 sun.porting.graphicssystem.CursorImage
| CursorImage | | abstract public class CursorImage (Code) | | CursorImage is an object which encapsulates the bitmap and hotspot
data describing a cursor. It is used simply to hold all of the
required information in one place. It also enables the native
implementation to build a cursor from this image data and cache it.
version:
1.8, 08/19/02 |
| Field Summary | |
| protected int | hotX
The x coordinate of the cursor hot spot, i.e. | | protected int | hotY
The y coordinate of the cursor hot spot, i.e. | | protected java.awt.Image | image
An image which contains the shape of the cursor. |
| Constructor Summary | |
| public | CursorImage(java.awt.Image imageData, int x, int y)
Create a new CursorImage object from the given image data and hotspot. |
| hotX | | protected int hotX(Code) | | The x coordinate of the cursor hot spot, i.e. the coordinate within
the image that corresponds to the cursor's location on screen.
|
| hotY | | protected int hotY(Code) | | The y coordinate of the cursor hot spot, i.e. the coordinate within
the image that corresponds to the cursor's location on screen.
|
| image | | protected java.awt.Image image(Code) | | An image which contains the shape of the cursor. Image transparency
is used to determine which pixels of the cursor are painted and which
are not. Colors in the image should be retained whenever possible (e.g.
if the underlying graphics system supports colored cursors). At a
minimum, three pixel values (black, white, transparent) should be
significant.
|
| CursorImage | | public CursorImage(java.awt.Image imageData, int x, int y)(Code) | | Create a new CursorImage object from the given image data and hotspot.
It is the responsibility of the caller to make sure that the image data
contains no more colors than are supported by the graphics system, and
that the size of the cursor image is supported.
Parameters:
imageData - An image, probably with transparency, which describesthe shape and coloration of the cursor.
Parameters:
x - The x coordinate of the cursor hotspot.
Parameters:
y - The y coordinate of the cursor hotspot.
