Painting Code Explained

In this episode, I'm discussing some non-trivial painting code. It includes coordinate transformations, discussions of cosmetic pens and more. Links mentioned in this video: Episode 43 - coordinate transformations    • Introduction to Qt Widgets (Part 43) ...   Introduction to Qt Widgets - Module 6    • Introduction to Qt Widgets - Module 6...   Chapters: 0:00 Welcome 01:13 Starting in the UI file - layout and painting in the same widget 03:20 starting in the paintEvent method 04:50 translating to the top of the grid 06:49 scaling the painter 07:34 The rest of the paintEvent method 10:04 drawGrid method -  cosmetic pen 13:43 Its OK to paint outside the screen 15:04 The draw method - drawing a scaled pen 17:38 The drawPoint method - save/restore 20:24 drawing scaled text at a specific point 22:18 Thanks for this time The example code showcased in this video is available here: https://github.com/KDABLabs/kdabtv/tr... The video is presented by Jesper Pedersen, who started with Qt back when Qt was widgets only and the version was 1.44, which gives him 21 years of experience with Qt. Since 2000 he has taught almost 100 Qt classes, ranging from Qt Widgets to QML. Heck, Jesper even taught a few classes on QTopia Core — Trolltech's initial attempt at creating a phone stack. Today Jesper holds a fancy business title, but that doesn't prevent him from coding both in his job and in his spare time.
