How do I, from choosing a string from a pop-up menu, make a edit box disable?

Hi

Ive been looking for a guide to how to make a gui pop-up menu make one of my edit box disable?

Seen alot of good guides with a push button, but I need one for a pop-up menu.

Il'l try to make a image of what i need.

(Pop-up menu) | Edit 1 | | Edit 2 |

if I in pop-up menu pick option 1, I want edit box 2 to be disablet. And if i pick option 2, i want edit box 1 to be disablet.

How do I do that?

   idx = get( hObject, 'Value')
   switch idx
     case 1: set( handles.Editbox1, 'Enable', 'off');
     case 2: set( handles.Editbox2, 'Enable', 'off');
   end

It does the first thing right, with i choose option 2, the editbox1 gets disablet, but when i go back to option 1, the editbox 1 is still disablet, and nothing has happend to editbox 2.

Im new at this gui, so please explain it in "small" words. Or just type the code.

Your question only asked for boxes to be disabled, not for the other one to be enabled ;-)

idx = get( hObject, 'Value')

switch idx

case 1: set( handles.Editbox1, 'Enable', 'off'); set( handles.Editbox2, 'Enable', 'on');

case 2: set( handles.Editbox2, 'Enable', 'off'); set( handles.Editbox1, 'Enable', 'on');

end

Yeah sorry :)

But still, dont know if I'm doing anything wrong, because its still only the editbox 1 that is disablet, nothing is happening to editbox 2. And even though I change my pop-up menu to option 2, its still editbox 1 that is disablet.

I dont know if I havent explained cleary enough what I would like. But I would like that option 1 disables editbox 2 and enables editbox 1, and option 2 disables editbox 1 and enables editbox 2.

Does that make any sence?

dx = get( hObject, 'Value')

switch idx

case 1: set( handles.Editbox1, 'Enable', 'on'); set( handles.Editbox2, 'Enable', 'off');

case 2: set( handles.Editbox2, 'Enable', 'on'); set( handles.Editbox1, 'Enable', 'off');

end

I still get an error, where do I put this code, ive placed it under the pop-up menu, but is that correct?

??? Reference to non-existent field 'Editbox1'.

Error in ==> guiproblem>popupmenu1_Callback at 86

case 1: set( handles.Editbox1, 'Enable', 'on'); set( handles.Editbox2, 'Enable', 'off');

??? Error while evaluating uicontrol Callback

I cant understand why it says that Editbox1 doesnt excist. Because it does...

[Walter Roberson]

At the command line, command

dbstop if error

Then run your program. When it stops, examine

fieldnames(handles)

Check the names carefully. For example is it "editbox1" (with lower-case) in the handles structure ?

Instead of me trying a million things and not getting anywhere, could you make a simple gui with 1 pop-up menu and 2 edit boxes, and just make them do what I would like to do, and then send the files to [e-mail]

Would really really really appreciate it :)
