点击按钮，最小化PyQt5应用程序-Java 学习之路

我找到了一些关于如何最小化pyqt小部件到系统托盘的材料，但我没有找到我需要的东西 .

我想在按钮点击时最小化窗口小部件，我不想覆盖默认关闭按钮，当人们点击窗口边框关闭时，它仍然会关闭，但是当它点击我的按钮时，它将最小化到系统托盘 .

这是否可能，因为所有示例都尝试覆盖默认事件 . 我附加的这个代码是在qtDesigner中创建的，它只有一个按钮，有点像游乐场，我希望有人可以帮忙，干杯 .

Qt Designer创建一个用于填充另一个窗口小部件的类，它不是窗口小部件，因此建议创建一个继承自相应窗口小部件并使用Ui_Form类填充的类 . 有关更多信息，请阅读以下内容

http://pyqt.sourceforge.net/Docs/PyQt5/designer.html

说到这一点，您必须使用 showMinimized() 方法 .

        self.btn_name.setText(_translate("Form", "PushButton"))

class Form(QtWidgets.QWidget, Ui_Form):
    def __init__(self, *args, **kwargs):
        QtWidgets.QWidget.__init__(self, *args, **kwargs)
        self.setupUi(self)
        self.btn_name.clicked.connect(self.minimize)

    def minimize(self):
        self.showMinimized()

if __name__ == "__main__":
    import sys
    app = QtWidgets.QApplication(sys.argv)
    w = Form()
    w.show()
    sys.exit(app.exec_())
