I'm using pyqt4 and python 2.7.11. I have a problem with the file/directory dialogs: I don't know what to use as the parent parameter.
If I use "self" or "None", PyCharm tells me that it's expecting "QFileDialog", and it got "AppTest" and "None" instead, respectively.
If I use "parent=self" or "parent=None", PyCharm tells me that the "self" parameter is unfilled.
Please see the example code below; I'm using Qt Designer to create the ui, let me know if you need that code as well.
import sys
from PyQt4 import QtGui
import ui_test as main_frame
class AppTest(QtGui.QMainWindow, main_frame.Ui_MainAppWindow):
def __init__(self, parent=None):
super(AppTest, self).__init__(parent)
self.setupUi(self)
self.pushButton1.clicked.connect(self.dialog1)
self.show()
def dialog1(self):
file1 = str(QtGui.QFileDialog.getOpenFileName(
parent=self,
caption="Locate file 1",
directory="",
filter="Graphics files (*.jpg *.jpeg)"))
print file1
def main():
app = QtGui.QApplication(sys.argv)
gui = AppTest()
sys.exit(app.exec_())
if __name__ == "__main__":
main()
EDIT: Here's the code for the ui:

I've created a MainWindow design called Ui_Dashboard within Qt Designer. I've also created a widget called "units_table", which I'd like to import and display within the Ui_Dashboard.
I've created a new class and inherited the Ui_Dashboard class, but for some reason cannot access the verticalLayout object. See code below:

I'm able to display the imported widget perfectly fine, but I need to add it as a child to the vertical layout, which is where I'm having difficulties. Despite Ui_Dashboard being inherited, I still can't access the verticalLayout.
I keep getting the following error:
AttributeError: 'MainWindow' object has no attribute 'verticalLayout'
verticalLayout does not exist because it is created in the setupUi() method, what you must do is load it before you want to use it. Another mistake is that you should not pass self to loadUi(), since what you will do is reimplement the widget's design:
import sys
from PyQt4 import QtCore, QtGui, uic
from dashboard import Ui_Dashboard
class MainWindow(QtGui.QMainWindow, Ui_Dashboard):
def __init__(self, parent=None):
super(MainWindow, self).__init__(parent)
self.setupUi(self)
self.units_table = uic.loadUi('units_table.ui')
self.verticalLayout.addWidget(self.units_table )
if __name__ == '__main__':
app = QtGui.QApplication(sys.argv)
window = MainWindow()
window.show()
sys.exit(app.exec_())
Today I installed the PyQt4 Designer on my OpenSuse.
If I create a file, run pyuic4 test.ui > test_ui.py
it creates a new file.
Now the problem:
If I want to run the code, nothing happens. I opened it with python3 test_ui.py
The code of the test-script is:
# -*- coding: utf-8 -*-
# !/usr/bin/env python

class Ui_Form(object):
def setupUi(self, Form):
Form.setObjectName(_fromUtf8("Form"))
Form.resize(473, 316)
self.pushButton = QtGui.QPushButton(Form)
self.pushButton.setGeometry(QtCore.QRect(10, 10, 461, 301))
self.pushButton.setObjectName(_fromUtf8("pushButton"))
self.retranslateUi(Form)
QtCore.QObject.connect(self.pushButton, QtCore.SIGNAL(_fromUtf8("clicked()")), self.pushButton.close)
QtCore.QMetaObject.connectSlotsByName(Form)
def retranslateUi(self, Form):
Form.setWindowTitle(_translate("Form", "Form", None))
self.pushButton.setText(_translate("Form", "Button", None))
Other scripts like print("Hello world!") work. I think the reason is PyQt4.
Thanks for your help!

