## Detailed Description
该QPainterPath类提供一个容器,用于绘制操作,从而能够构造和重用的图形形状。
一个画家路径是大量的图形积木,如矩形,椭圆,直线和曲线组成的对象。积木可以在封闭的子路径被接合,例如为矩形或椭圆形。一个封闭的路径已重合的起点和终点。或者,他们可以独立存在的未封闭的子路径,如直线和曲线。
一个QPainterPath对象可用于填充,概述,和削波。要生成可填写概括为一个给定的画家路径,使用[QPainterPathStroker](qpainterpathstroker.html)类。画家路径超过正常的绘图操作的主要优点是,复杂的形状只需要创建一次,然后就可以使用绘制多次调用只对[QPainter.drawPath](qpainter.html#drawPath)()函数。
QPainterPath提供了可用于获得关于路径和它的元素的信息的功能的集合。此外,可以利用扭转元素的顺序的[toReversed](qpainterpath.html#toReversed)()函数。还有一些功能,这个画家路径对象转换为多边形表示。
### Composing a QPainterPath
甲QPainterPath对象可以被构造为一个空的路径,与给定的起始点,或者作为另一个QPainterPath对象的一个副本。一旦创建,直线和曲线可以使用被添加到路径的[lineTo](qpainterpath.html#lineTo)( )[arcTo](qpainterpath.html#arcTo)( )[cubicTo](qpainterpath.html#cubicTo)()和[quadTo](qpainterpath.html#quadTo)()函数。在直线和曲线舒展从[currentPosition](qpainterpath.html#currentPosition)()来作为参数传递的位置。
该[currentPosition](qpainterpath.html#currentPosition)该QPainterPath对象的( )始终是添加的最后一个子路径(或初始起点)的结束位置。使用[moveTo](qpainterpath.html#moveTo)( )函数来移动[currentPosition](qpainterpath.html#currentPosition)()无添加的成分。该[moveTo](qpainterpath.html#moveTo)()函数,隐启动一个新的子路径,并且关闭前一个。开始一个新的子路径的另一种方式是调用[closeSubpath](qpainterpath.html#closeSubpath)( )函数,它通过从添加一行关闭当前路径[currentPosition](qpainterpath.html#currentPosition)( )返回路径的起始位置。请注意,新的路径不会有(0,0 ),作为其初始[currentPosition](qpainterpath.html#currentPosition)( ) 。
QPainterPath类还提供了一些方便的功能来封闭的子路径添加到一个画家路径:[addEllipse](qpainterpath.html#addEllipse)( )[addPath](qpainterpath.html#addPath)( )[addRect](qpainterpath.html#addRect)( )[addRegion](qpainterpath.html#addRegion)()和[addText](qpainterpath.html#addText)( ) 。该[addPolygon](qpainterpath.html#addPolygon)( )函数添加_unclosed_子路径。事实上,这些功能是所有集合[moveTo](qpainterpath.html#moveTo)( )[lineTo](qpainterpath.html#lineTo)()和[cubicTo](qpainterpath.html#cubicTo)( )操作。
此外,一个路径可以使用被添加到当前路径[connectPath](qpainterpath.html#connectPath)()函数。但要注意,这个函数将在当前路径的最后一个元素连接到给定的一个的第一个元素添加一行。
下面是一个代码片段显示了如何QPainterPath对象可用于:
| ![](https://img.kancloud.cn/e7/b5/e7b5ebcb666bcea64725d2796a8fac5a_100x100.png) |
```
QPainterPath path;
path.addRect(20, 20, 60, 60);
path.moveTo(0, 0);
path.cubicTo(99, 0, 50, 50, 99, 99);
path.cubicTo(0, 99, 50, 50, 0, 0);
[QPainter](qpainter.html) painter(this);
painter.fillRect(0, 0, 100, 100, [Qt](qt.html).white);
painter.setPen([QPen](qpen.html)([QColor](qcolor.html)(79, 106, 25), 1, [Qt](qt.html).SolidLine,
[Qt](qt.html).FlatCap, [Qt](qt.html).MiterJoin));
painter.setBrush([QColor](qcolor.html)(122, 163, 39));
