Color Triangle
A color selection widget based on the hue-saturation-value (HSV) color model.
The color space is presented as a triangle, making it easy for the user to find and select precisely the wanted color shade.These color widgets are particularly useful for developers of graphics, imaging, and visualization applications.
This Qt Solutions component is for Qt 3. For Qt 4 Solutions, please visit the Qt 4 Solutions Catalog.
