DrawPath only supports the KnobType.MOVE knob type.

Overrides:

setKnobs in class DrawItem

Parameters:

knobs - New knobs value. Default value is null

Throws:

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

See Also:

getKnobs

public KnobType[] getKnobs()

DrawPath only supports the KnobType.MOVE knob type.

Overrides:

getKnobs in class DrawItem

Returns:

Current knobs value. Default value is null

See Also:

DrawItem.getKnobs()

setPoints

public void setPoints(Point... points)

Array of Points for the line, specified in the local coordinate system.

Parameters:

public void setShowTitleLabelBackground(boolean showTitleLabelBackground)
                                 throws java.lang.IllegalStateException

If the titleLabel is showing, should the titleLabelBackground be created and placed behind the titleLabel?

This defaults to true for DrawSectors and shapes that are not commonly filled (e.g. DrawLines).

Note : This is an advanced setting

Overrides:

setShowTitleLabelBackground in class DrawItem

Parameters:

showTitleLabelBackground - New showTitleLabelBackground value. Default value is true

Throws:

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

getShowTitleLabelBackground

public boolean getShowTitleLabelBackground()

If the titleLabel is showing, should the titleLabelBackground be created and placed behind the titleLabel?

This defaults to true for DrawSectors and shapes that are not commonly filled (e.g. DrawLines).

moveBy

public void moveBy(int dX,
                   int dY)

Move the points by dX,dY

Overrides:

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
