LayoutManager

LayoutManager

public LayoutManager()

layoutManager = LayoutManager()

The constructor for the standard layout manager that is the initial value of LayoutManager.

Animated

public bool Animated { get; set; }

value = layoutManager.Animated
layoutManager.Animated = value

Gets or sets whether there should be animated motion moving the nodes from their current positions to their laid out positions.

AnimationDisablesDiagram

public bool AnimationDisablesDiagram { get; set; }

value = layoutManager.AnimationDisablesDiagram
layoutManager.AnimationDisablesDiagram = value

Gets or sets whether the Diagram is disabled during a layout animation.

AnimationTime

public int AnimationTime { get; set; }

value = layoutManager.AnimationTime
layoutManager.AnimationTime = value

Gets or sets the time in milliseconds that any animation should take.

DefaultLocation

public Point DefaultLocation { get; set; }

value = layoutManager.DefaultLocation
layoutManager.DefaultLocation = value

Gets or sets the location from which unpositioned nodes appear at the start of the animation.

Diagram

public Diagram Diagram { get; internal set; }

value = layoutManager.Diagram
layoutManager.Diagram = value

Gets the Diagram for which this LayoutManager performs automatic layouts.

Initial

public LayoutInitial Initial { get; set; }

value = layoutManager.Initial
layoutManager.Initial = value

Gets or sets under what conditions an "initialization" or "reset" of the model should cause layouts to be invalidated.

SkipsInvalidate

public bool SkipsInvalidate { get; set; }

value = layoutManager.SkipsInvalidate
layoutManager.SkipsInvalidate = value

Gets or sets whether LayoutChange) should do nothing when a part is added/removed/changed.

CanLayoutPart

public virtual bool CanLayoutPart(Part p, IDiagramLayout lay)

result = layoutManager.CanLayoutPart(p, lay)

This predicate decides whether a Part should participate in an IDiagramLayout's layout.

p

a Node or Link

lay

the layout that might be responsible for positioning the part

Returns: True if the part is visible and if the part's LayoutId is not "None" and is either "All" or the same value as the layout's Id. False for all Adornments and for all Nodes that are IsLinkLabel, and for all Groups that have no Layout.

InvalidateLayout

public virtual void InvalidateLayout(Part p, LayoutChange change)

layoutManager.InvalidateLayout(p, change)

Declare that the IDiagramLayout including a given Part is now invalid and may need to be performed again soon.

p

must be a Part

change

a hint on the reason for the need for a new layout; this is used to decide whether a layout is really needed.

LayoutDiagram

public virtual void LayoutDiagram(LayoutInitial init, bool immediate)

layoutManager.LayoutDiagram(init, immediate)

Request a re-layout of all invalidated layouts in this diagram.

init

If the value is InvalidateAll, all IDiagramLayouts will be declared invalid, and they will all be performed at the time given by the argument. If the value is InvalidateIfNodesUnlocated, IDiagramLayouts will be declared invalid only if they are responsible for Nodes that do not have a Location, because their X and/or Y values are Double.NaN. If the value is ValidateAll, all IDiagramLayouts will be declared valid, and no layout will occur until after something else happens to invalidate a layout. If the value is None, no layout validity is changed -- any invalid layouts will be performed at the specified time.

immediate

If true this method performs an immediate layout. If false this method schedules a layout to occur soon.

LayoutDiagram

public void LayoutDiagram()

layoutManager.LayoutDiagram()

Request a re-layout of all of the nodes and links in this diagram.

MoveAnimated

public void MoveAnimated(Node node, Point newpos)

layoutManager.MoveAnimated(node, newpos)

This basically just sets the value of Position, but with animated movement.

node

newpos

a new position in model coordinates

PerformLayout

protected virtual void PerformLayout()

layoutManager.PerformLayout()

This method is called asynchronously in order to layout a Diagram.

AnimatedProperty

public static readonly DependencyProperty AnimatedProperty

value = LayoutManager.AnimatedProperty

Identifies the Animated dependency property.

AnimationDisablesDiagramProperty

public static readonly DependencyProperty AnimationDisablesDiagramProperty

value = LayoutManager.AnimationDisablesDiagramProperty

Identifies the AnimationDisablesDiagram dependency property.

AnimationTimeProperty

public static readonly DependencyProperty AnimationTimeProperty

value = LayoutManager.AnimationTimeProperty

Identifies the AnimationTime dependency property.

DefaultLocationProperty

public static readonly DependencyProperty DefaultLocationProperty

value = LayoutManager.DefaultLocationProperty

Identifies the DefaultLocation dependency property.

InitialProperty

public static readonly DependencyProperty InitialProperty

value = LayoutManager.InitialProperty

Identifies the Initial dependency property.
