This is a complete (I think) dark color palette for the Qt 5 Fusion theme, as well as a nice style sheet for the tool tips that make them blend better with the rest of the theme. To have immediate effect, be sure to put this in your main function before showing the parent window. Child windows should automatically inherit the palette unless you …

Qt 5 Dark Fusion Palette

    qApp->setStyle(QStyleFactory::create("Fusion"));

    QPalette darkPalette;
    darkPalette.setColor(QPalette::Window, QColor(53,53,53));
    darkPalette.setColor(QPalette::WindowText, Qt::white);
    darkPalette.setColor(QPalette::Base, QColor(25,25,25));
    darkPalette.setColor(QPalette::AlternateBase, QColor(53,53,53));
    darkPalette.setColor(QPalette::ToolTipBase, Qt::white);
    darkPalette.setColor(QPalette::ToolTipText, Qt::white);
    darkPalette.setColor(QPalette::Text, Qt::white);
    darkPalette.setColor(QPalette::Button, QColor(53,53,53));
    darkPalette.setColor(QPalette::ButtonText, Qt::white);
    darkPalette.setColor(QPalette::BrightText, Qt::red);
    darkPalette.setColor(QPalette::Link, QColor(42, 130, 218));

    darkPalette.setColor(QPalette::Highlight, QColor(42, 130, 218));
    darkPalette.setColor(QPalette::HighlightedText, Qt::black);
    
    qApp->setPalette(darkPalette);

    qApp->setStyleSheet("QToolTip { color: #ffffff; background-color: #2a82da; border: 1px solid white; }");

Screenshot please!

Looks great!

Thank you

Wow! This is great stuff. The only thing that isn't perfect out of the box is that deactivated buttons look the same as clickable ones. Otherwise - love it.

beautiful :))

darkPalette.setColor(QPalette::ToolTipBase, Qt::white);
darkPalette.setColor(QPalette::ToolTipText, Qt::white);

Why do you set both as white and then add qApp->setStyleSheet("QToolTip { color: #ffffff; background-color: #2a82da; border: 1px solid white; }"); ?

Very cool! One thing I spotted was that tab control are a bit black-on-black... Would be nice if the tabs themselves could be shaded a bit differently.

In my repo you can find similar palette and addition some stylesheets to make everything look dark, sexy and great 😃

This is exactly what I was looking for and it's hella easy to implement, thanks!

Look great~
Thank you ;)

This one doesn't handle disabled text (everything will appear enabled). Jorgen-VikingGod's appears to handle disabled controls properly.

Yeah, but this is a color palette, and the one you refer is a "skin".
So, people that look for a color palette, needs to add colors for disabled controls and text.

How can one add palette for disabled controls to qtquickcontrols2.conf? Or is this done in some other way?

Nice! I use this for my Qt dark theme example of a text editor.

Hi, ok, quick question... I got the dark theme working and all but I got this annoying white border, like 1-2px wide. Currently I'm looking at Jorgen-VikingGod's example trying to figure out exactly what is the property that disables that border but maybe someone can enlighten me. Thanks !
