of the 模型/视图类 and is part of Qt’s 模型/视图框架 .

此视图不显示水平或垂直标题；要显示具有水平标题的项列表，使用 QTreeView 代替。

QListView 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。

Items in a list view can be displayed using one of two view modes: In ListMode , the items are displayed in the form of a simple list; in IconMode , the list view takes the form of an icon view in which the items are displayed with icons like files in a file manager. By default, the list view is in ListMode . To change the view mode, use the setViewMode() function, and to determine the current view mode, use viewMode() .

Items in these views are laid out in the direction specified by the flow() of the list view. The items may be fixed in place, or allowed to move, depending on the view’s movement() 状态。

If the items in the model cannot be completely laid out in the direction of flow, they can be wrapped at the boundary of the view widget; this depends on isWrapping() . This property is useful when the items are being represented by an icon view.

resizeMode() and layoutMode() govern how and when the items are laid out. Items are spaced according to their spacing() , and can exist within a notional grid of size specified by gridSize() . The items can be rendered as large or small icons depending on their iconSize() .

改善性能 ¶

It is possible to give the view hints about the data it is handling in order to improve its performance when displaying large numbers of items. One approach that can be taken for views that are intended to display items with equal sizes is to set the uniformItemSizes property to true.
