The
Qt Quick
模块提供图形图元类型。这些类型仅在 QML 文档中可用，若该文档导入
QtQuick
名称空间。
当前版本的
QtQuick
module is version 12, and thus it may be imported via the following statement:
import QtQuick 2.12

Qt Quick 包括多个包含额外类型的子模块。
There are a number of basic types that are supported by default in the QML language .
此外，
QtQuick
import provides the following basic types:
| color | ARGB color value. The color type refers to an ARGB color value. It can be specified in a number of ways: |
| font | Font value with the properties of QFont. The font type refers to a font value with the properties of QFont |
| matrix4x4 | A matrix4x4 type is a 4-row and 4-column matrix |
| quaternion | A quaternion type has scalar, x, y, and z attributes |
| vector2d | A vector2d type has x and y attributes |
| vector3d | Value with x, y, and z attributes |
| vector4d | A vector4d type has x, y, z and w attributes |
Most object types provided by the
QtQuick
import are based on the
Item
type, which itself derives from
QtObject
.
QML 对象类型
provided by the Qt QML module (such as
QtObject
and
组件
) are also available when you import
QtQuick
