QComboBox 条目操作
|
|||
|
|
提供了非常多方法来创建、插入、获取条目
|
|||
|
|
|
|||
|
|
添加条目
|
|||
|
|
.addItem(text: str, user_data: QVariant = QVariant())
|
|||
|
|
.addItem(icon: QIcon, text: str, user_data: QVariant = QVariant())
|
|||
|
|
.addItems(texts: List[str])
|
|||
|
|
|
|||
|
|
插入条目
|
|||
|
|
.insertItem(index: int, text: str, user_data: QVariant = QVariant())
|
|||
|
|
.insertItem(index: int, icon: QIcon, text: str, user_data: QVariant = QVariant())
|
|||
|
|
.insertItems(index: int, list: List[str])
|
|||
|
|
|
|||
|
|
插入分割线，在原先索引位置为index的条目之前插入，注意分割线自身也算一个条目，也会增加索引值
|
|||
|
|
.insertSeparator(index: int)
|
|||
|
|
|
|||
|
|
设置条目属性
|
|||
|
|
.setItemData(index: int, value: QVariant, role:int = Qt.UserRole)
|
|||
|
|
.setItemDelegate(delegate: QAbstractItemDelegate)
|
|||
|
|
.setItemIcon(index: int, icon: QIcon)
|
|||
|
|
.setItemText(index: int, text: str)
|
|||
|
|
.setIconSize(size: QSize)
|
|||
|
|
|
|||
|
|
获取条目的属性
|
|||
|
|
.itemData(index: int, role: int = Qt.UserRole) -> QVariant
|
|||
|
|
.itemDelegate() -> QAbstractItemDelegate

.itemText(index: int) -> str
|
