Wow, it just took me the better part of an hour to figure out how to pin a custom program to the taskbar with a custom icon! If the .exe doesn’t contain an application icon, the task bar icon is replaced by the default icon on exit.
Well, my program does contain an icon (it’s a QT App), but Winblows doesn’t care. Maybe because it’s a PNG instead of ICO, but who knows.
The Würgaround: create a shortcut for the executable, then right-click for properties and voila, there’s a “Change icon…” button! Change the icon to whatever, start the App via the shortcut and pin it to the taskbar!
This is wrong in so, so many ways… Don’t even get me started 🙁
