My source code has two functions. 我的源代码有两个功能。
But When I want to New window, error message occurs : 但是,当我要到新窗口时,会出现错误消息:
Traceback (most recent call last): File "C:\\Users\\Han\\Desktop\\project\\prototype\\newwindow.py", line 61, in check_start self.w.show() AttributeError: 'Ui_dialog' object has no attribute 'show' 追溯(最近一次通话):文件“ C:\\ Users \\ Han \\ Desktop \\ project \\ prototype \\ newwindow.py”,行61,位于check_start self.w.show()中AttributeError:'Ui_dialog'对象没有属性'节目'

import sys
app = QtGui.QApplication(sys.argv)
Form = QtGui.QWidget()
ui = Ui_Form()
ui.setupUi(Form)
Form.show()
sys.exit(app.exec_())
The line self.w.show
, where you've declared w
as a Ui_dialog
object, will attempt to call the show
instance variable inside Ui_dialog
, which doesn't work because you've never defined any function called show
. 在
self.w.show
行中,您已将w
声明为Ui_dialog
对象,该行将尝试在Ui_dialog
内部调用show
实例变量,该变量Ui_dialog
,因为您从未定义过任何称为show
函数。
It doesn't help that you've inherited object
for class Ui_dialog
. 您已经继承了类
Ui_dialog
object
,这Ui_dialog
。 You should probably inherit QtGui.QDialog
for that class, and rewrite your class accordingly. 您可能应该继承
QtGui.QDialog
,并相应地重写您的类。
