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: *

*

* 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, 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. *
