I've found the Qt documentation for QFileDialog and similar things, but all the references I've found discuss opening existing files or saving your current file. I haven't found anything that states how to actually create a new file, i.e. a new instance of your application.

I'm creating a character record sheet for a game. Since it's possible for one person to have multiple characters, especially if the game master wants to have many NPCs, having the ability to use File->New Character would be useful.

In summary, if the application is open with a character sheet, how would I call the code to create a new character sheet? I am using PyQt5 and the character sheet is created w/ QtDesigner.
