Detailed Description

Represents the corner radii for a rectangular material-design shape.

CornersGroup stores four independent corner radii (top-left, top-right, bottom-left, bottom-right) used to describe the rounded corners of a shape. Radii are expressed in the framework's logical units (qreal) and may be converted to a QVector4D for GPU/paint operations or uniform uploads.

The class is lightweight, trivially copyable, and all accessor and mutator operations are noexcept.

Usage notes:

• Use setRadius() to set a uniform radius on all corners.
• radius() returns the maximum of the four corner values — useful when a single conservative inset or bound is required.
• toVector4D() / operator QVector4D() return the corner radii packed as a QVector4D in the order: (top-left, top-right, bottom-left, bottom-right).

Threading:

• Instances are not internally synchronized. Concurrent access must be externally synchronized if mutations may occur.

Examples:

// uniform rounded rectangle
Fluid::CornersGroup u(4.0);
 
// different radii
Fluid::CornersGroup c(5.0, 3.0, 4.0, 2.0);
 
// upload to shader as vec4: (tl, tr, bl, br)
QVector4D v = c.toVector4D();
