getOrCreateRef

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

changeAutoChildDefaults

public static void changeAutoChildDefaults(java.lang.String autoChildName,
                                           Canvas defaults)

Changes the defaults for Canvas AutoChildren named autoChildName.

Parameters:

autoChildName - name of an AutoChild to customize the defaults for.

defaults - Canvas defaults to apply. These defaults override any existing properties without destroying or wiping out non-overridden properties. For usage tips on this param, see SGWTProperties.

changeAutoChildDefaults

public static void changeAutoChildDefaults(java.lang.String autoChildName,
                                           FormItem defaults)

Changes the defaults for FormItem AutoChildren named autoChildName.

Parameters:

autoChildName - name of an AutoChild to customize the defaults for.

defaults - FormItem defaults to apply. These defaults override any existing properties without destroying or wiping out non-overridden properties. For usage tips on this param, see SGWTProperties.

create

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

Overrides:

create in class DrawPath

setKnobs

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

DrawPolygon only supports the KnobType.MOVE knob type.

Overrides:

setKnobs in class DrawPath

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:

DrawItem.setKnobs(com.smartgwt.client.types.KnobType...)

getKnobs

public KnobType[] getKnobs()

DrawPolygon only supports the KnobType.MOVE knob type.

Overrides:

getKnobs in class DrawPath

Returns:

Current knobs value. Default value is null

See Also:

DrawItem.getKnobs()

setLineCap

Style of drawing the corners of the polygon.

Overrides:

getLineCap in class DrawItem

Returns:

Current lineCap value. Default value is "butt"

setPoints

public void setPoints(Point... points)

Array of points of the polygon, specified in the local coordinate system.

Overrides:

getPoints

public Point[] getPoints()

Array of points of the polygon, specified in the local coordinate system.

Overrides:

setShowTitleLabelBackground

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 DrawPath

Parameters:

showTitleLabelBackground - New showTitleLabelBackground value. Default value is false

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).

Returns:

Current titleRotationMode value. Default value is "withItemAlwaysUp"

See Also:

DrawItem.getTitle()

setDefaultProperties

public static void setDefaultProperties(DrawPolygon drawPolygonProperties)

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:

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