If someone with interest and good knowledge of the v2 classes, feel free to extends this into AHK's "class Gui" so its easy to use for others.
You can easy toggle between DarkMode and the Default Theme while the GUI is running. (Try this code and toggle with the radio button)
No need to manually adjust font colors or backgrounds when creating the GUI.
Todo:
- Font color of LV_Header
- ListView Scrollbars needs some workarounds (https://gist.github.com/ericoporto/1745f4b912e22f9eabfce2c7166d979b#dark-scrollbars)
- Font color of Checkboxes and Radios (atm I use a "fake" one - create controls without text and create a separat text control)
- Check more controls
Code: Select all
