Here is a simple example on how to try out the add-on component:
// Bind a ColorPicker to DTO with a string color field
binder.forField(l.colorPicker)
.withNullRepresentation(Color.WHITE)
.withConverter(new ColorToRgbaConverter("Could not convert the string to a color!"))
.bind(TestDTO::getColor, TestDTO::setColor);For a more comprehensive example, see vaadin-colorconverters-demo/src/main/java/eu/maxschuster/vaadin/colorconverters/demo/DemoUI.java
Convert a Color to RGB (eg. rgb(255,255,255)), RGBA (eg. rgba(255,255,255,1)) or HEX (eg. #ffffff)
Convert RGB (eg. rgb(255,255,255)), RGBA (eg. rgba(255,255,255,1)) and HEX (eg. #ffffff) back to a Color
