[求助]无模式对话框如何获得光标?
<p>在arx中建立无模式对话框，运行后，需要先在autocad中进行选择等操作，再回到无模式对话框中进行输入操作，但无模式对话框无法获得光标，我知道有一个keepfocus函数，但无论是返回true还是false，都无法实现光标在autocad和无模式对话框中自由切换。这个问题该如何解决?有哪位能指点一下，非常感谢1</p> <p>看文档，</p><p>在你使用acedXXXXX的时候：</p><p>1.你的类必须继承于CAdUiXXXX</p><p>2.在使用acedXXXXX之前调用BeginEditorCommand()</p><p>3.在之后根据成功失败的情况调用CompleteEditorCommand()或CancelEditorCommand();</p><p>文档中有下面的论述：</p><ol><li class="list_1" value="4">Add the button handlers for picking a point and angle using the AutoCAD editor.
