LayoutChange Enumeration

This enumerates the reasons that a layout may no longer be valid when a particular Northwoods.GoXam.Part has been added or removed.

Syntax

[TypeConverter(Northwoods.GoXam.Layout.LayoutChangeConverter)]
[Flags()]
public enum LayoutChange : System.Enum

Members

Member	Description
Added	A node, link, or group membership has been added.
All	All LayoutChange flags combined together, except for InitialOnly. Caution: due to the likelihood of frequent layouts, this is basically only used to indicate to Invalidate that a new layout should be performed unconditionally.
DiagramLayoutChanged	The Layout property value has been replaced. There is no Northwoods.GoXam.Part associated with this change.
GroupLayoutChanged	The Layout property value has been replaced on a group.
GroupSizeChanged	The size of a group has changed.
InitialOnly	When this flag is included in the DiagramLayout.Conditions, no layouts will occur after the initial one, unless the layout is invalidated unconditionally.
LinkAdded	A link has been added to the diagram.
LinkRemoved	A link has been removed from the diagram.
MemberAdded	A member node has been added to a group.
MemberRemoved	A member node has been removed from a group.
NodeAdded	A node has been added to the diagram.
NodeLocationChanged	The location of a node or group has changed. Caution: this is rarely used, due to the likelihood of frequent layouts.
NodeRemoved	A node has been removed from the diagram.
NodeSizeChanged	The size of a node (that is not a group) has changed. Caution: this is uncommonly used, due to the likelihood of frequent layouts.
None	No particular reason for an layout invalidation.
Removed	A node, link, or group membership has been removed.
Standard	All of the Added and Removed flags, plus DiagramLayoutChanged and GroupLayoutChanged, but not NodeSizeChanged and NodeLocationChanged and InitialOnly. This is the default value of DiagramLayout.Conditions. It corresponds to all of the graph-structural changes and layout replacements.
ViewportSizeChanged	The size of the ViewportBounds has changed, either because the Northwoods.GoXam.DiagramPanel has changed size or because the Scale has changed. This only applies to the top-level layout, the Layout.
VisibleChanged	The Visible property has changed on a node or a link.

Remarks

These flags values may be combined to provide the DiagramLayout.Conditions under which a DiagramLayout may be invalidated.

You can combine these values in XAML too -- just say: <go:TreeLayout Conditions="NodeAdded LinkAdded" ... />
