There are several ways to create custom widgets for RAP. This article is not a guide on how to create them, but only links to the relevant resources and adds covers some current issues.

SWT-Style Custom Widgets

Those are custom widgets like they are created in SWT. There are two types: Compound widgets and Self-drawing widgets.

This guide by the creators of SWT pre-dates RAP, but is still valid for current SWT/RAP versions. The chapters about native-code can be ignored.

The current RAP developers guide covers some RAP-specific aspects of such custom-widgets.

Browser-based Custom Widgets

These widgets use HTML and JavaScript, but are not based on RAP-internals. They can be compatible with SWT applications.


The current RAP developers guide gives an overview of the techniques that can be used to create such custom widgets and links to several examples.
