Hi there, I've got a problem with drawing a line and a button in a window at the same time. When I run the following program I can see the line only and no button... Can anybody advise me how display those two items simultaneously? My intention is to have a number of buttons displayed in the window (those buttons are to represent the nodes in a graph) and a mumber of lines among them (those lines are to represent the links/connections between the selected pairs of nodes). I've tried many diffrent things and I'm not sure if this is feasible with GTK... Thanks, Michal #include <gtk/gtk.h> gint expose (GtkWidget *widget, GdkEventExpose *event, gpointer data) { gdk_draw_line (widget->window, widget->style->black_gc, 100, 50, 50, 100); } int main (int argc, char **argv) { GtkWidget *window; GtkWidget *button; gtk_init (&argc, &argv); window = gtk_window_new (GTK_WINDOW_TOPLEVEL); button = gtk_button_new_with_label("Button"); gtk_container_add(GTK_CONTAINER(window), button); gtk_signal_connect (GTK_OBJECT (window), "expose_event", GTK_SIGNAL_FUNC (expose), NULL); gtk_widget_show(button); gtk_widget_show (window); gtk_main (); return 0; } |
