Merge #16963: wallet: Fix unique_ptr usage in boost::signals2
6d6a7a8403ae923f189812edebdd95761de0e7f2 gui: Fix duplicate wallet showing up (João Barbosa)
81ea66c30e2953dee24d5b127c28daa0d9452a28 Drop signal CClientUIInterface::LoadWallet (Russell Yanofsky)

Pull request description:

  This PR includes 2 fixes:
   - prevent GUI LoadWallet handlers from crashing on startup when multiple handlers are attached, because the first handler takes ownership of the wallet unique pointer. Now every handler will receive its own unique pointer;

   - prevent showing a wallet twice in the GUI on startup due to a race with `loadwallet`.

  Fixes #16937

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

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)
