how to change static text in MATLAB GUI?

First make up your string. Then set the 'String' property of the static text control to that string with the set() command. If it's in an intensive loop, you might have to use drawnow to get it to update immediately.

myString = sprintf('Hello world!\nThe value is %d', someVariable);
set(handles.text1, 'String', myString);
drawnow; % Needed only if this is in a fast loop.

@image analyst: your code is more simple. thanks sir !

[Image Analyst]

It's even simpler if you use OOP syntax:

handles.text1.String = myString;  % Do it like this instead of using set()

Is there a way to permanently edit the static text, so that when launch the GUI again some other time, the text will be the updated one?

[Image Analyst]

You can save the new value in a .mat file,

save('app settings.mat', 'myString');

then when your startup code runs again, load() the mat file and assign the prior/saved string to the control.

myString = load('app settings.mat', 'myString'); % Get string from mat file.
handles.text1.String = myString; % Send string to static text control on GUI.

Thanks, I was planning to save the string in a text file, This seems like a better idea.

If you want to bind the defaults to your copy of Matlab instead of the current folder, you can use setpref and getpref.

A very basic example:

f = figure;
t = uicontrol(f,'Style','text',...
    'String','Select a data set.',...
    'Position',[30 50 130 30]);
t.String = 'hello World';

This changes the static text from 'Select a data set.' to 'hello World'

Basically, all you are doing is changing the string property in an object that is of style text .

Does that help?
