How do i put content in a text box into a list in GUI?
Show older comments
I am trying to put content inside a text box into a list. So i make a list, namelist = cell(2,6),
and then i did
namelist(1,2) = get(hObject, 'String')
for every text box i have (number inside different)
but when i run my GUI it keeps on giving me weird numbers, i enter 1 number, it gives me like 50s or 60s or even 100s for every number in the list. If i try to input something that is 2 letters, for example "12", it gives me error saying dimesion mismatch. If anyone knows what i am doing wrong please help! Thanks

You need to use namelist{1,2} = get(hObject, 'String')
Notice the curly bracket {}, instead of parentheses ()

I sense you need some basics about GUI programming.
Are you trying to put the content of an "Edit" to an "Listbox"? The "Edit" and "Listbox" here refer to the "style" when you use uicontrol('style','Edit') or uicontrol('style','Listbox'). You can also do that through GUIDE, which is the element you drag and drop from the GUI palette.

Okay, first let's try to get rid of the error. You have many textbox. Every textbox will have a callback function. In the callback function, you run namelist=cell(2,6);namelist{i,j}=get(hObject,'String'); i and j vary depending on which textbox. It should not have error has long as i is 1 or 2. j is any number from 1 to 6. Remember though, you won't be able to combine all the text into namelist because you are not saving and passing data yet. Every time you edit the textbox, it's going to set one cell in namelist and then namelist is lost. You can only see the value change when you debug. But anyway, what is your error message?

Just to clarify--you have the textbox in a GUI, and you want to put all numbers from the text box into a list? If it's a list of numbers you want, you might need to use the str2num or str2double function so that you don't get a dimension mismatch since what you're getting from the GUI is a string.
At least, that's what I think. If that doesn't do anything, what exactly is the error that you get?

Could you assign get(hObject, 'String') to a variable, then find out what class that variable is for me? Just say, a = get(hObject, 'String') and type class a in the command editor.
Thanks!

OK, good. If your numlist is a cell, and you assign numlist{x,y} (with curly braces) to anything, there shouldn't be an assignment mismatch. I saw above that you get an error when you try to assign it this way--what's that error?

No worries--it always seems to end up being something that simple.
