如何在AutoCAD中加载自己的工具条

JA_JERRY 发表于 2005-1-17 17:39:00

我在编程序时，要用到很多的非模态对话框，可是一不小心关掉就再也出不来了，因此我想在用AutoCAD加载程序时也加载一个工具条，只要点击一下工具条就可以出现我所需要的对话框，可是我编的程序编译，链接都可以，就是在AutoCAD中看不到我要的工具条，下面是我的做法，希望高手指点:

1、用ARX向导建立一个USE MFC的程序框架。

2、在资源中创建一个工具条，ID为IDR_TOOLBAR_DEMO；

3、用“ObjectARX定义命令”对话框注册命令，在Internation栏填入CreateToolBar，然后点击编辑代码，并在XXXCommands.cpp中顶端加入#include"resource.h"

代码如下：

void jerryCreateToolBar() { if(!m_MyToolBar.CreateEx(NULL,TBSTYLE_FLAT,WS_CHILD|WS_VISIBLE|CBRS_TOP|CBRS_GRIPPER|CBRS_TOOLTIPS |CBRS_FLYBY|CBRS_SIZE_DYNAMIC)||!m_MyToolBar.LoadToolBar(IDR_TOOLBAR_DEMO)) { TRACE0("Failed to create toolbar\n"); return ; } m_MyToolBar.EnableDocking(CBRS_ALIGN_ANY); }

请问各位高手，我错在了哪里？我的功能应该如何实现？

仔细看一下,稍微改一点你就可以用了.这些就在arx自带的帮助里!这要比你自己写好的多,我试过,直接拷过来就可以用!而且步骤也很清楚.

This method accesses AutoCAD ActiveX Automation through pure COM techniques. This method requires more coding, but does not rely on MFC. The sample program uses the COM ActiveX Automation interfaces to add a new shortcut menu to the AutoCAD menu bar. The following procedures demonstrate the necessary steps:

The next step is to decide which interfaces are necessary to access the AutoCAD menu bar. In this case, IAcadApplication, IAcadMenuBar, IAcadMenuGroups, IAcadMenuGroup, IAcadPopupMenus, IAcadPopupMenu, and IAcadPopupMenuItem are required. To get the definitions of these interfaces, use the AutoCAD type library (acad.tlb) as shown in the next procedure.

Now that your application imports the proper interfaces, you can use them to implement AutoCAD functionality. The more direct COM approach to Automation uses QueryInterface to access the IUnknown of AutoCAD and its Automation components. The next procedure shows how to accomplish this. All code examples in this procedure should be added to your addMenuThroughCOM() function in the sequence presented.

Both of these examples can be found in the ObjectARX SDK. They are located in the docsamps\comsamps directory. Each sample contains code for adding a circle and a menu using either Win32 API or MFC programming techniques. Because these methods access AutoCAD through COM interfaces, these programming techniques can be used from other C++ contexts--not just from ObjectARX. Similar techniques can also be used in other languages, such as Visual Basic.
