Could someone explain the reason for this function
"g_signal_connect_swapped"
I have read the manual here:
http://www.gtk.org/tutorial/x159.html
where it says:
,----
| g_signal_connect_swapped() is the same as g_signal_connect() except that
| the instance on which the signal is emitted and data will be swapped
| when calling the handler. So when using this function to connect
| signals, the callback should be of the form
|
|
| void callback_func( gpointer callback_data,
| ... /* other signal arguments */
| GtkWidget *widget);
|
| where the object is usually a widget.
`----
Could anyone express this a little clearer? I (as a gtk beginner) can
see no reason for it.
