Viewing pyqt4 export before adding code

Viewing pyqt4 export before adding code - python

I am new to python 3.3 and am having some trouble with random simple tasks. I made a gui in qt designer and exported the py code. I added
def show(self):
self.QtGui.show()
sys.exit(self.exec_())
and
MainWindow = Ui_MainWindow(sys.argv)
MainWindow.show()
to the end to try and view the GUI before I add in all the code. Im sure this is possible, I just can not figure it out. My entire code is:

And the error that I get is:
TypeError: object.__new__() takes no parameters
Now Im not even sure this error is related to my problem, but I am at the end of my rope trying to simply see this UI. No functionality needed yet.
Thank you in advance!

You don't need to do this by hand. pyuic4 has an option to add this: -x. Then you can just run the pyuic4 generated code and you'll see the widget. For example:
pyuic4 -x -o output.py input.ui

Using the QTextEdit widget, you access value using toPlainText().

Embedding PyQtGraph plots within an existing Qt Window

I'm trying to embed PyQtGraphs into an existing Qt Window (designed with Qt Designer and converted to .py file). I'm having trouble getting the PyQt GraphicLayoutView to size correctly to the Qt Group which is also inside a Tab.
I had previously managed to get the plots to work using MatPlotLib but they are just too slow at updating once the dataset gets larger, so i decided to make the switch to PyQtGraph as several posts suggested.
Im unsure if im embedding the plots correctly or if it is a case of resizing the GrahpicLayoutView to fill the group.
Any help is appreciated, code and images attached:

I don't see a class QMainWindowWidget in the api: http://pyqt.sourceforge.net/Docs/PyQt4/qtgui.html
Are you sure you don't mean to inherit from QMainWindow instead?

Connecting click events to function for pyqt

This is undoubtedly a simple question, but I cannot seem to get it. All i want to do is run a function on a button click. I have created a .ui and converted it to a .py file and imported it as Ui_Dialog. The gui itself opens up fine and my pushButton is called btn_browseDEM and lineEdit is called lineEdit_DEM. Help??
class MyDialog(QDialog):
def __init__(self):
QDialog.__init__(self)
# Set up the user interface from Designer.
self.ui = Ui_Dialog()
self.ui.setupUi(self)
self.ui.btn_browseDEM.clicked.connect(self.btn_browseDEM_clicked)
def btn_browseDEM_clicked(self):
self.ui.lineEdit_DEM.setText('hello')
app = QApplication(sys.argv)
window = QDialog()
gui = MyDialog()
gui.ui.setupUi(window)
window.show()
sys.exit(app.exec_())

Spawning one window from another window on button click in qt4

I've created two windows using qt4 designer, and would like to link them together. I put them both in a folder and created a file outside the directory, which I'm importing them with.
I can open both windows at the same time, but that's not what I would like to do. I would like to make it so that when a button is pushed on one window, it opens the other window, then closes the first window, so the second window is the only one left open.
This is the code for the first window, with comments next to the button that I would like to have open the other window.

I think the way to do this might be to create a function which opens the second window, then closes the first, but I'm not sure if I should put this in the file I'm using to import these two windows, or the first window.
I can hook up the buttons to a function that would normally open up the other window, but when I click on the button nothing happens.
Thanks for any help.

You really need to reconsider the design of your application.
Opening and closing multiple main windows in the manner you describe is ugly and completely unnecessary. Instead, you should have one main window and use a QStackedWidget to hold a sequence of pages that can navigated through using buttons.
To experiment with this idea, create a new main window in Qt Designer and add a QStackedWidget to it (it's in the "Containers" section). Then open the two UIs you've already designed, and copy the widgets of each UI into separate pages of the stacked-widget.
Once you've done that, make sure you give all the widgets descriptive names, because you will need to refer to them later when you start writing the logic for your program. The main script of your application should look something like this:
from PyQt4 import QtCore, QtGui
from mainwindow_ui import Ui_MainWindow
class MainWindow(QtGui.QMainWindow, Ui_MainWindow):
def __init__(self):
super(MainWindow, self).__init__()
self.setupUi(self)
...
self.buttonNext.clicked.connect(self.handleButtonNext)
self.buttonPrev.clicked.connect(self.handleButtonPrev)
def handleButtonNext(self):
index = self.stackedWidget.currentIndex() + 1
if index < self.stackedWidget.count():
self.stackedWidget.setCurrentWidget(index)
def handleButtonPrev(self):
index = self.stackedWidget.currentIndex() - 1
if index >= 0:
self.stackedWidget.setCurrentWidget(index)
if __name__ == '__main__':
import sys
app = QtGui.QApplication(sys.argv)
window = MainWindow()
window.show()
sys.exit(app.exec_())
Obviously, the real logic for your program will be more sophisticated than this, but it should give you a general idea of how to go about things.
PS:
I have never used it myself, but you might also want to see if the QWizard class might be more suitable for your needs.

Your question don't show much context but it seems you are new at PyQt and PyUIC tools.
That you post aren't (or not should be) the real windows of your app. Those class are generated for pyuic or pyuic4.
You must have something like:
class RealWindow(QMainWindow):
def __init__(parent=None):
super(RealWindow, self).__init__(parent) # Call QMainWindow constructor.
self.__ui = UI_MainWindow() # Here is when you should use that class.
self.__ui.setupUI(self) # And apply the properties to yout actual window
def on_some_button_clicked(*args, **args) # And here is where you do whatever you want to do when you press a button.
On the other hand, I'm not sure is a good idea having two main windows in the same app. I don't know even if Qt allow that at all.
I recommend you build one of your windows as a QDialog. Or build a single window with a set of controls you can hide or show at will.
I also recommend you: a pyqt tutorial

Python is a programming language that lets you work quickly and integrate systems more effectively.

Viewing pyqt4 export before adding code - python

You don't need to do this by hand. pyuic4 has an option to add this: -x. Then you can just run the pyuic4 generated code and you'll see the widget. For example: pyuic4 -x -o output.py input.ui
