如何访问另一个模块中的 PyQt6 中的函数

  • 772

这个最小的例子展示了如何通过切换单选按钮来激活/停用旋转框。

随着时间的推移，代码会增长并且需要分解。

帮助将方法移动spinBoxSetEnabled_1()到spinBoxSetEnabled_2()单独的文件中。

主程序

import sys

from PyQt6.QtWidgets import QMainWindow, QApplication
from PyQt6.uic import loadUi


class New(QMainWindow):
    def __init__(self):
        super(New, self).__init__()
        loadUi("Test.ui", self)

        self.RB_1.setChecked(True)
        self.RB_1.clicked.connect(self.spinBoxSetEnabled_1)
        self.SB_1.setEnabled(True)

        self.RB_2.setChecked(False)
        self.RB_2.clicked.connect(self.spinBoxSetEnabled_2)

    def spinBoxSetEnabled_1(self):
        self.SB_1.setEnabled(True)
        self.SB_2.setEnabled(False)

    def spinBoxSetEnabled_2(self):
        self.SB_1.setEnabled(False)
        self.SB_2.setEnabled(True)


if __name__ == '__main__':
    app = QApplication(sys.argv)
    window = New()
    window.show()
    sys.exit(app.exec())
