Class Drawable

Known Direct Subclasses:
Bitmap, Pixmap, Window

public class Drawable
extends GObject

Provides support for drawing points, lines, arcs, and text onto what we call 'drawables'. Drawables, as the name suggests, are things which support drawing onto them and are either org.gnu.gdk.Window or org.gnu.gdk.Pixmap objects.

getClipRegion

public Region getClipRegion()
Computes the Region of a Drawable that potentially can be written to by drawing primitives. This Region will not take into account the clip region for the GC, and may also not take into account other factors such as if the Window is obscured by other Windows.


getColormap

public Colormap getColormap()
Gets the Colormap for the Drawable if one is set; returns null otherwise.


getDepth

public int getDepth()
Obtains the bit depth of the Drawable, this is, the number of bits that make up a pixel.


getDisplay

public Display getDisplay()
Get the Display associated with the Drawable.


getImage

public Image getImage(int x,
                      int y,
                      int width,
                      int height)
Obtains the pixels from a server-side Drawable as a client-side Image. The format of the Image depends on the Visual for the current display which makes manipulating Image extremely difficult.

Parameters:
x -
y -
width -
height -


getScreen

public Screen getScreen()
Get the Screen associated with the Drawable.


getSize

public Dimension getSize()
Returns the size of the Drawable.


getType

public static Type getType()
Retrieve the runtime type used by the GLib library.


getVisibleRegion

public Region getVisibleRegion()
Computes the Region of a Drawable that is potentially visible.


getVisual

public Visual getVisual()
Gets the Visual describing the pixel format of this Drawable.


setColormap

public void setColormap(Colormap cmap)
Sets the Colormap associated with the Drawable. Normally this happens automatically when the Drawable is created.

Parameters:
cmap -
