s. It offers a rich set of widgets that resemble elements of native desktop applications. Built-in support for keyboard navigation, focus and tab handling and drag & drop is provided. Dimensions can be specified as static, auto-sizing, stretching, percentage, weighted flex or min/max or even as combinations of these. All widgets are based on flexible layout managers, which are instrumental to many advanced layout abilities. Interface description is done programmatically in JavaScript for enhanced performance.

(CSS). Simple appearance themes are used to style colors, icons and other visual properties; they also support runtime switching.
Object-oriented programming
qooxdoo uses a closed form to define new classes. The global class constructor takes two arguments, the name of the new class and a map that provides values for a set of predefined keys, like 'construct' (the constructor method hook), 'statics' (for static class attributes and methods), 'members' (for instance attributes and methods) and 'destruct' (for the destructor). This (possibly large) map represents the class definition. Classes can be derived from other classes using the 'extend' keyword.
The following application skeleton gives an impression of how that works. The code will create a small application with a button that features a tooltip and opens an alert box when pressed. You can also run and edit this code in an online Playground:
