Nah, this is the perfect place to post picogui questions :)

There are three type of "root widgets" your application can have
currently:
- Normal application, with a 'panelbar' for resizing
- Toolbar application, that will always stick to the edge of the
screen
- Popups, which are always modal and exist in their own layer above
normal applications
When the app calls pgRegisterApp(PG_NORMAL_APP,"Foo",0) it creates a
panel widget to house the application, which has the bar showing the
app's name. If you want a truly fullscreen app, you could create a
popup using pgNewPopup(), pgNewPopupAt(), or pgDialogBox(). However,
creating a fullscreen popup is generally a rude thing to do as other
applications don't get a chance to use the display at all. The best
thing to do would be write a normal application, then disable the
panelbar. You can do this in pgserver's compile-time options, or you
can do it in the theme by setting the panelbar object's 'width'
property to zero.

If you want the app title, just at the top of the screen, try setting
your app to stick to the bottom of the screen rather than the default
of sticking to the top. Right after your pgRegisterApp, call:
pgSetWidget(PGDEFAULT, PG_WP_SIDE, PG_S_BOTTOM, 0);

this is a known bug in the scrollbar. We'll fix it soon i hope :)
