Example for showing save as dialog

[stefaneidelloth]

Please provide an extension example for showing a "Save as ..." dialog.

Thanks @stefaneidelloth for the suggestion.

Maybe this could be part of a more general dialog example that would also show other types of input dialogs:

@NoobMaster1999 You definitely can. Do you need pointers and/or suggestion?

[NoobMaster1999]

Yes please

Ok a story could be the following:

• Open a file test.example using getOpenFiles
  https://github.com/jupyterlab/jupyterlab/blob/0820455e14586e75b27fc2de80ce30683ce6d7a7/packages/filebrowser/src/opendialog.ts#L73
• Open the picked up file
• Click a ➕ toolbar button
• Prompts to pick up the type of value to enter using getItem
  The possible value will be boolean, number, text or password
  https://github.com/jupyterlab/jupyterlab/blob/0820455e14586e75b27fc2de80ce30683ce6d7a7/packages/apputils/src/inputdialog.ts#L146
• Prompts with the appropriate get... function for the value
• Add the value to the file
• Click a 💾 toolbar button
• Prompts with a save as dialog
  That dialog does not exists but we could extend getOpenFiles
• Save the file

Tip: start by duplicating the hello-world example (and renaming dialogs).

Example of interest:

• getOpenFile: https://github.com/fcollonval/jupyter-project/blob/91d208b729529b59d9a87f88c6977b46dd44e9c2/src/project.ts#L697
• getItem:

  extension-examples/state/src/index.ts

  Line 36 in 92e0814

  return InputDialog.getItem({

• getText:

  extension-examples/kernel-output/src/index.ts

  Line 97 in 92e0814

  const input = await InputDialog.getText({

Don't hesitate to open a draft PR early to get help.

Edited: remove toolbar buttons to simplify the example.

@fcollonval I just open a PR can you just review it?

[fcollonval]

I'm not sure to get where the PR was opened. Could you provide a link to it @NoobMaster1999 ?

Hey I was wondering if/how easy it would be have an InputDialog that requests several values rather than just one
