无法隐藏模式对话框
<P>用以下代码创建了一个模式对话框：</P><P><STRONG>CAcModuleResourceOverride resOveride;<BR>CModalDlg pDlg(CWnd::FromHandle(adsw_acadMainWnd()));<BR>pDlg.DoModal();</STRONG></P>
<P>点对话框中一个按钮，添加如下代码，希望隐藏对话框：</P>
<P><STRONG>ShowWindow(SW_HIDE);</STRONG></P>
<P>对话框是隐藏了，但焦点回不了acad的主界面了，就是鼠标点不了acad的界面，包括菜单、绘图区等等，没有任何错误提示，程序也没有“无响应”。</P>
<P>请问大家，这是怎么回事？</P>

你可以使用CAcUiPickButton,在事件处理中用<BR> BeginEditorCommand();<BR> CancelEditorCommand();<BR>参见..\arx_sdk\ObjectARX2004\samples\editor\mfcsamps\acuisample_dg例子 是的.grass说的有道理。 <P>谢谢<A name=55883><FONT color=#990000><B>王咣生</B></FONT></A>斑竹！</P> <P>现在点击了模式对话框的按钮，生成一条直线，只有退出模式对话框才能显示该直线，请问要如何才能更新绘图区呢？</P> <P>更新绘图区acedGetAcadDwgView()->UpdateWindow();</P><P> </P> yfy2003发表于2005-9-10 10:19:00static/image/common/back.gif
更新绘图区acedGetAcadDwgView()->UpdateWindow();
