it took me the entire afternooon to get an idea of what those red thin linnes a "thumb" bar were. i think it was only in ubuntu... and i have fixed parts of it.
now i have two separate horizontal scrollbars. they range from 0 to 100 exactly what i want. and now, in place of that red line is a regular groove with a tab inside that you slide to and fro. my quandry is how to move the first grove up beneath the first scollbar with a "0"? do i need another box--a box4? i have tried a number of things, but nothing works. can anybody help me? thanks in advance, gary code appended below my sig. -- Gary Kline kl...@thought.org http://www.thought.org Public Service Unix ======= #include <stdio.h> #include <gtk/gtk.h> GtkWidget *hscale, *hscale7; void scale_set_default_values (GtkScale *scale) { //gtk_range_set_update_policy (GTK_RANGE (scale), GTK_UPDATE_CONTINUOUS); gtk_scale_set_digits (scale, 0); // Zero digits after N. gtk_scale_set_value_pos (scale, GTK_POS_TOP); gtk_scale_set_draw_value (scale, TRUE); } /* * creates the sample window */ void create_range_controls (void) { GtkWidget *window; GtkWidget *box1, *box2, *box3; GtkWidget *button, *quitbox; GtkWidget *scrollbar, *scrollbar7; GtkObject *adj1, *adj7; /* Standard window-creating stuff */ window = gtk_window_new (GTK_WINDOW_TOPLEVEL); gtk_window_set_position (GTK_WINDOW (window), GTK_WIN_POS_CENTER); gtk_window_set_default_size (GTK_WINDOW (window), 350, 450); g_signal_connect (GTK_OBJECT (window), "destroy", GTK_SIGNAL_FUNC (gtk_main_quit), NULL); gtk_window_set_title (GTK_WINDOW (window), "two horiz bars"); box1 = gtk_vbox_new (FALSE, 0); gtk_container_add (GTK_CONTAINER (window), box1); gtk_widget_show (box1); box2 = gtk_hbox_new (FALSE, 10); gtk_container_set_border_width (GTK_CONTAINER (box2), 10); gtk_box_pack_start (GTK_BOX (box1), box2, TRUE, TRUE, 0); gtk_widget_show (box2); /* value, lower, upper, step_increment, page_increment, page_size */ /* Note that the page_size value only makes a difference for * scrollbar widgets, and the highest value you'll get is actually * (upper - page_size). */ adj1 = gtk_adjustment_new (0.0, 0.0, 101.0, 0.1, 1.0, 1.0); adj7 = gtk_adjustment_new (0.0, 0.0, 101.0, 0.1, 1.0, 1.0); box3 = gtk_vbox_new (FALSE, 10); gtk_box_pack_start (GTK_BOX (box2), box3, TRUE, TRUE, 0); gtk_widget_show (box3); /* Reuse the same adjustment BAR-1*/ hscale = gtk_hscale_new (GTK_ADJUSTMENT (adj1)); gtk_widget_set_usize (GTK_WIDGET (hscale), 200, -1); scale_set_default_values (GTK_SCALE (hscale)); gtk_box_pack_start (GTK_BOX (box3), hscale, TRUE, TRUE, 0); gtk_widget_show (hscale); /**** BAR-2 ****/ hscale7 = gtk_hscale_new (GTK_ADJUSTMENT (adj7)); gtk_widget_set_usize (GTK_WIDGET (hscale7), 200, -1); scale_set_default_values (GTK_SCALE (hscale7)); // box 3 and 7 gtk_box_pack_start (GTK_BOX (box3), hscale7, TRUE, TRUE, 0); gtk_widget_show (hscale7); /* Reuse the same adjustment again */ scrollbar = gtk_hscrollbar_new (GTK_ADJUSTMENT (adj1)); //scrollbar7 = gtk_hscrollbar_new (GTK_ADJUSTMENT (adj7)); /* Notice how this causes the scales to always be updated * continuously when the scrollbar is moved */ gtk_range_set_update_policy (GTK_RANGE (scrollbar), GTK_UPDATE_CONTINUOUS); // box 3 and bar gtk_box_pack_start (GTK_BOX (box3), scrollbar, TRUE, TRUE, 0); gtk_widget_show (scrollbar); scrollbar7 = gtk_hscrollbar_new (GTK_ADJUSTMENT (adj7)); gtk_range_set_update_policy (GTK_RANGE (scrollbar7), GTK_UPDATE_CONTINUOUS); // box 3 and bar7 gtk_box_pack_start (GTK_BOX (box3), scrollbar7, TRUE, TRUE, 0); gtk_widget_show (scrollbar7); box2 = gtk_hbox_new (FALSE, 10); gtk_container_set_border_width (GTK_CONTAINER (box2), 10); gtk_box_pack_start (GTK_BOX (box1), box2, TRUE, TRUE, 0); gtk_widget_show (box2); /**** END of horizontal bar stuff ****/ quitbox = gtk_vbox_new (FALSE, 10); // WAS "box2" reused gtk_container_set_border_width (GTK_CONTAINER (quitbox), 10); /**** "box1" below, so this button fits into the overall Window ****/ gtk_box_pack_start (GTK_BOX (box1), quitbox, FALSE, TRUE, 0); gtk_widget_show (quitbox); button = gtk_button_new_with_label ("Quit"); gtk_signal_connect_object (GTK_OBJECT (button), "clicked", GTK_SIGNAL_FUNC (gtk_main_quit), NULL); gtk_box_pack_start (GTK_BOX (quitbox), 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); } int main (int argc, char *argv[]) { gtk_init (&argc, &argv); create_range_controls (); // Handles windows and h-bars gtk_main (); return (0); } _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
