- All Known Implementing Classes:
WorkbenchConfigurer
Note that these objects are only available to the main application (the plug-in that creates and owns the workbench).
This interface is not intended to be implemented by clients.

Method Details
-
getWorkbench
IWorkbench getWorkbench()Returns the underlying workbench.- Returns:
- the workbench
-
getSaveAndRestore
boolean getSaveAndRestore()Returns whether the workbench state should be saved on close and restored on subsequent open.The initial value is
false
.- Returns:
true
to save and restore workbench state, orfalse
to forget current workbench state on close.
-
setSaveAndRestore
void setSaveAndRestore(boolean enabled) Sets whether the workbench state should be saved on close and restored on subsequent open.- Parameters:
enabled
-true
to save and restore workbench state, orfalse
to forget current workbench state on close.
-
restoreWorkbenchWindow
Restores a workbench window from the given memento.- Parameters:
memento
- the memento from which to restore the window's state- Returns:
- the configurer for the restored window
- Throws:
WorkbenchException
- if an error occurred during the restore- Since:
- 3.1
- See Also:
-
getWorkbenchWindowManager
WindowManager getWorkbenchWindowManager()Returns the workbench window manager.- Returns:
- the workbench window manager Note:IWorkbenchWindow is implemented using JFace's Window (and therefore uses WindowManager), but this is an implementation detail
-
declareImage
Declares a workbench image.The workbench remembers the given image descriptor under the given name, and makes the image available to plug-ins via
IWorkbench.getSharedImages()
. For "shared" images, the workbench remembers the image descriptor and will manages the image object create from it; clients retrieve "shared" images viaISharedImages.getImage()
. For the other, "non-shared" images, the workbench remembers only the image descriptor; clients retrieve the image descriptor viaISharedImages.getImageDescriptor()
and are entirely responsible for managing the image objects they create from it. (This is made confusing by the historical fact that the API interface is called "ISharedImages".)- Parameters:
symbolicName
- the symbolic name of the imagedescriptor
- the image descriptorshared
-true
if this is a shared image, andfalse
if this is not a shared image- See Also:
-
emergencyClose
void emergencyClose()Forces the workbench to close due to an emergency. This method should only be called when the workbench is in dire straights and cannot continue, and cannot even risk a normal workbench close (think "out of memory" or "unable to create shell"). When this method is called, an abbreviated workbench shutdown sequence is performed (less critical steps may be skipped). The workbench advisor is still called; however, it must not attempt to communicate with the user. While an emergency close is in progress,emergencyClosing
returnstrue
. Workbench advisor methods should always check this flag before communicating with the user.- See Also:
-
emergencyClosing
boolean emergencyClosing()Returns whether the workbench is being closed due to an emergency. When this method returnstrue
, the workbench is in dire straights and cannot continue. Indeed, things are so bad that we cannot even risk a normal workbench close. Workbench advisor methods should always check this flag before attempting to communicate with the user.- Returns:
true
if the workbench is in the process of being closed under emergency conditions, andfalse
otherwise
-
getWindowConfigurer
Returns an object that can be used to configure the given window.- Parameters:
window
- a workbench window- Returns:
- a workbench window configurer
-
getData
Returns the data associated with the workbench at the given key.- Parameters:
key
- the key- Returns:
- the data, or
null
if there is no data at the given key
-
setData
Sets the data associated with the workbench at the given key.- Parameters:
key
- the keydata
- the data, ornull
to delete existing data
-
restoreState
IStatus restoreState()Restores the workbench state saved from the previous session, if any. This includes any open windows and their open perspectives, open views and editors, layout information, and any customizations to the open perspectives.This is typically called from the advisor's
openWindows()
method.- Returns:
- a status object indicating whether the restore was successful
- See Also:
-
openFirstTimeWindow
void openFirstTimeWindow()Opens the first time window, using the default perspective and default page input.This is typically called from the advisor's
openWindows()
method.- See Also:
-
getExitOnLastWindowClose
boolean getExitOnLastWindowClose()Returnstrue
if the workbench should exit when the last window is closed,false
if the window should just be closed, leaving the workbench (and its event loop) running.If
true
, the last window's state is saved before closing, so that it will be restored in the next session. This applies only ifgetSaveAndRestore()
) returnstrue
.If
false
, the window is simply closed, losing its state.If the workbench is left running, it can be closed using
IWorkbench.close()
, or a new window can be opened usingIWorkbench.openWorkbenchWindow(String, IAdaptable)
.The initial value is
true
.- Returns:
true
if the workbench will exit when the last window is closed,false
if the window should just be closed- Since:
- 3.1
-
setExitOnLastWindowClose
void setExitOnLastWindowClose(boolean enabled) Sets whether the workbench should exit when the last window is closed, or whether the window should just be closed, leaving the workbench (and its event loop) running.For more details, see
getExitOnLastWindowClose()
.- Parameters:
enabled
-true
if the workbench should exit when the last window is closed,false
if the window should just be closed- Since:
- 3.1
