Hi, All,
Sorry for late response.
I'm ready to give you a C code as I mentioned.
Below is a sample code.
As you know, please compile as follows.
$ gcc -Wall -o helloworld `pkg-config --cflags --libs gtk+-2.0` helloworld.c
I'm enough at present since I found this is well-known bug
and has been registered at bugzilla.
However, what I want to know next is how I find a workaround
about it.
Any hint from you would be highly appreciated!
===== Cut here and Paste as helloworld.c =====
#include <gtk/gtk.h>
GtkWidget* button;
gint timertag = -1;
static gboolean timer_expired(gpointer val)
{
gtk_timeout_remove(timertag);
timertag=-1;
gtk_widget_set_sensitive (button, TRUE);
g_print("timer timeout.\n\n");
return FALSE;
}
static void hello( GtkWidget *widget,
gpointer data )
{
g_print("Enter callback\n");
gtk_widget_set_sensitive (button, FALSE);
// g_print ("Hello World\n");
timertag = g_timeout_add(3000/*msec*/, timer_expired, NULL);
g_print("Exit callback\n");
}
static gboolean delete_event( GtkWidget *widget,
GdkEvent *event,
gpointer data )
{
/* If you return FALSE in the "delete_event" signal handler,
* GTK will emit the "destroy" signal. Returning TRUE means
* you don't want the window to be destroyed.
* This is useful for popping up 'are you sure you want to quit?'
* type dialogs. */
g_print ("delete event occurred\n");
/* Change TRUE to FALSE and the main window will be destroyed with
* a "delete_event". */
// return TRUE;
return FALSE;

/* Another callback */

gpointer data )
{
gtk_main_quit ();

/* add a reference tag */
gtk_object_set_data (GTK_OBJECT (window), "window", window);
/* When the window is given the "delete_event" signal (this is given
* by the window manager, usually by the "close" option, or on the
* titlebar), we ask it to call the delete_event () function
* as defined above. The data passed to the callback
* function is NULL and is ignored in the callback function. */
g_signal_connect (G_OBJECT (window), "delete_event",
G_CALLBACK (delete_event), NULL);
/* Here we connect the "destroy" event to a signal handler.
* This event occurs when we call gtk_widget_destroy() on the window,
* or if we return FALSE in the "delete_event" callback. */
g_signal_connect (G_OBJECT (window), "destroy",
G_CALLBACK (destroy), NULL);
/* Sets the border width of the window. */
gtk_container_set_border_width (GTK_CONTAINER (window), 10);
/* Creates a new button with the label "Hello World". */

/* add a reference tag */
gtk_object_set_data (GTK_OBJECT (button), "button", button);
/* When the button receives the "clicked" signal, it will call the
* function hello() passing it NULL as its argument. The hello()
* function is defined above. */
g_signal_connect (G_OBJECT (button), "clicked",
G_CALLBACK (hello), NULL);
// /* This will cause the window to be destroyed by calling
// * gtk_widget_destroy(window) when "clicked". Again, the destroy
// * signal could come from here, or the window manager. */
// g_signal_connect_swapped (G_OBJECT (button), "clicked",
// G_CALLBACK (gtk_widget_destroy),
// G_OBJECT (window));
/* This packs the button into the window (a gtk container). */
gtk_container_add (GTK_CONTAINER (window), button);
/* The final step is to display this newly created widget. */
gtk_widget_show (button);
/* and the window */
gtk_widget_show (window);
/* All GTK applications must have a gtk_main(). Control ends here
* and waits for an event to occur (like a key press or
* mouse event). */
gtk_main ();
return 0;
