deprecatedclass %ZEN.Component.abstractDragGroupMgr
extends activeGroup
%ZEN.Component.abstractDragGroupMgr
This is a parent class to house common functionality for all of the activeGroups
that are expected to have instances of DragGroup as their only immediate children
• parameter DEFAULTENCLOSINGCLASS = "activeGroup";
To be compatible with the static layout manager the enclosing class
has to be the generic activeGroup rather than the specific type of
dragGroup manager such as desktopGroup.
The desktopGroup (et al.) is the one used for tuning attributes of
the absolutely positioned elements.
• parameter INCLUDEFILES = "zenCSLM.js";
CSV list of additional include files (either .js or .css) that
should be included when this component is used on a page.
By default, the file extension (.js or .css) is used to determine whether an
item in the list is a script include or a style include. You can override
this behavior by adding the terms "script:" or "style:" to the beginning of
the file name or names. This prefix is not used as part of the include filename.
• property groupName
as %ZEN.Datatype.string [ InitialExpression = "dragMgr" ];
The logical name of the manager with respect to the external JavaScript
code that actually manages the space
• method %DrawHTML()
Static HTML display method: draw the BODY of this component
as HTML.
Subclasses implement this in order to render the static HTML
contents of a component.
• method bringToFront(dragGroup)
[ Language = javascript ]
Programmatically give the "focus" to the given drag group
• method broadcast(signal, value)
[ Language = javascript ]
Send one of several predefined signals to each of the active DragGroup windows associated
with this group. Valid signals to pass include:
"resize" - call the onresize handler (if any) for each window
"disableCoverplate" - hide the event trapper coverplate from all windows
"disableResize" - remove the resize pip from the lower right corners of the windows
"disableMaxToggle" - reset mouse clicks on the header to the default (drag) behavior
"enableCoverplate" - force an invisible event trapper to cover the window to prevent contents from seeing events
"enableMaxToggle" - redefine the window header to be a maximize button rather than a drag handle
"enableResize" - restore the resize pip to the lower right corners of the windows
"removeDragHeader" - completely hide the drag handle and resize the window to use the recovered space
"restoreDragHeader" - restore the drag handle and resize the window to account for the newly used space
"setBodyStyle" - given a JSON representation of a style object in value, add the given rules to the existing style of the drag body
"setHeaderStyle" - given a JSON representation of a style object in value, add the given rules to the existing style of the drag header
"setHeaderLayout" - set the headerLayout property of all children to the given value
"processAppMessage" - simply pass the value given to the dragGroup children, subclasses of dragGroup
can override the default processAppMessage() method to extend the broadcast facility to address
application specific signals
• method forceRefresh()
[ Language = javascript ]

• method getGroupManager()
[ Language = javascript ]

• method getWallpaperDiv()

• method onloadHandler()

reinitialize this on page load.
• method setProperty(property, value, value2)
[ Language = javascript ]
