| org.eclipse.ui.contexts.IWorkbenchContextSupport
All known Subclasses: org.eclipse.ui.internal.contexts.WorkbenchContextSupport,
| IWorkbenchContextSupport | | public interface IWorkbenchContextSupport (Code) | |
An instance of this interface provides support for managing contexts at the
IWorkbench level. This provides the functionality necessary to
enabled contexts, disable or enabled the key binding service, as well as
register shells as particular types of windows.
This interface is not intended to be extended or implemented by clients.

| Field Summary | |
| final public static String | CONTEXT_ID_DIALOG
The identifier for the context that is active when a shell registered as
a dialog. | | final public static String | CONTEXT_ID_DIALOG_AND_WINDOW
The identifier for the context that is active when a shell is registered
as either a window or a dialog. | | final public static String | CONTEXT_ID_WINDOW
The identifier for the context that is active when a shell is registered
as a window. | | final public static int | TYPE_DIALOG
The type used for registration indicating that the shell should be
treated as a dialog. | | final public static int | TYPE_NONE
The type used for registration indicating that the shell should not
receive any key bindings be default. | | final public static int | TYPE_WINDOW
The type used for registration indicating that the shell should be
treated as a window. |
| CONTEXT_ID_DIALOG | | final public static String CONTEXT_ID_DIALOG(Code) | | The identifier for the context that is active when a shell registered as
a dialog.
|
| CONTEXT_ID_DIALOG_AND_WINDOW | | final public static String CONTEXT_ID_DIALOG_AND_WINDOW(Code) | | The identifier for the context that is active when a shell is registered
as either a window or a dialog.
|
| CONTEXT_ID_WINDOW | | final public static String CONTEXT_ID_WINDOW(Code) | | The identifier for the context that is active when a shell is registered
as a window.
|
| TYPE_DIALOG | | final public static int TYPE_DIALOG(Code) | | The type used for registration indicating that the shell should be
treated as a dialog. When the given shell is active, the "In Dialogs"
context should also be active.
|
| TYPE_NONE | | final public static int TYPE_NONE(Code) | | The type used for registration indicating that the shell should not
receive any key bindings be default. When the given shell is active, we
should not provide any EnabledSubmission instances for the
"In Dialogs" or "In Windows" contexts.
|
| TYPE_WINDOW | | final public static int TYPE_WINDOW(Code) | | The type used for registration indicating that the shell should be
treated as a window. When the given shell is active, the "In Windows"
context should also be active.
|
| addEnabledSubmission | | void addEnabledSubmission(EnabledSubmission enabledSubmission)(Code) | |
Add a single enabled submission for consideration. An enabled submission
is a description of certain criteria under which a particular context
should become active. All added submissions will be check when the
conditions in the workbench change, and zero or more contexts will be
selected as active.
Just because an enabled submission is added, it does not mean that the
corresponding context will become active. The workbench will consider the
request, but other factors (such as conflicts) may prevent the context
from becoming active.
Parameters:
enabledSubmission - The enabled submission to be considered; must not benull. |
| addEnabledSubmissions | | void addEnabledSubmissions(Collection enabledSubmissions)(Code) | |
Adds zero or more enabled submissions for consideration. An enabled
submission is a description of certain criteria under which a particular
context should become active. All added submissions will be check when
the conditions in the workbench change, and zero or more contexts will be
selected as active.
Just because an enabled submission is added, it does not mean that the
corresponding context will become active. The workbench will consider the
request, but other factors (such as conflicts) may prevent the context
from becoming active.
Parameters:
enabledSubmissions - The enabled submissions to be considered; must not benull, but may be empty. Every element in thecollection must be an instance ofEnabledSubmission. |
| getContextManager | | IContextManager getContextManager()(Code) | | Returns the context manager for the workbench.
the context manager for the workbench. Guaranteed not to benull. |
| getShellType | | public int getShellType(Shell shell)(Code) | | Returns the shell type for the given shell.
Parameters:
shell - The shell for which the type should be determined. If thisvalue is null, thenIWorkbenchContextSupport.TYPE_NONE is returned. IWorkbenchContextSupport.TYPE_WINDOW,IWorkbenchContextSupport.TYPE_DIALOG, orIWorkbenchContextSupport.TYPE_NONE.

| isKeyFilterEnabled | | public boolean isKeyFilterEnabled()(Code) | | Tests whether the global key binding architecture is currently active.
true if the key bindings are active;false otherwise. |
| openKeyAssistDialog | | public void openKeyAssistDialog()(Code) | | Opens the key assistant dialog positioned near the key binding entry in
the status bar.

| registerShell | | public boolean registerShell(Shell shell, int type)(Code) | |
Registers a shell to automatically promote or demote some basic types of
contexts. The "In Dialogs" and "In Windows" contexts are provided by the
system. This a convenience method to ensure that these contexts are
promoted when the given is shell is active.
If a shell is registered as a window, then the "In Windows" context is
enabled when that shell is active. If a shell is registered as a dialog --
or is not registered, but has a parent shell -- then the "In Dialogs"
context is enabled when that shell is active. If the shell is registered
as none -- or is not registered, but has no parent shell -- then the
neither of the contexts will be enabled (by us -- someone else can always
enabled them).
If the provided shell has already been registered, then this method will
change the registration.
Parameters:
shell - The shell to register for key bindings; must not benull.
Parameters:
type - The type of shell being registered. This value must be one ofthe constants given in this interface. true if the shell had already been registered(i.e., the registration has changed); falseotherwise. |
| removeEnabledSubmission | | void removeEnabledSubmission(EnabledSubmission enabledSubmission)(Code) | |
Removes a single enabled submission from consideration. Only the same
enabled submission will be removed; equivalent submissions will not be
removed. Removing an enabled submission does not necessarily mean that
the corresponding context will become inactive. It is possible that other
parts of the application have requested that the context be enabled.
There is no way to disable a context. It is only possible to not enable
it.
Parameters:
enabledSubmission - The enabled submission to be removed; must not benull. |
| removeEnabledSubmissions | | void removeEnabledSubmissions(Collection enabledSubmissions)(Code) | |
Removes a collection of enabled submissions from consideration. Only the
same enabled submissions will be removed; equivalent submissions will not
be removed. Removing an enabled submission does not necessarily mean that
the corresponding context will become inactive. It is possible that other
parts of the application have requested that the context be enabled.
There is no way to disable a context. It is only possible to not enable
it.
Parameters:
enabledSubmissions - The enabled submissions to be removed; must not benull, but may be empty. The collection mustonly contain instances of EnabledSubmission. |
| setKeyFilterEnabled | | public void setKeyFilterEnabled(boolean enabled)(Code) | | Enables or disables the global key binding architecture. The architecture
should be enabled by default.
When enabled, keyboard shortcuts are active, and that key events can
trigger commands. This also means that widgets may not see all key events
(as they might be trapped as a keyboard shortcut).
When disabled, no key events will trapped as keyboard shortcuts, and that
no commands can be triggered by keyboard events. (Exception: it is
possible that someone listening for key events on a widget could trigger
a command.)
Parameters:
enabled - Whether the key filter should be enabled. |
| unregisterShell | | public boolean unregisterShell(Shell shell)(Code) | |
Unregisters a shell that was previously registered. After this method
completes, the shell will be treated as if it had never been registered
at all. If you have registered a shell, you should ensure that this
method is called when the shell is disposed. Otherwise, a potential
memory leak will exist.
If the shell was never registered, or if the shell is null,
then this method returns false and does nothing.
Parameters:
shell - The shell to be unregistered; does nothing if this value isnull. true if the shell had been registered;false otherwise. |
