Detailed Description▲
The Matrix4x4 type provides a way to apply a transformation to an Item through a 4x4 matrix.
It allows for a combination of rotation, scale, translatation and shearing by using just one tranformation provided in a 4x4-matrix.
The following example rotates a Rectangle 45 degress (PI/4):
Sélectionnez
Rectangle {
width: 100
height: 100
color: "red"
transform: Matrix4x4 {
property real a: Math.PI / 4
matrix: Qt.matrix4x4(Math.cos(a), -Math.sin(a), 0, 0,
Math.sin(a), Math.cos(a), 0, 0,
0, 0, 1, 0,
0, 0, 0, 1)
}
}
