Hey I am a newbie to GTK+ 2 and Glade 2. I have been playing around
with GTK and I understand the concept behind signals and events. My
problem arised when I decided to use Glade 2 and wanted to connect a
'clicked' signal for a 'modal' 'dialog' window 'button'. When
connecting any signal handler to a signal I know you can pass extra data
to the handler if you wish. In Glade 2 when connecting a signal you can
also set the extra data and it casts it as a GTK_OBJECT. In my
callbacks.c file my handler is there: code snippet
void on_okLoginButton_clicked(GtkButton *button, gpointer user_data)
{
gtk_widget_destroy( GTK_WIDGET(user_data) );
}
My call to destroy the dialog window only destroys the button. However
when I change the widget to destroy to: GTK_WIDGET(button), everything
works fine. Seems to me something is reversed. Also I went into my
interface.c file and found the actual code to call the handler and found
this:
g_signal_connect_swapped((gpointer) okLoginButton, "clicked",
G_CALLBACK (on_okLoginButton_clicked),
GTK_OBJECT (loginDialog) );
Where loginDialog is my dialog window I want to close.
If you actually read the whole thing and are willing to help a newbie
out I would greatly appreciate any explanation of this if anyone has ran
into this problem.
Maybe you need: g_signal_connect((gpointer) okLoginButton, "clicked",
G_CALLBACK (on_okLoginButton_clicked),
GTK_OBJECT (loginDialog) );
