在Halcon中使用Qt5实现可交互的矩形、圆形和多边形ROI区域的ListView列表视图功能

void FormScalingTest::drawSelectedRegion(HRegion *_region)
{
	HTuple Row1, Row2, Column1, Column2, Radius1;
	HRegion hv_Region;
	switch (m_selectedDrawType)
	{
	case 1:
		DrawRectangle1(m_windowHandle, &Row1, &Column1, &Row2, &Column2);
		GenRectangle1(&hv_Region, Row1, Column1, Row2, Column2);
		break;
	case 2:
		DrawCircle(m_windowHandle, &Row1, &Column1, &Radius1);
		GenCircle(&hv_Region, Row1, Column1, Radius1);
		break;
	case 3:
		DrawRegion(&hv_Region, m_windowHandle);
		break;
	default:
		break;
	}
	*_region = hv_Region;
}
