PyQt5 Lesson 5 Signals and Slots

This video introduces signals and slots so that we can now respond to events. It also wraps up our window in a class.
Here is the code for the tutorial:

thx so much, really appreciate your work.

Thankyou guy for the playlist. I wonder if you could make the editor font bigger and change the color of some keywords. For example the __init__ is displayed in violet with dark background, that make viewers hard to see what is exactly on the video.
Thankyou.

Dear Mark,
I have a problem with my code, I'm writing a GUI application with pyqt5 and I need to do some processing in order to decide to add a standarditem to a table in a window or not, all the tutorials are running functions by events, but these processes shouldn't be started with events they should run separately and add rows to the table, can you please help me. thanks

[jackohara]

Cheers for making these. Not enough solid documentation on PyQT5

Mark,
Thank you very much for the video but believe me I can not see any thing so it will be better if you can change background color of the editor.

I was just wondering about self.l and self.b, were they made as instance atts so that they can be modified from btn_clicked?

[jimmypatrick]

Can you change the font color and make them bigger I can't see half of the things!

[aspenmallery]

yes! PLEASE larger font. Also, maybe do something about your computer jet-engine fans in the background are very distracting. Thank you for publishing these tutorials.

Hey, great stuff, but I've got a quick question.
We choose to set our widgets as class members (self.l, self.b, etc).
Why don't we do the same for our layouts, e.g., self.h_box, self.v_box and so on?
Or is this a silly question? Cheers.

I would like to ask on line 28, why would the method call have no parentheses like this

[MoodSwingZX]

How about right click on certein button

[XxGabberlordxX]

Hello. I wrote the exact same code like you but my method is executed after starting the program not after hitting the button. I don't know where the mistake

[ikickss]

One more suggestion: Use a de-esser for your vocal track.

[Elxroid]

How did you run the code despite the clicked.connect issue? Did you change any inspection settings or could it be the version of PyCharm that you are using?

[albertkaderdjehaf]

Nice tutorials, but I suggest you use larger fonts. It often very hard to read.

[alanjoseph]

Hey! Nice vid! I had a question though, how does the QApplication instance know which QWidget instance to run. For eg.: how did app know to run a_window?

[DW]

i get an error saying super takes at least 1 argument

also what did the class & object achieve here ? what is the limitation of making GUI in procedural programming.

[ZenMasterScrwy]

Where was "Look at me" defined?

[RealSoundNow]

Nice videos but not the best color contrast ( for future reference )
