enum QPlatformServices::Capability

Capabilities are used to determine a specific platform service's availability.

ConstantValueDescription
QPlatformServices::ColorPickingFromScreen?The platform natively supports color picking from screen. This capability indicates that the platform supports "opaque" color picking, where the platform implements a complete user experience for color picking and outputs a color. This is in contrast to the application implementing the color picking user experience (taking care of showing a cross hair, instructing the platform integration to obtain the color at a given pixel, etc.). The related service function is pickColor().
