Re: button label problem

[Daniel Carrera <dcarrera math toronto edu>]

Here is one idea.

Use a global variable to keep track of which label you have on, and keep
the label global as well so you can change it.

1.- gtk_signal_connect to connect the "clicked" signal to a callback.

2.- The callback receives the button widget as an argument.

3.- gtk_label_set_text


I know that there's a better solution, but I can't think of it.  I really
hate global variables.  Perhaps you can improve upon my suggestion.

Perhaps you can try to obtian the label from the button, and get the text
from the label.  This would eliminate both globals.
