I cannot express how grateful I am for this video. I am trying to build a little word game with Qt, I once built it before on Android. And I was trying to figure out how to do what I did on Android through Qt Widgets. Now I understand I should be looking at QML for that functionality.

"And may the odds be ever in your favor!" - you made me smile right there

[andreasmusic]

Looking forward to the release of your QML for QT 6 series!

damn i've been following the videos u made in 2011 and to see that u still making videos related to qt is kind of crazy over 10 year exp.

Very good comparison. I would however disagree on QML being fast. I find it very sluggish compared to QtWidgets. And still after so many years, it is not polished at all. My recommendation would be: do you target desktop and you do not require lots of animations? Then always go with QtWidgets. If you target also mobile or embeded or require lots of animations on desktop, then go with QML.

QtWidgets are far from being dead. I would say, that QtWidgets recently became mature. While QML is still in staying in its puberty. It is definitely not mature.

Qml also is signal slot. I use to work on huge qml app for me it's faster learning curve if you get the logic. It's true most of time people use both. Qml inside widget or widget inside qml.

11:08 “view.connect(...);”

Isn’t this QObject::connect, which is static? Why is it being called on an instance?

QML is one of the most pleasant tech to work with. Not many people believes there exists a thing that building ui with it is faster then html. Qml is one of the most underrated tool in the world in my opinion

9:45 will the "wysiwyg" spit out the c code equivalent?

[harishrajora]

Is QTWidgets a better choice when you are building a software for a big company that needs to just focus on desktops and there are no relations with UI?
