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)

I'm a bit new in PyQt4, I've been working on simple GUI which has an QDial and LCD Widget.I've used SIGNAL and SLOT technique,i.e when the QDial is changed it's value will be shown on the LCD Widget.
Similarly i want to print that LCD value in terminal everytime the QDial is changed.How am i supposed to do that?

You can connect own function which gets value and use print() to display it
QtCore.QObject.connect(self.dial_1, QtCore.SIGNAL(_fromUtf8("valueChanged(int)")), self.lcdNumber_1.display)
# connect own function
QtCore.QObject.connect(self.dial_1, QtCore.SIGNAL(_fromUtf8("valueChanged(int)")), self.my_function)
def my_function(self, value):
print(value)
The same with second QDial.
You can even use directly print without creating own function because print will gets value.
QtCore.QObject.connect(self.dial_1, QtCore.SIGNAL(_fromUtf8("valueChanged(int)")), print)
EDIT: as #musicamante mentioned in comment - this version
SIGNAL(..., print)
will work only in Python 3 because print in Python 2 is not function.
Or you will have to use in Python 2

sorry if the alignment is off i am not used to having to use stack overflow but the code results in the following output:

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_())
I want to open new window from existing one in pyqt.
My source code has two functions.
one functions : when button is clicked, File Dialog is opened.
another functions : when another button is clicked, New Window is
opened.
But When I want to New window, error message occurs :

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 want to open new window from existing one in pyqt.
My source code has two functions.
one functions : when button is clicked, File Dialog is opened.
another functions : when another button is clicked, New Window is
opened.
But When I want to New window, error message occurs :
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'
