QLabel 标签控件
|
|||
|
|
|
|||
|
|
标签控件用于在界面上显示文字、图像等
|
|||
|
|
官方文档：https://doc.qt.io/qtforpython/PySide6/QtWidgets/QLabel.html
|
|||
|
|
继承自 QFrame
|
|||
|
|
|
|||
|
|
有两种构造函数，可以传入文本、父控件、Qt.WindowFlags(一般不用)三个参数：
|
|||
|
|
__init__(self, parent: Optional[QtWidgets.QWidget] = None, f: Qt.WindowFlags = Default(Qt.WindowFlags))
|
|||
|
|
__init__(self, text: str, parent: Optional[QtWidgets.QWidget] = None, f: Qt.WindowFlags = Default(Qt.WindowFlags))
|
|||
|
|
|
|||
|
|
QLabel的大小会根据其内容自动调整，也可以手动指定
