GTK实现旋转加载动画

gtk_spinner的使用

#include <gtk/gtk.h>

GtkWidget *window = NULL;
GtkWidget *spinner = NULL;

static void
on_play_clicked (GtkButton *button, gpointer user_data)
{
    
  gtk_spinner_start (GTK_SPINNER (spinner));
}

static void
on_stop_clicked (GtkButton *button, gpointer user_data)
{
    
  gtk_spinner_stop (GTK_SPINNER (spinner));
}
int main() {
    
	GtkWidget *vbox;
	GtkWidget *hbox;
	GtkWidget *button;
	gtk_init(NULL, NULL);
	window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
	gtk_window_set_default_size(GTK_WINDOW(window), 200, 300);

	vbox = gtk_vbox_new (FALSE, 5);
	gtk_container_add (GTK_CONTAINER (window), vbox);
	gtk_container_set_border_width (GTK_CONTAINER (vbox), 5);
	spinner = gtk_spinner_new ();
	gtk_container_add (GTK_CONTAINER (vbox), spinner);

	hbox = gtk_hbox_new (FALSE, 5);
	button = gtk_button_new_from_stock (GTK_STOCK_MEDIA_PLAY);
	g_signal_connect (G_OBJECT (button), "clicked",G_CALLBACK (on_play_clicked), spinner);
	gtk_container_add (GTK_CONTAINER (hbox), button);
	button = gtk_button_new_from_stock (GTK_STOCK_MEDIA_STOP);
	g_signal_connect (G_OBJECT (button), "clicked",G_CALLBACK (on_stop_clicked), spinner);
	gtk_container_add (GTK_CONTAINER (hbox), button);
	gtk_box_pack_start (GTK_BOX (vbox), hbox, TRUE, TRUE, 0);

	gtk_widget_show_all(window);
	g_signal_connect(G_OBJECT(window),"destroy",G_CALLBACK(gtk_main_quit),NULL);
	gtk_main();
	return 0;
}

结果
