For a java developer it seems that we always reuse our color variable, however **ALWAYS, WHENEVER* we create an object with ```new``` the OS reserves the memory space! So make sure to always call ```dispose()``` on system resources before allocating a new one!

Coming back to our initial problem, keeping in mind what we just learned, we need a way to get rid of our remaining resources, once the widget gets destroyed. For this purpose we register a dispose listener.
```java
// add a dispose listener
this.addDisposeListener((DisposeEvente)->{
// dispose the color of the selection
colorSelection.dispose();
});
```
During this view we store a color that we use to display the selection of text, this handler assures that this resource is not lost!
