Method Documentation

void addColorStop(real offset, string color)

Adds a color stop with the given color to the gradient at the given offset. 0.0 is the offset at one end of the gradient, 1.0 is the offset at the other end.

For example:

const gradient = ctx.createConicalGradient(100, 100, Math.PI / 2);
gradient.addColorStop(0.0, Qt.rgba(1, 0, 0, 1));
gradient.addColorStop(0.5, "#ff8040");
gradient.addColorStop(1.0, "red");

real angle()

Returns the start angle of conical gradient in radians.

See also setAngle().

point centerPosition()

Returns the center point of conical gradient.

See also setCenterPosition().

void setAngle(real angle)

Sets the start angle of conical gradient to angle in radians. The angle starts from a line going horizontally right from the center, and proceeds clockwise.

See also angle().

void setCenterPosition(real x, real y)

Sets the center point of conical gradient to ( x, y).

See also centerPosition().

void setCenterPosition(point center)

Sets the center point of conical gradient to center.
