This reverts commit15e26a6a9a, whose purpose was to tweak the Qt configuration to force TLS, i.e., to disable SSLv3, in Qt versions >= 5.5. However, the default behavior of Qt >= 5.4 is to disable SSLv3 anyway [1], so the configuration tweak is redundant. With Qt 5.11.2, the configuration tweak is not only redundant but in fact provokes a deadlock (#14359) due to Qt 5.11.2 being incompatible with OpenSSL 1.1.1 [2]. Since the deadlock occurs at the early startup stage of bitcoin-qt, it renders bitcoin-qt entirely non-functional when compiled against OpenSSL 1.1.1 and Qt 5.11.2 (and possible future combinations of OpenSSL and Qt versions). This commit fixes #14359 by removing the redundant code.

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 and BIP70 (see https://github.com/bitcoin/bitcoin/pull/11622) 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.

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:
- Make sure you installed everything through Homebrew mentioned in the macOS build instructions
- Use
./configurewith the--enable-debugflag - In Qt Creator do "New Project" -> Import Project -> Import Existing Project
- Enter "bitcoin-qt" as project name, enter src/qt as location
- Leave the file selection as it is
- Confirm the "summary page"
- In the "Projects" tab select "Manage Kits..."
- Select the default "Desktop" kit and select "Clang (x86 64bit in /usr/bin)" as compiler
- Select LLDB as debugger (you might need to set the path to your installation)
- 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)
