Hi,
I'm trying to customize the layout of a workbench to include an image and
other stuff. So far I managed to override the method
"createWindowContents(Shell)" from the WorkbenchWindowAdvisor class and had
success in changing the place of the toolbar and create a label with an
image. Now I'm trying to place the PerspectiveBar but without success it
always gives me the following exception:
java.lang.NullPointerException
at
org.eclipse.ui.internal.PerspectiveSwitcher.createControlFor Location(Unknown
Source)
at
org.eclipse.ui.internal.PerspectiveSwitcher.setPerspectiveBa rLocation(Unknown
Source)
at org.eclipse.ui.internal.PerspectiveSwitcher.createControl(Un known Source)
Here is part of my code:
@Override
public void createWindowContents(final Shell shell) {
final IWorkbenchWindowConfigurer configurer = getWindowConfigurer();
final WorkbenchWindow window = (WorkbenchWindow) configurer.getWindow();
final Workbench workbench = (Workbench) window.getWorkbench();
shell.setLayout(new GridLayout(2, false));
...
CBanner pbar = new CBanner(shell, SWT.NONE);
pbar.setLayoutData(new GridData(SWT.LEFT, SWT.CENTER, false, false, 2,
1));
PerspectiveSwitcher perspectiveSwitcher = new PerspectiveSwitcher(window,
pbar, SWT.FLAT | SWT.WRAP | SWT.RIGHT | SWT.HORIZONTAL);
perspectiveSwitcher.createControl(shell);
...
}
If anyone can help me out I would apreciate. Thanks
Tiago

Hi Tiago,
first: Use internal stuff at your own risk. Neither Workbench,
WorkbenchWindow nor PerspectiveSwitcher are API (as in RCP).
The NPE is caused as you are calling methods without setting up the
enviroment correctly first. Please take a look at the workbench code
(WorkbenchWindowAdvisor etc) how this is done.
In RCP you will get the same exception with your code. Normally you
would set the according preference to modify location of the perspective
switcher which is (sorry) not yet possible with RAP.

Hi,
Thanks for your reply. I'm going to do a little more investigation on the
workbench code. Meanwhile I got around the problem by implementing my own
toolbar and populating it with entries in the perspective registry.
Thanks.
