This class implements the functionality of a UIGraphic object in an AWT-based control. An AwtUIGraphic control is an AwtUIHost component whose associated root container holds a UIGraphic object. By hosting this object, an AwtUIGraphic control integrates AFC with AWT. although an AwtUIGraphic control is fully compatible with AWT, a UIGraphic control is optimized for performance and size.

Constructors

AwtUIGraphic

public AwtUIGraphic();

Creates an AWT-based graphic control with no image.

AwtUIGraphic

public AwtUIGraphic(Image image);

Creates an AWT-based graphic control with the specified image.

Parameter	Description
image	The image to be displayed within the control.

Remarks:

By default, the image is aligned both horizontally and vertically.

AwtUIGraphic

public AwtUIGraphic(Image image, int justify);

Creates an AWT-based graphic control with the specified image and style.

Parameter	Description
image	The image to be displayed within the control.
justify	The alignment and style of the control. You can pass any bitwise combination of an alignment flag and a style flag. For a list of possible flags, see the UIStatic.setFlags method.

Remarks:

If a vertical alignment is not specified, VCENTER is used by default. Similarly, if a horizontal alignment is not specified, HCENTER is used.

Exceptions:

IllegalArgumentException if more than one vertical alignment, more than one horizontal alignment, or an undefined style was specified.

Methods

getBase

public IUIComponent getBase();

Retrieves the UI component that the control is based on.

Return Value:

Returns the UIGraphic object associated with the control.

Remarks:

When the AWT-based control is first created, it is associated with a UIGraphic object.

getContentBounds

public Rectangle getContentBounds();

Retrieves the bounding rectangle of the control's contents.

Return Value:

Returns a Rectangle object that defines the content area within the control's coordinate space.

getImage

public Image getImage();

Retrieves the control's image.

Return Value:

Returns the Image object displayed within the control.

imageUpdate

public boolean imageUpdate(Image image, int flags, int x, int y, int width,
        int height);

Incrementally draws the control's image as the bits become available.

Return Value:

Returns true if more information is needed to draw the full image; otherwise, returns false.

Parameter	Description
image	The control's image.
flags	The flags that specify the status of the image that is being loaded. You can pass any bitwise combination of the fields that are defined in the ImageObserver interface.
x	The x coordinate of the image.
y	The y coordinate of the image.
width	The width of the image (in pixels).
height	The height of the image (in pixels).
