}

Returns the status of the construction of a scaled screen representation of the specified image.

This method does not cause the image to begin loading. An application must use the prepareImage (II-§3.6.17) method to force the loading of an image.

Information on the flags returned by this method can be found in (II-§2.11).

Parameters:

img - the Image whose status is being checked

w - the width of the scaled version to check the status of

h - the height of the scaled version to check the status of

o - the ImageObserver object to be notified as the image is being prepared

Returns:

the bitwise inclusive OR of the ImageObserver (II-§2.11) flags for the data that is currently available

See Also:

prepareImage (II-§3.6.17).

Creates an image from the specified image producer.

Parameters:

producer - the image producer

Returns:

the image produced

Creates an off-screen drawable image to be used for double buffering.

Parameters:

width - the specified width

height - the specified height

Returns:

an off-screen drawable image.

Makes the component insensitive to user input.

See Also:

enable (II-§3.6.6).

Disposes of the component peer and any resources used by it

Makes the component sensitive to user input. This is the default.

See Also:

disable (II-§3.6.4).

Gets the component's color model (II-§2.1), which is an abstract class that encapsulates how to translate between pixel values of an image and its red, green, blue, and alpha components.

Returns:

the color model of the component.

Parameters:

font - the font

Returns:

the font metrics for this component; if the component is not currently on the screen, this method returns null.

Returns:

the graphics context of this component; this method returns null if the component is not currently on the screen.

See Also:

paint (II-§3.6.15).

Returns:

the toolkit that component peer is part of.

This method is called when any event occurs inside the component.

The method must return true to indicate that it has successfully handled the action; or false if the event that triggered the action should be passed up to the component's containing object.

Parameters:

e - the event

Returns:

false if the event is to be given to the component's containing object; true if the event has been handled and no further action is necessary.

Hides the component.

See Also:

show (II-§3.6.26).

Returns:

the minimum size of this component.

See Also:

preferredSize (II-§3.6.16).

Moves the focus to the next component.

Paints the component.

The coordinate of the graphics context is the top-left corner of the components. The clipping region of the graphics context is the rectangle of the component.

Parameters:

g - the graphics context to use for painting.

Returns:

the preferred size of this component.

See Also:

minimumSize (II-§3.6.13).

Prepares an image for rendering on this component at the specified width and height.

The image data is downloaded asynchronously in another thread and an appropriately scaled screen representation of the image is generated.

Parameters:

image - the Image to prepare a screen representation for

width - the width of the desired screen representation

height - the height of the desired screen representation

observer - the ImageObserver object to be notified as the image is being prepared

Returns:

true if the image has already been fully prepared; false otherwise.

See Also:

ImageObserver (II-§2.11).

Prints this component.

The coordinate of the graphics context is the top-left corner of the components. The clipping region of the graphics context is the rectangle of the component

See Also:

paint (II-§3.6.15).

Repaints the specified rectangle of the component.

Parameters:

x - the x coordinate

y - the y coordinate

width - the width

height -

See Also:

paint (II-§3.6.15).

Requests the input focus.

Reshapes the component to the specified bounding rectangle.

Parameters:

x - the x coordinate

y - the y coordinate

width - the width of the component

height - the height of the component

Sets the background color for the component.

Parameters:

c - the color

Sets the font of the component.

Parameters:

f - the font

Sets the foreground color for the component.

Parameters:

c - the color

Shows the component: if the component had been made invisible by a call to the hide method (II-§3.6.12), make the component visible again.
