Adding a view to a perspective [message #329697]

Hi,

I have created an update to my RCP app that has added a view to a
perspective. If the app has not been run before (i.e. a clean install),
the view appears as I expect. However, if the app has been run before
(i.e it has been updated), then the new view does not appear (as the
stored perspectives 'state' does not contain the view). I can get the
view to appear by reseting the perspective.

I want to detect this situation (the update case) and issue a message to
the user that a new view is available and ask them if they want to
display it.

Does anybody have some ideas that will point me in the right direction
for implementing this?

Thanks,

To add a view to an already existing perspective you can use the
org.eclipse.ui.perspectiveExtensions extension point in your plugin.xml
where you can specify the perspective and the view you wish to add. But
doing this will add the view if not present (there won't be any prompts or
messages to the user). I am not sure how to do that (regarding giving the
user a message and then accordingly bringing the view up).

I don't really get your notion of the app getting updated when run once so
not sure what will really help you!

Hope the perspectiveExtensions helps,
Rahul

Rahul,

Thanks, but I already have a perspective extension that works.

My issue is this:
I already have a product that customers have installed. I am providing
an update to that product (via the Eclipse update mechanism). In this
update, I have added a new view to an existing perspective. This new
view does not appear until the customer does a "reset perspective". I
would like to automate this process, so that the users doesn't have to
do anything.

I can think of round-about ways to do it ... for example, when your
plugin starts up read all of the relevant perspectiveExtensions from the
IExtensionRegistry ... you can save the information you need in your
plugin state location.

Then if you startup and find the view not in your plugin state location
file, you know it has been added or removed.

Hi Derek,

I think the workaround suggested by Paul is a pretty neat way of doing what
you wish to achieve. If you have any other issue with the same, maybe you
could post that.

OK. Here is what I have done.

I have registered a perspectiveListener and registered it during my
earlyStartup:

public void perspectiveActivated(IWorkbenchPage page,
IPerspectiveDescriptor desc) {
if (isMyPerspective(desc)) {
// 'my' view should be in this perspective
Perspective persp = ((WorkbenchPage) page).getActivePerspective();
IViewReference[] refs = persp.getViewReferences();
if (!containsMyView(refs)) {
// 'my' view is not currently shown
if (queryShowView()) {
// user has agreed to show 'my' view
page.showView(MY_VIEW_ID);
}
}
}
}

This works, but I get a 'access restriction' on Perspective. Is there an
API way to do this?

Thanks,

You can use org.eclipse.ui.IWorkbenchPage.getViewReferences() ... it
will only return the view references for the active perspective.
