创建4个等大的视口：

1. void ZffCHAP4Create4VPorts()
2. {
3. // 获得视口表
4. AcDbViewportTable *pVPortTbl = NULL;
5. acdbHostApplicationServices()->workingDatabase()->getViewportTable(pVPortTbl, AcDb::kForWrite);
7. // 分别创建四个视口
8. AcGePoint2d pt1, pt2;
9. AcDbViewportTableRecord *pVPortTblRcd1=new AcDbViewportTableRecord;
10. pt1.set(0, 0);
11. pt2.set(0.5, 0.5);
12. pVPortTblRcd1->setLowerLeftCorner(pt1);
13. pVPortTblRcd1->setUpperRightCorner(pt2);
14. pVPortTblRcd1->setName("4VPorts");
16. AcDbViewportTableRecord *pVPortTblRcd2=new AcDbViewportTableRecord;
17. pt1.set(0.5, 0);
18. pt2.set(1, 0.5);
19. pVPortTblRcd2->setLowerLeftCorner(pt1);
20. pVPortTblRcd2->setUpperRightCorner(pt2);
21. pVPortTblRcd2->setName("4VPorts");
23. AcDbViewportTableRecord *pVPortTblRcd3=new AcDbViewportTableRecord;
24. pt1.set(0, 0.5);
25. pt2.set(0.5, 1);
26. pVPortTblRcd3->setLowerLeftCorner(pt1);
27. pVPortTblRcd3->setUpperRightCorner(pt2);
28. pVPortTblRcd3->setName("4VPorts");
30. AcDbViewportTableRecord *pVPortTblRcd4=new AcDbViewportTableRecord;
31. pt1.set(0.5, 0.5);
32. pt2.set(1, 1);
33. pVPortTblRcd4->setLowerLeftCorner(pt1);
34. pVPortTblRcd4->setUpperRightCorner(pt2);
35. pVPortTblRcd4->setName("4VPorts");
37. pVPortTbl->add(pVPortTblRcd1);
38. pVPortTbl->add(pVPortTblRcd2);
39. pVPortTbl->add(pVPortTblRcd3);
40. pVPortTbl->add(pVPortTblRcd4);
41. pVPortTbl->close();
42. pVPortTblRcd1->close();
43. pVPortTblRcd2->close();
44. pVPortTblRcd3->close();
45. pVPortTblRcd4->close();
47. struct resbuf rb;
48. acedGetVar("TILEMODE", &rb);
49. if (rb.resval.rint == 1)  // 当前工作空间是模型空间
50. {
51. acedCommand(RTSTR, ".-VPORTS", RTSTR, "R",RTSTR, "4VPorts", RTNONE);
52. }
53. else // 当前工作空间是图纸空间
54. {
55. acedCommand(RTSTR, ".-VPORTS", RTSTR, "R",RTSTR, "4VPorts", RTSTR, "", RTNONE);
56. }
57. }

图纸空间创建一个新的视口：

1. void ZffCHAP4CreateVPortInSpace()
2. {
3. // 指定当前布局
4. Acad::ErrorStatus es = acdbHostApplicationServices()->layoutManager()->setCurrentLayout("布局1");
5. if (es != Acad::eOk)
6. {
7. return;
8. }
10. // 获得块表
11. AcDbBlockTable *pBlkTbl = NULL;
12. acdbHostApplicationServices()->workingDatabase()->getBlockTable(pBlkTbl, AcDb::kForRead);
14. // 获得图纸空间的块表记录
15. AcDbBlockTableRecord *pBlkTblRcd = NULL;
16. pBlkTbl->getAt(ACDB_PAPER_SPACE, pBlkTblRcd,AcDb::kForWrite);
17. pBlkTbl->close();
19. // 创建新的布局对象
20. AcDbViewport *pViewport = new AcDbViewport();
21. pViewport->setCenterPoint(AcGePoint3d(100, 50, 0));
22. pViewport->setHeight(80);
23. pViewport->setWidth(120);
25. // 将新的布局对象添加到图纸空间块表记录中
26. AcDbObjectId viewportId;
27. pBlkTblRcd->appendAcDbEntity(viewportId, pViewport);
28. pViewport->close();
29. pBlkTblRcd->close();
31. // 将新建的视口作为当前视口
32. AcDbViewport *pVP = NULL;
33. acdbOpenObject(pVP, viewportId, AcDb::kForWrite);
34. pViewport->setOn();//创建浮动视口之后，要想启用该视口，必须使用 setOn 函数
35. acedSetCurrentVPort(pVP);
36. pVP->close();
37. }
