class	mxGdiCanvas2D
	Used for exporting images. To render to an image from a given XML string, graph size and and background color, the following code is used: More...
class	mxGeometry
	Represents the geometry of a cell. For vertices, the geometry consists of the x- and y-location, as well as the width and height. For edges, the edge either defines the source- and target-terminal, or the geometry defines the respective terminal points. More...
class	mxGraph
	Implements a graph object that allows to create diagrams from a graph model and stylesheet. More...
class	mxGraphModel
	Implements a graph model. The graph model acts as a wrapper around the cells which are in charge of storing the actual graph datastructure. The model acts as a transactional wrapper with event notification for all changes, whereas the cells contain the atomic operations for updating the actual datastructure. More...
class	mxGraphView
	Implements a view for the graph. This class is in charge of computing the absolute coordinates for the relative child geometries, the points for perimeters and edge styles and keeping them cached in mxCellStates for faster retrieval. The states are updated whenever the model or the view state (translate, scale) changes. The scale and translate are honoured in the bounds. More...

	A converter that renders display XML data onto a GDI canvas. More...
class	mxGraphViewReader
	An abstract converter that renders display XML data onto a canvas. More...

interface	mxICell
	Defines the requirements for a cell that can be used in an mxGraphModel. More...
interface	mxIGraphLayout
	Defines the requirements for an object that implements a graph layout. More...
interface	mxIGraphModel
	Defines the requirements for a graph model to be used with mxGraph. More...
class	mxImageBundle
	Maps from keys to base64 encoded images or file locations. All values must be URLs or use the format data:image/format followed by a comma and the base64 encoded image data, eg. "data:image/gif,XYZ", where XYZ is the base64 encoded image data. More...

	Implements a canvas that draws onto an image. More...
class	mxModelCodec
	Codec for mxGraphModels. This class is created and registered dynamically at load time and used implicitely via mxCodec and the mxCodecRegistry. More...
class	mxObjectCodec
	Generic codec for C# objects. See below for a detailed description of the encoding/decoding scheme. Note: Since booleans are numbers in JavaScript, all boolean values are encoded into 1 for true and 0 for false. More...
class	mxPerimeter
	Provides various perimeter functions to be used in a style as the value of mxConstants.STYLE_PERIMETER. More...
class	mxPoint
	Implements a 2-dimensional point with double precision coordinates. More...
class	mxRectangle
	Implements a 2-dimensional rectangle with double precision coordinates. More...
class	mxSaxOutputHandler
class	mxStencil
	Implements a stencil for the given XML definition. This class implements the mxGraph stencil schema. More...
class	mxStencilRegistry
class	mxStyleRegistry
	Static class that acts as a global registry for codecs. See mxCodec for an example of using this class. More...
class	mxStylesheet
	Defines the appearance of the cells in a graph. More...
class	mxStylesheetCodec
	Codec for mxStylesheets. This class is created and registered dynamically at load time and used implicitely via mxCodec and the mxCodecRegistry. More...
class	mxUtils
	Contains various helper methods for use with mxGraph. More...

Functions
delegate void	mxGraphModelChangeEventHandler ()
	Defines the requirements for an object that listens to a graph model. More...
delegate void	mxEdgeStyleFunction (mxCellState state, mxCellState source, mxCellState target, List< mxPoint > points, List< mxPoint > result)
	Defines the requirements for an edge style function. At the time the function is called, the result array contains a placeholder (null) for the first absolute point, that is, the point where the edge and source terminal are connected. The implementation of the style then adds all intermediate waypoints except for the last point, that is, the connection point between the edge and the target terminal. The first ant the last point in the result array are then replaced with mxPoints that take into account the terminal's perimeter and next point on the edge. More...
delegate mxPoint	mxPerimeterFunction (mxRectangle bounds, mxCellState vertex, mxPoint next, bool orthogonal)
	Defines the requirements for a perimeter function. More...

Function Documentation

mxEdgeStyleFunction()

delegate void com.mxgraph.mxEdgeStyleFunction	(	mxCellState	state,
		mxCellState	source,
		mxCellState	target,
		List< mxPoint >	points,
		List< mxPoint >	result
	)

Defines the requirements for an edge style function. At the time the function is called, the result array contains a placeholder (null) for the first absolute point, that is, the point where the edge and source terminal are connected. The implementation of the style then adds all intermediate waypoints except for the last point, that is, the connection point between the edge and the target terminal. The first ant the last point in the result array are then replaced with mxPoints that take into account the terminal's perimeter and next point on the edge.

Parameters

state	Cell state that represents the edge to be updated.
source	Cell state that represents the source terminal.
target	Cell state that represents the target terminal.
points	List of relative control points.
result	Array of points that represent the actual points of the edge.

mxGraphModelChangeEventHandler()

delegate void com.mxgraph.mxGraphModelChangeEventHandler

(

)

Defines the requirements for an object that listens to a graph model.

mxPerimeterFunction()

delegate mxPoint com.mxgraph.mxPerimeterFunction	(	mxRectangle	bounds,
		mxCellState	vertex,
		mxPoint	next,
		bool	orthogonal
	)

Defines the requirements for a perimeter function.

Parameters

bounds	Rectangle that represents the absolute bounds of the vertex.
vertex	Cell state that represents the vertex.
next	Point that represents the nearest neighbour point on the given edge.
orthogonal	Boolean that specifies if the orthogonal projection onto the perimeter should be returned. If this is false then the intersection of the perimeter and the line between the next and the center point is returned.
