如何使用C短时间显示GTK工具提示？

#include <gtk/gtk.h>

gtk_init(&argc, &argv);

GtkWidget *window;
window = gtk_window_new(GTK_WINDOW_TOPLEVEL);

GtkWidget *label;
label = gtk_label_new("提示信息");

GtkTooltips *tooltips;
tooltips = gtk_tooltips_new();
gtk_tooltips_set_tip(tooltips, window, "提示信息", NULL);

gtk_widget_set_tooltip_window(window, GTK_WIDGET(tooltips));

gtk_widget_show_all(window);
gtk_tooltips_enable(tooltips);

gtk_main();

#include <gtk/gtk.h>

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

    GtkWidget *window;
    window = gtk_window_new(GTK_WINDOW_TOPLEVEL);

    GtkWidget *label;
    label = gtk_label_new("提示信息");

    GtkTooltips *tooltips;
    tooltips = gtk_tooltips_new();
    gtk_tooltips_set_tip(tooltips, window, "提示信息", NULL);

    gtk_widget_set_tooltip_window(window, GTK_WIDGET(tooltips));

    gtk_widget_show_all(window);
    gtk_tooltips_enable(tooltips);

    gtk_main();

    return 0;
}
