Many controls share the same resources, such as images, dialog box templates and so on. A bright example is various buttons you might have in your application. Though buttons control different things, have different labels and tooltips, they do share the same graphics and behavior (that is a web-style button, a checkbox etc.).

QLIB introduces special kind of abstraction that is known as a resource. Almost each visual control needs a resource to be created before.
