如何在GTK中进行无限循环

#include <gtk/gtk.h>

// 回调函数，用于处理窗口关闭事件
static gboolean on_window_closed(GtkWidget *widget, GdkEvent *event, gpointer user_data)
{
    gtk_main_quit(); // 终止主循环
    return TRUE;
}

int main(int argc, char *argv[])
{
    gtk_init(&argc, &argv);

    // 创建窗口
    GtkWidget *window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
    g_signal_connect(window, "delete-event", G_CALLBACK(on_window_closed), NULL);

    // 显示窗口
    gtk_widget_show_all(window);

    // 启动主循环
    gtk_main();

    return 0;
}
