PySide.QtGui.QListView class provides a list or icon view onto a model.
A PySide.QtGui.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 类，但使用由 Qt 模型/视图体系结构提供的方式更灵活。
PySide.QtGui.QListView class is one of the 模型/视图类 且属于 Qt 的 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 PySide.QtGui.QTreeView 代替。
PySide.QtGui.QListView implements the interfaces defined by the PySide.QtGui.QAbstractItemView 类以允许它显示提供数据，通过模型派生自 PySide.QtCore.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 PySide.QtGui.QListView.setViewMode() function, and to determine the current view mode, use PySide.QtGui.QListView.viewMode() .
Items in these views are laid out in the direction specified by the PySide.QtGui.QListView.flow() of the list view. The items may be fixed in place, or allowed to move, depending on the view's PySide.QtGui.QListView.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 PySide.QtGui.QListView.isWrapping() . This property is useful when the items are being represented by an icon view.
PySide.QtGui.QListView.resizeMode() and PySide.QtGui.QListView.layoutMode() govern how and when the items are laid out. Items are spaced according to their PySide.QtGui.QListView.spacing() , and can exist within a notional grid of size specified by PySide.QtGui.QListView.gridSize() . The items can be rendered as large or small icons depending on their PySide.QtGui.QAbstractItemView.iconSize() .

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 PySide.QtGui.QListView.uniformItemSizes() property to true.

The default value is 100.
清零 PySide.QtGui.QListView -specific property flags. See PySide.QtGui.QListView.viewMode() .
Properties inherited from PySide.QtGui.QAbstractItemView are not covered by the property flags. Specifically, PySide.QtGui.QAbstractItemView.dragEnabled() and acceptsDrops are computed by PySide.QtGui.QListView when calling PySide.QtGui.QListView.setMovement() or PySide.QtGui.QListView.setViewMode() .
| 返回类型： | PySide.QtCore.QSize |
|---|
| 返回类型： | PySide.QtGui.QListView.Flow |
|---|
This property holds which direction the items layout should flow..
若此特性为 LeftToRight , the items will be laid out left to right. If the PySide.QtGui.QListView.isWrapping() property is true, the layout will wrap when it reaches the right side of the visible area. If this property is TopToBottom , the items will be laid out from the top of the visible area, wrapping when it reaches the bottom.
设置此特性将导致项被再次布局，当视图可见时。
默认情况下，此特性被设为 TopToBottom .
| 返回类型： | PySide.QtCore.QSize |
|---|
This property holds the size of the layout grid.
This property is the size of the grid in which the items are laid out. The default is an empty size which means that there is no grid and the layout is not done in a grid. Setting this property to a non-empty size switches on the grid layout. (When a grid layout is in force the PySide.QtGui.QListView.spacing() property is ignored.)

When the mode is Batched , the items are laid out in batches of PySide.QtGui.QListView.batchSize() items, while processing events. This makes it possible to instantly view and interact with the visible items while the rest are being laid out.
