Pull request description:

  Remove `fees.h`, `errors.h`, and `spanparsing.h` from the util library. Specifically:

  - Move `Split` functions from `util/spanparsing.h` to `util/string.h`, using `util` namespace for clarity.
  - Move remaining spanparsing functions to `script/parsing.h` since they are used for descriptor and miniscript parsing.
  - Combine `util/fees.h` and `util/errors.h` into `common/messages.h` so there is a place for simple functions that generate user messages to live, and these functions are not part of the util library.

  Motivation for this change is that the util library is a dependency of the kernel, and we should remove functionality from util that shouldn't be called by kernel code or kernel applications. These changes should also improve code organization and make functions easier to discover. Some of these same moves are (or were) part of #28690, but did not help with code organization, or made it worse, so it is better to move them and clean them up in the same PR so code only has to change one time.

This directory contains the source code for the Bitcoin Core graphical user interface (GUI). It uses the Qt cross-platform framework.

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

Compile and run

See build instructions: Unix, macOS, Windows, FreeBSD, NetBSD, OpenBSD

When following your systems build instructions, make sure to install the Qt dependencies.

To run:

./src/qt/bitcoin-qt

Files and Directories

forms/

  • A directory that contains Designer UI files. These files specify the characteristics of form elements in XML. Qt UI files can be edited with Qt Creator or using any text editor.

locale/

  • Contains translations. They are periodically updated and an effort is made to support as many languages as possible. The process of contributing translations is described in doc/translation_process.md.

res/

  • Contains graphical resources used to enhance the UI experience.

test/

  • Functional tests used to ensure proper functionality of the GUI. Significant changes to the GUI code normally require new or updated 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)

  • (Deprecated) 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 an IDE

Qt Creator is a powerful tool which packages a UI designer tool (Qt Designer) and a C++ IDE into one application. This is especially useful if you want to change the UI layout.

Download Qt Creator

On Unix and macOS, Qt Creator can be installed through your package manager. Alternatively, you can download a binary from the Qt Website.

Note: If installing from a binary grabbed from the Qt Website: During the installation process, uncheck everything except for Qt Creator.

macOS
brew install qt-creator
Ubuntu & Debian
sudo apt-get install qtcreator

Setup Qt Creator

  1. Make sure you've installed all dependencies specified in your systems build instructions
  2. Follow the compile instructions for your system, run ./configure with the --enable-debug flag
  3. Start Qt Creator. At the start page, do: New -> Import Project -> Import Existing Project
  4. Enter bitcoin-qt as the Project Name and enter the absolute path to src/qt as Location
  5. Check over the file selection, you may need to select the forms directory (necessary if you intend to edit *.ui files)
  6. Confirm the Summary page
  7. In the Projects tab, select Manage Kits...

macOS

  • Under Kits: select the default "Desktop" kit
  • Under Compilers: select "Clang (x86 64bit in /usr/bin)"
  • Under Debuggers: select "LLDB" as debugger (you might need to set the path to your LLDB installation)

Ubuntu & Debian

Note: Some of these options may already be set

  • Under Kits: select the default "Desktop" kit
  • Under Compilers: select "GCC (x86 64bit in /usr/bin)"
  • Under Debuggers: select "GDB" as debugger
  1. While in the Projects tab, ensure that you have the bitcoin-qt executable specified under Run
  • If the executable is not specified: click "Choose...", navigate to src/qt, and select bitcoin-qt
  1. You're all set! Start developing, building, and debugging the Bitcoin Core GUI
