The idea is I want to separate between UI and service layer using pyQt.
I read and know that I can use a generated class from .ui by subclassing it so I don't change the layout from here.
But I don't know how to put my service, inside or outside GUI. I know only how to connect UI and method/service using slot and signals.
My service called Fan has a motor, switch and speed sensor.
Ui only has a start button, stop button, a label to display the result of self_checking and value from sensors. And before starting, Fan let say will do self-checking by running and fan and reading a sensor. All fan, motor, switch and speed sensor are QObjects.
I have difficulties applying it (service layer pattern) using pyQt5 starts with:
Where I instantiate my Fan()? I assume that I have to instantiate inside GUI class. Can I instantiate outside GUI class and connect it with GUI class with slot?
If a first page contains a progress-barr which value is added each time Fan successfully check motor, sensor and switch then: 2.1 Does it means I need to put fan.checking() in a thread to do all of this checking? and update all its results to progress bar using signal and slot?
How should I make Fan() in separate Thread meanwhile, Fan() doesn't do smth which is blocking, it only turns on, off a motor. Once motor (as hardware)is turned on, it runs until it is turned off.
Any suggestion and thought are welcomed.
many thanks...
