Re: GTK window positioning [SOLVED]

[David Buchan <pdbuchan yahoo com>]

Oh ho!

Break through.

I noticed that if, elsewhere in my program I ask it to open a second window, it opens it into a different 
location.
This got me thinking that, as usual, I'm not letting GTK main iteration do what it needs to do.
So, adding this between the two gtk_widget_show_all() instances:

      // Check for pending GTK click events.
      while (gtk_events_pending ()) {
        gtk_main_iteration ();
      }

allows the window manager time to come up with a new location, and it now opens the windows in different 
locations.

It just occurred to me that maybe I should be sending to the gtk-list mailing list instead (more active).

Pls see below...

Hi,

I've made a program that creates two new windows when demanded:

  GtkWidget *window1, *scrolled_win1, *textview1;
  GtkTextBuffer *buffer1;
  GtkWidget *window2, *scrolled_win2, *textview2;
  GtkTextBuffer *buffer2;
  PangoFontDescription *textview_font1;
  PangoFontDescription *textview_font2;

// Create new window to display unfragmented packet.
  window1 = gtk_window_new (GTK_WINDOW_TOPLEVEL);
  gtk_window_set_resizable (GTK_WINDOW (window1), TRUE);
  gtk_window_set_position (GTK_WINDOW (window1), GTK_WIN_POS_NONE);
  gtk_window_set_title (GTK_WINDOW
 (window1), title);
  gtk_window_set_default_size (GTK_WINDOW (window1), 1000, 200);
  gtk_container_set_border_width (GTK_CONTAINER (window1), 1);

// Create a textview object to display unfragmented packet.
  textview1 = gtk_text_view_new ();
  buffer1 = gtk_text_view_get_buffer (GTK_TEXT_VIEW (textview1));
  gtk_text_view_set_cursor_visible (GTK_TEXT_VIEW (textview1), TRUE);
  textview_font1 = pango_font_description_from_string ("Courier 10 Pitch 12");
  gtk_widget_modify_font (textview1, textview_font1);

// Create new window to display fragmented packet.
  window2 = gtk_window_new (GTK_WINDOW_TOPLEVEL);
  gtk_window_set_resizable (GTK_WINDOW (window2), TRUE);
  gtk_window_set_position (GTK_WINDOW (window2), GTK_WIN_POS_NONE);
  gtk_window_set_title (GTK_WINDOW (window2), title);
  gtk_window_set_default_size (GTK_WINDOW (window2), 1000,
 200);
  gtk_container_set_border_width (GTK_CONTAINER (window2), 1);

// Create a textview object to display fragmented packet.
  textview2 = gtk_text_view_new ();
  buffer2 = gtk_text_view_get_buffer (GTK_TEXT_VIEW (textview2));
  gtk_text_view_set_cursor_visible (GTK_TEXT_VIEW (textview2), TRUE);
  textview_font2 = pango_font_description_from_string ("Courier 10 Pitch 12");
  gtk_widget_modify_font (textview2, textview_font2);

I then do some stuff and then display the buffers within textviews within scrollbars within windows:

  scrolled_win1 = gtk_scrolled_window_new (NULL, NULL);
  gtk_container_add (GTK_CONTAINER (scrolled_win1), textview1);
  gtk_scrolled_window_set_policy (GTK_SCROLLED_WINDOW
 (scrolled_win1),
                                  GTK_POLICY_AUTOMATIC, GTK_POLICY_ALWAYS);

  gtk_container_add (GTK_CONTAINER (window1), scrolled_win1);
  gtk_widget_show_all (window1);

  scrolled_win2 = gtk_scrolled_window_new (NULL, NULL);
  gtk_container_add (GTK_CONTAINER (scrolled_win2), textview2);
  gtk_scrolled_window_set_policy (GTK_SCROLLED_WINDOW (scrolled_win2),
                                  GTK_POLICY_AUTOMATIC, GTK_POLICY_ALWAYS);

  gtk_container_add (GTK_CONTAINER (window2), scrolled_win2);
  gtk_widget_show_all
 (window2);

I find that the two windows are always placed right on top of each other. I can drag the top one off the one 
underneath, but I'd like the window manager to choose placements that are separate.

Suggestions? Have I bungled something?


Thanks,
Dave
