How to open an editor in createInitialLayout [message #447557]

Hi,

I am developing a RCP with a view and a editor as the initial perspective.

I add a view to the initial perspective in the createInitialLayout method:
------------------------------------------------------------ ------------------
IFolderLayout tl = layout.createFolder("tl", IPageLayout.LEFT, 0.28f,
editorArea);
tl.addView("views");
------------------------------------------------------------ ------------------

I add an editor in the createInitialLayout method using the following-
------------------------------------------------------------ ------------------
IWorkbenchPage page =
PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActi vePage();
page.openEditor(input, "Editor");
------------------------------------------------------------ ------------------

The problem that I am facing is the "page is null" when I run this as an
RCP.
As expected, this works when I run as part of the Eclipse workbench and
not as a product. How do I get around this issue?

Thanks in advance.

Regards,
Ravi

Hi,

The article "Inside the Workbench, A guide to the workbench internals"
quotes the following -
"The page owns a set of perspectives. Perspectives contain a layout and
information about what action sets to enable. Although perspectives appear
to contain views and the editor area, they only own a layout."

Shouldn't the page be created before the createInitialLayout method of the
Perspective class?

Ravi

Actually it's the opposite, createInitialLayout() is filling in layout
data. That's not tied to a page, but must be used by the perspective in
a page to create the page layout.

createInitialLayout() will almost always be called before page creation
on startup.

Layout is responsible for where the editor area shows up, not what
editors are open.

What about attaching a perspective listener to the workbench window.
Check when your perspective is opened, and open the editor then.

Hi Paul,

Thanks for the reply.
I tried attaching a perspective listener to the workbench window. The
addPerspectiveListener method doesn't have a return value. I cannot check
if my perspective is opened and hence cannot open the editor. Any
suggestions?

When does the page get created? I understand that createInitialLayout
defines the layout of a perspective. To display a perspective you need a
page. Any ideas what is the sequence?

Ravi

Sorry, why didn't you just listen for the perspectiveOpened() event?
Check out IPerspectiveListener/2/3/4

The page gets created and then the perspective gets created in the page.
The createInitialLayout() can happen any time before the perspective
gets created. Some of them never get called, since they only get
instantiated when someone tries to open their perspective.

Hi Paul,

Many thanks for your prompt response.

I have resolved this issue by opening the editor in the postWindowOpen
method. The page would have got created by the time this method gets
called.

Ravi
