MUI_Scrollgroup

Scrollgroup.mui

Super class

Group.mui

Background

Scrollgroup objects can be used to supply virtual groups with scrollbars. These scrollbars automatically adjust according to the virtual and display sizes of the underlying virtual group. When scrolling is unnecessary (i.e. the virtual group is completely visible), the scrollers might get disabled or even disappear completely, depending on the users preferences settings.

MUIA_Scrollgroup_NoHorizBar -- V20 [ISG], BOOL, 0x8042cab1

FUNCTION

Don't add a horizontal scrollbar even if is would be needed.

MUIA_Scrollgroup_NoVertBar

NAME

MUIA_Scrollgroup_NoVertBar -- V20 [ISG], BOOL, 0x804264c3

FUNCTION

Don't add a vertical scrollbar even if is would be needed.

MUIA_Scrollgroup_UseWinBorder

NAME

MUIA_Scrollgroup_UseWinBorder -- V13 [I..], BOOL, 0x804284c1

FUNCTION

If you set this to TRUE, MUI will automatically make this scrollgroup controllable from gadgets in the window border. MUI will use the right border scroller if the virtual group is allowed to move vertically and the bottom border scroller if the virtual group is allowed to move horizontally.

NOTES

You must set the corresponding window attributes (see below) for your parent window to use this feature.

This attribute is not the same as MUIA_Prop_UseWinBorder. The latter one allows to specify a border directly whereas MUIA_Scrollgroup_UseWinBorder is just a BOOLEAN. MUI will decide which borders to use according to the FreeHoriz and FreeVert settings.
