/**
* Instances of this class represent the "windows"
* which the desktop or "window manager" is managing.
* 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_MOVE, NO_TRIM, RESIZE, TITLE, ON_TOP, TOOL, SHEET
* - 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
)
*
*
*
* Note: Only one of the styles APPLICATION_MODAL, MODELESS,
* PRIMARY_MODAL and SYSTEM_MODAL may be specified.
*
* IMPORTANT: This class is not intended to be subclassed.
