Started to work on applet undocking for my Ultrastudio.org.
Many applets we have work nicely with various dimensions and
pulling them out if preferred seems increasingly attractive
idea. Oracle's JRE even has some native undocking
capabilities but it is rather cryptic, goes through some
get this working with IceTea. Seems better to add a couple
of classes to the applet jar and have full control.
It is surprisingly simple to undock the applet: the code
that does this simply removes it from some mysterious
container where it is attached on a browser and then is free
to place it into trivial JFrame. It is even possible to
reattach the applet to its browser container when the user
closes this JFrame (inside the window listener).
It is more difficult to implement support, how to signal
that we want to undock the applet. Oracle talks something
about dragging out with ALT key pressed but with my IceTea
seems not working very well - I can register mouse listener
on applet but majority of mouse exit events do not get
delivered. Adding a button into JLayeredPane seems more
promising: inside this pane, the button is nicely over the
rest of the applet, exactly in location I can set with
setBounds(...) and reacts to mouse click, calling my action
listener. The new problem is that the button is covering
part of the applet interface; thinking that to do now. Maybe
the button can be auto-hidded after several seconds of run.
