Sad, as I remember, starting from some version gtk+ supports only
windows > windows 98, and I suppose 2.10 is this version.

Great.

The last problem is, if you trys example, you see that
in line "aaa Link",
the "Link" and "aaa" is not on the same line,
can GtkTextView care about anchors automaticaly, or I should do it by my self?
I don't find API to get height of line in GtkTextView to resize button to it,
and interesting what happend if there are no text, only anchors on line,
is it climb on the next line?

Here is updated example:


#include <cstdlib>
#include <gtk/gtk.h>

static void on_link(GtkButton *button, gpointer) { g_debug("on_link\n"); }

int main(int argc, char *argv[])
{
 gtk_init(&argc, &argv);

 GtkWidget *topLevelWindow=gtk_window_new(GTK_WINDOW_TOPLEVEL);

 g_signal_connect(G_OBJECT(topLevelWindow), "delete_event",
                  G_CALLBACK(gtk_false), NULL);
 g_signal_connect(G_OBJECT(topLevelWindow), "destroy",
                   G_CALLBACK(gtk_main_quit), NULL);
 GtkTextView *tv = GTK_TEXT_VIEW(gtk_text_view_new());
 gtk_container_add(GTK_CONTAINER(topLevelWindow), GTK_WIDGET(tv));
 GtkLabel *lab = GTK_LABEL(gtk_label_new(NULL));
 gtk_label_set_markup(GTK_LABEL(lab),
                       "<span underline=\"single\" foreground=\"blue\">Link</span>");
 GtkButton *bt = GTK_BUTTON(gtk_button_new());
 gtk_container_add(GTK_CONTAINER(bt), GTK_WIDGET(lab));
 gtk_button_set_relief(bt, GTK_RELIEF_NONE);
 g_signal_connect(G_OBJECT(bt), "clicked", G_CALLBACK(on_link), NULL);
//  gtk_container_add(GTK_CONTAINER(topLevelWindow), GTK_WIDGET(bt));

 GtkTextBuffer *buffer = gtk_text_view_get_buffer(tv);
 GtkTextIter iter;
 gtk_text_buffer_get_iter_at_offset(
   buffer, &iter, 0
 );
 gtk_text_buffer_insert(buffer, &iter, "aaa ", -1);
 GtkTextChildAnchor *anchor =
          gtk_text_buffer_create_child_anchor(buffer, &iter);
 gtk_text_buffer_insert(buffer, &iter, "\nbbb", -1);
 gtk_text_view_set_editable(tv, FALSE);
 gtk_text_view_add_child_at_anchor(tv, GTK_WIDGET(bt), anchor);

 gtk_widget_show_all(topLevelWindow);
 gtk_main();

 return EXIT_SUCCESS;
}
