How to capture before launch event?

[ghost]

Though I'm asking, I may already have this, maybe I just need a confirmation: I can do this through main.rs right? Before launching any window.

Context

Take Windows' sticky notes for example. I have a "main" window (where the sticky notes are listed) and children (notes windows) launched from this window (with WebViewWindow).

I would store the last opened notes windows somewhere, and when the user launches a new instance from a fresh start (no previous window opened), it would launch these opened notes directly. It is possible doing this through main.rs, right?

[ghost]

The reason I'm asking this, is because Windows' Sticky Note app launches the main window and then opens the last opened sticky notes, and finally closes the "main" window. I don't want this.

The .setup hook on the Builder is probably your best bet.
Don't set any windows in tauri.conf and create them in setup.

Thank you, I'll try this.
