Pull request description:

  Continuation of wallet boxes project.

  Actually makes ScriptPubKeyMan an interface which LegacyScriptPubkeyMan. Moves around functions and things from CWallet into LegacyScriptPubKeyMan so that they are actually separate things without circular dependencies.

  ***

  Introducing the `ScriptPubKeyMan` (short for ScriptPubKeyManager) for managing scriptPubKeys and their associated scripts and keys. This functionality is moved over from `CWallet`. Instead, `CWallet` will have a pointer to a `ScriptPubKeyMan` for every possible address type, internal and external. It will fetch the correct `ScriptPubKeyMan` as necessary. When fetching new addresses, it chooses the `ScriptPubKeyMan` based on address type and whether it is change. For signing, it takes the script and asks each `ScriptPubKeyMan` for whether that `ScriptPubKeyMan` considers that script `IsMine`, whether it has that script, or whether it is able to produce a signature for it. If so, the `ScriptPubKeyMan` will provide a `SigningProvider` to the caller which will use that in order to sign.

  There is currently one `ScriptPubKeyMan` - the `LegacyScriptPubKeyMan`. Each `CWallet` will have only one `LegacyScriptPubKeyMan` with the pointers for all of the address types and change pointing to this `LegacyScriptPubKeyMan`. It is created when the wallet is loaded and all keys and metadata are loaded into it instead of `CWallet`. The `LegacyScriptPubKeyMan` is primarily made up of all of the key and script management that used to be in `CWallet`. For convenience, `CWallet` has a `GetLegacyScriptPubKeyMan` which will return the `LegacyScriptPubKeyMan` or a `nullptr` if it does not have one (not yet implemented, but callers will check for the `nullptr`). For purposes of signing, `LegacyScriptPubKeyMan`'s `GetSigningProvider` will return itself rather than a separate `SigningProvider`. This will be different for future `ScriptPubKeyMan`s.

  The `LegacyScriptPubKeyMan` will also handle the importing and exporting of keys and scripts instead of `CWallet`. As such, a number of RPCs have been limited to work only if a `LegacyScriptPubKeyMan` can be retrieved from the wallet. These RPCs are `sethdseed`, `addmultisigaddress`, `importaddress`, `importprivkey`, `importpubkey`, `importmulti`, `dumpprivkey`, and `dumpwallet`. Other RPCs which relied on the wallet for scripts and keys have been modified in order to take the `SigningProvider` retrieved from the `ScriptPubKeyMan` for a given script.

  Overall, these changes should not effect how everything actually works and the user should experience no difference between having this change and not having it. As such, no functional tests were changed, and the only unit tests changed were those that were directly accessing `CWallet` functions that have been removed.

  This PR is the last step in the [Wallet Structure Changes](https://github.com/bitcoin-core/bitcoin-devwiki/wiki/Wallet-Class-Structure-Changes).

This directory contains the BitcoinQT graphical user interface (GUI). It uses the cross-platform framework Qt.

The current precise version for Qt 5 is specified in qt.mk.

Compile and run

See build instructions (macOS, Windows, Unix, etc).

To run:

./src/qt/bitcoin-qt

Files and directories

forms

Contains Designer UI files. They are created with Qt Creator, but can be edited using any text editor.

locale

Contains translations. They are periodically updated. The process is described here.

res

Resources such as the icon.

test

Tests.

bitcoingui.(h/cpp)

Represents the main window of the Bitcoin UI.

*model.(h/cpp)

The model. When it has a corresponding controller, it generally inherits from QAbstractTableModel. Models that are used by controllers as helpers inherit from other Qt classes like QValidator.

ClientModel is used by the main application bitcoingui and several models like peertablemodel.

*page.(h/cpp)

A controller. :NAMEpage.cpp generally includes :NAMEmodel.h and forms/:NAME.page.ui with a similar :NAME.

*dialog.(h/cpp)

Various dialogs, e.g. to open a URL. Inherit from QDialog.

paymentserver.(h/cpp)

Used to process BIP21 payment URI requests. Also handles URI based application switching (e.g. when following a bitcoin:... link from a browser).

walletview.(h/cpp)

Represents the view to a single wallet.

Other .h/cpp files

  • UI elements like BitcoinAmountField, which inherit from QWidget.
  • bitcoinstrings.cpp: automatically generated
  • bitcoinunits.(h/cpp): BTC / mBTC / etc handling
  • callback.h
  • guiconstants.h: UI colors, app name, etc
  • guiutil.h: several helper functions
  • macdockiconhandler.(h/mm): macOS dock icon handler
  • macnotificationhandler.(h/mm): display notifications in macOS

See CONTRIBUTING.md for general guidelines. Specifically for Qt:

Using Qt Creator as IDE

You can use Qt Creator as an IDE. This is especially useful if you want to change the UI layout.

Download and install the community edition of Qt Creator. Uncheck everything except Qt Creator during the installation process.

Instructions for macOS:

  1. Make sure you installed everything through Homebrew mentioned in the macOS build instructions
  2. Use ./configure with the --enable-debug flag
  3. In Qt Creator do "New Project" -> Import Project -> Import Existing Project
  4. Enter "bitcoin-qt" as project name, enter src/qt as location
  5. Leave the file selection as it is
  6. Confirm the "summary page"
  7. In the "Projects" tab select "Manage Kits..."
  8. Select the default "Desktop" kit and select "Clang (x86 64bit in /usr/bin)" as compiler
  9. Select LLDB as debugger (you might need to set the path to your installation)
  10. Start debugging with Qt Creator (you might need to the executable to "bitcoin-qt" under "Run", which is where you can also add command line arguments)
