Examples of org.eclipse.jface.action.IStatusLineManager

org.eclipse.jface.action.IStatusLineManager
The IStatusLineManager interface provides protocol for displaying messages on a status line, for monitoring progress, and for managing contributions to the status line.
Note: An error message overrides the current message until the error message is cleared.
This package also provides a concrete status line manager implementation, {@link StatusLineManager StatusLineManager}.

    public static void setStatusBarMessage( final IToolContext context, final String message ) {
        context.updateUI(new Runnable(){
            public void run() {
                if (context.getActionBars() == null)
                    return;
                IStatusLineManager bar = context.getActionBars().getStatusLineManager();
                if (bar != null) {
                    bar.setMessage(message);
                    bar.setErrorMessage(null);
                }
            }
        });
