How to call forward / back manually? [message #303402]

How can I call forward and back actions manually from code? I want to
create my own buttons for those actions into a view and all I want is to
forward the action handling to the eclipse platform. I just can't seem
to find proper places in API to do this.

Thanks.

It's good if you can find the commands for these actions, usually by
command ID.

In 3.2:
ICommandService service=getSite().getService(ICommandService.class);
Command cmd = service.getCommand(FORWARD_ID).
if (cmd.isDefined()) {
cmd.executeWithChecks(new ExecutionEvent());
}

In 3.1.2, you can get the ICommandService from IWorkbench, either
getService() or getAdapter().

As for finding the ID, you can search through the Plug-in Registry view
or import binary plugins with linked content and search through the
plugin.xml yourself. The extension is org.eclipse.ui.commands

Thanks Paul.
I got it working using "org.eclipse.ui.navigate.backwardHistory" as back
and "org.eclipse.ui.navigate.forwardHistory" as forward. But I wasn't
able to find any constants for those.

That's OK, often there are no constants for actions that weren't
specifically designed to be used by client code.
