MATLAB: Listbox grep for a GUI

callbacklistbox

I have a GUI that I created using uicontrols and part of my GUI is a listbox that contains all of the names of calibration blocks of a model the user chooses. I want to add an edit box beneath the listbox so when a user starts typing the name of a cal all of the cals that don't match what the user is typing disappear. Basically is there a way for the edit box to run a callback function everytime a keystroke is entered?

MATLAB: GUI listbox

strings = get(hObject, 'string');
curval = get(hObject, 'value');
if iscell(strings)
  curstring = strings{curval};
else
  curstring = strings(curval, :);  %char array
end

Whether the string parameter is a cell array of strings, or a char array, depends on exactly how the listbox was initialized. If it was initialized to a single string that did not have any '|' characters, or initialized to a char array, then a char array will be the result, but if it was initialized to a cell array of strings, or to a single string that had on or more '|' characters, then a cell array will be the result.

MATLAB: Inserting data to listbox

Try this in the callback function of the pushbutton:

listboxItems = handles.popupmenu1.String; % Get existing list from the popup
listboxItems{end+1} = handles.edit10.String; % Append edit field 10.
% Put new list back in the popup:
handles.popupmenu1.String = listboxItems;

You can sort it if you want with sort().
