[Bluez-devel] [PATCH] add device selector widget

[Bastien Nocera]

[-- Attachment #1: Type: text/plain, Size: 558 bytes --]

It's a first draft of the device selector widget, which I'd like to use
in the applet for gnome-vfs obexftp browsing, and in the wizard. Tadas
can probably use it for the obex sending program as well.

The test program shows how to use it. The API is dead simple.

I also want to add a "Search" button, to restart a discovery, and combo
boxes at the top of it to filter the type/class of device (known,
recently used, recently discovered, and printer/phone/etc.).

Big patch, but not really any other way to do it...

I really do like it and it is a good idea. However we need to change
this a little bit. What we need is multiple things:

BluetoothAdapterChooserWidget

This widget should make it possible to choose an adapter. It can be
either a combo box or a tree view depending on some property.

BluetoothAdapterChooserDialog

Uses the BluetoothAdapterChooserWidget and creates a dialog around.

BluetoothDeviceChooserWidget

Will present devices in range. Has a scan button and other possible
things to tweak it. And actually we should include maybe a widget to
choose the adapter if multiple are available and a property says that is
what we want.

BluetoothDeviceChooserDialog

Use the BluetoothDeviceWidget in a dialog and make it useful for simple
applications.

Mainly all of these four should be modeled along with the GtkFileChooser
stuff and work kinda similar.

Also having some kind of BluetoothDeviceButton that launches a dialog if
needed would be nice.

To shorten the widget names. We might better use _not_ the "Chooser"
word since it looks like Gtk compat stuff because the other name was
already taken by an older widget.

So BluetoothDeviceButton, BluetoothDeviceSelection and
BluetoothDeviceSelectionDialog might be appropriate. What do you think?

Regards

Marcel

In which cases would this be used?

Again, which use cases? Also, why would we need a dialogue (see below
for the reasoning).

That sounds fair, I already wanted the user to be able to show/hide some
of the filter drop-downs, which could/would include the types of devices
as mentioned, as well as the adapter on which to work, although I can't
think of many cases where we would want to show anything but the default
adapter.

I think it's a bit too much work trying to cater for all the uses one
could have of a dialogue, and the amount of code isn't that great to
create the widget ourselves (see example in the test selector, or the
browse device item).

I think a good selector widget that can be inserted in a dialogue would
be better.

> Also having some kind of BluetoothDeviceButton that launches a dialog if

I have a widget like that in gnome-phone-manager, see the prefs
screenshot:
http://live.gnome.org/PhoneManager

It uses libbtctl and gnome-bluetooth widgets right now, but could be
ported easily.

fair enough.

I'm not sure about the dialogue widgets, as I said, but the button and
the chooser widget would be very useful. Not convinced about the adapter
selector either though.

if we need a dialog for the button anyway, we can even provide it as a
widget. Shouldn't be that much work, right? However we can fix the
dialog part later on. The widget itself has to come first anyway.

The device selection widget is more important than an adapter selection
widget, but I see the need for it since it wraps around D-Bus and allows
us not to worry about the details. However there are use cases for the
adapter selection. I have at least one when it comes to the Bluetooth
Analyzer application and its planned live import support. And on the
other hand we have that information inside the model anyway. Only need
to export them into a combo box or tree view.

It's just that the amount of code needed to customise the dialogue for
the need of the app (as in "Connect" button, title, selecting which
drop-downs to show) would be really close to creating a new dialogue.

I expect most applications to use the button selection widget anyway,
and for things like the wizard to use the treeview.

Ha. Yes, does have its uses. I can certainly hack on something like
that.

Here's an updated patch to common/, with the new widget name. I added
the bluetooth- to the filenames, as it's the GNOME way to show the whole
namespace in the header filename.

I think we'll need some changes to the client for when there's no
default adapter (ie. no adapter) and we show the widget, then plug in an
adapter. Any ideas how you would want that implemented?

Cheers

If the adapter gets removed we should make the widget insensitive. For
me that looks like the only sane way to do it. We can send a signal to
inform the user and then they can do whatever they think is right.
However any selection itself becomes invalid at that point.

Regards

Marcel
