A FrameContainer is some graphics content (1 widget) that is surrounded by a
|
|
frame
|
|

Example:
|
|
|
|
local frame
|
|

|
|
radius = Size.radius.window,
|
|
bordersize = Size.border.window,
|
|
padding = 0,
|
|
margin = 0,
|
|
background = Blitbuffer.COLOR_WHITE,
|
|
VerticalGroup:new{
|
|
-- etc
|
|
}
|
|
}
|
|
|
|
--]]
