I have a python app that change mac address with pyqt5 GUI. I have two python files. The main python file (mainWindow.py) that run main program then I press button to open the second window from second python file secondWindow.py. In second python file opens a window entry then I have to put letters and numbers like then I have to pass data in the first main app label window.
Can anyone help me to solve that?
I tried to reduce code.

One solution would be to assign the MainWindow as the parent of the SecondWindow. Then to get the label text all the SecondWindow has to do is self.parent.label.setText('something'). See the minor adjustments I made below.
mainWindow.py
class Ui_MainWindow(object):
def specificWindow(self):
self.window = QtWidgets.QDialog()
self.ui = Ui_macSpecific()
self.ui.setupUi(self.window, self) # <--- assign MainWindow as parent to second window
self.window.show()
secondWindow.py
import macspoof_bash
class Ui_macSpecific(object):
def setupUi(self, macSpecific, master):
self.master = master
self.window = macSpecific
macSpecific.setObjectName("macSpecific")
macSpecific.resize(301, 140)
...
...
self.pushButton = QtWidgets.QPushButton(macSpecific, clicked = lambda: self.submit())
def submit(self):
print("submit")
text = self.lineEdit.text()
self.master.label_3.setText(text)
self.window.close()
config['ethernet']['wired_mac_address'] = text
with open("macspoof.ini", "w") as inifile:
config.write(inifile)

I have built a GUI and among other things I am using a QComboBox (drop-down menu) with three entries. I want to enable/disable some other boxes and labels in the GUI, depending on which entry is selected in the QComboBox. I have managed to do that so far.
My problem is that all changes are taken into effect only when I press the "Run" button, which executes the application.
What I want to do is the action of enabling/disabling the relevant boxes will happen once I have selected the entry from the drop-down menu and not waiting until I press the "Run" button.
Is there a way to do something like that? Can I use the focusOutEvent to check when the user has clicked anywhere else than the drop-menu and apply the changes in the other boxes/labels?
I put below the class "controlling" my GUI, but I dont post the actual class generating the GUI because it is too lengthy. If you think it is relevant I can post it. I post instead a picture of the GUI.GUI The boxes and labels in the black circles should be disabled when the "Measuring Mode" drop-box is set to "Cable loss" or "Amplifier". When it is set to "Mixer" they should be enabled. I enable/disable the boxes and labels with an if statement inside the user_input function, in the Window class. The wanted drop-down menu is represeted by the "mode_select" variable.
Edit:
I think my explanation is not very intuitive without the actual gui code so I post it below.

QComboBox uses these signals here which you can connect using signals and slots.
I think the one you would want to use is either currentTextChanged or currentIndexChanged. So you could do something like this in your init:
class Window(QtWidgets.QMainWindow):
def __init__(self):
from transfer_function_gui import Ui_MainWindow
QtWidgets.QMainWindow.__init__(self)
self.ui = Ui_MainWindow()
self.ui.setupUi(self) # setup GUI
self.ui.run_button_PM_tab.clicked.connect(self.user_input)
self.ui.freq_units_select.currentIndexChanged.connect(self.user_input)
self.ui.mode_select.currentIndexChanged.connect(self.user_input)
This will connect the event of the QComboBox changing it's selected index to a method called self.user_input.

def backBtn(self):
print("the lalala")
ui = mainWindow.Ui_MainWindow(self.MainWindow,self.loadedgreenhouses)
ui.setupUi()
self.MainWindow.show()
the event should be triggered by self.btn_back.clicked.connect(self.backBtn) but as i said it would work only in debug mode.
i tried to self.btn_back.clicked.connect(lambda : self.backBtn()) which did took me back to the main UI window but then none of the buttons in that window worked :|

How to close a QDialog
(4 answers)
Closed 1 year ago.
I've created a program that allows you to login and sign up. When you have the right credentials it opens a window but it doesn't close. The same thing happens when you press the button to sign up. I've tried to use the close method but it doesn't work i always get:
AttributeError: type object 'Ui_Dialog' has no attribute 'close'
here is the full code of all the windows:

I am new to PyQt. I want the GUI to be GUI1 from time 0 to time t1, GUI2 from time t1 to t2, ..., GUIn from time t(n-1) to t(n). So I thought I would have to use the multithreading techniques. Does anyone have available code that has the same function as my requirement?
Moreover, I met some problem when I try connect the thread's finished signal to the UpdateUI function. The code is shown below:

The file 'protocol.txt' contains the contents for each QtWidget and a timeline for when the GUI would change contents
You're using the Ui_MainWindow class incorrectly. See this answer for how to use the auto-generated UI classes.
You should be either inheriting from the UI class, or setting it as an instance attribute on one of your own classes.
class MainWIndow(QtGui.QMainWIndow,Ui_MainWindow):
def __init__(self, parent=None):
QtGui.QMainWindow.__init__(self, parent)
self.setupUi(self)
Sometimes, people won't inherit, but will assign it to an attribute of the class:
class MainWIndow(QtGui.QMainWIndow):
def __init__(self, parent=None):
QtGui.QMainWIndow.__init__(self, parent)
self.ui = Ui_MainWindow(self)
self.ui.setupUi(self)
So although nobody wants to give the answer to this question, I think I found the answer from another question asked by me in Update GUI at different time interval in QT.
I hope someone could give me the pyqt version of this answer because this is in C++.
