Class ComponentGraphics
ComponentGraphics - context for drawing directly to a component,
as this is an X drawable, it requires that we use GTK locks.
This context draws directly to the drawable and requires xrender.
void | copyAreaImpl(int x, int y, int width, int height, int dx, int dy)
|
Graphics | create() - These are declared abstract as there may be context-specific issues.
|
void | dispose() - Destroys the component surface and calls dispose on the cairo
graphics2d to destroy any super class resources.
|
void | draw(Shape s) - Overloaded methods that do actual drawing need to enter the gdk threads
and also do certain things before and after.
|
void | drawGlyphVector(GlyphVector gv, float x, float y) - Draws a glyph vector at the specified location.
|
boolean | drawImage(Image img, int x, int y, int width, int height, ImageObserver observer) - Draws all of the image that is available and returns.
|
boolean | drawImage(Image img, int x, int y, ImageObserver observer) - Draws all of the image that is available and returns.
|
protected boolean | drawImage(Image img, AffineTransform xform, Color bgcolor, ImageObserver obs)
|
void | drawLine(int x1, int y1, int x2, int y2) - Draws a line between the two specified points.
|
void | drawRect(int x, int y, int width, int height) - Draws the outline of the specified rectangle.
|
void | drawRenderedImage(RenderedImage image, AffineTransform xform)
|
void | fill(Shape s) - Fills the interior of the specified
shape using the current
paint.
|
void | fillRect(int x, int y, int width, int height) - Fills the area bounded by the specified rectangle.
|
static Graphics2D | getComponentGraphics(GtkComponentPeer component) - Returns a Graphics2D object for a component, either an instance of this
class (if xrender is supported), or a context which copies.
|
GraphicsConfiguration | getDeviceConfiguration()
|
protected Rectangle2D | getRealBounds()
|
static GtkImage | grab(GtkComponentPeer component) - Not really related (moveme?).
|
static boolean | hasXRender() - Query if the system has the XRender extension.
|
protected long | initFromVolatile(long pixmapPtr, int width, int height) - Creates a cairo_t for a volatile image
|
void | setClip(Shape s) - Sets the clipping region to the specified
Shape .

dispose
public void dispose()
Destroys the component surface and calls dispose on the cairo
graphics2d to destroy any super class resources.
- dispose in interface CairoGraphics2D
draw
public void draw(Shape s)
Overloaded methods that do actual drawing need to enter the gdk threads
and also do certain things before and after.
- draw in interface CairoGraphics2D
drawImage
public boolean drawImage(Image img,
int x,
int y,
int width,
int height,
ImageObserver observer)
Draws all of the image that is available and returns. The image
is scaled to fit in the specified rectangle. If the image
is not completely loaded, false
is returned and
the specified iamge observer is notified as more data becomes
available.
- drawImage in interface CairoGraphics2D
x
- The X coordinate of the point to draw at.y
- The Y coordinate of the point to draw at.width
- The width of the rectangle to draw in.height
- The height of the rectangle to draw in.observer
- The image observer to notify as data becomes available.
true
if all the image data is available,
false
otherwise.
drawImage
public boolean drawImage(Image img,
int x,
int y,
ImageObserver observer)
Draws all of the image that is available and returns. If the image
is not completely loaded, false

x
- The X coordinate of the point to draw at.y
- The Y coordinate of the point to draw at.observer
- The image observer to notify as data becomes available.
