Return an error code when refreshing the entry from the user's input

Browse Source 
2009-01-22  Federico Mena Quintero  <federico@novell.com>

	Return an error code when refreshing the entry from the user's
	input.  We use this in the completion code to know when completion
	can't happen due to (for example) having a non-local URI in a file
	chooser that is local_only=TRUE.

	Also, we start maintaining an invariant that
	chooser_entry->current_folder_file != NULL implies that:

		* what the user entered is valid

		* we are loading that folder (chooser_entry->load_folder_cancellable != NULL)

		* or we are done loading that folder, or we have a handle
		to it at least (chooser_entry->current_folder != NULL)

	The invariant also says that all of the above are NULL (and
	chooser_entry->current_folder_file == NULL) implies that the user
	typed something invalid.  This makes
	_gtk_file_chooser_entry_get_current_folder() not able to return
	an invalid folder.

	* gtk/gtkfilechooserentry.c (RefreshStatus): New enum.
	(refresh_current_folder_and_file_part): Return a RefreshStatus.
	We filter out incomplete hostnames here (typing
	"sftp://incompl[tab]" will error out), as well as completely
	unparsable input.

Return an error code when refreshing the entry from the user's
input. We use this in the completion code to know when completion
can't happen due to (for example) having a non-local URI in a file
chooser that is local_only=TRUE.
Also, we start maintaining an invariant that
chooser_entry->current_folder_file != NULL implies that:
* what the user entered is valid
* we are loading that folder (chooser_entry->load_folder_cancellable != NULL)
* or we are done loading that folder, or we have a handle
to it at least (chooser_entry->current_folder != NULL)
The invariant also says that all of the above are NULL (and
chooser_entry->current_folder_file == NULL) implies that the user
typed something invalid. This makes
_gtk_file_chooser_entry_get_current_folder() not able to return
an invalid folder.
* gtk/gtkfilechooserentry.c (RefreshStatus): New enum.
(refresh_current_folder_and_file_part): Return a RefreshStatus.
We filter out incomplete hostnames here (typing
"sftp://incompl[tab]" will error out), as well as completely
unparsable input.
