		double	width,
		double	height,
		string	style,
		bool	relative
	)			`[inline]`

Adds a new vertex into the given parent using value as the user object and the given coordinates as the geometry of the new vertex. The id and style are used for the respective properties of the new cell, which is returned.

Parameters:

	parent	Cell that specifies the parent of the new vertex.
	id	Optional string that defines the Id of the new vertex.
	value	Object to be used as the user object.

	y	Integer that defines the y coordinate of the vertex.
	width	Integer that defines the width of the vertex.
	height	Integer that defines the height of the vertex.
	style	Optional string that defines the cell style.

Returns:: Returns the new vertex that has been inserted.

bool com::mxgraph::mxGraph::Intersects	(	mxCellState	state,
		Rectangle	rect
	)			`[inline]`

Returns the bottom-most cell that intersects the given point (x, y) in the cell hierarchy that starts at the given parent.

Parameters:

Returns:: Returns true if the given cell state and rectangle intersect.

bool com::mxgraph::mxGraph::IsCellCollapsed ( Object cell ) [inline]

Returns true if the given cell is collapsed. This implementation returns true if the collapsed state of the cell in the model is true.

Parameters:

cell

Cell whose collapsed state should be returned.

Returns:: Returns the collapsed state of the cell.

bool com::mxgraph::mxGraph::IsCellConnectable ( Object cell ) [inline]
