Hey! Nice tutorials. Its a pity that I didnt watch your videos before. Any plans of creating a new series based on latest Qt updates? I believe several things have changed or simplified. Also, an end to end intermediate to advanced project (please no library and bank management system!) would be really helpful. For example, an Automotive UI dashboard and, Time tracking system. Thanks!
It would be great if you had also covered how the scrollbar can send signal to line edit so scrolling the scroll bar would show its value in the line edit
First of all, congratulations for the tutorials, are amazing. My question is about the use of a global variable to change the progress bar, or maybe use the connect function with the first parameter being an ui component. I mean "connect(variable, SIGNAL(valuechange(int)), ui->progressBar,SLOT(setValue(int);" Best regards!
What you wrote in code for the signal and slot does exactly the same thing as the initial method used in the GUI of the Qt Creator. Is it not suppoesd to be more flexible than this?
Hello I'm learning from your QT tutorials I would like to know about using C ++ with QT Creator I could use Python with QT Creator Have you done or can you do tutorials on this?
Hello, when i use in video Beginners 5-QT Signal and slots, connect(ui->horizontalSlider_2,SIGNAL(valueChanged(int)),ui->progressBar_2,SLOT(setvalue(int))); it not works When i move the slider the ProgressBar not change. I think you did one step in background, but forget to it show.
Okay I'm new to Qt. I wanted to move from CLI to GUI programming for a long time now. Some questions are popping up. One of them is why are we writing the connect function in mainwindow.cpp and not in main.cpp?
The signal and slot seems quite simple and not very powerful since signal from one thing gets connected to another thing, no data transformation takes place?
Hi I have been watching your videos and learned alot. i have been trying so hard to find solution to my problem but failed. i hope you will help me. i simply want to pass value from my main form (Mainwindow2) to a dialog box when i click push button on main form to open dialog box. the value from lineedit in main foirm needs to goto lineedit in dialogbox. can you please help me. many thanks

Very useful tutorial, thank you!

thank you! very helpful :)
why we cant use ```void MainWindow::on_horizontalSlider_sliderMoved(int position)``` way to create signal and slot

Hello
I'm learning from your QT tutorials
I would like to know about using C ++ with QT Creator I could use Python with QT Creator
Have you done or can you do tutorials on this?
Would be great to update these tutorials, do you have a paid version?
he's talking slooomotion, put the video speed to x1.5 and it's like he's talking normal xD
So true lol!!
I am even at speed 2 and can understand him just fine xD
Watched this at 4x until the part i wanted to know where i still was at 2.25.
no shit, i'd rename this video to "signals and sloth".
Not so much talking so but going so slow.
Hello, when i use in video Beginners 5-QT Signal and slots, connect(ui->horizontalSlider_2,SIGNAL(valueChanged(int)),ui->progressBar_2,SLOT(setvalue(int))); it not works
When i move the slider the ProgressBar not change.
I think you did one step in background, but forget to it show.
Many thanks!
Excuse me. Can that progress bar display without slider? just random display data?
I'm working on a mac and the progress bar percentage isn't shown, how can i add it?

Okay I'm new to Qt. I wanted to move from CLI to GUI programming for a long time now. Some questions are popping up. One of them is why are we writing the connect function in mainwindow.cpp and not in main.cpp?
And couldn't we connect the button and the label the same in the previous video?
Or you could just right click the slider and choose "Go to slot..." and code the progress bar "setValue(int)" there :)
Thanks you for guide

Qt rectangle shape forming method sir
Anyone Watch 2020

how to connect different forms?
Why doesn't the progress bar go to 100%?
figured it out. the default value of the slider is 99, change it to 100.
How to use a slot "Toggled(bool)"
These codes aren't working on QTCreator 5
connect(ui->horizontalSlider,&QSlider::valueChanged,ui->progressBar,&QProgressBar::setValue);
connect / disconnect - wlacza, wylacza linki pomiedzy obiektami
good video, thank you! :-)
Ah QT too expensive for me to consider at the momment.
do you pronounce it qt or qt?
qt not qt
Can only slide to 99%
how do you fix that? help please!
TARIQLES Apparently you can use min, max values to change this, but for specifics you gotta do your own research.
