MATLAB: How to make a listbox that enters values into an edit box

MATLAB

I want to create a GUI in which a listbox controls the values put into an edit box.

Best Answer

The following example creates 2 uicontrols. One is a listbox, the other is an editable text box. The callBack from the listBox stores the listbox's String (s) and the listbox's value(v). The string is set by indexing into s with v.
function exampleGUI
      editUI = uicontrol('Style','edit','tag','editbox');
      listbox = uicontrol('style','listbox','units','normalized',...
          'Position',[.1 .1 .4 .4],'String',{'a';'b';'c';'d'});
      % Define listbox Callback property to update edit box
      set(listbox, 'Callback', @(src, evt) listCallback(src, editUI));
end
function listCallback(src, editBoxHandle)
      % Get current selection number
      value = get(src, 'Value');
      % Get entire string array.
      strArr = get(src,'String');
      % Index into string array to retrieve selection
      selection = strArr{value};
      set(editBoxHandle, 'String', selection);
end
