   Is your feature request related to a problem? Please describe. An option in settings to switch between light and dark theme. Will be great if it works on every OS like Electrum. However, created the issue specifically for ‘Windows’ because #68 (comment)

   Describe the solution you’d like

   

   Describe alternatives you’ve considered

   1. Workarounds for Linux: #68 (comment)
   2. Not use GUI

   Additional context I tried few things: #68 (comment). Worked partially for Linux but didn’t work on Windows.

   Also tried running master branch on Windows but there is no change in GUI.

   The issue has been resolved in https://github.com/bitcoin/bitcoin/pull/30997, as Qt 6.7.3 allows an app to use the dark system palette on Windows.

   The issue has been resolved in bitcoin/bitcoin#30997, as Qt 6.7.3 allows an app to use the dark system palette on Windows.

   Based on my testing, this only works on Windows 11 currently.

   To get it working on Windows 10, it would need the GUI to use one of the other Qt styles, other than what they have it default to for Windows 10, which is called the “windowsvista” style. See here: https://forum.qt.io/topic/163222/dark-color-scheme-on-windows-best-practises/2?_=1762948120656

   That link says that “Fusion” works. Also, after Qt 6.8.1, the “windows11” style will work, even on Windows 10. Not sure if the “windows” style might also work on Qt 6.7.3.

   For testing, I installed qBittorrent (another app that uses Qt), and it defaults to the “Fusion” style to get dark mode working in Windows 10. qBittorrent currently uses Qt 6.9.0, and a quick test of it shows that, indeed, using the “Fusion”, “windows”, or “windows11” styles all display in dark mode, while the “windowsvista” style does not.
