The list component QListView is a class derived from QAbstractItemView and implements the interface defined by the QAbstractItemView class. It is one of the view classes in the Model/View architecture and a part of the Model/View framework. It provides model-based list mode or icon mode views. It displays the items stored in the model as a simple list or icon collection without parent-child hierarchy, and the view does not display horizontal or vertical titles. The common methods are as follows:
| method | describe |
| setModel() | Used to set the Model associated with the View. You can use Python's native list as the data source Model; |
| selectedItem() | Select the entry of Model; |
| isSelected() | Judge whether an entry in the Model is selected; |
| setViewMode() | Set the view mode. ListMode: items are arranged from top to bottom, and displayed in small size; IconMode: items are arranged from left to right, and displayed in large size; |
Common event types are shown in the following table:
| Event type | describe |
| clicked | This event is triggered when an item is clicked; |
| doubleClicked | This event is triggered when you double-click an item; |
| activated | This event is triggered when the item specified by index is activated; |
| entered | This event is triggered when the mouse cursor enters the item specified by index; |
| iconSizeChanged | This event is triggered when the icon size is set when the view is visible; |
| indexesMoved | This event is triggered when the index is moved in the view; |
| pressed | This event is triggered when the mouse button is pressed; |
| viewportEntered | This event is triggered when the mouse cursor enters the view. |
