This returns the text that should be completed on. As this is somewhat
tricky to compute (and in fact one place did it wrong), let's make it a
function.
Now that we don't need to know anymore why insertion failed, we can
simplify the append function quite a lot.
A simple rule now: If we did not insert anything, beep.
Too much special code for no gain.
I did a totally unscientific questionnaire on GNOME IRC (assuming
autocompletion is for advanced users) and nobody even knew what this is.
So I suspect it's useless. Also, it's positioned completely wrong anyway
and nobody noticed so far. Last but not least, I'm trying to imitate
bash here and bash doesn't show feedback.
Use dispatch_properties_changed() instead of GtkEditable to watch for
changes to the to-be-completed text. This is necessary because various
functions in GtkEntry don't use the interface vfuncs and one only
becomes aware of them via notifications. I'm not sure this is intended
behavior, but it's how it works today.
Also, use the same code for triggering in all situations.
What the code does is this: It looks at the part of the text in front of
the cursor (or selection) and completes for it. Once the directory has
been enumerated, inline completion is activated. Note that popping up of
the completion popup is completely handled by GtkEntry.
Instead, pass the text to use to refresh_current_folder_and_file_part().
This also gets rid of the problem introduced earlier that the position
is not properly updated in do_insert_text() and therefor the completion
is wrong.
... from GtkEntryCompletion instead of implementing a poor copy
ourselves. This also makes the file chooser entry behave a lot closer to
normal entries.
This is identical to the display name when not having a path that
changes the folder. Otherwise it will have the full path that was
entered in the entry. Say when from your home dir, you type
"../../usr/li", the full path for "lib" and "lib64" will be
"../../usr/lib" and "../../usr/lib64" respectively. This value isn't
used yet, but will be soon.
The new version does not need to muck with the entry, it just extracts
the required information. It returns a reference to the folder though,
as we extract the information now instead of returning something stored.
Setter functions the way I code it look like this (in order):
1) Figure out if the value changed. If not, exit early.
2) Clear the old value (ie unref stuff, disconnect signals
3) Copy the new value
4) Set up things about the new value
This reorganization does that.
And by doing that, it even reduces the amount of code and the amount of
branches (and with it, nesting) needed.
Instead, fall through to the default handler after closing the
completion. This has the advantage of letting the file chooser entry
capture the tab key properly, so one can't accidentally move out of the
entry by pressing tab while the completion is popped up.
I also suspect it fixes bugs with weird tab keys and shift/ctrl
oddities. But who knows...
