如何使用gtk信号将多个变量作为数据传递

#include <gtk/gtk.h>

void on_button_clicked(GtkWidget *button, gpointer user_data) {
    int *data = (int *)user_data;
    int var1 = data[0];
    int var2 = data[1];

    // 在这里处理变量var1和var2
    g_print("Button clicked: var1=%d, var2=%d\n", var1, var2);
}

int main(int argc, char *argv[]) {
    GtkWidget *window, *button;
    int data[2] = {10, 20};

    gtk_init(&argc, &argv);

    window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
    button = gtk_button_new_with_label("Click me");

    g_signal_connect_data(button, "clicked", G_CALLBACK(on_button_clicked), data, NULL, 0);

    gtk_container_add(GTK_CONTAINER(window), button);
    gtk_widget_show_all(window);

    gtk_main();

    return 0;
}
