Responsive Layouts in Qt
The Problem
Qt has (almost) been here since the dawn of graphical user interfaces, being released just 5 years after Windows 3.0. Needless to say, technologies, expectations and duties for an UI toolkit evolved substantially over the years. Organizing and layouting of visual elements like buttons is one of those duties that changed significantly: From small screens with few pixels and fixed size embedded apps we came a long way to high resolution screens and handheld devices of all form factors. The changes in design philosophy are even more dramatic. Applications need to look and feel good on many devices as well as in different configurations, landscape and portrait, windowed and full screen. More than that, they need to be able to switch seamlessly between those modes.
