MATLAB: How I set a string in edit field when string is longer than the field itself

functionguimatlab gui

Hi guys,

I have an idea how I want it to behave but I have no clue how to do it. So I beg for help 🙂

I have edit field with for exaple max. 15 char…and I have char with for example 26 char and when i put it there I want to bw shown in edit field the end of the string and to sign that some of the text is missing I want there to be '…'

In example it will be better:

edit field 15char: xxxxxxxxxxxxxxx

string 26 char: abcdefgh…xyz

and when I put the sting in the field I want it to be shown like: …opqrstuvwxyz

Thanks for replies…Peter

I assume you refer to an uicontrol of style: edit, text or listbox.

Idea: store the full string in UserData and truncate before you set the property, String, of the uicontrol.

What about reading the inital number in the callback and appending a % afterwards. Then it does not matter if the user types "75" or "75%", or even "75 hello again, how are you?!":

uicontrol('Style', 'edit', 'String', '75 %', ...
          'Callback', @addPercentCB);
...
function addPercentCB(ObjectH, EventData)
str = get(ObjectH, 'String');
num = sscanf(str, '%g', 1);
if length(num) ~= 1
  warning('Bad number, using default instead');
  num = 75;
end
str = sprintf('%.0f %%', num);
set(ObjectH, 'String', str);

MATLAB: Set figure properties ‘String’

For uicontrol of style 'text', the String property is what is displayed in the uicontrol text area. For style 'edit', the String property is the text that is initially placed in the uicontrol edit area. For style 'radio' or 'push' or 'checkbox, the String property is the label to display. For 'list' or 'popup', the String property is the entries to put into the menus. In short, for uicontrol, the String property is something to display to the user.

For text() graphic objects, the String property is the text to be plotted.
