Da für die vertikale Scrollbox dasselbe gilt wie für die Horizontale, wollen
wir diese Thema recht kurz halten. Zuerst die Funktion mit der wir eine
Vertikale Box erstellen:
GtkWidget *gtk_hscrollbar_new(GtkAdjustment *adj);
Und noch das Programmbeispiel dazu:
/*Download:gtkscr4.c*/ #include <gtk/gtk.h> void ende_cb(GtkObject *object) { gtk_main_quit(); } void scrollbar_cb(GtkAdjustment *adj, gpointer user_data) { g_print("%s hat sich verändert ",(char *)user_data); g_print("neue Pos. : %f\n", adj->value); } int main(int argc, char **argv) { GtkWidget *fenster; GtkWidget *box, *box2; GtkWidget *hscrollbar1, *hscrollbar2, *hscrollbar3; GtkWidget *button_quit; GtkObject *adj1, *adj2, *adj3; /*Gtk initialisieren*/ gtk_init(&argc, &argv); /*Ein neues Fenster erstellen*/ fenster = gtk_window_new(GTK_WINDOW_TOPLEVEL); /*Buttons erstellen*/ button_quit = gtk_button_new_with_label("Ende"); /*Neue Box erstellen*/ box = gtk_hbox_new(FALSE,10); box2= gtk_vbox_new(TRUE,0); adj1 = gtk_adjustment_new(50.0, 0.0, 100.0, 0.1, 1.0, 1.0); adj2 = gtk_adjustment_new(0.0, 0.0, 100.0, 10.0, 1.0, 1.0); adj3 = gtk_adjustment_new(0.0, 0.0, 100.0, 1.0, 1.0, 50.0); hscrollbar1 = gtk_vscrollbar_new(GTK_ADJUSTMENT(adj1)); hscrollbar2 = gtk_vscrollbar_new(GTK_ADJUSTMENT(adj2)); hscrollbar3 = gtk_vscrollbar_new(GTK_ADJUSTMENT(adj3)); /*Signale registrieren*/ gtk_signal_connect_object(GTK_OBJECT(button_quit), "clicked", GTK_SIGNAL_FUNC(ende_cb), GTK_OBJECT(fenster)); gtk_signal_connect(GTK_OBJECT(fenster), "destroy", GTK_SIGNAL_FUNC(ende_cb), NULL); gtk_signal_connect(GTK_OBJECT(adj1), "value_changed", GTK_SIGNAL_FUNC(scrollbar_cb), "Scrollbar 1"); gtk_signal_connect(GTK_OBJECT(adj2), "value_changed", GTK_SIGNAL_FUNC(scrollbar_cb), "Scrollbar 2"); gtk_signal_connect(GTK_OBJECT(adj3), "value_changed", GTK_SIGNAL_FUNC(scrollbar_cb), "Scrollbar 3"); /*Fensterposition*/ gtk_window_set_position(GTK_WINDOW(fenster),GTK_WIN_POS_CENTER); gtk_container_set_border_width(GTK_CONTAINER(fenster),25); /*Nun alles rein in die Box....*/ gtk_box_pack_start(GTK_BOX(box), hscrollbar1, FALSE, FALSE, 0); gtk_box_pack_start(GTK_BOX(box), hscrollbar2, FALSE, FALSE, 0); gtk_box_pack_start(GTK_BOX(box), hscrollbar3, FALSE, FALSE, 0); gtk_box_pack_start(GTK_BOX(box2), box, FALSE, FALSE, 0); gtk_box_pack_start(GTK_BOX(box2), button_quit, FALSE, FALSE, 20); gtk_container_add(GTK_CONTAINER(fenster),box2); /*Zeigs uns.....*/ gtk_widget_show_all(fenster); gtk_main(); return 0; } |
Und so könnte es aussehen:
