本实例主要用到了一下控件：指定点、指定矢量、面收集器、操作按钮、列表框
extern "C" DllExport void ufusr(char *param, int *retcod, int param_len){ try { theHoleCoordinates = new HoleCoordinates(); // The following method shows the dialog immediately theHoleCoordinates->Show(); } catch(exception& ex) { //---- Enter your exception handling code here ----- HoleCoordinates::theUI->NXMessageBox()->Show("Block Styler", NXOpen::NXMessageBox::DialogTypeError, ex.what()); } delete theHoleCoordinates;} HoleCoordinates::HoleCoordinates(){ try { // Initialize the NX Open C++ API environment HoleCoordinates::theSession = NXOpen::Session::GetSession(); HoleCoordinates::theUI = UI::GetUI(); theDialogName = "HoleCoordinates.dlx"; theDialog = HoleCoordinates::theUI->CreateDialog(theDialogName.c_str()); // Registration of callback functions theDialog->AddApplyHandler(make_callback(this, &HoleCoordinates::apply_cb)); theDialog->AddUpdateHandler(make_callback(this, &HoleCoordinates::update_cb)); theDialog->AddInitializeHandler(make_callback(this, &HoleCoordinates::initialize_cb)); theDialog->AddDialogShownHandler(make_callback(this, &HoleCoordinates::dialogShown_cb)); } catch(exception& ex) { std::string exceptionText = ex.what(); throw; }}构造函数里，我们需要关注dlx文件加载，回调方法里面主要关注：提交方法apply_cb、更新方法update_cb、初始化方法initialize_cb。

axispoint = dynamic_cast<NXOpen::Point* >(pointCol[0]); 2、xDir、yDir 分别设置x和y的矢量方向，同时创建对应的基准轴 vectCol = xDirProperties->GetTaggedObjectVector("SelectedObjects"); refaxis1 = datumaxiscreater(axispoint, dynamic_cast<NXOpen::Direction* >(vectCol[0])); vectCol1 = yDirProperties->GetTaggedObjectVector("SelectedObjects"); refaxis2 = datumaxiscreater(axispoint, dynamic_cast<NXOpen::Direction* >(vectCol1[0])); 3、face 用来指定选着面 faceCol = faceProperties->GetTaggedObjectVector("SelectedObjects"); holeface = dynamic_cast<NXOpen::Face* >(faceCol[0]); 4、listBoxInfo 主要用来显示孔信息，并且在选着列表中的对象的时候，ug会激活选中状态 std::vector<NXOpen::NXString> str = listBoxInfoProperties->GetStrings("ListItems"); std::vector<int> index = listBoxInfoProperties->GetIntegerVector("SelectedItems"); 5、buttonInfo 用来获取孔的信息，并显示在listBoxInfo列表，获取孔信息的主要方法还是遍历特征，如下： NXOpen::Edge* seledge = selectedFaceEdges[ii]; NXOpen::Features::Feature* assocFeature = workPart->Features()->GetAssociatedFeature(seledge); std::string featureString = std::string(assocFeature->FeatureType().GetUTF8Text()); if (featureString.find("HOLE") != std::string::npos) { if (featureString.find("SIMPLE") != std::string::npos) { // Found NX5 type hole feature, add to NX 5 list allholesNX5.push_back(assocFeature->JournalIdentifier()); //allholesNX5.push_back(featureString); } else { // Found NX6 type hole feature, add to NX 6 list allholesNX6.push_back(assocFeature->JournalIdentifier()); //allholesNX6.push_back(featureString); } }
1、前端BlockUI使用控件：指定点、指定矢量、面收集器、操作按钮、列表框，主要知识点如下：
1）指定点、面收集器的使用及获取点坐标和面信息的方法
2）指定矢量的使用，初始化和获取选择的矢量方向
3）列表框的初始化和赋值方法
