[scilab-Users] Graphic interfaces

[Vincent COUVERT]

Hi Jean-Louis,

Your callback functions must not take input arguments because when they 
are called, "B_style" and "A_style" are undefined.

The good way to manage your test case is to identify your buttons using 
a tag (see the tag property), then using findobj to get them in your 
callback functions and finally setting the string value.

// Creation
A_style.tag = "A_style"

// Callback function
A_style = findobj("Tag", "A_style");
A_style.string = "B";

Regards,
Vincent
