Many thanks, cool tutorial for dummies like as me :)

I am beginner in qt .can you provide guidance to learn qt and make projects.

Hello, I would like to ask if anything has changed in the QT 6.8.2 version, and if so, could you create a tutorial for this version?

how to show horizontal scroll bar and scroll chart left/right?

Well this video has no audio that great because boring learning is great and if you have any important points you should write in the video I am starting GUI Applications from here.

Looks very cool and thanks for making nice informative tutorials! Btw can I use Qt C++ to interface with my mobile robot GUI (the robot uses ROS2), so I want to also make the HMI for the robot, have you done this kind of project before and is it possible to use Qt with ROS2 for Robotics?

Thank you Ketan, I gained more knowledge from your channel. I am waiting for your upcoming videos.

Very helpful! Thank you for showing everything from start to finish.

That is very cool, will you interface it as well with something?

informative

Hi Ketan, How to add QML files from Resources in CMAKE ??????

Hi Ketan, how to load QML files which are in resources ?\

great tutorial sir, you covered most of the properties and explained very well, i like it 💜

Can I know where are you learning qt from?

I have correctly linked opencv with qt, and the qt compiler too highlight in red the functions of opencv. But the moment I run it, issues say "undefined reference to _opencv functions and contrscutors_ . Could be because I didn't have release folder beside build to paste the DLL files, so I had pasted them in build/desktop_qt_6_8_1_MinGW_64_but-Debug/release . Please solve this problem, it's been 2 days I have tried solving it but nothing's seems to work.

Thanks so much for this tutorial!

Hi Thanks for your very helpful videos about qt, I learned a lot from it. I am currently working on a project, I want to display my object (which will be represented by a dot or some symbol) on Oxy coordinates in real time. If possible I would like some suggestions from you.

Hi, I able to access API key for osm but the map cannot zoom and pang ?

thanks Ketan. I am using qt 6.8 and opencv 4.10. I have done the first tutorial and everything work, I get the version, major and minor. But when I try to do the second tutorial, it crus when calling the cv::imread(" path to image") method, with minGW and with MSVC2022. Apparently it might be linked to a problem with calling the libraries. Do you have an idea what can be? Thanks

Thank You

Bro Qt ka konsa version use kr rhe ho?

You do not need to do the qcameraviewfinder.h: No such file or directory

How do i resize the column and row size to fill the white area?

i have some issue with customization on Qt 6 QML, take a look QML QQuickRectangle: The current style does not support customization of this control (property: "background" item: QQuickRectangle(0x2263c96d290, parent=0x0, geometry=0,0 0x0)). Please customize a non-native style (such as Basic, Fusion, Material, etc)

Bro am also a Qt Developer. Currently you're in working with which organisation? Your LinkedIn id?
