pyqt 5 textEdit、line Edit操作のコード例
1.textEdit/line Editを定義します。コードのQTextEditをQLine Editに変更するだけです。
self.textEdit = QtWidgets.QTextEdit(Dialog)
self.textEdit.setGeometry(QtCore.QRect(70, 90, 171, 391))
self.textEdit.setObjectName("textEdit")
self.textEdit.setReadOnly(True)# ， textEdit ， ,
str=' '
self.textEdit.setText(str)
str=' '
self.textEdit_2.append(str)
count=10
str=str(count)
self.textEdit.setText(str)
str1 = self.textEdit.toPlainText()
#textEdit toPlainText()
#linEdit self.lineEdit.text()
