About gtk_label_set_text()

[Antonio Martínez Álvarez <newton retemail es>]

Hello list:

I'm trying to write a simple application. One button with label "1", and
every time the user do a click on it, the label must increase the label
by one. 1 --> 2 --> 3 etc...

I have found that I only can use a const string
(gtk_label_set_text(label, "anything") but no way to do what I say. How
can I do that.

Thank you. Sorry for my english.
