Alternative ways of starting a gef editor [message #93226]

Dear all,

I have created a gef editor which is currrently started by double clicking
on a particular file type and extension. The editor does not persist the
diagram or anything like that, therefore the file used to start the editor
is purely there as a bootstrap.

What are the alternate ways to start the editor? Is it possible to have the
editor start by a toolbar button or double clicking on a user defined
element in a jface tree viewer? I am trying to get away from the file aspect
of starting an editor and in particular a gef editor.

Many thanks for your help - this ng is a saviour at times!

You can open editor at any time by calling method IWorkbenchPage.openEditor
There are many overloaded methods, most probably you need
(IEditorInput input, String editorId).
Here are two utility methods for accesing IWorkbenchPage.

public IWorkbench getWorkbench() {
return PlatformUI.getWorkbench();
}
public IWorkbenchPage getActivePage() {
IWorkbenchWindow window= getWorkbench().getActiveWorkbenchWindow();
if (window == null)
return null;
return getWorkbench().getActiveWorkbenchWindow().getActivePage();
}

Many thanks for the response. In the end I created a a NullEditorInput and
passed that to the openEditor() method. I have also created an action on a
toolbar to kick it all off.

I take it that the IEditorInput is a proxy for the thing which represents
the persisted version of the diagram? Getting the IPersistableElement is
actually like getting a file or a connection to a database or a serialized
version then ...?

Thanks for the quick response.

I think IEditorInput is just want do you want. This is your GEF editor, so
you are free to create any implementation of IEditorInput that provides info
needed for you editor.
