I am writing a dialog that receives an integer value on creation and then passes that same value to a on_button_clicked callback. Ideas? You have at least three options: (i) Set the data as the user_data when you connect to the signal; it will get passed as a parameter to the callback - though only to that callback. (ii) If the data is shared between multiple callbacks, you can attach it as generic data to the dialog. Under GTK 2.* , look at g_object_set_data and g_object_get_data; under GTK 1.*, look at gtk_object_set_data, gtk_object_get_data (IIRC). This is good if you've got data shared between several callbacks. (iii) Create a custom dialog subclass. Do this if you've got lots of data, with complicated semantics. But it can be pain. I tend to go for method (ii) Good luck! Dave Malcolm
