In this Qt6 video we are going to talk about Qt6 Drawing Line & Text with QPainter, for this purpose we are going to use Qt6 QPainter class.

What is Qt6 QPainter ?

Qt6 QPainter is 2D painting system in the Qt6 framework, which provides a way to render graphical elements such as lines, curves and shapes in to different surface types including widgets, images and printers.

It is powerful and flexible tool for creating custom graphical interfaces and visualizations, and also supports different painting operations including basic drawing primitives such as lines, arcs and rectangles, image manipulation, gradients and transformations.

QPainter works by creating paint device which is typically a widget or an image and after that using different methods to draw on it. it uses paint engine to perform the actual rendering, which can be optimized for different platforms and hardware configurations.

Qt6 QPainter is an improvement over its predecessor, QPainter in Qt5, with better performance, more robustness and additional features. some of the new features in Qt6 QPainter include support for subpixel rendering, vector based text rendering and improved support for high DPI displays.

In result we can say that Qt6 QPainter provides developers with powerful and flexible tool for creating custom 2D graphics and interfaces in their applications. particularly in this video we want to practically learn about Qt6 Drawing Line & Text with QPainter
