public class ApplicationWindow extends Window implements IRunnableContext
An application window is a high-level "main window", with built-in support for an optional menu bar with standard menus, an optional toolbar, and an optional status line.Creating an application window involves the following steps:
- creating an instance of
ApplicationWindow - assigning the window to a window manager (optional)
- opening the window by calling
open
Only on the last step, when the window is told to open, are the window's shell and widget tree created. When the window is closed, the shell and widget tree are disposed of and are no longer referenced, and the window is automatically removed from its window manager. Like all windows, an application window may be reopened.
An application window is also a suitable context in which to perform long-running operations (that is, it implements
IRunnableContext).

protected Label getSeperator1()
Return the top seperator.- Returns:
- Label
-
addMenuBar
protected void addMenuBar()
Configures this window to have a menu bar. Does nothing if it already has one. This method must be called before this window's shell is created.
-
addStatusLine
protected void addStatusLine()
Configures this window to have a status line. Does nothing if it already has one. This method must be called before this window's shell is created.
-
addToolBar
protected void addToolBar(int style)
Configures this window to have a tool bar. Does nothing if it already has one. This method must be called before this window's shell is created.- Parameters:
style- swt style bits used to create the Toolbar- See Also:
ToolBarManager(int),for style bits
-

protected void addCoolBar(int style)
Configures this window to have a cool bar. Does nothing if it already has one. This method must be called before this window's shell is created.- Parameters:
style- the cool bar style- Since:
- 3.0
-
canHandleShellCloseEvent
protected boolean canHandleShellCloseEvent()
Description copied from class:WindowDetermines if the window should handle the close event or do nothing.The default implementation of this framework method returns
true, which will allow thehandleShellCloseEventmethod to be called. Subclasses may extend or reimplement.- Overrides:
canHandleShellCloseEventin classWindow- Returns:
- whether the window should handle the close event.
-
close
public boolean close()
Description copied from class:WindowCloses this window, disposes its shell, and removes this window from its window manager (if it has one).This framework method may be extended (
super.closemust be called).Note that in order to prevent recursive calls to this method it does not call
Shell#close(). As a resultShellListeners will not receive ashellClosedevent.
-
configureShell
protected void configureShell(Shell shell)
Extends the super implementation by creating the trim widgets usingcreateTrimWidgets.- Overrides:
configureShellin classWindow- Parameters:

-
getLayout
protected Layout getLayout()
Description copied from class:WindowCreates the layout for the shell. The layout created here will be attached to the composite passed into createContents. The default implementation returns a GridLayout with no margins. Subclasses that change the layout type by overriding this method should also override createContents.A return value of null indicates that no layout should be attached to the composite. In this case, the layout may be attached within createContents.
-

runin interfaceIRunnableContext- Parameters:
fork-trueif the runnable should be run in a separate thread, andfalseto run in the same threadcancelable-trueto enable the cancelation, andfalseto make the operation uncancellablerunnable- the runnable to run- Throws:
InvocationTargetException- wraps any exception or error which occurs while running the runnableInterruptedException- propagated by the context if the runnable acknowledges cancelation by throwing this exception. This should not be thrown if cancelable isfalse.
