1. QApplication類別對應QCoreApplication
2. @staticmethod靜態方法，不用建立實體即可以呼叫的方法
-> 回傳QCoreApplication或None

3. getOpenFileName
class QFileDialog(PySide6.QtWidgets.QDialog):
@staticmethod
def getOpenFileNames(parent: PySide6.QtWidgets.QWidget | None= ..., caption: str = ..., dir: str = ..., filter: str = ..., selectedFilter: str = ..., options: PySide6.QtWidgets.QFileDialog.Option = ...) -> typing.Tuple[typing.List[str], str]: ...
QFileDialog->QDialog->QWidget->(QObject and QPaintDevice)
QPaintDevice -> Shiboken.Object
class QDialog(PySide6.QtWidgets.QWidget):
class QWidget(PySide6.QtCore.QObject, PySide6.QtGui.QPaintDevice):
