The QListView class provides a list or icon view onto a model.
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.
The QListView class is one of the Model/View Classes and is part of Qt's Model/View Programming{model/view framework}.
This view does not display horizontal or vertical headers; to display a list of items with a horizontal header, use QTreeView instead.
QListView implements the interfaces defined by the QAbstractItemView class to allow it to display data provided by models derived from the QAbstractItemModel class.
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() state.
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.
The 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().

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.

which direction the items layout should flow.
If this property is LeftToRight , the items will be laid out left to right. If the 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.
Setting this property when the view is visible will cause the items to be laid out again.
By default, this property is set to TopToBottom .

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 spacing property is ignored.)

whether the items layout should wrap.
This property holds whether the layout should wrap when there is no more space in the visible area. The point at which the layout wraps depends on the flow property.

determines whether the layout of items should happen immediately or be delayed.
This property holds the layout mode for the items. When the mode is SinglePass (the default), the items are laid out all in one go. When the mode is Batched , the items are laid out in batches of 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.

whether the items can be moved freely, are snapped to a grid, or cannot be moved at all.
This property determines how the user can move the items in the view. Static means that the items can't be moved the user. Free means that the user can drag and drop the items to any position in the view. Snap means that the user can drag and drop the items, but only to the positions in a notional grid signified by the gridSize property.
Setting this property when the view is visible will cause the items to be laid out again.
By default, this property is set to Static .

whether the items are laid out again when the view is resized.
If this property is Adjust , the items will be laid out again when the view is resized. If the value is Fixed , the items will not be laid out when the view is resized.

This property is the size of the empty space that is padded around an item in the layout.

the view mode of the QListView.
This property will change the other unset properties to conform with the set view mode. QListView-specific properties that have already been set will not be changed, unless clearPropertyFlags() has been called.
Setting the view mode will enable or disable drag and drop based on the selected movement. For ListMode, the default movement is Static (drag and drop disabled); for IconMode, the default movement is Free (drag and drop enabled).

the item text word-wrapping policy
If this property is true then the item text is wrapped where necessary at word-breaks; otherwise it is not wrapped at all. This property is false by default.
Please note that even if wrapping is enabled, the cell will not be expanded to make room for the text. It will print ellipsis for text that cannot be shown, according to the view's QAbstractItemView::textElideMode.
