Virtgroup class generates special kinds of group objects whose
children can be a lot larger than the actual group. The group
acts as a (small) window through which a rectangle area of its
contents is visible.
During layout, MUI tries to place the children of a virtual
group in the visible part. If this is impossible, space is
extended as long as all children fit.
Virtual groups themselves don't offer any scrollbars to allow
user interaction. These things are handled by scrollgroup class.
Usually, you don't want to use a virtual group without a
scrollgroup.

MUIA_Virtgroup_Height V6 ..G LONG
MUIA_Virtgroup_Input V11 I.. BOOL
MUIA_Virtgroup_Left V6 ISG LONG
MUIA_Virtgroup_Top V6 ISG LONG
MUIA_Virtgroup_Width V6 ..G LONG
NAME
MUIA_Virtgroup_Height -- (V6 ) [..G], LONG
FUNCTION
Read the virtual height of a virtual group.
This attribute is quite senseless, better use
a scrollgroup object to control the virtual group.
SEE ALSO
MUIA_Virtgroup_Width, MUIA_Virtgroup_Left, MUIA_Virtgroup_Top
NAME
MUIA_Virtgroup_Input -- (V11) [I..], BOOL
FUNCTION
Specify if a virtual group should be moveable by clicking
into it and dragging the mouse. Defaults to TRUE.
NAME
MUIA_Virtgroup_Left -- (V6 ) [ISG], LONG
FUNCTION
Get/set the virtual left edge of a virtual group.
The left edge will automatically be clipped to
be between 0 and (VirtualWidth-DisplayWidth).
This attribute is quite senseless, better use
a scrollgroup object to control the virtual group.
SEE ALSO
MUIA_Virtgroup_Width, MUIA_Virtgroup_Height, MUIA_Virtgroup_Top
NAME
MUIA_Virtgroup_Top -- (V6 ) [ISG], LONG
FUNCTION
Get/set the virtual top edge of a virtual group.
The top edge will automatically be clipped to
be between 0 and (VirtualTop-DisplayTop).
This attribute is quite senseless, better use
a scrollgroup object to control the virtual group.
SEE ALSO
MUIA_Virtgroup_Width, MUIA_Virtgroup_Height, MUIA_Virtgroup_Left
NAME
MUIA_Virtgroup_Width -- (V6 ) [..G], LONG
FUNCTION
Read the virtual width of a virtual group.
This attribute is quite senseless, better use
a scrollgroup object to control the virtual group.
