Hi,

found this:

"SWT widgets hold a reference to the native widget. Such references are not automatically released by the system. If you want to release an SWT widget, you have to call its dispose() method. If a container is disposed, e.g., a Shell, this container also releases all its children.

The automatic release does not work for Color, Cursor, Display, Font, GC, Image, Printer, Region, Widget and subclasses. All of these SWT objects need to be manually disposed."

I was wondering if the manual disposal is also needed to be done in RAP?

Thanks,

Sebastian

You should. It's the only way to release the resources.
If you don't dispose a control. it will stay a child of its parent.
If you don't dispose a shell it will stay a child of its display.
The objects will never get garbage collected until the display is disposed. They will continue to use memory on the server and in the browser.
