Hi everybody.
I'm trying to make a cheat sheet where the results of one/some steps are
used as inputs in others.
I'm having trouble finding the associated handlers for some commands in
order to figure out if those handlers return anything.
In particular, I'm trying to use

org.eclipse.ui.newWizard(newWizardId=org.eclipse.uml2.uml.ed itor.presentation.UMLModelWizardID)
org.eclipse.ui.file.import(importWizardId=org.eclipse.ui.wiz ards.import.FileSystem)

to name a few.
I wanted to know if: A) The "new UML Model" wizard command returns a
reference to the generated UML model (or its path, o smthg),
B) If the "Import File System" wizard
command returns a reference to the imported element.

Where is the correct place to look for such documentation?
(command<->handler correspondences or documentation on the command
(input parameters, returned objects, etc.)).
Best regards,
Juan Pedro

If commands return a parameter, then it should be identified in the
command definition (which you can see in the Plug-in Registry view). It
would include a returnTypeId which points to the commandParameterType
that the command can return.

AFAIK the default handlers for import
org.eclipse.ui.internal.handlers.WizardHandler.Import and new wizard
org.eclipse.ui.internal.handlers.WizardHandler.New don't return anything.

Thank you Paul for your answer..
Which way would you suggest to go to feed the resulting imported
file/new file into the next step in the cheatsheet?.
As you said, those commands don't return anything, so I can't use
neither parameters nor variables.
Is suggesting the user to select the file in the project explorer before
running the command and using "active selection" the correct way to go?.
Regards,
Juan Pedro

if they then select the new file in the explorer you could use the
"selection", or if creating the new file opened the editor you could use
the editor input of the activeEditor
