Class WorkbenchHelp
java.lang.Object
org.eclipse.ui.help.WorkbenchHelp
Deprecated. clients should use IWorkbenchHelpSystem
instead
-
public class WorkbenchHelp
- extends
Object
Provides methods for accessing the help UI.
The help UI is optional, to allow applications to be configured
without one.
The various setHelp
methods allow context help to be hooked in
to SWT menus, menu items, and controls, and into JFace actions. This involves
furnishing a help context id. When the user requests help for one of the
established widgets (for instance, by hitting F1), the context id is
retrieved and passed to the help UI using
WorkbenchHelp.displayContext(helpContext, xposition, yposition)
.
In cases more dynamic situations, clients may hook their own help listener
and call WorkbenchHelp.displayContext
with an
IContext
.
This class provides static methods only; it is not intended to be instantiated
or subclassed.

displayContext
public static void displayContext(
IContext context,
int x,
int y)
-
Deprecated.
- Displays context-sensitive help for the given context.
(x,y) coordinates specify the location where the context sensitive
help UI will be presented. These coordinates are screen-relative
(ie: (0,0) is the top left-most screen corner).
The platform is responsible for calling this method and supplying the
appropriate location.
Ignored if no help UI is available.
-
-
Parameters:
-
context
- the context to display -
x
- horizontal position -
y
- verifical position -
Since:
- 3.0
displayHelpResource
public static void displayHelpResource(
String href)
-
Deprecated.
- Displays help content for the help resource with the given URL.
This method is called by the platform to launch the help system UI, displaying
the documentation identified by the href
parameter.
The help system makes no guarantee that all the help resources can be displayed or how they are displayed.
Ignored if no help UI is available.
-
-
Parameters:
-
href
- the URL of the help resource.
Valid href are as described in
IHelpResource.getHref()
-
Since:
- 3.0
