BufferStrategy
2008-05-06 03:33:00
java.awt.imageClass BufferStrategy java.lang.Object java.awt.image.BufferStrategypublic abstract class BufferStrategyextends Object The BufferStrategy class represents the mechanism with which to organize complex memory on a particular Canvas or Window. Hardware and software limitations determine whether and how a particular buffer strategy can be implemented. These limitations are detectible through the capabilities of the GraphicsConfiguration used when creating the Canvas or Window. It is worth noting that the terms buffer and surface are meant to be synonymous: an area of contiguous memory, either in video device memory or in system memory. There are several types of complex buffer strategies; sequential ring buffering, blit buffering, and stereo buffering are common types. Sequential ring buffering (i.e., double or triple buffering) is the most common; an application draws to a single back buffer and then moves the contents to the front (display) in a si...

BorderLayout
2008-05-06 03:30:00
java.awtClass BorderLayout java.lang.Object java.awt.BorderLayoutpublic class BorderLayoutextends Objectimplements LayoutManager2, Serializable A border layout lays out a container, arranging and resizing its components to fit in five regions: north, south, east, west, and center. Each region may contain no more than one component, and is identified by a corresponding constant: NORTH, SOUTH, EAST, WEST, and CENTER. When adding a component to a container with a border layout, use one of these five constants, for example: Panel p = new Panel(); p.setLayout(new BorderLayout()); p.add(new Button("Okay"), BorderLayout.SOUTH); As a convenience, BorderLayout interprets the absence of a string specification the same as the constant CENTER: Panel p2 = new Panel(); p2.setLayout(new BorderLayout()); p2.add(new TextArea()); // Same as p.add(new TextArea(), BorderLayout.CENTER); In addition, BorderLayout supports the relative positioning constan...

BasicStroke
2008-05-06 03:29:00
java.awtClass BasicStroke java.lang.Object java.awt.BasicStroke The BasicStroke class defines a basic set of rendering attributes for the outlines of graphics primitives, which are rendered with a Graphics2D object that has its Stroke attribute set to this BasicStroke. The rendering attributes defined by BasicStroke describe the shape of the mark made by a pen drawn along the outline of a Shape and the decorations applied at the ends and joins of path segments of the Shape. These rendering attributes include: width The pen width, measured perpendicularly to the pen trajectory. end caps The decoration applied to the ends of unclosed subpaths and dash segments. Subpaths that start and end on the same point are still considered unclosed if they do not have a CLOSE segment. See SEG_CLOSE for more information on the CLOSE segment. The three different decorations are: CAP_BUTT, CAP_ROUND, and CAP_SQUARE. line joins The decoration applied at the intersection of two...

AWTKeyStroke
2008-05-06 03:28:00
java.awtClass AWTKeyStroke java.lang.Object java.awt.AWTKeyStrokepublic class AWTKeyStrokeextends Objectimplements Serializable An AWTKeyStroke represents a key action on the keyboard, or equivalent input device. AWTKeyStrokes can correspond to only a press or release of a particular key, just as KEY_PRESSED and KEY_RELEASED KeyEvents do; alternately, they can correspond to typing a specific Java character, just as KEY_TYPED KeyEvents do. In all cases, AWTKeyStrokes can specify modifiers (alt, shift, control, meta, or a combination thereof) which must be present during the action for an exact match. AWTKeyStrokes are immutable, and are intended to be unique. Client code should never create an AWTKeyStroke on its own, but should instead use a variant of getAWTKeyStroke. Client use of these factory methods allows the AWTKeyStroke implementation to cache and share instances efficiently.

Interface InputMethodListener
2008-05-06 03:27:00
java.awt.eventInterface InputMethodListenerhe listener interface for receiving input method events. A text editing component has to install an input method event listener in order to work with input methods. The text editing component also has to provide an instance of InputMethodRequests.

Interface ContainerListener
2008-05-06 03:26:00
java.awt.eventInterface ContainerListenerThe listener interface for receiving container events. The class that is interested in processing a container event either implements this interface (and all the methods it contains) or extends the abstract ContainerAdapter class (overriding only the methods of interest). The listener object created from that class is then registered with a component using the component's addContainerListener method. When the container's contents change because a component has been added or removed, the relevant method in the listener object is invoked, and the ContainerEvent is passed to it.

AWTEventMulticaster

java.awtClass AWTEventMulticaster java.lang.Object java.awt.AWTEventMulticasterpublic class AWTEventMulticasterextends Objectimplements ComponentListener, ContainerListener, FocusListener, KeyListener, MouseListener, MouseMotionListener, WindowListener, WindowFocusListener, WindowStateListener, ActionListener, ItemListener, AdjustmentListener, TextListener, InputMethodListener, HierarchyListener, HierarchyBoundsListener, MouseWheelListener A class which implements efficient and thread-safe multi-cast event dispatching for the AWT events defined in the java.awt.event package. This class will manage an immutable structure consisting of a chain of event listeners and will dispatch events to those listeners. Because the structure is immutable, it is safe to use this API to add/remove listeners during the process of an event dispatch operation. However, event listeners added during the process of an event dispatch operation will not be notified of the event currently bein...

AlphaComposite
2008-05-06 03:23:00
java.awtClass AlphaComposite java.lang.Object java.awt.AlphaCompositepublic final class AlphaCompositeextends Objectimplements Composite The AlphaComposite class implements basic alpha compositing rules for combining source and destination colors to achieve blending and transparency effects with graphics and images. The specific rules implemented by this class are the basic set of 12 rules described in T. Porter and T. Duff, "Compositing Digital Images", SIGGRAPH 84, 253-259. The rest of this documentation assumes some familiarity with the definitions and concepts outlined in that paper. This class extends the standard equations defined by Porter and Duff to include one additional factor. An instance of the AlphaComposite class can contain an alpha value that is used to modify the opacity or coverage of every source pixel before it is used in the blending equations. It is important to note that the equations defined by the Porter and Duff paper are all defi...
