panel_applet_get_size() lies

First off, I apologise if, this being a GNOME API and not strictly GTK API question, it doesn't belong here, but I couldn't see an equivalent mailing list, and the GNOME list I'm on & tried is more for users than programmers. I have an issue with panel_applet_get_size(); it lies! It r

GtkEntryCompletion with a huge amount of items

Hello, I want to make a dictionary with posibility of completion like it is in GtkEntry Completion. But the dictionary has more items than is possible to fit into GtkEntry Completion, so I'm looking for the same appearance like GtkEntryCompletion has, but I want to make completion by myself.

Re: GtkEntryCompletion with a huge amount of items

propagating errors w.r.t. quark/domain visibility

Is it considered bad form to g_propagate_error() a custom error back to a caller, when the error domain, enum and quark definitions are not visible to the caller? Example: --bar.h-- (an internal module, not seen by the caller) typedef enum { BAR_ERROR_THIS, BAR_ERROR_THAT } BarError;
