button to activate textboxes in GUI

Hi: How can i make it so that when i click on a button, it gathers information in textbox(s)? I have get(hObject, 'string') for my textbox, but how do i link this to another button? Thanks

Use this:

      exportwhatever = get(handles.("textboxname"),'string')

Put this code in the function callback. It will go to the text box and return in string format what is in the textbox.

thanks, exactly what i needed

I used the function above but I still get an error:

"Undefined variable "handles" or class "handles.text1". Text1 is the tag of my textbox. But, i do not understand how to access the handles from my textbox.

I tried

set(handles.text1, 'String', works);

where works is just a string. So, how do I get to recognize "handles" from my textbox in my button callback function

You have to create callback function:

I have a callback function for the textbox, i try to call it from the button function but its not working, can you give me an simple example?

function test

uicontrol('Style','pushbutton','String','read','callback',@pb_clbck)

h = uicontrol('Style','Edit','String','write me!',...

'Units','normalized','Position',[.4 .45 .2 .1]);

function pb_clbck(src,evnt)

disp(get(h,'String'))

end

end
