touchGFX中如何绘制多边形

[arno-1104]

做控制界面的时候用了TouchGFX，目前需要绘制一个颜色可变的三角形，并且位置可以移动，目前的想法是用shape类绘制，但是shape怎么使用？

Shape<3> shape;
PainterRGB888 shapePainter;
shape.setCorner(0, CWRUtil::Q5(25), CWRUtil::Q5(0));
shape.setCorner(1, CWRUtil::Q5(0), CWRUtil::Q5(50));
shape.setCorner(2, CWRUtil::Q5(50), CWRUtil::Q5(50));
//shape.setShape();
shapePainter.setColor(touchgfx::Color::getColorFrom24BitRGB(18, 141, 172));
shape.setPainter(shapePainter);
shape.setPosition(0,0,100,100);
 //shape.setXY(0,0);
shape.setWidth(0);
shape.setAlpha(0xaa);
shape.setVisible(true);
//shape.setHeight(100);
shape.setOrigin(25,0);
        
add(shape);

不知道问题出在了哪里？各路大神为指点迷津
