How can i use modal window in the theia widget?

[discobot]

Such as the window to new a file in the EXPLORER. Are there any API to use? An example would be perfect. Thank you.

Modals are actually called Dialogs in the framework, one example is the SingleTextInputDialog and can be triggered like so:
