I want a file to be opened in a new tab when I enter or double click it. I know there is t shortcut but I always open a file in a new tab and enter is more confortable for me.

Try adding

let NERDTreeMapOpenInTab='\r'

or

let NERDTreeMapOpenInTab='<ENTER>'

to your .vimrc.

This also causes enter on a directory to open in a new tab. – Valdis
how to traverse between file tabs in vim ? – Kerk
It doesn't work with gvim x32 with my windows 7 x64. Any idea? – Tough
There is this NerdTree + tabs plugin: github.com/jistr/vim-nerdtree-tabs could be useful. – Beauty
While this technically answers the question, it renders directories inaccessible. – Compost
@Valdis @Compost try this: let NERDTreeMapActivateNode='v' - you can use the v key to open/close directory nodes. – Dogcart

s will open the file currently under the cursor in a new vertically split window. Use t to open in a new tab.

Nice. This closes NERDTree window. Is there anyway to keep it open. – Glynisglynn
Found that 'T' opens in new tab – Glynisglynn

As described in section NERDTreeCustomOpenArgs of the NerdTree help, you can use this option to control the opening behavior of files and directories. Add the following statement to your .vimrc:

let NERDTreeCustomOpenArgs={'file':{'where': 't'}}

This ensures in this case that only files in a new tab are opened. All other combinations can be found in the help.

You may want to add https://github.com/Nopik/vim-nerdtree-direnter plugin as well - it fixes the directory opening problem, so enter on directory node will just expand/collapse, not open new tab.

I use following map to do tab traverse : 

nnoremap <C-l> gt
nnoremap <C-h> gT

Also, would this not conflict the default mapping of moving between split panes? Because I have tried doing exactly this. – Taipan

Add this to the plugin. It needs to be added to a file such as: ~/.vim/nerdtree_plugin/mymapping.vim. The exact location will depend on what plugin manager you use for vim. e.g. for Plugged it is ~/.vim/plugged/nerdtree/nerdtree_plugin/mymapping.vim

This code adds a mapping for the enter key to open files in a new tab while just expanding/collapsing directories. For the new tabs it also mirrors the NERDTree so it can be shared between tabs.

call NERDTreeAddKeyMap({
  \ 'key': '<CR>',
  \ 'scope': "Node",
  \ 'callback': 'OpenInNewTab',
  \ 'quickhelpText': 'open node' })


" FUNCTION: s:openInNewTab(target) {{{1
function! OpenInNewTab(node)
  if a:node.path.isDirectory
    call a:node.activate()
  else
    call a:node.activate({'where': 't'})
    call g:NERDTreeCreator.CreateMirror()
    wincmd l
  endif
endfunction

Will this be overwritten if I need to update the plugin? I assume it will if I delete then reinstall it. – Slat

For the double-click event specifically, it is (only?) possible by slightly changing the NERDtree source code (posted here):

Please, add the relevant information from your link into your answer. – Furtive
Changing the source code is a very bad idea, especially since NerdTree offers a lot of options for configuration. – Spermatogonium
