extends group

Default image for contract group button.
• parameter DEFAULTENCLOSINGCLASS = "dragGroup";
Subclasses can set this to change default css class for a group.
• parameter DEFAULTEXPANDIMAGE = "images/grayDragExpand.png";
Default image for expand group button.
• parameter DEFAULTHEADERLAYOUT = "ITFC";

Default image for maximize group button.

• property centerHeader
as %ZEN.Datatype.boolean [ InitialExpression = 0 ];
If set, this boolean flag indicates that the title section of the header
should be centered over the dragGroup
• property colSpan
as %ZEN.Datatype.integer [ InitialExpression = 1 ];
If used as a child of a snapGroup, this specifies the (initial static) width of the widget
in columns
• property header
as %ZEN.Datatype.caption [ InitialExpression = "Untitled Group" ];
Title to display in header section for this group.
• property headerLayout
as %ZEN.Datatype.string [ InitialExpression = ..#DEFAULTHEADERLAYOUT ];
The header layout pattern determines the order in which control windows are added
to the header section of the dragGroup window frame. This is encoded as a five
character string consisting of the following tokens
'I' represents the Iconify button
'T' represents the Title section with both application logo and header caption
'F' represents the Full screen button
'C' represents the Close button
'U' represents the User content div (if desired)
This string allows one to restructure the location of the controls with a single
call and might be useful if the page designer is trying to match the look and feel
of a given operating system. For example, MS-Windows systems follow the pattern of
'TIFC' whereas MacOS adopts the standard of CIFT with the title centered
(cf. centerHeader) The Title section represent something of a breakpoint in the header
layout. Everything prior to the header floats from the left end of the header;
Everything after the header, floats from the right end.
