Re: Associating with an entry in a GtkListStore

[Harring Figueiredo <harringf yahoo com>]

 There is a way to associate the data with the model.

 You could use your model like this.

 gtk_list_store_new( NUM_ENTRIES, G_TYPE_STRING, G_TYPE_POINTER)

Where the TYPE_STRING holds the description and the POINTER holds the binary
data.

 That way when you want to associate them, you sjut poull them with 
model_get(..) fuction together.

 The key point here is that the treeview DOES NOT have to have the same number
of columns as the model.


  Hope this helps.
