pyqt5和qtdesign的使用

发现我的使用时候有点跟他不同.

我是

from PyQt5 import QtCore, QtGui, QtWidgets
from PyQt5.QtCore import *
from PyQt5.QtWidgets import * 
class Ui_Dialog(object):
    def setupUi(self, Dialog):
        Dialog.setObjectName("Dialog")
        Dialog.resize(813, 703)
        self.textEdit = QtWidgets.QTextEdit(Dialog)
        self.textEdit.setGeometry(QtCore.QRect(80, 120, 671, 421))
        self.textEdit.setObjectName("textEdit")

        self.retranslateUi(Dialog)
        QtCore.QMetaObject.connectSlotsByName(Dialog)
        Dialog.show()
    def retranslateUi(self, Dialog):
        _translate = QtCore.QCoreApplication.translate
        Dialog.setWindowTitle(_translate("Dialog", "Dialog"))
if __name__ == "__main__":
    import sys
    app = QApplication(sys.argv)
    widget = QWidget(None)
    Ui_Dialog().setupUi(widget)
    sys.exit(app.exec_())
    pass

也就是第五步从1.py进行修改:1.在setupUi里面最后一行写的是Dialog.show()  2.最后贴上 

if __name__ == "__main__":
    import sys
    app = QApplication(sys.argv)
    widget = QWidget(None)
    Ui_Dialog().setupUi(widget)
    sys.exit(app.exec_())
    pass

就可以了.

原因就是qtdesingner不给写这个class的show,也缺少if main这些东西,然后实例化的时候需要自己看着改,我这里的class是

Ui_Dialog.所以倒数第三行是他加()
