delete function doesnt work

function names_Callback(hObject, eventdata, handles)
  d=get(handles.textvis,'Value');
  if d==1
    delete (handles.texthandles(:));
  end

I tried deleting some handle objects, depending on the value of d, but it didnt work.

P.S.- it worked well when i didnt had this 'if loop'. I am not able to detect the problem.

Did you look at the value of d? Perhaps it is not 1... Take the semicolon off, see what prints to the command window when you trigger that callback.

P.S. There is no such thing as an "if loop", only "if statements."

[Walter Roberson]

The "textvis" is suggestive that it might be a uicontrol('Style','text'), in which case Value would be meaningless ('String' being meaningful but non-numeric)

[Matt Fig]

I agree, the value is not set by the uicontrol if it is an editbox or a text. But Shree may be using it as a switch by setting it in another callback or whatever. I have only guesses as to what is going on due to a lack of details in the OP...

@Matt : I tried displaying the value.. it is 1 each time, yet this isnt working. Is there any other way to do it? P.S.- Oopsy :P

@Walter -that is taken care of..this is a variable depicting the handles visiblity, taking values 0 and 1. This works well. Problem is with deleting function.

[Walter Roberson]

Put in a breakpoint at the delete() call. Do you reach that point?

If it is "a variable depicting the handles visibility", then is it a uicontrol() and if so what Style is it? If it isn't a handle graphics handle, then get() is not appropriate for it.

Try displaying d-1 to see whether the value might be near 1 but not exactly equal to it.

[Shree Nath]

I made textvis as a variable stored in handles structure, accordingly changed the code, but still no good.

i see the problem... compiler doesnt reach that point.
