Good evening, I remain hopeful I could get some help with the posting at history. First time I didn't get any takers :-). Does anyone have any [germane] thoughts to throw my way?
I appreciate any help folks can offer. Thank you, Regards, James -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of James D. Watson Sent: Sunday, April 14, 2002 1:33 PM To: [EMAIL PROTECTED] Subject: Q: finely tuned drag-n-drop Good morning, GTK+-2.0 documentation for GtkTreeView::gtk_tree_view_set_reorderable reads "This function does not give you any degree of control over the order -- any reorderering is allowed. If more control is needed, you should probably handle drag and drop manually." That's what I'm trying to do :-) I'm trying to limit the order in which a user can place my GtkTreeView rows. My GtkTreeModel has "above" and "below" gint columns for which adjoining rows must match. e.g., rowname above below row_a 15 20 row_b 20 20 row_c 20 15 Note that: row_a's "below" must match row_b's "above" row_b's "below" must match row_c's "above" I want to support reordering such that someone *could* o move row_c on top of row_a (because then row_c's "below" would match row_a's "above") but could *not* o move row_a below row_b (because even though row_c's "above" would match row_a's "below", row_b's "below" would not match row_a's "above"). If I tie in to the "drag_drop" signal, I can do: GtkTreeSelection *sel = gtk_tree_view_get_selection(GTK_TREE_VIEW(widget)); gtk_tree_model_get(model, &iter, ABOVE_COLUMN, &above, BELOW_COLUMN, &below, -1); which tells me the above/below for the current selection which is the one being moved. (My selection type is "SINGLE".) But this doesn't seem to be the right signal to tie in to since I want to find out *where* in the GtkTreeView (i.e., what row) the current selection is trying to be dropped, whereupon I could then make an "accept" or "reject" decision. I'd certainly appreciate some tips.
