Class JXG.ForeignObject

JXG.GeometryElement,JXG.CoordsElement
      ↳ JXG.ForeignObject

Creates a new foreignObject object. Do not use this constructor to create a foreignObject. Use JXG.Board#create with type foreignobject instead.

Defined in: foreignobject.js.
Extends JXG.CoordsElement, JXG.GeometryElement.

Class Detail
JXG.ForeignObject(board, coordinates, attributes, url, size)
Construct and handle SVG foreignObjects.
Parameters:
{string|JXG.Board} board
The board the new foreignObject is drawn on.


{Array} coordinates
An array with the user coordinates of the foreignObject.


{Object} attributes
An object containing visual and - optionally - a name and an id.


{string|function} url
An URL string or a function returning an URL string.


{Array} size
Array containing width and height of the foreignObject in user coordinates.


Field Detail
content
'href' of the foreignObject.

{Array} size
Array of length two containing [width, height] of the foreignObject in pixel.
Method Detail
{number} H()
Returns the height of the foreignObject in user coordinates.
Returns:
{number} height of the image in user coordinates

{Boolean} hasPoint(x, y)
Checks whether (x,y) is over or near the image;
Parameters:
{Number} x
Coordinate in x direction, screen coordinates.
{Number} y
Coordinate in y direction, screen coordinates.
Returns:
{Boolean} True if (x,y) is over the image, False otherwise.

{JXG.ForeignObject} setSize(width, height)
Set the width and height of the foreignObject. After setting a new size, board.update() or foreignobject.fullUpdate() has to be called to make the change visible.
Parameters:
{number|function|string} width
Number, function or string that determines the new width of the foreignObject
{number|function|string} height
Number, function or string that determines the new height of the foreignObject
Returns:
{JXG.ForeignObject} A reference to the element

<private> {JXG.ForeignObject} update(fromParent)
Recalculate the coordinates of lower left corner and the width and height.
Parameters:
fromParent
Returns:
{JXG.ForeignObject} A reference to the element

<private> updateRenderer()
Send an update request to the renderer.

<private> {JXG.ForeignObject} updateSize()
Updates the internal arrays containing size of the foreignObject.
Returns:
{JXG.ForeignObject} A reference to the element

<private> {JXG.ForeignObject} updateSpan()
Update the anchor point of the foreignObject, i.e. the lower left corner and the two vectors which span the rectangle.
Returns:
{JXG.ForeignObject} A reference to the element

{number} W()
Returns the width of the foreignObject in user coordinates.
Returns:
{number} width of the image in user coordinates
