AttributeError:'ui_form'对象没有属性'printham_btn'
题
我开始使用qt 4.8.6学习qtdesigner(python),我遵循本教程:
https://www.youtube.com/watch?v=glqrzliiw2e
但它显示给我有时标题中有时有时attributeError:'ui_form'对象没有属性'printham_btn'。有人可以告诉我我要做什么或修复我的代码。
谢谢!
我知道这个论坛的帖子已经发布,但我找不到我在案件中要做的事情。
代码:
from PyQt4 import QtCore, QtGui
import sys
try:
_fromUtf8 = QtCore.QString.fromUtf8
except AttributeError:
def _fromUtf8(s):
return s
try:
_encoding = QtGui.QApplication.UnicodeUTF8
def _translate(context, text, disambig):
return QtGui.QApplication.translate(context, text, disambig, _encoding)
except AttributeError:
def _translate(context, text, disambig):
return QtGui.QApplication.translate(context, text, disambig)
class Ui_Form(QtGui.QWidget):
def __init__(self):
QtGui.QWidget.__init__(self)
self.setupUi(self)
def setupUi(self, Form):
Form.setObjectName(_fromUtf8("Form"))
Form.resize(400, 300)
self.verticalLayout_2 = QtGui.QVBoxLayout(Form)
self.verticalLayout_2.setObjectName(_fromUtf8("verticalLayout_2"))
self.verticalLayout = QtGui.QVBoxLayout()
self.verticalLayout.setObjectName(_fromUtf8("verticalLayout"))
self.print_ham = QtGui.QPushButton(Form)
self.print_ham.setObjectName(_fromUtf8("print_ham"))
self.verticalLayout.addWidget(self.print_ham)
self.verticalLayout_2.addLayout(self.verticalLayout)
self.retranslateUi(Form)
QtCore.QMetaObject.connectSlotsByName(Form)
def retranslateUi(self, Form):
Form.setWindowTitle(_translate("Form", "Super ham", None))
self.print_ham.setText(_translate("Form", "print ham", None))
self.printHam_btn.clicked.connect(self.printHam)
def printHam(self):
print('Ham!')
if __name__ == "__main__":
app = QtGui.QApplication(sys.argv)
main_window = Ui_Form()
main_window.show()
sys.exit(app.exec_())
. 解决方案
问题在这里:
self.printHam_btn.clicked.connect(self.printHam)
.
您可以不同地调用QPushButton实例,因此您需要将此行更改为:
self.print_ham.clicked.connect(self.printHam)
