Storing and retrieving events

[Russell Shaw <rjshaw iprimus com au>]

Hi,
I have a popup menu that works by calling this function:

gboolean
button_press_cb(GtkWidget *widget, GdkEventButton *event, gpointer user_data)
{
    gtk_menu_popup(GTK_MENU(popup),NULL,NULL,NULL,NULL,event->button,event->time);
}

This causes the popup menu "activate" callback function to be called
properly when invoked.


However, now i need to get the same popup invoked from button_click_cb()
that is called by using g_timeout_add() in button_press_cb().

The popup menu works ok, but the callback function for the popup menu
"activate" signal is never called.


typedef struct {
    GdkEventButton *event;
    GtkWidget *widget;
} button_msg_t;

button_msg_t button_msg;


// this function is called first to set a time for button_click_cb() to be called

gboolean
button_press_cb(GtkWidget *widget, GdkEventButton *event, gpointer user_data)
{
    button_msg.event=(GdkEventButton*)gdk_event_copy((GdkEvent*)event);
    button_msg.widget=gtk_widget_ref(widget);

    GdkDisplay *disp=gtk_widget_get_display(widget);
    click_id=g_timeout_add(disp->double_click_time,button_click_cb,(gpointer)(&button_msg));
    return TRUE;
}


gboolean button_click_cb(gpointer data)
{
//  contents of "event" and "widget" have been verified

    GdkEventButton *event=((button_msg_t*)data)->event;
    GtkWidget *widget=((button_msg_t*)data)->widget;

    gtk_menu_popup(GTK_MENU(popup),NULL,NULL,NULL,NULL,event->button,event->time);

    gdk_event_free((GdkEvent*)event);
    gtk_widget_unref(widget);
...
    return FALSE;
}
