No.
You have needs, but they're definitely not "these methods".
I suspect that your needs are more about knowing when a popup panel (or
dialog box, or menu), and any such popup panel, is shown/hidden.
Let's face the truth: hacking into PopupImpl wasn't a good idea; internals
can change, and in this case they did.
What you need is to make sure that you attach an AttachHandler and maybe a
CloseHandler to each popup that you need to "monitor" that way; or maybe
make sure every popup panel uses your own subclass that overrides the
show() and hide() methods.
Put differently: GWT does not support "aspect oriented programming" of any
form; things have to be explicit, and abstraction layers built upon it if
you want to hide them from your code.
It has worked for you hacking into the popup panel internals; but "Impl"
classes (and "impl" packages) are implementation details where things exist
for a purpose (which is not that you use them as hooks to plug your own
logic), and can change at any time without notice; and it happened in 2.7.
