## Detailed Description
这个类可以醃制。
该QLineF类提供了使用浮点精度二维向量。
甲QLineF描述了一个二维表面上的有限长度线（或线段） 。 QLineF定义了使用浮点精度坐标的线的起点和终点。使用[toLine](qlinef.html#toLine)（ ）函数来检索此行的一个基于整数副本。
|  |  |
可使用检索到的线的开始点和结束点的位置的[p1](qlinef.html#p1)（ ）[x1](qlinef.html#x1)（ ）[y1](qlinef.html#y1)（ ）[p2](qlinef.html#p2)（ ）[x2](qlinef.html#x2)（）和[y2](qlinef.html#y2)（）函数。该[dx](qlinef.html#dx)（）和[dy](qlinef.html#dy)（）函数返回该行的水平和垂直分量。
该生产线的长度可以通过检索的[length](qlinef.html#length)（）函数，并使用改变了[setLength](qlinef.html#setLength)（）函数。同样，[angle](qlinef.html#angle)（）和[setAngle](qlinef.html#setAngle)（）分别用于检索和改变线的角度。使用[isNull](qlinef.html#isNull)（ ）函数来确定QLineF是否代表一个有效的行或空行。
该[intersect](qlinef.html#intersect)（ ）函数确定[IntersectType](qlinef.html#IntersectType-enum)对于这条线和一个给定的线，而[angle](qlinef.html#angle)（ ）函数返回线之间的夹角。此外，该[unitVector](qlinef.html#unitVector)（）函数返回具有相同的起始点作为该行的线，但是仅为1的长度，而[normalVector](qlinef.html#normalVector)（ ）函数返回一个线垂直于这条线具有相同的起点和长度。
最后，该线可以被转换的给定使用偏移[translate](qlinef.html#translate)（）函数，并且可以使用被遍历的[pointAt](qlinef.html#pointAt)（）函数。

## Type Documentation
```
QLineF.IntersectType
```
描述两条线之间的交点。
|  |  |
| QLineF.UnboundedIntersection | QLineF.BoundedIntersection |
| Constant | Value | Description |
| --- | --- | --- |
| `QLineF.NoIntersection` | `0` | 表明该线没有相交，也就是说，它们是平行的。 |
| `QLineF.UnboundedIntersection` | `2` | 这两条线相交，但不被它们的长度所定义的范围之内。这将是这种情况，如果线不平行。 |
[intersect](qlinef.html#intersect)（）也将返回该值，如果相交点是唯一的线路之一的开始和结束点内。
| Constant | Value | Description |
| --- | --- | --- |
| `QLineF.BoundedIntersection` | `1` | 两条线彼此相交的每一行的开始和结束点内。 |
