| Method Summary |
|
| native public void | beep()
Emits an audio beep. |
| public int | checkImage(Image img, int w, int h, ImageObserver o)
Indicates the construction status of a specified image that is
being prepared for display.
If the values of the width and height arguments are both
-1, this method returns the construction status of
a screen representation of the specified image in this toolkit.
Otherwise, this method returns the construction status of a
scaled representation of the image at the specified width
and height.
This method does not cause the image to begin loading.
An application must call prepareImage to force
the loading of an image.
This method is called by the component's checkImage
methods.
Information on the flags returned by this method can be found
with the definition of the ImageObserver interface.
Parameters:
image - the image whose status is being checked.
Parameters:
width - the width of the scaled version whose status isbeing checked, or -1.
Parameters:
height - the height of the scaled version whose statusis being checked, or -1.
Parameters:
observer - the ImageObserver object to benotified as the image is being prepared. |

| public boolean | prepareImage(Image img, int w, int h, ImageObserver o)
|
| static boolean | prepareScrImage(Image img, int w, int h, ImageObserver o)
Prepares an image for rendering.
If the values of the width and height arguments are both
-1, this method prepares the image for rendering
on the default screen; otherwise, this method prepares an image
for rendering on the default screen 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.
This method is called by components prepareImage
methods.
Information on the flags returned by this method can be found
with the definition of the ImageObserver interface.
Parameters:
image - the image for which to prepare ascreen representation.
Parameters:
width - the width of the desired screenrepresentation, or -1.
Parameters:
height - the height of the desired screenrepresentation, or -1.
Parameters:
observer - the ImageObserverobject to be notified as theimage is being prepared. |
