                         int height,
                         int dx,
                         int dy)
Overrides:
copyAreaImpl in interface ComponentGraphics

create

public Graphics create()
These are declared abstract as there may be context-specific issues.
Overrides:
create in interface ComponentGraphics

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.
Overrides:
draw in interface ComponentGraphics

drawGlyphVector

public void drawGlyphVector(GlyphVector gv,
                            float x,
                            float y)
Draws a glyph vector at the specified location.
Overrides:
drawGlyphVector in interface ComponentGraphics
Parameters:
x - the x-coordinate.
y - the y-coordinate.

drawImage

public boolean drawImage(Image img,
                         int x,

Parameters:
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.
Returns:
true if all the image data is available, false otherwise.

drawImage

public boolean drawImage(Image img,

y - The Y coordinate of the point to draw at.
observer - The image observer to notify as data becomes available.
Returns:
true if all the image data is available, false otherwise.
