使用GTK查找工作区大小(屏幕大小减去任务栏)

#include <gtk/gtk.h>

int main(int argc, char *argv[]) {
    GtkWidget *window;

    gtk_init(&argc, &argv);

    window = gtk_window_new(GTK_WINDOW_TOPLEVEL);

    g_signal_connect(G_OBJECT(window), "destroy", G_CALLBACK(gtk_main_quit), NULL);

    gtk_widget_show_all(window);

    gint width, height;
    gdk_screen_get_monitor_geometry(gdk_screen_get_default(), 0, NULL, &width, &height);

    g_print("工作区宽度: %d\n", width);
    g_print("工作区高度: %d\n", height);

    gtk_main();

    return 0;
}
