Help: Display a different layout when pushing a button in a GUI?

Hi all,

I'm trying to write a programmatic GUI. It includes a push button and a edit text named "tab1" when it initializes. Then when I hit the button the edit text "tab1" will be hidden and the GUI will show the edit text "tab2" which was invisible before hitting the button. I also attached my code which doesn't work.

Any help would be greatly appreciated.

Thanks.

Which Matlab version are you using?

Hi Robert

I'm using MATLAB 2014a.

Answer 1

The reason your code doesn;t work - is that when the callback for the pushbutton is created the variable S.tab1 doesn't exist. If you moved the pushbutton creation to the end then it would work.

It looks like you are trying to build a GUI with tabs?

If you looking for an off the shelf solution look here

I'm trying to build a GUI with multi tab. Really thank you. I moved the set callback for the push button on the callback function line immidiately, it worked.

Thanks for your addtional advice.

Didn't see your code. In your push button callback function write: set("edit box id",'String','tab2'), where "edit box id" is your edit box identifier (It appears when you create it.)

The attached file is OK. But I also post it in comment. Please examine and figure out my mistake.

[Mikhail]

function []=pushbutton1_Callback(varargin) %#ok<INUSD>

S=varargin{3}

       %set(S.tab1,'visible','off')

This is your pushbutton callback function. To make your tab2 visible write inside: set(S.tab2,'visible','on')

To make your tab1 invisible write inside:

set(S.tab1,'visible','off')

Note: you might have problem with arguments. Either use global variables (callback function is inside your main function) or at the step where you define your callback function for pushbutton insert additional arguments S.tab1, S.tab1

Hi Mikhail

Thanks for you answers.

Although I used both ways, it doesn't work. I went around whole day but I still don't understand my problem.

[Mikhail]

Hi, no problem. What I recommend to you is to download something in Matlab exchanger and use it as a template for a first time, before you get enough experience.
