Programming with Qt Quick 2/6 - Meet Qt Quick Part 2
summary
Shows that QML gradients often fall back to slow software rendering (X‑render on some NVIDIA drivers) and so recommends pre-render PNGs for embedded targets; demonstrates button UI built from rectangles with images and text, anchored layouts, rounded corners via radius, and a mouse area that fills the button for clicks. Explains surprising gotcha that anchors only bind to parent/siblings and can produce zero sizes without fixed constraints, and covers keyboard handling with keys.onPressed and focus delegation with focusScope.
