[GEM-dev] osx fullscreen changes survey

[B. Bogart]

Hi Jamie,

Indeed lots'o' abstractions in gem would be really handy. I have not
tried Cyrille's abstraction yet, but if it includes things like the
super-handy click and drag in the gemwindow to "orbit" that would be
amazing. Looks like Cyrille did the trig to make a nice orbit using view
messages. How is the camera object going Jamie?

Actually Jamie, Id like to hear more about your kiosk project.

I think the "menubar" messages you suggest here look great. I also agree
it would be handy to have the menubar show up only when you move the
mouse to the top of the window in fullscreen mode.

I guess that could mean:

"menubar 0"
"menubar mouse" or "roll-over"?
"menubar 1"

Maybe...

"menubar 1" is the default and so you need to do "menubar 0, fullscreen
1" to lock yourself out. "fullscreen 1" on OSX will leave the menubar up?

I can't figure out if "menubar mouse" should make the menubar only show
up when the mouse is at the top, or if this should only happen when in
fullscreen mode. Seems that it makes more sense to make it consistant
and so the menubar shows up on fullscreen by default, and you need to
turn it off manually... The idea of hitting "menubar mouse" and then
nothing happens seems awkward...
