对nsITreeView.idl 接口文件修改的影响

hechengjin

1. 手动增加
   
2. \nsITreeView.idl
   
3. interface nsITreeView : nsISupports
   
4. {
   
5.   long getRowFlags(in long rowIndex);
   
6. }
   
7. 动态生成
   
8. nsITreeView.h
   
9.   /* long getRowFlags (in long rowIndex); /
   
10.   NS_IMETHOD GetRowFlags(int32_t rowIndex, int32_t *_retval) = 0;
    
11.   NS_IMETHOD GetRowFlags(int32_t rowIndex, int32_t *_retval); \
    
12.   NS_IMETHOD GetRowFlags(int32_t rowIndex, int32_t *_retval) { return _to GetRowFlags(rowIndex, retval); } \
    
13.   NS_IMETHOD GetRowFlags(int32_t rowIndex, int32_t *_retval) { return !to ? NS_ERRORNULLPOINTER : _to→GetRowFlags(rowIndex, _retval); } \
    
14. / long getRowFlags (in long rowIndex); */
    
15. NS_IMETHODIMP nsTreeView::GetRowFlags(int32_t rowIndex, int32_t *_retval)
    
16. {
    
17.     return NS_ERROR_NOT_IMPLEMENTED;
    
18. }
    
19. 
    
20. 
    
21. 根据上面动态生成的内容可以手动在下面相关文件中加入对应的函数实现，注意区分大小写
    
22. nsMsgDBView.cpp
    
23. NS_IMETHODIMP nsMsgDBView::GetRowFlags(int32_t rowIndex, int32_t *_retval)

79.         return NS_OK;
    
80. }

//下面这个看情况是否要加入
nsMsgGroupView.cpp
NS_IMETHODIMP nsMsgGroupView::GetRowFlags(int32_t rowIndex, int32_t *_retval)
{
        NS_ENSURE_ARG(aResult);
        if (!IsValidIndex(aIndex))
                return NS_MSG_INVALID_DBVIEW_INDEX;


*aResult = m_flags[aIndex];
        return NS_OK;
}
nsMsgGroupView.h
NS_IMETHOD GetRowFlags(int32_t rowIndex, int32_t *_retval);

还要在  folderPane.js
左侧树邮件夹中实现对应接口

1. 
   
2. /**
   
3. * This is our controller for the folder-tree. It includes our nsITreeView
   
4. * implementation, as well as other control functions.
   
5. */
   
6. let gFolderTreeView = {
   
7. ...
   
8. // ****************** Start of nsITreeView implementation **************** //
   
9. ...
   
10. isShowMoreLeftOnServer: function ftv_isShowMoreLeftOnServer(aIndex) {
    
11.     return false;
    
12.   },
    
13.   ifShowMoreLeftOnServerRow: function ftv_ifShowMoreLeftOnServerRow(aIndex) {
    
14.     return false;
    
15.   },
    
16. 
    
17.   getMsgNumLeftOnServer: function ftv_getMsgNumLeftOnServer(aRow) {
    
18.     return "";
    
19.   },
