Hi Elisabeth, If you're still using tkgui.addMenu, that returns a Tkinter.Menu instance. You add an item to the menu with: menu.add_command(label="menu item name", command=myFunc) which will cause myFunc to get called (with no arguments) when that menu item is selected. There's a lot of documentation available for the Tkinter.Menu class, just Google "Tkinter menu". I personally use: http://infohost.nmt.edu/tcc/help/pubs/tkinter/ but that may or may not be overkill for your purposes. Also, Chimera's tkgui._createMenus function shows a lot of uses of Tkinter.Menu instances. --Eric Eric Pettersen UCSF Computer Graphics Lab http://www.cgl.ucsf.edu On Jan 24, 2011, at 10:40 AM, Elisabeth Ortega wrote:
Dear Chimera Dev Team,
I created a new item in the menu bar but my question now is how can I put options in the new bar? As you know, to put any option in the menu 'Tools' we "only" have to copy the new folder in chimera/ share/ . I'm trying to do the same with my new item but the only way that I found to do so is modifying the ChimeraExtension.py file of VolumeMenu. Exists any other possibility much easier than that?
