demo uistyler position selection

lirui0726

To test this example - you must create a simple dialog:
    1.  Change CHANGE to test
    2.  Assign the constructor "const_cb" on the Callbacks tab
    3.  Enable selection on the Selection tab
    4.  Enable both Single Postion and Rectangle Position
    5.  Save the dialog to your application directory as test.dlg

程序实验过了，谢谢版主，今天看了版主推荐的书，突然感觉自己的思路有点儿错误，如果想实现交互功能，完全可以应用UG提供的标准对话框函数，准备试一下uc1609（），应该能满足要求！

何不试试uc1613,功能更全

恩，对，可以输入多种数据！
