- * IMPORTANT: This class is not intended to be subclassed. - *

- * - *

- * A drag source is the object which originates a drag and drop operation. For - * the specified widget, it defines the type of data that is available for - * dragging and the set of operations that can be performed on that data. The - * operations can be any bit-wise combination of DND.MOVE, DND.COPY or DND.LINK. - * The type of data that can be transferred is specified by subclasses of - * Transfer such as TextTransfer or FileTransfer. The type of data transferred - * can be a predefined system type or it can be a type defined by the - * application. For instructions on how to define your own transfer type, refer - * to ByteArrayTransfer. - *

- * - *

- * You may have several DragSources in an application but you can only have one - * DragSource per Control. Data dragged from this DragSource can be dropped on a - * site within this application or it can be dropped on another application such - * as an external Text editor. - *

- * - *

- * The application supplies the content of the data being transferred by - * implementing the DragSourceListener and associating it with the - * DragSource via DragSource#addDragListener. - *

- * - *

- * When a successful move operation occurs, the application is required to take - * the appropriate action to remove the data from its display and remove any - * associated operating system resources or internal references. Typically in a - * move operation, the drop target makes a copy of the data and the drag source - * deletes the original. However, sometimes copying the data can take a long - * time (such as copying a large file). Therefore, on some platforms, the drop - * target may actually move the data in the operating system rather than make a - * copy. This is usually only done in file transfers. In this case, the drag - * source is informed in the DragEnd event that a DROP_TARGET_MOVE was - * performed. It is the responsibility of the drag source at this point to clean - * up its displayed information. No action needs to be taken on the operating - * system resources. - *

- * - *

- * The following example shows a Label widget that allows text to be dragged - * from it. - *

- * - * 
- * 	// Enable a label as a Drag Source
- * 	Label label = new Label(shell, SWT.NONE);
- * 	// This example will allow text to be dragged
- * 	Transfer[] types = new Transfer[] {TextTransfer.getInstance()};
- * 	// This example will allow the text to be copied or moved to the drop target
- * 	int operations = DND.DROP_MOVE | DND.DROP_COPY;
- * 
- * 	DragSource source = new DragSource(label, operations);
- * 	source.setTransfer(types);
- * 	source.addDragListener(new DragSourceListener() {
- * 		public void dragStart(DragSourceEvent e) {
- * 			// Only start the drag if there is actually text in the
- * 			// label - this text will be what is dropped on the target.
- * 			if (label.getText().length() == 0) {
- * 				event.doit = false;
- * 			}
- * 		};
- * 		public void dragSetData(DragSourceEvent event) {
- * 			// A drop has been performed, so provide the data of the
- * 			// requested type.
- * 			// (Checking the type of the requested data is only
- * 			// necessary if the drag source supports more than
- * 			// one data type but is shown here as an example).
- * 			if (TextTransfer.getInstance().isSupportedType(event.dataType)){
- * 				event.data = label.getText();
- * 			}
- * 		}
- * 		public void dragFinished(DragSourceEvent event) {
- * 			// A Move operation has been performed so remove the data
- * 			// from the source
- * 			if (event.detail == DND.DROP_MOVE)
- * 				label.setText("");

It also - * specifies what data types can be dropped on this control and what operations - * can be performed. You may have several DropTragets in an application but - * there can only be a one to one mapping between a Control and a - * DropTarget.

- *
- * - *

- * The application is notified of data being dragged over this control and of - * when a drop occurs by implementing the interface - * DropTargetListener which uses the class - * DropTargetEvent. The application can modify the type of drag - * being performed on this Control at any stage of the drag by modifying the - * event.detail field or the event.currentDataType - * field. When the data is dropped, it is the responsibility of the application - * to copy this data for its own purposes. - * - *

    - * If loaded from a file format that supports it, an Image may have - * transparency, meaning that certain pixels are specified as being transparent - * when drawn. Examples of file formats that support transparency are GIF and - * PNG. - *

    - *

    - * There are two primary ways to use Images. The first is to load a - * graphic file from disk and create an Image from it. This is done - * using an Image constructor, for example: - * - * 

    - * Image i = new Image(device, "C:\\graphic.bmp");
- *
    - * - * A graphic file may contain a color table specifying which colors the image - * was intended to possess.

