vector2d QML Basic Type
A vector2d type has x and y attributes, otherwise it is similar to the vector3d type. Please see the documentation about the vector3d type for more information.
To create a vector2d value, specify it as a "x,y" string, or define the components individually, or compose it with the Qt.vector2d() function.
The vector2d type has the following idempotent functions which can be invoked in QML:
| Function Signature | Description | Example | 
|---|---|---|
| real dotProduct(vector2d other) | Returns the scalar real result of the dot product of thisvector2d with theothervector2d | var a = Qt.vector2d(1,2); var b = Qt.vector2d(3,4); var c = a.dotProduct(b); console.log(c); // 11 | 
| vector2d times(vector2d other) | Returns the vector2d result of multiplying thisvector2d with theothervector2d | var a = Qt.vector2d(1,2); var b = Qt.vector2d(3,4); var c = a.times(b); console.log(c.toString()); // QVector2D(3, 8) | 
| vector2d times(real factor) | Returns the vector2d result of multiplying thisvector2d with the scalarfactor | var a = Qt.vector2d(1,2); var b = 4.48; var c = a.times(b); console.log(c.toString()); // QVector2D(4.48, 8.96) | 
| vector2d plus(vector2d other) | Returns the vector2d result of the addition of thisvector2d with theothervector2d | var a = Qt.vector2d(1,2); var b = Qt.vector2d(3,4); var c = a.plus(b); console.log(c.toString()); // QVector2D(4, 6) | 
| vector2d minus(vector2d other) | Returns the vector2d result of the subtraction of othervector2d fromthisvector2d | var a = Qt.vector2d(1,2); var b = Qt.vector2d(3,4); var c = a.minus(b); console.log(c.toString()); // QVector2D(-2, -2) | 
| vector2d normalized() | Returns the normalized form of thisvector | var a = Qt.vector2d(1,2); var b = a.normalized(); console.log(b.toString()); // QVector2D(0.447214, 0.894427) | 
| real length() | Returns the scalar real value of the length of thisvector2d | var a = Qt.vector2d(1,2); var b = a.length(); console.log(b.toString()); // 2.23606797749979 | 
| vector3d toVector3d() | Returns the vector3d result of converting thisvector2d to a vector3d | var a = Qt.vector2d(1,2); var b = a.toVector3d(); console.log(b.toString()); // QVector3D(1, 2, 0) | 
| vector4d toVector4d() | Returns the vector4d result of converting thisvector2d to a vector4d | var a = Qt.vector2d(1,2); var b = a.toVector4d(); console.log(b.toString()); // QVector4D(1, 2, 0, 0) | 
| bool fuzzyEquals(vector2d other, real epsilon) | Returns true if thisvector2d is approximately equal to theothervector2d. The approximation will be true if each attribute ofthisis withinepsilonofother. Note thatepsilonis an optional argument, the defaultepsilonis 0.00001. | var a = Qt.vector2d(1,2); var b = Qt.vector2d(1.0001, 1.9998); var c = a.fuzzyEquals(b); // default epsilon var d = a.fuzzyEquals(b, 0.005); // supplied epsilon console.log(c + " " + d); // false true | 
This basic type is provided by the QtQuick import.
