# Apply the complete dark theme to your Qt App.

Further information can be found in our docs:

• Usage Guide

Enable HiDPI

# enable_hi_dpi() must be called before the instantiation of QApplication.
qdarktheme.enable_hi_dpi()
app = QApplication(sys.argv)
qdarktheme.setup_theme()

For Qt6 bindings, HiDPI “just works” without using this function.

Light theme

qdarktheme.setup_theme("light")

Sync with OS's theme and accent

qdarktheme.setup_theme("auto")

On macOS, qdarktheme also syncs with accent colors.

Customizing colors

You can customize the theme color.

# Customize accent color.
qdarktheme.setup_theme(custom_colors={"primary": "#D0BCFF"})

For a list of all customizable colors, see the Theme Color Reference:

• Theme Color

Sharp frame

You can change the corner style.

# Default is "rounded".
stylesheet = qdarktheme.setup_theme(corner_shape="sharp")

QPalette and stylesheet

You can also only load QPalette and stylesheet. qdarktheme.setup_theme uses the following functions internally.

palette = qdarktheme.load_palette(theme="dark")
stylesheet = qdarktheme.load_stylesheet(theme="dark")

Example

To check all Qt widgets, run:

python -m qdarktheme.widget_gallery
