To construct interactive graphics such as graphical user interfaces and interactive webpages is an important matter in computer programming. For this purpose, imperative programming usually has been used. On the other hand, researchers have been attempting to apply constraint programming to interactive graphics. Furthermore, the paradigm of constraint imperative programming has been proposed. This position paper reports our ongoing work on P5CP, a new constraint imperative programming language for interactive graphics. To integrate imperative and constraint programming, we adopt the notion of events in imperative programming and the notion of guards in concurrent constraint programming. We show a simple example program in this language.
