Pull request description:
Currently, the user interface (noui, gui) has a caption for each message. However, the caption has many issues:
* It is always hard-coded to the empty string.
* This is confusing and tedious when reading or maintaining the code.
* It is redundant, because `noui` will ignore the caption and set the logging prefix (error, warning, info) based on the `style`.
* The gui does prefer to set the title based on the caption, but since it the caption is always empty, the fallback will always be used.
Fix all issues by removing it.

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 is specified in qt_details.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:
./build/bin/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
bitcoinguiand several models likepeertablemodel.
*page.(h/cpp)
- A controller.
:NAMEpage.cppgenerally includes:NAMEmodel.handforms/:NAME.page.uiwith 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.

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
