详细描述

The ColorGroup type is used to define a set of colors with certain roles. Although a ColorGroup has no visual appearance, it defines colors used to customize rendered items.

Default values of colors are equal to active group colors of default-constructed QPalette .

The following code can be used to create a color group with some colors specified:

ColorGroup {
    alternateBase: "red"
    base: "green"
}
