Method Detail

getOrCreateRef

public static DrawPath getOrCreateRef(JavaScriptObject jsObj)

create

public JavaScriptObject create()

Overrides:

create in class DrawItem

setKnobs

public void setKnobs(KnobType... knobs)
              throws java.lang.IllegalStateException

DrawPath only supports the KnobType.MOVE knob type.

Overrides:

setKnobs in class DrawItem

Parameters:

knobs - Default value is null

Throws:

java.lang.IllegalStateException - this property cannot be changed after the underlying component has been created

See Also:

DrawItem.setKnobs(com.smartgwt.client.types.KnobType...), Diagramming Example

getKnobs

public KnobType[] getKnobs()

DrawPath only supports the KnobType.MOVE knob type.

Overrides:

getKnobs in class DrawItem

Returns:

KnobType...

See Also:

DrawItem.getKnobs(), Diagramming Example

setPoints

public void setPoints(Point... points)

Array of Points for the line.

Parameters:

points - Default value is [[0,0], [100,100]]

getPoints

public Point[] getPoints()

Array of Points for the line.

Returns:

Point...

getCenter

public Point getCenter()

Get the mean center of the path.

Overrides:

getCenter in class DrawItem

Returns:

the mean center

moveBy

public void moveBy(int dX,
          int dY)

Move the points by dX,dY

Overrides:

moveBy in class DrawItem

Parameters:

dX - delta x coordinate in pixels

dY - delta y coordinate in pixels

moveFirstPointTo

public void moveFirstPointTo(java.lang.Integer left,
                    java.lang.Integer top)

Move all points in the path such that the first point ends up at the specified coordinates and the line lengths and angles are unchanged.

Parameters:

left - new left coordinate in pixels

top - new top coordinate in pixels

resizeBy

public void resizeBy(int dX,
            int dY)

Resize by the specified delta

Overrides:

resizeBy in class DrawItem

Parameters:

dX - number of pixels to resize by horizontally

dY - number of pixels to resize by vertically

resizeTo

public void resizeTo(java.lang.Integer width,
            java.lang.Integer height)

Resize to the specified size

Overrides:

resizeTo in class DrawItem

Parameters:

width - new width

height - new height

setDefaultProperties

public static void setDefaultProperties(DrawPath drawPathProperties)

Class level method to set the default properties of this class. If set, then all existing and subsequently created instances of this class will automatically have default properties corresponding to the properties set on the SmartGWT class instance passed to this function before its underlying SmartClient JS object was created. This is a powerful feature that eliminates the need for users to create a separate hierarchy of subclasses that only alter the default properties of this class. Can also be used for skinning / styling purposes.

Note: This method is intended for setting default attributes only and will affect all instances of the underlying class (including those automatically generated in JavaScript). This method should not be used to apply standard EventHandlers or override methods for a class - use a custom subclass instead. Calling this method after instances have been created can result in undefined behavior, since it bypasses any setters and a class instance may have already examined a particular property and not be expecting any changes through this route.

Parameters:

drawPathProperties - properties that should be used as new defaults when instances of this class are created
