public class Diagram extends DiagramBase implements IItemFactory
It acts as a container for diagram elements such as nodes and links. Nodes are
instances of DiagramNode
-derived classes. The nodes
can be accessed through getNodes()
.
Links in JDiagram are instances of the DiagramLink
class and can be accessed
through the getLinks()
method. Diagram items can be grouped in
hierarchical structures and the so formed groups can be accessed via
getGroups()
.
Managing items: Use the Factory.createShapeNode(float, float, float, float)
, Factory.createTableNode(float, float, float, float)
and
Factory.createDiagramLink(com.mindfusion.diagramming.DiagramNode, com.mindfusion.diagramming.DiagramNode)
methods to create new diagram items. Optionally, items
can be created using the new
operator and added to the diagram
with the add(com.mindfusion.diagramming.DiagramItem)
method. Items are deleted using the deleteItem(com.mindfusion.diagramming.DiagramItem)
method.
The Factory.createGroup(com.mindfusion.diagramming.DiagramItem)
method creates a new hierarchical Group
of
items. The subordinated items in a group always follow the movement of their
master item. Use the destroyGroup(com.mindfusion.diagramming.Group)
method to destroy a group.
Searching for a particular kind of items is done with the
findLink(java.lang.Object)
, findNode(java.lang.Object)
and findGroup(java.lang.Object)
methods, which
look for an item that has a particular Tag
. To get
whatever object is placed at a certain location, use the getItemAt(android.graphics.PointF, boolean)
,
getNodeAt(android.graphics.PointF)
and getLinkAt(android.graphics.PointF, float)
methods.
Serialization: Binary serialization of diagrams is provided by the
saveTo(java.lang.String, android.content.Context)
and loadFrom(java.lang.String, android.content.Context)
methods which serialize diagrams
to / from Java streams or files. Use the saveToXml(java.lang.String)
and loadFromXml(java.lang.String)
methods to serialize a diagram into/from XML documents.
Controlling users actions: Users actions can be validated by handling
some events declared in DiagramListener
, fired while items are
being created or modified. In addition, the Diagram
class
provides some properties that control user interaction. The DiagramView.setBehavior(com.mindfusion.diagramming.Behavior)
method specifies how user interaction with input devices should be interpreted: by creating
nodes, links, selection, etc. The order in which items are hit-tested when clicking
on them depends on the value assigned via setHitTestPriority(com.mindfusion.diagramming.HitTestPriority)
.
The following attribute setters let you control what kind of links users can
create: setAllowLinksRepeat(boolean)
, setAllowSelfLoops(boolean)
,
setAllowUnanchoredLinks(boolean)
, setAllowUnconnectedLinks(boolean)
. To
specify whether users are allowed to edit the text of nodes by double-clicking,
use DiagramView.setAllowInplaceEdit(boolean)
.