Firstly, don't edit file generated by pyuic. Make another .py file and import it. That way, instead of trying to show() the generated UI file directly, you can make a QMainWindow based class that you can run show() on and it will build the generated ui file for you. Like this:
import sys
from PyQt4 import QtCore, QtGui
from Ui_Form import Ui_Form
class Main(QtGui.QMainWindow):
def __init__(self):
super(Main, self).__init__()
# build ui
self.ui = Ui_Form()
self.ui.setupUi(self)
# connect signals
self.ui.some_button.connect(self.on_button)
def on_button(self):
print 'Button clicked!'
if __name__ == '__main__':
app = QtGui.QApplication(sys.argv)
main = Main()
main.show()
sys.exit(app.exec_())
These are my first steps in Qt. I'm trying to build simple text editor like in this tutorial: http://www.rkblog.rk.edu.pl/w/p/simple-text-editor-pyqt4/
So, I've created the design in Qt Designer. Here's the preview:
Perfect :)
Here are Qt Objects and Classes to make it clear how the layout is built:
I've compiled the .py file:

simpleTextEditor.setWindowTitle(_translate("simpleTextEditor", "Simple Text Editor", None))
self.buttonOpen.setText(_translate("simpleTextEditor", "Open", None))
self.buttonClose.setText(_translate("simpleTextEditor", "Close", None))
And created my very simple app:
import sys
from PyQt4 import QtCore, QtGui
from simpleTextEditor_gui import Ui_simpleTextEditor
class StartQT4(QtGui.QMainWindow):
def __init__(self, parent=None):
QtGui.QWidget.__init__(self, parent)
self.ui = Ui_simpleTextEditor()
self.ui.setupUi(self)
# tutaj dajemy wlasne polaczenia slotow
QtCore.QObject.connect(self.ui.buttonOpen,QtCore.SIGNAL("clicked()"), self.file_dialog)
def file_dialog(self):
fd = QtGui.QFileDialog(self)
self.filename = fd.getOpenFileName()
from os.path import isfile
if isfile(self.filename):
text = open(self.filename).read()
self.ui.editorWindow.setText(text)
if __name__ == "__main__":
app = QtGui.QApplication(sys.argv)
myapp = StartQT4()
myapp.show()
sys.exit(app.exec_())
Now when I run the app, all the objects are stacked, which looks like this:
Any help appreciated!
The main problem with your code is that you are using the wrong base-class for your StartQT4 subclass. It should match the top-level class from Qt Designer, which is a QDialog.
You can also simplify your code a little, by adding the ui directly to your sub-class, and by using new-style signal and slot syntax.
With these changes in place, your code would look like this:
import sys
from PyQt4 import QtCore, QtGui
from simpleTextEditor_gui import Ui_simpleTextEditor
class StartQT4(QtGui.QDialog, Ui_simpleTextEditor):
def __init__(self, parent=None):
QtGui.QDialog.__init__(self, parent)
self.setupUi(self)
# tutaj dajemy wlasne polaczenia slotow
self.buttonOpen.clicked.connect(self.file_dialog)
def file_dialog(self):
fd = QtGui.QFileDialog(self)
self.filename = fd.getOpenFileName()
from os.path import isfile
if isfile(self.filename):
text = open(self.filename).read()
self.editorWindow.setText(text)
if __name__ == "__main__":
app = QtGui.QApplication(sys.argv)
myapp = StartQT4()
myapp.show()
sys.exit(app.exec_())
I am a python and qt-designer newbie user. I have made a simple python code for random generating numbers. Now what i want is when i click a button the output will be on GUI and not on terminal. So far i have managed to click a button and the output will be generated in terminal but that is not what i want.
So here is the qt GUI which i have made in QT-designer with no modification as to script. Thanks for any help!

I think I understand your question, but I'm not entirely certain. Anyway, I think what you want to do is something like this. First, instead of clearing the label, replace it with something like:
QtCore.QObject.connect([...], self.button_clicked)
Now, you need to create that function in your class:
def button_clicked(self):
x = 100 # Generate your number here
self.label.setText("My number: {0}".format(x))
