I’m trying to learn how to use QThreads in a PyQt Gui application. I have stuff that runs for a while, with (usually) points where I could update a Gui, but I would like to split the main work out to its own thread (sometimes stuff gets stuck, and it would be nice to eventually have a cancel/try again button, which obviously doesn’t work if the Gui is frozen because the Main Loop is blocked).
I’m trying to show an opencv image with a QLabel. I got two different versions of the image, first one is the opencv BGR image, the second one is the RGB image using image[:,:,::-1], the BGR version works fine but the RGB version doesn’t work.
I’m using QtWebEngineWidgets, QtWebChannel to create PyQt5 application, which uses HTML, CSS, JavaScript.

I am using PyQt4, and I am trying to create a collapsible box where it will contains a couple of child widgets where the child widgets are already created and layout using a QVboxLayout
My code was created with PyQt4 and I want to convert it to PyQt5.
I have tried some scripts to convert the code; but, nothing changed except the name.
What do I need to change manually in order to make the code work with PyQt5?
How could I customize the Title Bar (including: close, maximize, minimize buttons, title) and the Frame of desktop application written in PyQt so that it looks like the below image?. I need a way to specify the colors I want to use for title bar elements (buttons, text title and background-color of bar and buttons). 
I’m just getting started with PyQt5. I have been trying to accomplish a seemingly very simple task but haven’t been able to get enough info about it.
