Remove Flashing Default Icon When Running Application

[petertzy]

When running the application, a default icon briefly flashes on the window. This icon comes from ttkbootstrap.

The goal is to remove or replace this icon. Potential approaches include:

1. Replace the ttkbootstrap default icon with an existing icon.icns.
2. Prevent ttkbootstrap from loading its built-in icon altogether.

Any guidance or suggestions on how to achieve this would be appreciated.

@petertzy Hey! I will like to take this up as my first contribution here.

Your application briefly shows the default ttkbootstrap icon before loading, which disrupts the user experience. I’ll modify the window initialization to either suppress the default icon entirely or replace it with your existing icon.icns by inspecting the ttkbootstrap source and overriding the icon handling directly in your code.

I’ve handled similar icon override issues in a Tkinter-based desktop tool where we replaced the default window icon with a custom .icns file, ensuring clean startup without flickers.

Next step: Share a minimal code snippet where the window is created or where ttkbootstrap is initialized so I can target the change precisely.
