dhtmlxTree and contextMenu question

Hi, I use dhtmlxTree with contextMenu and works fine :-)

But I have a question:
Is posible to get a context menu checked option depending of userData value of the xTree node?

Now I change a userData with the contextMenu but I want to view the selected userData in this menú.

It's possible?

Thanks for all

Kind Regards

You can attach custom code to onShow event of menu and update menu dynamically based on current node ( or its userdata )

aMenu.setOnShowMenuHandler(function(id){
    //id of item for which menu will be opened
    aMenu.menu.getItem("some").setText(tree.getUsedData(id,"some"));
});

Is possible to set a img src?

Now I have this function

       objAMenu.setOnShowMenuHandler(function(treeitemId){
               if(opcio = punterTreeAssoc['objA'].getUserData(treeitemId,'simple_acl'))
               {
                   objAMenu.menu.getItem(opcio).setText('* ' + opcio);                           
               }
            });


To reset the old setText actions I need to re-process all menu items?

well I supose that I make a lot of work-arrounds to get the 'Selected item' menu functionality  :-)

>>Is possible to set a img src?
There is no API, but can be done as
     aMenu.menu.getItem("some").imageTag.src="new url";

Actually to make menu specific for selected item - it is a too complex approach.

You can create a set of necessary items in menu, and just use
    menu.showButtons
    menu.hideButtons
to make it actual for currently selected item.
