Also put back set_layout. This is causing two things:
a) on MacOSX the next / cancel buttons vanish if in one position
b) on all O/Ses the Next button is not the default
We're obviously abusing StackedLayout in an unintended way.
This code is identical to before, but for some reason the positioning
of this affects whether Next is the default action or not!
And it didn't have that effect with the old install wizard. Odd.
Benefits of this rewrite include:
- support of disconnecting / reconnecting a device without having
to close the wallet, even in a different USB socket
- support of multiple keepkey / trezor devices, both during wallet
creation and general use
- wallet is watching-only dynamically according to whether the
associated device is currently plugged in or not
Break out the workflow logic of the install wizard
into a base class. This means reimplementing with
full support in a new GUI is now easy; you just provide
ways to request passwords, show messages etc. The API
is fully documented in the base class.
There are a couple of minor outstanding issues, including that
the old messages shown when recovering a wallet are missing.
I will come back to that. Ledger wallet might be broken.
Other improvements:
The install wizard code is now easy to follow and understand.
Hardware wallets can now be restored without any need for their
accompanying libraries.
Various bits of trustedcoin were broken and have been fixed.
Many plugin hooks can be removed. I have only started on this.
As per BIP44, 20 addresses are checked for transactions, not just the
first one.
Show the last account only if used or named.
If all accounts are used, prompt for password to create new one.
Fixes#1128
Fixes#1585
Warn user if watching-only.
Introduce new helper class WindowModalDialog and use it in a couple
of places. This is better than process-modal dialogs for our
multi-window daemon setup.
This should speed up synchronization / restoration of large wallets.
Wallets are written only when they switch to up_to_date state, or
when stop_threads() is called when closing the daemon, or when
a command line command finishes.
