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
|
||
.itemIcon(index: int) -> QIcon
|
||
.itemText(index: int) -> str
|
||
.iconSize() -> QSize
|
||
|
||
移除条目
