OBJECT ARX 循环创建多线段（提示用户选择线宽，颜色，点）

admin

1. //创建多段线==================
4. static ads采用real GetWidth(){
5. ads采用real width = 0;
6. if(acedGetReal(采用T("\n输入线宽"),&width) == RTNORM){
7. return width;
8. }
9. else{
10. return 0;
11. }
14. }
16. static int GetColorIndex(){
17. int colorIndex = 0;
18. if(acedSetColorDialog(colorIndex,Adesk::kFalse,256) != IDOK){
19. return 0;
20. }
21. else{
22. return colorIndex;
23. }
24. }
27. 添加多段线，用户指定点、线宽、颜色
28. static void TESTaddplcmd(){
29. int colorIndex = 255;
30. ads采用real width = 1;
33. int index = 2;
34. ads采用point ptStart;
37. //提示用户输入起始点
38. if(acedGetPoint(NULL,采用T("\n输入第一点"),ptStart) != RTNORM){
40. return;
41. }
43. ads采用point ptPrevious,ptCurrent;//前一个参考点，当前拾取的点
44. acdbPointSet(ptStart,ptPrevious);
45. AcDbObjectId polyId;//多段线的ID
48. 输入第二点
49. acedInitGet(NULL,采用T("W C O"));
50. int rc = acedGetPoint(ptPrevious,采用T("\n输入下一点[宽度(W)颜色(C)]<完成(O)>:"),ptCurrent);
51. while(rc == RTNORM || rc == RTKWORD){
53. if(rc == RTKWORD){如果用户输入了关键字
55. CString kword;
56. if(acedGetInput(kword.GetBuffer()) != RTNORM)
57. return;
58. if(kword.Compare(采用T("W")) == 0){
59. width = GetWidth();
60. }
61. else if (kword.Compare(采用T("C")) == 0){
62. colorIndex = GetColorIndex();
63. }
64. else if(kword.Compare(采用T("O")) == 0){
65. return;
66. }
67. else{
68. acutPrintf(采用T("\n无效的关键字"));
69. }
72. }
75. 如果用户输入了点
76. else if(rc == RTNORM){
77. if(index == 2){
78. 创建多线段
79. AcDbPolyline* pPoly = new AcDbPolyline(2);
81. AcGePoint2d ptGe1,ptGe2;//两个节点
82. ptGe1[X] = ptPrevious[X];
83. ptGe1[Y] = ptPrevious[Y];
84. ptGe2[X] = ptCurrent[X];
85. ptGe2[Y] = ptCurrent[Y];
86. pPoly->addVertexAt(0,ptGe1);
87. pPoly->addVertexAt(1,ptGe2);
90. 修改多线段的颜色和线宽
91. pPoly->setConstantWidth(width);
92. pPoly->setColorIndex(colorIndex);
95. 添加到模型
96. polyId = LoadEntity(pPoly);
97. pPoly->close();
98. }
101. else if(index > 2){
102. 修改多线段
103. AcDbPolyline* pPoly;
104. acdbOpenObject(pPoly,polyId,AcDb::kForWrite);
105. AcGePoint2d ptGe;//增加的节点
106. ptGe[X] = ptCurrent[X];
107. ptGe[Y] = ptCurrent[Y];
110. pPoly->addVertexAt(index - 1,ptGe);
111. 修改多线段的颜色和线宽
113. pPoly->setConstantWidth(width);
114. pPoly->setColorIndex(colorIndex);
117. //pPoly->setColorIndex(colorIndex);
118. pPoly->close();
119. }
120. index ++;
121. acdbPointSet(ptCurrent,ptPrevious);
122. }
123. acedInitGet(NULL,采用T("W C O"));
124. rc = acedGetPoint(ptPrevious,采用T("\输入下一点"),ptCurrent);
126. }
131. }
