Hello I am a student that is experimenting with GUI's and I was working in python making a simple log-in form and as I made the base layout I encountered an error where I could not solve the variables. This is the code:
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)
def main():
app = QtGui.QApplication(sys.argv)
w = Ui_Dialog(__init__)
w.show()
sys.exit(app.exec_())
class Ui_Dialog(object):
def __init__(self, parent=None):
QtGui.QMainWindow.__init__(self, parent)
self.addWidgets()
self.setupUi(self)
def setupUi(self, Dialog):
Dialog.setObjectName(_fromUtf8("Dialog"))
Dialog.resize(380, 272)
Dialog.setMinimumSize(QtCore.QSize(380, 272))
Dialog.setMaximumSize(QtCore.QSize(380, 272))
self.buttonBox = QtGui.QDialogButtonBox(Dialog)
self.buttonBox.setGeometry(QtCore.QRect(30, 240, 341, 32))
self.buttonBox.setOrientation(QtCore.Qt.Horizontal)
self.buttonBox.setStandardButtons(QtGui.QDialogButtonBox.Cancel|QtGui.QDialogButtonBox.Ok)
self.buttonBox.setCenterButtons(True)
self.buttonBox.setObjectName(_fromUtf8("buttonBox"))
self.user_name = QtGui.QTextEdit(Dialog)
self.user_name.setGeometry(QtCore.QRect(110, 50, 221, 31))
self.user_name.setAutoFillBackground(False)
self.user_name.setObjectName(_fromUtf8("user_name"))
self.user_pass = QtGui.QTextEdit(Dialog)
self.user_pass.setGeometry(QtCore.QRect(110, 120, 221, 31))
self.user_pass.setAutoFillBackground(False)
self.user_pass.setObjectName(_fromUtf8("user_pass"))
self.label = QtGui.QLabel(Dialog)
self.label.setGeometry(QtCore.QRect(20, 60, 81, 21))
self.label.setObjectName(_fromUtf8("label"))
self.label_2 = QtGui.QLabel(Dialog)
self.label_2.setGeometry(QtCore.QRect(20, 120, 81, 21))
self.label_2.setObjectName(_fromUtf8("label_2"))
self.retranslateUi(Dialog)
QtCore.QObject.connect(self.buttonBox, QtCore.SIGNAL(_fromUtf8("accepted()")), Dialog.accept)
QtCore.QObject.connect(self.buttonBox, QtCore.SIGNAL(_fromUtf8("rejected()")), Dialog.reject)
QtCore.QMetaObject.connectSlotsByName(Dialog)
def retranslateUi(self, Dialog):
Dialog.setWindowTitle(_translate("Dialog", "Dialog", None))
self.label.setText(_translate("Dialog", "USER NAME", None))
self.label_2.setText(_translate("Dialog", "PASSWORD", None))
if __name__ == "__main__":
main()
sorry if the alignment is off i am not used to having to use stack overflow but the code results in the following output:
Traceback (most recent call last):
File "C:\Users\todd7\Desktop\PY_auth\design.py", line 75, in <module>
main()
File "C:\Users\todd7\Desktop\PY_auth\design.py", line 28, in main
w = Ui_Dialog(__init__)
NameError: name '__init__' is not defined
and i am not sure how to fix the issue.
Try making your __init__ function in your Ui_Dialog class this:
def __init__(self, window, parent=None):
self.addWidgets()
self.setupUi(self)
window.show()
Then, in your main() function,
def main():
app = QtGui.QApplication(sys.argv)
w = Ui_Dialog(QtGui.QMainWindow())
sys.exit(app.exec_())

Generally when I have windows working together I will set one as the others parent or have methods for one that receives data from the other. For example:
class MainWindow(QtWidgets.QMainWindow, Ui_MainWindow):
def __init__(self):
QtWidgets.QMainWindow.__init__(self)
self.setupUi(self)
self.run_btn.clicked.connect(self.setup_project)
def setup_project(self):
self.project = ProjectParams(parent=self)
self.project.show()
if self.project.exec_() == QtWidgets.QDialog.Accepted:
self.params = self.project.params
self.loops = self.project.loops
class ProjectParams(QtWidgets.QDialog, Ui_ProjectParams):
def __init__(self, parent=None):
QtWidgets.QDialog.__init__(self, parent=parent)
self.setupUi(self)
self.buttonBox.button(QtWidgets.QDialogButtonBox.Ok).setEnabled(False)
self.params = {}
From your error I would think you need to change:
self.connect(self.pushButton, QtCore.SIGNAL('clicked()'), self.open)
to:
self.pushButton.clicked.connect(self.open)
I'm trying to connect a push-button on my main window to open a new widget when I click it. But each time I run the program I get this error:

You created a separate namespace for the ui, so you would need to access the button like this:
self.ui.gpioButton.clicked.connect(self.gpioButton_clicked)
However, if you'd prefer to have all the widgets as attributes of the window, do this:
class gpioDialog(QtGui.QDialog, Ui_GPIODialog):
def __init__(self, parent=None):
super(gpioDialog, self).__init__(parent)
flags = QtCore.Qt.Drawer | QtCore.Qt.WindowStaysOnTopHint
self.setWindowFlags(flags)

self.gpioButton.clicked.connect(self.gpioButton_clicked)

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.
It doesn't help that you've inherited object for class Ui_dialog. You should probably inherit QtGui.QDialog for that class, and rewrite your class accordingly.

I am trying open a pyqt window from another pyqt window on clicking a button but i can't really get a hold do it . Both the python files opening.py and signup.py can run standalone on their own but i can't think of a way to link them ...(Running signup.py from opening.py after clicking signup button)

The commented part in opening.py is the one creating problems . Help would be appreciated .
Your Ui_Dialog1 should inherit from QDialog, which makes it an UI object, but you inherit from object, this has no "show" method.
def handleTest1(self):
#self.accept()
#self.h=Ui_Dialog1() # You need to move this to __init__ function
#self.h.setupUi(QtGui.QDialog()) # You need to move this to __init__ function
self.h.show() # call the show method here
You need to move the self.h = Ui_Dialog1() and setupUi to init functions, this will avoid possible memory leak. (otherwise each time you click "sigunup", it will create a new object)
