Single- and Multi-line Edit Controls

Question

I'm writing a GUI in GUIDE but when I open it and when I perform an action I keep getting this warning:

Warning: Single line Edit Controls can not have multi-line text 
> In openfig at 135
  In gui_mainfcn>local_openfig at 286
  In gui_mainfcn at 234
  In Var_final at 42 
Warning: Single line Edit Controls can not have multi-line text 
Warning: Single line Edit Controls can not have multi-line text 

Is it a problem? I've read you need to set the Max value to 2, but the warnings seem to persist.

What can I do?

Answer 1

Take a look at the documentation for the properties of uicontrols. You can set the Max and Min properties of an edit box. I know it seems crazy, but if Max - Min > 1, the edit box will accept multiline input; if Max - Min <= 1, it is single line only. Otherwise, the Max and Min properties have no effect on edit box controls.
