Is it impossible to create a touch keyboard in a new frame? If so, in what way?
It depends on what you are trying to implement. It may be beneficial to check out the coordinate map example to see how you can use the touchevent to accomplish a keyboard type of functionality.
If the JComponent you want to attach a (default UR touch keyboard) to, is a child within the parent JPanel in your View-class, it is possible to tie this keyboard tot hat component.
It is generally not possible to tie a UR supplied keyboard, to an overlay outside of the bounds of the View-JPanel.
