pyqt5-QListWidget

1、介绍

list组件，或者说列表组件。

2、类和初始化

class QListWidget(QListView):

快速查询：

QListWidget(parent: typing.Optional[QWidget] = None)
addItem(self, aitem: QListWidgetItem)
addItem(self, label: str)
addItems(self, labels: Iterable[str])
clear(self)
closePersistentEditor(self, item: QListWidgetItem)
count(self) -> int
currentItem(self) -> QListWidgetItem
currentRow(self) -> int
dropMimeData(self, index: int, data: QMimeData, action: Qt.DropAction) -> bool
editItem(self, item: QListWidgetItem)
findItems(self, text: str, flags: Union[Qt.MatchFlags, Qt.MatchFlag]) -> List[QListWidgetItem]
indexFromItem(self, item: QListWidgetItem) -> QModelIndex
insertItem(self, row: int, item: QListWidgetItem)
insertItem(self, row: int, label: str)
insertItems(self, row: int, labels: Iterable[str])
isPersistentEditorOpen(self, item: QListWidgetItem) -> bool
isSortingEnabled(self) -> bool
item(self, row: int) -> QListWidgetItem
itemAt(self, p: QPoint) -> QListWidgetItem
itemAt(self, ax: int, ay: int) -> QListWidgetItem
itemFromIndex(self, index: QModelIndex) -> QListWidgetItem
items(self, data: QMimeData) -> List[QListWidgetItem]
itemWidget(self, item: QListWidgetItem) -> QWidget
mimeData(self, items: Iterable[QListWidgetItem]) -> QMimeData
mimeTypes(self) -> List[str]
openPersistentEditor(self, item: QListWidgetItem)
removeItemWidget(self, aItem: QListWidgetItem)
row(self, item: QListWidgetItem) -> int
scrollToItem(self, item: QListWidgetItem, hint: QAbstractItemView.ScrollHint = QAbstractItemView.EnsureVisible)
selectedItems(self) -> List[QListWidgetItem]
setCurrentItem(self, item: QListWidgetItem)
setCurrentItem(self, item: QListWidgetItem, command: Union[QItemSelectionModel.SelectionFlags, QItemSelectionModel.SelectionFlag])
setCurrentRow(self, row: int)
setCurrentRow(self, row: int, command: Union[QItemSelectionModel.SelectionFlags, QItemSelectionModel.SelectionFlag])
setItemWidget(self, item: QListWidgetItem, widget: QWidget)
setSelectionModel(self, selectionModel: QItemSelectionModel)
setSortingEnabled(self, enable: bool)
sortItems(self, order: Qt.SortOrder = Qt.AscendingOrder)
supportedDropActions(self) -> Qt.DropActions
takeItem(self, row: int) -> QListWidgetItem
visualItemRect(self, item: QListWidgetItem) -> QRect
Return len(self).
---------------
dropEvent(self, event: QDropEvent)
event(self, e: QEvent) -> bool

3、方法

基本可以参考QComboBox组件的相关使用

4、事件
