I have built a GUI using the GUI Editor and save the xml file.

By using loadGUI (), I can get the content of the xml file and the program will generate the corresponding GUI.

Now, I want to further edit the GUI using code.
For example, I built a menu bar in GUI editor, after loadGUI(), it will be shown. Now, I want to add submenus to it but I do not know how to refer to the menu (calling object) .

Could someone please help

why nobody helps -,-
Is there anything that I need to further explain?

maybe you can refer to this http://irrlicht.sourceforge.net/docu/example009.html

In tutorial 09, the config.xml loaded does not contain any GUI.
Also, that config.xml is different from the guiTest.xml generated by the GUI Editor.

So, I am afraid tutorial 09 cant help me

Now, I want to further edit the GUI using code.

Now, I want to add submenus to it

tutorial 9 shows you how to add sub-menu. you can give the main menu an id and later on search for the menu by referring to the id and then add sub-menus to it. i hope i understand your question correctly. is that what you want?

give an id to the menu, then find the gui element in your c++ code and edit it from there
