    Hello.
    Is it possible to populate the strings in a popup menu from
    an ini (text file).

    The number of items will increas eovertime and rather than
    going into the code, it would be really useful to have some
    config file.

  2. A .m file is just an ini file with an unusual name
    and a very flexible initialization syntax. But you do
    not have to use the full power of the initialization syntax;
    you could, for example, have

    set(m17_file_SaveAs_handle,'String','Save As')

    Or you could have in your ini file

    m17_file_SaveAs_string = 'Save As';

    and then in your code after you had processed the ini file you
    could have

    set(m17_file_SaveAs_handle,'String',m17_file_SaveAs_string);


    If these were perhaps not what you had in mind, it might
    help to be more specific about the format you were thinking of.

    Hi,
    I was thinking more along the lines of having a text file
    with a list of items that I can add to (in my case
    fluorescence filters)

    e.g.

    sm580_15
    sm590_35
    sm610_45
    sm650_20

    etc.

    and then from the text file, when I run my matlab program,
    it automatically populates the popup menu. (At some stage I
    will want to compile it to an EXE and then have the users
    able to just change a text file to add more filters).

    I guess I would have to tell the popupmenu how many items
    where in the list?

  4. You can use textscan() or any of several other I/O routines
    to read the contents of the file. Once you have the file read
    into a cell string, set() the 'String' property of the popup
    to be that cell string. You will not need to tell the popup
    menu how many items were in the list: it will count them automatically.
