RE: how to justify text in a GtkTextView

["Boncek, John" <jboncek Hunter COM>]

I don't know what that could be.  This is a very simple trial program, to
put a GtkTextView in a scrolled window with justification.

My version of GTK is 2.2.4, as listed by pkg-config.

Here's the entire program, some of which was pieced together from various
online examples:

#include <stdio.h>
#include <stdlib.h>
#include <gtk/gtk.h>


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

    GtkWidget *window;
    GtkWidget *vbox;
    GtkWidget *button;

    gtk_init (&argc, &argv);

    // create a new window
    window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
    gtk_widget_set_size_request (GTK_WIDGET (window), 300, 300);
    gtk_window_set_title (GTK_WINDOW (window), "GTK Text View");
    g_signal_connect (G_OBJECT (window), "destroy",
                      G_CALLBACK (gtk_main_quit), NULL);
    g_signal_connect_swapped (G_OBJECT (window), "delete_event",
                              G_CALLBACK (gtk_widget_destroy), 
                              G_OBJECT (window));

        // create VBox
    vbox = gtk_vbox_new (FALSE, 0);
    gtk_container_add (GTK_CONTAINER (window), vbox);
    gtk_widget_show (vbox);

        /* create a new scrolled window. */
        GtkWidget *             scrolled_window         =
gtk_scrolled_window_new (NULL, NULL);
        /* the policy is one of GTK_POLICY AUTOMATIC, or
GTK_POLICY_ALWAYS.
        * GTK_POLICY_AUTOMATIC will automatically decide whether you need
        * scrollbars, whereas GTK_POLICY_ALWAYS will always leave the
scrollbars
        * there. The first one is the horizontal scrollbar, the second,
        * the vertical. */
        gtk_scrolled_window_set_policy (GTK_SCROLLED_WINDOW
(scrolled_window),
        
GTK_POLICY_AUTOMATIC, GTK_POLICY_AUTOMATIC);
        gtk_box_pack_start (GTK_BOX (vbox), scrolled_window, TRUE, TRUE,
0);
    gtk_widget_show (scrolled_window);

        // create TextView
        GtkTextView *           view;
        GtkTextBuffer *         buffer;
        view = GTK_TEXT_VIEW(gtk_text_view_new());
        buffer = gtk_text_view_get_buffer(view);
        gtk_text_view_set_justification (view, GTK_JUSTIFY_CENTER);
        gtk_text_buffer_set_text (buffer, "some initial text", -1);
        
//      GtkTextIter             start;
//      GtkTextIter             end;
//
//      gtk_text_buffer_get_start_iter(buffer, &(start));
//      gtk_text_buffer_get_end_iter(buffer, &(end));
//      gtk_text_buffer_remove_all_tags (buffer, &(start), &(end));

        gtk_container_add(GTK_CONTAINER (scrolled_window), (GtkWidget
*)(view)); 
    gtk_widget_show((GtkWidget *)(view));

        // create Close button
    button = gtk_button_new_from_stock (GTK_STOCK_CLOSE);
    g_signal_connect_swapped (G_OBJECT (button), "clicked",
                              G_CALLBACK (gtk_widget_destroy),
                              G_OBJECT (window));
    gtk_box_pack_start (GTK_BOX (vbox), button, TRUE, TRUE, 0);
    GTK_WIDGET_SET_FLAGS (button, GTK_CAN_DEFAULT);
    gtk_widget_grab_default (button);
    gtk_widget_show (button);
    
    gtk_widget_show (window);

    gtk_main();

    return 0;
}

Hmm, works fine here. Are you doing something after insterting the text 
that could affect the justification?
