Dark mode

in Ruby Scripting

Here is a nice script for those who love fancy "dark mode":


palette = RBA::QPalette::new

palette.setColorGroup(RBA::QPalette::Active, 
  RBA::QBrush::new(RBA::QColor::new("#f0f0f0")),   # windowText
  RBA::QBrush::new(RBA::QColor::new("#303030")),   # button
  RBA::QBrush::new(RBA::QColor::new("#505050")),   # light
  RBA::QBrush::new(RBA::QColor::new("#707070")),   # dark
  RBA::QBrush::new(RBA::QColor::new("#909090")),   # mid
  RBA::QBrush::new(RBA::QColor::new("#e0e0e0")),   # text
  RBA::QBrush::new(RBA::QColor::new("#909090")),   # brightText
  RBA::QBrush::new(RBA::QColor::new("#202020")),   # base
  RBA::QBrush::new(RBA::QColor::new("#101010")),   # window
) 

palette.setColorGroup(RBA::QPalette::Inactive, 
  RBA::QBrush::new(RBA::QColor::new("#f0f0f0")),   # windowText
  RBA::QBrush::new(RBA::QColor::new("#303030")),   # button
  RBA::QBrush::new(RBA::QColor::new("#505050")),   # light
  RBA::QBrush::new(RBA::QColor::new("#707070")),   # dark
  RBA::QBrush::new(RBA::QColor::new("#909090")),   # mid
  RBA::QBrush::new(RBA::QColor::new("#e0e0e0")),   # text
  RBA::QBrush::new(RBA::QColor::new("#909090")),   # brightText
  RBA::QBrush::new(RBA::QColor::new("#202020")),   # base
  RBA::QBrush::new(RBA::QColor::new("#101010")),   # window
) 

palette.setColorGroup(RBA::QPalette::Disabled, 
  RBA::QBrush::new(RBA::QColor::new("#808080")),   # windowText
  RBA::QBrush::new(RBA::QColor::new("#303030")),   # button
  RBA::QBrush::new(RBA::QColor::new("#505050")),   # light
  RBA::QBrush::new(RBA::QColor::new("#606060")),   # dark
  RBA::QBrush::new(RBA::QColor::new("#686868")),   # mid
  RBA::QBrush::new(RBA::QColor::new("#707070")),   # text
  RBA::QBrush::new(RBA::QColor::new("#686868")),   # brightText
  RBA::QBrush::new(RBA::QColor::new("#202020")),   # base
  RBA::QBrush::new(RBA::QColor::new("#101010")),   # window
) 

RBA::QApplication::setPalette(palette)

Set the "run on startup" flag and enjoy night mode:

    Hi Matthias,

    Thanks a lot for the "dark mode" script! Personally, I prefer to use "dark mode" whenever it is available.

    I noticed two things:

    1) The top bar of the main window (with the menus) and the top bar of the layout panel(s) seem to stay "light" in my case and the menu names are hardly readable...

    2) The "Macro Development" window still has quite some "light" sub areas and the names of the folders and files in the "Local" map are hardly readable...

    Maybe it is related to the the KLayout version, 0.28 <> 0.27.9?

    Cheers,

    Tomas

    Ok, I need to say that was a first shot :)

    I understand that Qt borrows parts of the styling from the underlying system. On Windows that's probably tab widgets and similar. I guess the way to do that properly is to use Qt style sheets rather simply changing the palette.

    On Linux however, the script works rather nicely. Some icons are hard to see, but as I said - that's a first shot only.

    Your approach is excellent. I referenced your code and made modifications using GPT, and now it works very well on Windows systems too.

    app = RBA::QApplication::instance
return if app.nil?

RBA::QApplication::setStyle("Fusion")

palette = RBA::QPalette::new

[:Active, :Inactive].each do |state|
  palette.setColorGroup(
    RBA::QPalette.const_get(state),

    RBA::QBrush::new(RBA::QColor::new("#ffffff")), # windowText
    RBA::QBrush::new(RBA::QColor::new("#2d2d30")), # button
    RBA::QBrush::new(RBA::QColor::new("#3e3e42")), # light
    RBA::QBrush::new(RBA::QColor::new("#1e1e1e")), # dark
    RBA::QBrush::new(RBA::QColor::new("#2a2a2a")), # mid
    RBA::QBrush::new(RBA::QColor::new("#e6e6e6")), # text
    RBA::QBrush::new(RBA::QColor::new("#ffffff")), # brightText
    RBA::QBrush::new(RBA::QColor::new("#1e1e1e")), # base
    RBA::QBrush::new(RBA::QColor::new("#1e1e1e"))  # window
  )
end

palette.setColorGroup(
  RBA::QPalette::Disabled,

  RBA::QBrush::new(RBA::QColor::new("#7a7a7a")), # windowText
  RBA::QBrush::new(RBA::QColor::new("#2d2d30")), # button
  RBA::QBrush::new(RBA::QColor::new("#3a3a3a")), # light
  RBA::QBrush::new(RBA::QColor::new("#1a1a1a")), # dark
  RBA::QBrush::new(RBA::QColor::new("#2a2a2a")), # mid
  RBA::QBrush::new(RBA::QColor::new("#8a8a8a")), # text
  RBA::QBrush::new(RBA::QColor::new("#7a7a7a")), # brightText
  RBA::QBrush::new(RBA::QColor::new("#1e1e1e")), # base
  RBA::QBrush::new(RBA::QColor::new("#1e1e1e"))  # window
)

RBA::QApplication::setPalette(palette)

    Below is the result of using Klayout 0.30.4 on my Windows 11 system.
