I just noticed that we released a technote describing some undocumented methods of the MDialogBox component included with the Central SDK.

The updated methods include:

• MDialogBox.doOpen()
• MDialogBox.setIsModal()
• MDialogBox.doClose()
• MDialogBox.configureModalDialog()

You can read the entire technote here.

FYI, we are also writing a more extensive article for the Central DevNet center on how to use the component.