It is possible to get more control over - * the mapping of colors as the image is being created, using code of the form: - * - * 
    - * ImageData data = new ImageData("C:\\graphic.bmp");
- * RGB[] rgbs = data.getRGBs();
- * // At this point, rgbs contains specifications of all
- * // the colors contained within this image. You may
- * // allocate as many of these colors as you wish by
- * // using the Color constructor Color(RGB), then
- * // create the image:
- * Image i = new Image(device, data);
- *
    - *

    - * Applications which require even greater control over the image loading - * process should use the support provided in class ImageLoader. - *

    - *

Class - * Shell shares a significant amount of code with this class, and - * is a subclass. - *

    - * IMPORTANT: This class was intended to be abstract and should never - * be referenced or instantiated. Instead, the class Shell should - * be used. - *

    - *

    - * Instances are always displayed in one of the maximized, minimized or normal - * states: - *

      - *
    • - * When an instance is marked as maximized, the window manager will - * typically resize it to fill the entire visible area of the display, and the - * instance is usually put in a state where it can not be resized (even if it - * has style RESIZE) until it is no longer maximized.
      • - *
    • - * When an instance is in the normal state (neither maximized or - * minimized), its appearance is controlled by the style constants which were - * specified when it was created and the restrictions of the window manager (see - * below).
      • - *
    • - * When an instance has been marked as minimized, its contents (client - * area) will usually not be visible, and depending on the window manager, it - * may be "iconified" (that is, replaced on the desktop by a small simplified - * representation of itself), relocated to a distinguished area of the screen, - * or hidden. Combinations of these changes are also possible.
      • - *
    - *

    - * Note: The styles supported by this class must be treated as HINTs, - * since the window manager for the desktop on which the instance is visible has - * ultimate control over the appearance and behavior of decorations. For - * example, some window managers only support resizable windows and will always - * assume the RESIZE style, even if it is not set. - *
    - *
    Styles:
    - *
    BORDER, CLOSE, MIN, MAX, NO_TRIM, RESIZE, TITLE, ON_TOP, TOOL
    - *
    Events:
    - *
    (none)
    - *
    - * Class SWT provides two "convenience constants" for the most - * commonly required style combinations: - *
    - *
    SHELL_TRIM
    - *
    - * the result of combining the constants which are required to produce a typical - * application top level shell: (that is, - * CLOSE | TITLE | MIN | MAX | RESIZE)
    - *
    DIALOG_TRIM
    - *
    - * the result of combining the constants which are required to produce a typical - * application dialog shell: (that is, TITLE | CLOSE | BORDER)

Their most important function is to - * implement the SWT event loop in terms of the platform event model. They also - * provide various methods for accessing information about the operating system, - * and have overall control over the operating system resources which SWT - * allocates. - *

    - * Applications which are built with SWT will almost always require - * only a single display. In particular, some platforms which SWT supports will - * not allow more than one active display. In other words, some - * platforms do not support creating a new display if one already exists that - * has not been sent the dispose() message. - *

    - * In SWT, the thread which creates a Display instance is - * distinguished as the user-interface thread for that display. - *

    - * The user-interface thread for a particular display has the following special - * attributes: - *
      - *
    • - * The event loop for that display must be run from the thread.
      • - *
    • - * Some SWT API methods (notably, most of the public methods in - * Widget and its subclasses), may only be called from the thread. - * (To support multi-threaded user-interface applications, class - * Display provides inter-thread communication methods which allow - * threads other than the user-interface thread to request that it perform - * operations on their behalf.)
      • - *
    • - * The thread is not allowed to construct other Displays until that - * display has been disposed. (Note that, this is in addition to the restriction - * mentioned above concerning platform support for multiple displays. Thus, the - * only way to have multiple simultaneously active displays, even on platforms - * which support it, is to have multiple threads.)
      • - *
    - * Enforcing these attributes allows SWT to be implemented directly on the - * underlying operating system's event model. This has numerous benefits - * including smaller footprint, better use of resources, safer memory - * management, clearer program logic, better performance, and fewer overall - * operating system threads required. The down side however, is that care must - * be taken (only) when constructing multi-threaded applications to use the - * inter-thread communication mechanisms which this class provides when - * required.

    - *

    - * All SWT API methods which may only be called from the user-interface thread - * are distinguished in their documentation by indicating that they throw the " - * ERROR_THREAD_INVALID_ACCESS" SWT exception. - *

- * At any given moment, a given scroll bar will have a single 'selection' that - * is considered to be its value, which is constrained to be within the range of - * values the scroll bar represents (that is, between its minimum and - * maximum values). - *

- *

- * Typically, scroll bars will be made up of five areas: - *

    - *
  1. an arrow button for decrementing the value
    2. - *
  2. a page decrement area for decrementing the value by a larger amount
    3. - *
  3. a thumb for modifying the value by mouse dragging
    4. - *
  4. a page increment area for incrementing the value by a larger amount
    5. - *
  5. an arrow button for incrementing the value
    6. - *
- * Based on their style, scroll bars are either HORIZONTAL (which - * have a left facing button for decrementing the value and a right facing - * button for incrementing it) or VERTICAL (which have an upward - * facing button for decrementing the value and a downward facing buttons for - * incrementing it). - *

- *

- * On some platforms, the size of the scroll bar's thumb can be varied relative - * to the magnitude of the range of values it represents (that is, relative to - * the difference between its maximum and minimum values). Typically, this is - * used to indicate some proportional value such as the ratio of the visible - * area of a document to the total amount of space that it would take to display - * it. SWT supports setting the thumb size even if the underlying platform does - * not, but in this case the appearance of the scroll bar will not change. - *

- *

- * Scroll bars are created by specifying either H_SCROLL, - * V_SCROLL or both when creating a Scrollable. They - * are accessed from the Scrollable using - * getHorizontalBar and getVerticalBar. - *

- *

- * Note: Scroll bars are not Controls. On some platforms, scroll bars that - * appear as part of some standard controls such as a text or list have no - * operating system resources and are not children of the control. For this - * reason, scroll bars are treated specially. To create a control that looks - * like a scroll bar but has operating system resources, use Slider - * . - *

- *
- *
Styles:
- *
HORIZONTAL, VERTICAL
- *
Events:
- *
Selection
- *
- *

- * Note: Only one of the styles HORIZONTAL and VERTICAL may be specified. - *

Instances that do not have a parent (that is, - * they are built using the constructor, which takes a Display as - * the argument) are described as top level shells. Instances that do - * have a parent are described as secondary or dialog shells. - *

- * Instances are always displayed in one of the maximized, minimized or normal - * states: - *

    - *
  • - * When an instance is marked as maximized, the window manager will - * typically resize it to fill the entire visible area of the display, and the - * instance is usually put in a state where it can not be resized (even if it - * has style RESIZE) until it is no longer maximized.
    • - *
  • - * When an instance is in the normal state (neither maximized or - * minimized), its appearance is controlled by the style constants which were - * specified when it was created and the restrictions of the window manager (see - * below).
    • - *
  • - * When an instance has been marked as minimized, its contents (client - * area) will usually not be visible, and depending on the window manager, it - * may be "iconified" (that is, replaced on the desktop by a small simplified - * representation of itself), relocated to a distinguished area of the screen, - * or hidden. Combinations of these changes are also possible.
    • - *
- *

- *

- * The modality of an instance may be specified using style bits. The - * modality style bits are used to determine whether input is blocked for other - * shells on the display. The PRIMARY_MODAL style allows an - * instance to block input to its parent. The APPLICATION_MODAL - * style allows an instance to block input to every other shell in the display. - * The SYSTEM_MODAL style allows an instance to block input to all - * shells, including shells belonging to different applications. - *

- *

- * Note: The styles supported by this class are treated as HINTs, since - * the window manager for the desktop on which the instance is visible has - * ultimate control over the appearance and behavior of decorations and - * modality. For example, some window managers only support resizable windows - * and will always assume the RESIZE style, even if it is not set. In addition, - * if a modality style is not supported, it is "upgraded" to a more restrictive - * modality style that is supported. For example, if PRIMARY_MODAL - * is not supported, it would be upgraded to APPLICATION_MODAL. A - * modality style may also be "downgraded" to a less restrictive style. For - * example, most operating systems no longer support SYSTEM_MODAL - * because it can freeze up the desktop, so this is typically downgraded to - * APPLICATION_MODAL. - *

- *
Styles:
- *
BORDER, CLOSE, MIN, MAX, NO_TRIM, RESIZE, TITLE, ON_TOP, TOOL
- *
APPLICATION_MODAL, MODELESS, PRIMARY_MODAL, SYSTEM_MODAL
- *
Events:
- *
Activate, Close, Deactivate, Deiconify, Iconify
- *
- * Class SWT provides two "convenience constants" for the most - * commonly required style combinations: - *
- *
SHELL_TRIM
- *
- * the result of combining the constants which are required to produce a typical - * application top level shell: (that is, - * CLOSE | TITLE | MIN | MAX | RESIZE)
- *
DIALOG_TRIM
- *
- * the result of combining the constants which are required to produce a typical - * application dialog shell: (that is, TITLE | CLOSE | BORDER)

- * At any given moment, a given slider will have a single 'selection' that is - * considered to be its value, which is constrained to be within the range of - * values the slider represents (that is, between its minimum and - * maximum values). - *

- *

- * Typically, sliders will be made up of five areas: - *

    - *
  1. an arrow button for decrementing the value
    2. - *
  2. a page decrement area for decrementing the value by a larger amount
    3. - *
  3. a thumb for modifying the value by mouse dragging
    4. - *
  4. a page increment area for incrementing the value by a larger amount
    5. - *
  5. an arrow button for incrementing the value
    6. - *
- * Based on their style, sliders are either HORIZONTAL (which have - * a left facing button for decrementing the value and a right facing button for - * incrementing it) or VERTICAL (which have an upward facing button - * for decrementing the value and a downward facing buttons for incrementing - * it). - *

- *

- * On some platforms, the size of the slider's thumb can be varied relative to - * the magnitude of the range of values it represents (that is, relative to the - * difference between its maximum and minimum values). Typically, this is used - * to indicate some proportional value such as the ratio of the visible area of - * a document to the total amount of space that it would take to display it. SWT - * supports setting the thumb size even if the underlying platform does not, but - * in this case the appearance of the slider will not change. - *
