DrawPath

public DrawPath()

DrawPath

public DrawPath(com.google.gwt.core.client.JavaScriptObject jsObj)

Method Detail

getOrCreateRef

public static DrawPath getOrCreateRef(com.google.gwt.core.client.JavaScriptObject jsObj)

create

public com.google.gwt.core.client.JavaScriptObject create()

Overrides:

create in class DrawItem

setKnobs

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

NOTE: DrawPath items do not support knobs.

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

getKnobs

public KnobType[] getKnobs()

NOTE: DrawPath items do not support knobs.

Overrides:

getKnobs in class DrawItem

Returns:

KnobType...

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.

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

moveTo

public void moveTo(int left,
          int top)

Move both the start and end points of the line, such that the startPoint ends up at the specified coordinate and the line length and angle are unchanged.

Parameters:

left - new startLeft coordinate in pixels

top - new startTop coordinate in pixels

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
