7.5 表格

BIMBase API可直接创建表格，相关对象包括BPTableEntity、BPTableCellEntity、BPTableEntityManager，常用接口见下表。

示例代码7-8创建了一个当前工程中Cube对象的列表。首先获取当前工程所有Cube对象，创建表格，在表格中展示每个Cube对象的长、宽、高信息。

//获取当前工程所有立方体
vector<DemoObject::CubeDemo> vctCube;
BPProjectP pProject = BPApplication::getInstance().getProjectManager()->getMainProject();
if (pProject == nullptr)
    return;
BPEntityArray entityArray;
BPEntityUtil::getEntities(entityArray, *pProject, PBM_SCHEMA_Demo, PBM_CLASS_CUBE_Demo);
if (entityArray.getCount() == 0)
    return;

for (int i = 0; i < entityArray.getCount(); i++)
{
    BPEntityPtr curr = entityArray.getByIndex(i);
    if (!curr || !curr.isValid())
        continue;

    BIMBase::Core::BPDataPtr ptrData = BPDataUtil::getDataOnEntity(*curr);
    if (!ptrData.isValid())
        continue;
    //根据根据实例初始化
    CubeDemo pbCube;
    pbCube.initFromData(*ptrData);
    vctCube.push_back(pbCube);
}
if (vctCube.size() == 0)
{
    AfxMessageBox(_T("请先布置立方体"));
        return;
}


if (pProject == nullptr)
    return;
//创建表格
BPTableEntityP table = new BPTableEntity;
table->setRowNum(vctCube.size() + 2);
table->setColumnNum(4);
table->setColWidths(10000);
table->setRowHeight(2000);
table->addCellForTable();

BPModelBaseP pModel = pProject->getActiveModel();
if (pModel == nullptr)
    return;
BPTableEntityManager tablemanager = BPTableEntityManager(table);

table->setTransform(p3d::GeTransform::create(0, 20000, 0));
p3d::P3DStatus status = table->addToProject(*pProject, pModel->GetModelId());

auto fun = [&](PString sCur,bool bUnderlinedCur,bool bBold, UInt32 colorCur, double HangingIndentCur, int cellR,int cellC)
{
    //创建一个文字
    BPMTextEntity pbmtext;
    BPFont font1 = BIMBase::Core::BPFontUtil::getDefaultTrueTypeFont();
    //多行文字之间的段落设置
    MTextParagraphPropertiesAppenderPtr ptrAppender = new MTextParagraphPropertiesAppender;
    ptrAppender->isFullJustified = false;
    ptrAppender->mtext_FirstLineIndent = 0;
    ptrAppender->mtext_HangingIndent = HangingIndentCur;
    pbmtext.appendTextPart(ptrAppender);

    ptrRunAppender->color = colorCur;
    ptrRunAppender->isBold = bBold;
    ptrRunAppender->isItalic = false;
    ptrRunAppender->isUnderlined = bUnderlinedCur;
    ptrRunAppender->isOverlined = false;
    ptrRunAppender->font = font1;
    ptrRunAppender->overrideFontSize = true;
    ptrRunAppender->fontSize = GePoint2d::create(400, 600);
    pbmtext.appendTextPart(ptrRunAppender);
    //多行文字内容设置
    MTextTextLineAppenderPtr ptrTextAppender = new MTextTextLineAppender;
    ptrTextAppender->mtextLine = sCur;
    pbmtext.appendTextPart(ptrTextAppender);
    tablemanager.setContextEntityForCell(&pbmtext, cellR, cellC);
