Thanks Man, for the video series. I am re-learning pyQt5 after an 3 years break. Great stuff, easy to understand, straight to the point. Much appreciated and look forward to go through the whole series.

Bro, thank you a lot. I finally learned PyQt5 by your videos. The best tutorial ever!

[ZeNiTh_K]

Thanks man for your awesome tutorials !! Love your work . keep going !

[joevinso]

I LOVE YOU BRO, You just save my day!!!!

for the icon, the icon should be in the same folder as the .py file you are creating. if it is in a folder, the folder should also in the same path of .py file and put

Hi, I'm not getting an Icon showing in the taskbar or in the window. Does it need to be a certain size or any other requirements?

Is it not much easier to use the Qt Designer? I am using the designer since its much more easy to work with.

Hello Parwiz - Great video - curious to see how the rest of the series will be. One point that would have been helpful for me is to explain a little more why certain functions are used. self.height etc. are obvious, but why sys.exit, why sys.argv. Not sure what level of Python programmer this is aimed at but for me, I can code these up, but lack the full understanding of why we do it

A video on threading in PyQt5 would be pretty useful if you can post it, thanks.

[TheMontaseri]

Awesome. Thank you. Also could you add a bit of "why" vs just "how" in your lectures. For example, why does your Window class inherits from QMainWindow. Are you extending the class? Why isn't it a use-a relationship and is a has-a relationship. It seems to me that Window simply uses services of QMainWindow class and the rest of Qt classes. My example might be a bit loud (over-kill), but I was trying to clarify the question.


I leave you with this ... if you ever see bunch of people hovering over something and wonder who is who....the guy that says "how" does this work, is a technician, the guy that says "why" does it work, is an engineer and the guy that says "when" would this work? is a manager.

I have integrated the front end with a backend tool script. Now on the click of a button, say "Restart tool" I want the session to be the default one as if I have re ran the code to get the home GUI. How do I do the same?

[pragyas]

Hi Parwiz, The video series is just awesome . Could you please make a quick video for Mobile application development using PyQt ?? That will be really helpful.

For commercial use, do you need a qt5 licence too?

[ramshankeryadav__]

Can we print whole QFrame and component in it, to A4 paper?
Is it possible?

[arifbasri]

Do I need to install the LGPL Qt application too? from Qt website

[ivangonzalez]

Hi, I cannot see my icon in the window, is there a suggested size for the icon ? or maybe the path, I have my icon file(.png) in the same path of my .py file. Do you know what could be the problem ?

[arifbasri]

for LGPL license, I can only build app by direct coding but I cannot drag and drop widgets right? because that available only in commercial...

[jasonwell]

Bro, I want to know which plug you use show the vertical indent line or how you setup inside in the pycharm. Help me .

[abledsgaming]

Can anyone tell me at line number 7, what this line of code does "super().__init__()"

[LGTube-iy]

Sorry for the downvote, I've changed it. Can you explain the use of "sys.argv" in App = QApplication(sys.argv) and why use the sys.exit() method for the App.exec() in sys.exit(App.exec())?
