In modern UI’s you can often find round avatar images like shown in this image:
Creating these special UI nodes with JavaFX isn’t that hard. The most important JavaFX features to create such a rounded image is clipping. By using clipping you can define the area in that a control can draw it’s content. A clip can be any shape and you only need to set the shape property of a JavaFX Node instance to define its clipping. You can find an additional clipping description here.
Let’s start creating the component. As a first step we will define a Circle shape as a clip and define it for an ImageView instance:
In addition a border should be added to the component. To do so we add one (or several) Circle shapes on top of the ImageView:
In the JavaFX code you can simply bind the bounds of the image to the bounds of the clip and the circle instances that are used as a border.
