MATLAB GUI (Graphical User Interface) Tutorial for Beginners

Troubleshooting and Potential Problems

So your GUI doesn’t work and you don’t know why. Here are a couple of tips that might help you find your bug:

If you can’t figure out where you error is, it might be a good idea to quickly go through this tutorial again.
The command line can give you many hints on where exactly the problem resides. If your GUI is not working for any reason, the error will be outputted to the command prompt. The line number of the faulty code and a short description of the error is given. This is always a good place to start investigating.
Make sure all your variable names are consistent in the code. In addition, make sure your component Tags are consistent between the .fig and the .m file. For example, if you’re trying to extract the string from the Edit Text component, make sure that your get statement uses the right tag! More specifically, if you have the following line in your code, make sure that you named the Edit Text component accordingly!
```
a = get(handles.input1_editText,'String');
```
The source code is available here, and could be useful for debugging purposes.
If all else fails, leave a comment here and we’ll try our best to help.

Thanks for the tutorial - its nice and clear

Extremely useful. Can you add a further tutorial on how to plot data in a set of axes in the GUI?
on 28 Nov 2007 at 12:36 pm 3Quan Quach

You can find the tutorial on plotting data to a set of axes here.

You can find a list of matlab tutorials here.

First of all, I greatly appreciate these tutorials. I have found the Matlab documentation simply unreadable on the subject of GUIs, and your approach with simple examples and easily modified code is perfect.

I was having some success with KeyPressFcn to make a graph with live keyboard input. Is there any way to integrate this into a graph in a GUI? Or alternatively, have a GUI running simultaneously with a live figure responding to KeyPressFcn?
on 28 Nov 2007 at 4:06 pm 5Quan Quach

Hello Fred,

I’m not sure if I’m understanding your question exactly, but I’ll try to answer it anyways.

If you look here, it’ll show you how to enter the command line mode so that you can modify any of the GUI’s components in real time, including the axes.

But I think you may be asking something different. Are you asking if there is a way to press a particular key, say “e”, and have it populate the axes on a GUI with a plot? I’d love to help, so if you can clarify your question, I will be in better shape to answer!

Hi!,
First of all, myAdder GUI tutorial very useful for beginner like me. but I have a question, is it possible to send let say; sine wave plot from one GUI window to another GUI window via UDP IP connection (using same computer)?
thanks,

Hello Quan,

Great tutorial, loved it!

I’m having a problem similar to Fred’s here (I think). I am trying to create a GUI that displays an image, and a pointer (little cross or whatever) to a current point (x,y). I want the cursor position to respond to key strokes (arrows), and various shortcuts (say ‘Ctrl+F’ for toggling a filter, ‘r’ for refresh, etc.).

I know how to implement the movement of the cursor on the image, but don’t know how to trigger it with the keystrokes.

Regards,

Gil

Zuri:

I’m a little confused on what you’re trying to accomplish, if you can elaborate then perhaps I might have an answer.

Gil:

I emailed you some code that I developed to explain this. I will probably turn this into a tutorial in the immediate future

Hi - I am very new to Matlab (7.0) and climbimg the steep learning curve. I contructed your Gui and works fine and I think I understand the basic parts of your GUI code. I think it was nicely put together and very understandable.

Two questions though:

1) Your first added code block, ‘input = str2num(get(hObject,’String’));’ shows the variable ‘input’ and ’str2num(get’ in blue type. My editor shows these in black type ?? I have looked at the preference settings but cannot change this - but the code works and no errors. I think your screen shot more clearly defines the variable name by its blue color - any ideas?

2) I am quite confused on the ‘handles’ versus ‘hObject’ - Am I right in thinking ‘handles’ are for data being sent somewhere else and ‘hObject’ for data being received? - I am still trying to understand terminology and syntax.

Anyway - tks for you time - guys like you make it easier for guys like me!

Hi Dave,

1) The coloring scheme is a little bit off due to the wordpress plugin that I use.

2) The handles structures contain’s all the information about all of the GUI’s objects. hObject on the other hand, is the active object from which the callback is called.

So for example, if I pressed the “add” button, hObject in this case is the “add” button object.

Another example. When I input a number into the left edit text field, hObject is the edit text object.

There are a bunch of other tutorials that you can find on this website. I recommend taking a look at this one for a better understanding:

Hi my friend.
Nice work , and very thank’s to you disponibility to make this tutorials.
I spend a few hours to make some things that you have here in your site, now i can found and i can see that i’m a good way.
But i have a little thing that i want to make better, so i have a edit text box where i write the 3 digits of a IP address(0…255), so my ideia is to make a limit os 3 chars on this edit text box.
I used the KeyPressFcn to count a number of pressed keys and compare it to 0..9 if is backspace or delete e decraise one number of this count.
After when i will read the data of all edit boxs i compare the text of the edit box with 0…255 and if is a letter os >255 o put ‘0′.
But also with this things isn’t perfect.
I search a lot in help of matlab, and also in internet, but i can’t found any info to make something like this.
Now how i have this i’m satisfied, but if i can make better i will more happy
So if you can give me any trick or any ideia, or any link to internet i will very appreciated.
Very tahnk’s to your pacience.
String regards,

download the source files. place them into a directory.

make sure the matlab current directory is the same as above

at the command prompt,

type:
```
myAdder
```
Please give that a try

Thank you very much for the tutorial. From now on, I am ready to make GUI on matlab..

But, I would like to ask you some question.

How to make a GUI that connects to simulink (*.mdl)?
It’s like if you want to make GUI to take the data (input), and do the process in simulink.

How to do that?

Thank you very much..

Hi,

in my code i have the following:
[time,number,pressure,raininput] = textread(’rain.txt’,'%s %d %f %f’,'delimiter’,',’,'headerlines’,4);

my question is how do i get the user to view the array time, and from that select the range they require? (preferably in listbox- so i can use for a gui plot)

e.g they would only require the data from the 5th row til the end. ( however they shouldn’t see the row no,but only the date)

I have’nt clue if this is even possible.

any help would be really appreciated.

on 11 Apr 2008 at 10:52 pm 41Jim

Nice. One of the first GUI tutorials I’ve seen that wasn’t too simple, or too advanced. A large amount of MATLAB users don’t code with GUI’s because the process was never clearly explained to them. This tutuorial is simple and CLEAR.

Your tutorial is very helpfull but I can’t do what I need with my GUI.
Breefly:
I need to load a signal (this is the main part of the problem) with a pusbutton. This signal consist on a matrix with n rows and m columns,then I want to plot each row with another pushbutton. And finaly a want to plot the diffrence between any combination of two rows.
The code is the following:

function varargout = visualizador(varargin)
% VISUALIZADOR M-file for visualizador.fig
%      VISUALIZADOR, by itself, creates a new VISUALIZADOR or raises the existing
%      singleton*.
%
%      H = VISUALIZADOR returns the handle to a new VISUALIZADOR or the handle to
%      the existing singleton*.
%
%      VISUALIZADOR('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in VISUALIZADOR.M with the given input arguments.
%
%      VISUALIZADOR('Property','Value',...) creates a new VISUALIZADOR or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before visualizador_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to visualizador_OpeningFcn via varargin.

on 25 Aug 2008 at 5:37 pm 64Quan Quach

Use the addpath command in the opening function of your main gui.

The addpath command will add a path to the list of MATLAB paths and enable you to run scripts/guis from a different path other than the current matlab directory.
