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))

I'm new to pyQt4 and i need to create GUI using pyQt4 and python 3.5.
I have long process which does not have exact time duration to be executed. time duration is varying according to the inputs that I use in the process at each time. There are examples about adding progress bars by using timers.but in my case i don't know the exact time duration.
I need to complete a progress bar according to the time taken by the process.as in the my code this process is methodtobeexecute(). could someone help me out to resolve this problem with a code example with a explanation. Thanks in advance....
this is my code and so far it completes the progress bar using QTimer.but what i want is complete the progress bar meanwhile the methodtobeexecute() method finishes its tasks.(QTimer has used only for check the progrss bar here)

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

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!
I have a problem with my code :/
My program needs to click a QFrame, QWidget or QGroupBox.
At the moment I use mouseReleaseEvent but it only works when my function doesn't have values set.
def testc(self,e):
print(e)
#when I use this code:
self.frame.mousePressEvent = self.testc;
#it's okey
#but when I'm using
self.frame.mousePressEvent = self.testc("ssssss");
# after starting the function automatically performs a click not working
How can I make a clicking widget, frame or group-box?

The point is that I want a group of objects in my QFrame. After clicking the QFrame I would like my program to write, after clicking.
Create a function that does not take arguments
You have to assign a function to mousePressEvent and self.testc("ssssss") does (probably) not return a function.
What you can do is to create another function
def f(self):
return self.testc("ssssss")
and assign
self.frame.mousePressEvent = self.f
For such one-liners it is often preferred to create lambda
self.frame.mousePressEvent = lambda: self.tests("ssssss")
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()

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_())
