I use GtkAboutDialog and everything works fine except the close button of this widget. All other buttons works fine, I don't know how but all buttons have default callbacks and they create and destroy the windows.
But the "Close" button of GtkAboutDialog widget does not work. I can not even see it's widget. So, can I access it?
I have a look in the callbacks.c file and there is just the GtkAboutDialog widget class and no any child widgets.
So, how to close the window? I can not make callback because there is no child widgets...... I do not see them in the source file.

Can you post your source? Typically it's handle using a call to gtk_dialog_run()

Here you are the source code extracted from interface.c
I did not make any callbacks so the other source code is useless here.The interesting thing is that all other buttons work fine but only this "close" button does not work.

GtkWidget*
create_aboutdialog (void)
{
GtkWidget *aboutdialog;
const gchar *authors[] = {
"Marcel M. Weber",
"Svetoslav P. Chukov",
"Testing: Gunter Ohmert",
NULL
};
/* TRANSLATORS: Replace this string with your names, one name per line. */
gchar *translators = _("translator-credits");

aboutdialog = gtk_about_dialog_new ();
gtk_about_dialog_set_version (GTK_ABOUT_DIALOG (aboutdialog), VERSION);
gtk_about_dialog_set_name (GTK_ABOUT_DIALOG (aboutdialog), _("GliBench"));
gtk_about_dialog_set_copyright (GTK_ABOUT_DIALOG (aboutdialog), _("Copyright (C) 2007\nMarcel M. Weber <apw@rossby.metr.ou.edu>\n"));

Can you paste the code that shows the dialog? The callback for the Help->About menu activate?

hydra · Familiar Face Joined: 23 Jan 2007 Posts: 35

Sure. This is the code.

Code: (Plaintext)
1 2 3 4 5 6 7 8 9	void on_about_show (GtkMenuItem menuitem, gpointer user_data) { GtkWidget about_dlg; about_dlg = create_aboutdialog (); gtk_widget_show ( about_dlg ); }

You can also access the close button in you need to since the GtkAboutDialog is derived from GtkDialog. The GtkDialog struct has the action_area member (about_dlg->action_area) which is a GtkHButton box which contains the close button as one of it's children.

However, an easier way to show an about dialog is by using gtk_dialog_run() as shown below:

Code: (Plaintext)
1 2 3 4	GtkWidget * about_dlg; about_dlg = create_aboutdialog (); gtk_dialog_run (GTK_DIALOG (about_dlg )); gtk_widget_destroy (about_dlg);

Thank you very much!
I very appreciate your help and consider to buy the GTK+ book of openldev because the main gtk documentation miss all these small but important details.
