Class ApplicationWindow
- All Implemented Interfaces:
IRunnableContext
,IShellProvider
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
).

does not block.- Parameters:
parentShell
- the parent shell, ornull
to create a top-level shell
-
-
Method Details
-
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:
-

- 3.0
-
canHandleShellCloseEvent
protected boolean canHandleShellCloseEvent()Description copied from class:Window
Determines if the window should handle the close event or do nothing.The default implementation of this framework method returns
true
, which will allow thehandleShellCloseEvent
method to be called. Subclasses may extend or reimplement.- Overrides:
canHandleShellCloseEvent
in classWindow
- Returns:
- whether the window should handle the close event.
-
close
public boolean close()Description copied from class:Window
Closes this window, disposes its shell, and removes this window from its window manager (if it has one).This framework method may be extended (
super.close
must be called).Note that in order to prevent recursive calls to this method it does not call
Shell#close()
. As a resultShellListener
s will not receive ashellClosed
event. -
configureShell
Extends the super implementation by creating the trim widgets usingcreateTrimWidgets
.- Overrides:
configureShell
in classWindow
- Parameters:
shell
- the shell
-
createTrimWidgets
Creates the trim widgets around the content area.- Parameters:
shell
- the shell- Since:
- 3.0
-
getLayout
Description copied from class:Window
Creates 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.
-

run
public void run(boolean fork, boolean cancelable, IRunnableWithProgress runnable) throws InvocationTargetException, InterruptedException This implementation of IRunnableContext#run(boolean, boolean, IRunnableWithProgress) blocks until the runnable has been run, regardless of the value offork

is set to true in most cases. Iffork
is set tofalse
, the runnable will run in the UI thread and it is the runnable's responsibility to callDisplay.readAndDispatch()
to ensure UI responsiveness.- Specified by:
run
in interfaceIRunnableContext

fork
-true

to enable the cancelation, andfalse
to 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
.
