char *cue="调用点构造器”;
UF_UI_POINT_base_method_t base_method;
tag_t point_tag;
double base_pt[3];
int *response;
int status;
status = UF_UI_point_construct(cue, [$base_method, &point_tag, base_pt, response)]
if(status == 0)
{
UF_UI_open_listing_window();
UF_UI_write_listing_window("successfully run the function!");
}
if(status != 0)
{
UF_UI_open_listing_window();
UF_UI_write_listing_window("Failed to run the function!");
}
编译运行后系统显示“Failed to run the function!也就是说status返回的值非0，但是不知程序哪个地方出问题了，还请高手指点。
使用uc1616()调用的代码：
char *cp1="point construct";
int *ia2=0;
int ip3,status;
double rr4[3];
status = uc1616(cp1, ia2, ip3, rr4);
if(status == 0)
{
UF_UI_open_listing_window();
UF_UI_write_listing_window("successfully run the function!");
}
if(status != 0)
{
UF_UI_open_listing_window();
UF_UI_write_listing_window("Failed to run the function!");
}
运行结果同上，也不知哪出了问题。作者: 深夜摔键盘 时间: 2005-5-22 01:19
base_method没赋初值。作者: orangecard 时间: 2005-5-22 13:03
一定要赋初值么，我想通过用户自选取点方式来选取点，如果赋了初值岂不是只能用一种选点的方法了？作者: 深夜摔键盘 时间: 2005-5-22 13:05
点构造器实际上是一个对话框面板，上面有许多工具，你赋的初值是作为默认值来对待的。作者: orangecard 时间: 2005-5-22 16:58
键盘哥:程序已经调通，万分感谢。还有一点，在调入点构造器后发现X,Y,Z坐标输入框中的值都为-92559631349317831.0000虽然没什么大的影响但总是看着不爽，不知键盘兄能否指点一二将这些值全调为0？再次感谢！！！！作者: 深夜摔键盘 时间: 2005-5-22 21:10
试试把double base_pt[3] 赋上初值看一看。
另外点构造器最后一个参数，不要给它指针，可以取局部变量的地址来做参数。要给指针也可以，但必须在API之外为这个指针分配内存，还要记着释放，因为API不会为你的指针分配空间的。虽然这个程序能运行，但是存在隐患。作者: dasanlang 时间: 2005-5-24 13:35

以上是我查找到的UF_UI_point_construct,以及uc1616的函数原型,我想问这个UF_UI_point_construct中创建smart point是个什么含义?作者: nihai0711501129 时间: 2011-11-17 09:29
上面的代码怎么看不见啊
谢了！