painter.drawPath(path);
```
|
当构建画家路径最初是空的。我们首先添加一个矩形,这是一个封闭的子路径。然后,我们添加两个贝兹曲线共同构成,即使他们不是单独关闭一个封闭的子路径。最后,我们绘制整个路径。该路径是使用默认的填充规则填充,[Qt.OddEvenFill](qt.html#FillRule-enum)。 Qt提供了两种方法来填充路径:
| [Qt.OddEvenFill](qt.html#FillRule-enum) | [Qt.WindingFill](qt.html#FillRule-enum) |
| --- | --- |
| ![](https://img.kancloud.cn/cb/54/cb54e06e32ea25c12fdba39c319de1af_230x204.png) | ![](https://img.kancloud.cn/ad/c7/adc72ed5173ee823e438445a2756f050_231x202.png) |
请参阅[Qt.FillRule](qt.html#FillRule-enum)文档规则的定义。一个画家路径的当前设置填充规则可使用检索到的[fillRule](qpainterpath.html#fillRule)()函数,并使用改变了[setFillRule](qpainterpath.html#setFillRule)()函数。
### QPainterPath Information
该QPainterPath类提供的功能的集合,它返回的路径及其元素的信息。
该[currentPosition](qpainterpath.html#currentPosition)( )函数返回已添加的最后一个子路径(或初始起点)的终点。该[elementAt](qpainterpath.html#elementAt)()函数可以被用于检索各个子路径元素,则_number_元素可使用检索到的[elementCount](qpainterpath.html#elementCount)()函数,并且[isEmpty](qpainterpath.html#isEmpty)( )函数告诉这个QPainterPath对象是否包含在所有的任何元素。
该[controlPointRect](qpainterpath.html#controlPointRect)( )函数返回一个包含此路径的所有点和控制点的矩形。这个功能是显着更快的计算比精确[boundingRect](qpainterpath.html#boundingRect)( )返回这个画家路径的边界矩形与浮点精度。
最后, QPainterPath提供[contains](qpainterpath.html#contains)()函数可以被用来确定一个给定的点或矩形是否是路径内,并且[intersects](qpainterpath.html#intersects)( )函数,它确定是否任何一个给定的矩形内的点也都是这个路径里。
### QPainterPath Conversion
由于兼容性的原因,它可能需要简化画家路径的表示: QPainterPath提供[toFillPolygon](qpainterpath.html#toFillPolygon)( )[toFillPolygons](qpainterpath.html#toFillPolygons)()和[toSubpathPolygons](qpainterpath.html#toSubpathPolygons)( )函数的转换画家路径转换为多边形。该[toFillPolygon](qpainterpath.html#toFillPolygon)( )返回画家路径作为一个单独的多边形,而后面两个函数返回的多边形列表。
该[toFillPolygons](qpainterpath.html#toFillPolygons)()和[toSubpathPolygons](qpainterpath.html#toSubpathPolygons)提供()函数,因为它通常是更快地绘制几个小的多边形,而不是绘制一个大的多边形,即使点绘制的总数是相同的。两者之间的区别是_number_多边形他们返回:该[toSubpathPolygons](qpainterpath.html#toSubpathPolygons)( )创建一个多边形的每个子路径,无论相交的子路径(即重叠边界矩形) ,而[toFillPolygons](qpainterpath.html#toFillPolygons)( )函数只创建一个重叠的子路径多边形。
该[toFillPolygon](qpainterpath.html#toFillPolygon)()和[toFillPolygons](qpainterpath.html#toFillPolygons)( )函数首先将所有的子路径为多边形,然后使用倒带技术,以确保重叠的子路径可以使用正确的填充规则来填补。注意,倒带插入附加行中的多边形,以便填充多边形的轮廓并不路径的轮廓相匹配。
### Examples
Qt提供了[Painter Paths Example](index.htm)和[Vector Deformation Demo](index.htm)分别位于Qt的例子和演示目录分别。
该[Painter Paths Example](index.htm)显示了画家的路径如何可以用来构建复杂的形状进行渲染,并让用户实验用的填充和描边。该[Vector Deformation Demo](index.htm)展示了如何使用QPainterPath绘制文本。
