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.

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:

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

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_())

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 am new to PYQT and I am trying to get a feel for it. I am trying to populate a table widget with 5 different push buttons. I need to clear out the table between each button push, but would like to leave the headers I have. I have tried a tablewidget clearcontents. but that clears everything and I am unsure of where to place it properly so it will clear the contents before each button push, that brings in the new info.

You can use the clearContents() method when you set the table headers in an appropriate way.
change:
self.tableWidget.setItem(0,0,QtGui.QTableWidgetItem("name"))
self.tableWidget.setItem(0,1,QtGui.QTableWidgetItem("column_1"))
self.tableWidget.setItem(0,2,QtGui.QTableWidgetItem("column_2"))
self.tableWidget.setItem(0,3,QtGui.QTableWidgetItem("column_3"))
self.tableWidget.setItem(0,4,QtGui.QTableWidgetItem("column_4"))
to:
self.tableWidget.setHorizontalHeaderItem(0, QtGui.QTableWidgetItem("name"))
self.tableWidget.setHorizontalHeaderItem(1, QtGui.QTableWidgetItem("column_1"))
self.tableWidget.setHorizontalHeaderItem(2, QtGui.QTableWidgetItem("column_2"))
self.tableWidget.setHorizontalHeaderItem(3, QtGui.QTableWidgetItem("column_3"))
self.tableWidget.setHorizontalHeaderItem(4, QtGui.QTableWidgetItem("column_4"))
EDIT Extra code after comments
Maybe this helps you? I tried keeping as much of your code.
