How to move class method out of gui modul
-
@jsulm If there would only this method it wouldn't be a problem at all, but with a lot of them ...
Complete module will be posted here, maybe there is another way to do the same thing ... -
Ok, module "gui.py" is posted below. Also imidge of the front page of my GUI.

Picture of GUI is missing ...

Ok, this time succesed.

Just a quick note, you do realise that you are modifying a file which clearly states in its header that it can be regenerated and all your modification lost ?

Back with 3 modules. Take a look please

@California You should not move anything out of gui.py as it is auto-generated (as @SGaist already said). You should never touch auto-generated stuff.
-
@jsulm copy that. What is max size of the module to work properly?
-
@California There is no such max size. But for your own modules you should try to keep them small (not more than some hundreds of lines if possible), else it will be hard to understand them or change something. How big auto-genereated modules are doesn't matter as you should not change anything there and usually you do not want to read this code.
-
-
@California Is it really that important how big this auto-generated gui.py is?
Diagrams? See QtCharts. -
@jsulm When QTCreator is used, your code is big as my very fast. Tab controll with few pages produce plenty of lines of code ...
Ok, few words about my project.
My project involves RaspberryPi as a Master in RS485 network. This application is like a sort of SCADA for home. On the other side of the network there are slaves responsible for diferent things like temperatures, humidity, consumption of watter, electricity, ...
So Master collets those data, do some calcullations, diagrams, storing data, ... , and most important do some graphic visualisation of everything in network.
At the momment my code covers three slaves, but there are three slaves more to include into aplication. Each slave contains Microchip microcontroller PIC18F458 ...
Slaves are already in function in real situation. -
@California To keep your gui.py smaller you can create one widget for each tab in its own file (using designer, widget_1.py, widget_2.py, ...). Then add those widgets to the tabs.
-
@jsulm that would be very usefull, do you have any example of how to do it or where it could be find to look?
-
What are your skills level with python ?
-
So you know how to split your code in several logical modules/files and import them to use them ?
-
Smal change in function makes script running without an error but only "Unchecked" is printed out when radiobutton is checked or it is unchecked. How to fix this to have correct respond?
# python 2.7.9 from PyQt4 import QtCore, QtGui #from gui_1 import Ui_Form def print_situation(*args): radioButton = QtGui.QRadioButton() if radioButton.isChecked(): print "Checked" else: print "Unchecked" -
Importing functions or classes is exactly the same process.
The thing that you seem to want to do is take apart class functions
Take a look at the 3rd example from the PyQt 5 designer introduction documentation.
Basically, you have your generated file from pyuic5, then you create your own class that will use the generated code. Finally a main.py where you will instantiate your custom widget(s) and start the application.
