Re: more of a C question than GTK+3.0??

[Gergely Polonkai <gergely polonkai eu>]

What I would do instead is:

GtkWidget **label[1000]; // if you have a dynamic number of labels,
consider using a GArray maybe
int i = 0;

label[i++] = gtk_label_new("first text"); // this will be label[0]
label[i++] = gtk_label_new("second text"); // this will be label[1]
…

After this, instead of creating a string "label1", you just need the
number 1, and can use this:

s = gtk_label_get_text(GTK_LABEL(label[1]));

where 1 can instead be a variable of int that holds 1:

int num = 1;
s = gtk_label_get_text(GTK_LABEL(label[num]));
