C++ Qt 74 - QPainter and QPen 

You can add a definition to .cpp very quickly: - Right click on a method in .h - Choose: "Refactor" > "Add Definition in dialog.cpp" P.S. The F4 key - for quick switching between .h and .cpp

I found this tutorial clear and quite enjoyable to watch. You have an excellent, soothing voice, great for tutorials! I was fuming for a while when you didn't notice the p1/p2 mistake, but it doesn't matter, you noticed it soon after anyway. Great job! Subscribed.

Hi, Brian. Great tutorials! Congrats! . Is there a way to use QPainter AND QMouseEvent? I mean, get the coordinates for QPoint using QMouseEvent? . Thanks in advance,

In production code would you actually redefine your paintpen, points, linepen etc in the paintEvent function? Seems like a lot of work wasted, because isn’t that being called on a busy loop in app.exec()? Thanks for these terrific tutorials, nearly a decade later they are still the best I can find for learning qt

VoidRealms Could you explain why you use 'this' in QPainter painter(this)? I want to know what it takes so i can make another in the main.cpp :/

Can I use QPainter out of paintEvent?

And if I want to draw inside a widget. How do I do that? Thanks for the video

Hi, I tried to daw on the label like this in qpaintevent but it fails. QPainter painter(this->ui->label); painter.setBrush(QBrush(Qt::red)); painter.drawRect(10, 10, 100, 100); Please help ..

This is amazing tutorial. Beside how to rotate text using Qpainter or using in qt??

Why we have to put "void paintEvent(QPaintEvent *e)" in dialog.h?

now i get the point. thanks (\+_+/) .

can u explain how to use OpenGL?

Brian .. Your videos are very nice. Maybe you should consider taking bitcoins as donation on your site ?

I need to make a drawing app (very simple paint), so I need to be able to let the user draw the line or other shapes just by mouse (Just as paint). I am going to watch all videos but for now, I am in a hurry to do this. Can you let me know which videos refer to related things? or even there is some related videos in this tutorial?

Hello I hope you can see this message. I followed your explannaition but I cannot see the line , and I don't understand why. if you have an email i'll send you my code but is basically exaclly like yours. SQo I don't know what is happenning. Thank you for your help

I want plus icon + for profile photo add

Selva Barathi painter.fillRect(0, 0, 100, 100, paintBrush);

"hi brian, please do my homework for me". sigh, wannabe programmers...
