[Glade-users] Variables switched in the GtkDialog Response Callback

[diogofsr at gmail.com (Diogo Ramos)]

I was playing during some time with the gtkdialog response callback and I
had noticed some strange behaviors.
Them finale, I figured it out.
The protoptipe of the callback in the gtk manual is:
void                user_function          (GtkDialog *dialog,
                                                        gint       arg1,
                                                        gpointer
user_data)

But, when I set glade to pass one widget from user_data, the protoptipe is
actually switched.
What I mean is that *dialog becomes user_data and user_data becomes *dialog.
So, if I want to use the widget which I passed thought the glade_xml, I  use
*dialog, not user_data.
I made a little test file:

main.c
/*************************/
#include <gtk/gtk.h>
#include <stdlib.h>
#include <glade/glade.h>

void
resposta( GtkDialog *dialog, gint arg1, gpointer data )
{
    switch( arg1 )
    {
    case GTK_RESPONSE_OK:
    {
    const gchar *str = NULL;
    str = gtk_entry_get_text( GTK_ENTRY(dialog));

    printf("Entry:%s\n", str );
    break;
    }
    case GTK_RESPONSE_CANCEL:
    {
    gtk_main_quit();
    }
    }
}

int main( int argc, char *argv[] )
{
    GladeXML *xmlTree;
    GtkWidget *dialog1;
    gtk_init(&argc, &argv);

    xmlTree = glade_xml_new ("interface.glade", NULL, NULL);
    dialog1 = glade_xml_get_widget(xmlTree, "dialog1");
    glade_xml_signal_autoconnect(xmlTree);
    g_object_unref( xmlTree );
    gtk_widget_show(dialog1);

    gtk_main();

    return EXIT_SUCCESS;
}

Is this behavior desired or is it a bug?
Seems to be a bug, but what I know? ;-)
