MATLAB: Matlab Listbox GUI No Selection

Question

I asked previously about setting the listbox properties so that when a list of files is loaded, the first one is not selected. I was told there was no way around that, which basically concluded as well. However, after chance, I determined that if I clicked in the empty box, then loaded the file names in the box, none of them would be selected. Is there anyway to "fake" a mouse click? It only happens if I click, or double click inside the listbox. I was trying something along the lines of:

set(handles.figure1,'SelectionType','open')

I tried that inside of (files is the listbox tag-this function executes on selection change in filebox:

function files_Callback(hObject, eventdata, handles)

Any hope with this?

Answer 1

I have trouble understanding your question. Isn't there one negation too many? However,

• regarding "fake mouse click" read about awt.robot at http://undocumentedmatlab.com/blog/gui-automation-robot/. IMO not worth the trouble.
• regarding "none selected" with code

    set( listbox_handle, 'Value', [] )

• regarding "none selected" interactively I've failed an added the string "- none -" at the top of the list. Selecting that row triggers

    set( listbox_handle, 'Value', [] )
