I have a gui written in GTK, and i need the buttons to perform certain tasks.

If i have one button like this

g_signal_connect (G_OBJECT (button), "clicked", G_CALLBACK (callback), (gpointer) "button 1");

and the callback looks like this

static void callback( GtkWidget *widget, gpointer data )
{
}

How do i get the callback function in to check a boolean in my main, and then if it is = true, add the "button 1" string of chars to another string? Do i have to add a second connect statement to the button and pass a pointer to the boolean?

Any help appreciated.
