Graphics programming • Re: help me set up Geany to work with the GTK+ library in C++

Code:

#include <gtk/gtk.h>// Callback function for button click eventstatic void on_button_clicked(GtkWidget *widget, gpointer data) {    gtk_button_set_label(GTK_BUTTON(widget), "Button Clicked!");}int main(int argc, char *argv[]) {    GtkWidget *window;    GtkWidget *button;    // Initialize GTK    gtk_init(&argc, &argv);    // Create a new window    window = gtk_window_new(GTK_WINDOW_TOPLEVEL);    gtk_window_set_title(GTK_WINDOW(window), "Simple Gtk+3 Window");    gtk_window_set_default_size(GTK_WINDOW(window), 400, 200);    // Connect the window's destroy event to the main loop exit function    g_signal_connect(window, "destroy", G_CALLBACK(gtk_main_quit), NULL);    // Create a new button    button = gtk_button_new_with_label("Click Me!");    // Connect the button's clicked event to the callback function    g_signal_connect(button, "clicked", G_CALLBACK(on_button_clicked), NULL);    // Add the button to the window    gtk_container_add(GTK_CONTAINER(window), button);    // Show all widgets within the window    gtk_widget_show_all(window);    // Start the main loop    gtk_main();    return 0;}
