Configurable event handling for user interface components

A user interface event is received by way of a user interface. A software component adapted to process the user interface event may be pushed onto a memory stack, and the user interface event may be processed using the software component on the stack, or with a software component that is not on the stack. The software component on the stack, if used, may then be popped from the memory stack. In addition, a plurality of software components may be pushed onto the memory stack, and in that case, at least one of the components may be selected to process the user interface event. The user interface event is processed using at least one of the plurality of software components, and one or more of the plurality of software components are popped from the memory stack.
