QuizEditor

A desktop quiz editor with drag-and-drop reordering for both questions and answers, and XML import/export. Originally written for Qt 4.8 and ported to Qt 6 (CMake, C++17).

Features

• Multiple-choice questions with any number of answers per question.
• Drag-and-drop to reorder questions and to reorder answer options within a question. Drops are scoped per container — answers can't be accidentally moved to a different question.
• XML save/load with a simple, human-readable schema (see example.xml).
• Mark-as-correct checkboxes for any number of answers per question.
• Question sections (chapter numbers) for grouping in the output XML.
• Unsaved-changes guard on New / Open / Close.

Requirements

• Qt 6.2 or newer (modules: Core, Gui, Widgets, Xml).
• CMake 3.19 or newer.
• A C++17 compiler:
  • Windows: MSVC 2019/2022 (bundled with Qt 6) or MinGW 8.1+.
  • Linux: GCC 9+ or Clang 10+.
  • macOS: Apple Clang 12+.

Build (Windows + PowerShell)

The repository ships with a CMake project. A copy-paste build:

# 1) Point CMake at your Qt 6 install and put Qt + MinGW on PATH.
$env:CMAKE_PREFIX_PATH = "C:\Qt\6.11.1\mingw_64"
$env:Path = "C:\Qt\6.11.1\mingw_64\bin;C:\Qt\Tools\mingw1310_64\bin;C:\Program Files\CMake\bin;$env:Path"

# 2) Configure (Ninja is the fastest generator on Windows).
& "C:\Qt\Tools\CMake_64\bin\cmake.exe" -S . -B build -G Ninja `
    -DCMAKE_BUILD_TYPE=Release `
    -DCMAKE_MAKE_PROGRAM="C:\Qt\Tools\Ninja\ninja.exe"

# 3) Build.
& "C:\Qt\Tools\CMake_64\bin\cmake.exe" --build build

# 4) Run.
.\build\QuizEditor.exe

If Windows can't find Qt6Core.dll and friends, either re-launch from a shell where C:\Qt\6.11.1\mingw_64\bin is on PATH, or run:

& "C:\Qt\6.11.1\mingw_64\bin\windeployqt.exe" --release build\QuizEditor.exe

windeployqt copies the runtime DLLs and platform plugins next to the executable, producing a folder you can zip and ship to other Windows machines.

Build (Linux / macOS)

export CMAKE_PREFIX_PATH=/opt/Qt/6.7.0/gcc_64     # or your Qt 6 prefix
cmake -S . -B build -DCMAKE_BUILD_TYPE=Release
cmake --build build
./build/QuizEditor

Build (Qt Creator)

1. File → Open File or Project… and pick CMakeLists.txt.
2. Qt Creator detects the kit and CMAKE_PREFIX_PATH automatically.
3. Build → Run.

XML format

saveToFile writes a simple UTF-8 document:

<?xml version="1.0" encoding="UTF-8"?>
<controls>
  <ukmControl>
    <qwestions>
      <qwestion title="…" id="c_1" chapter="…">
        <answers orderRight="0,2" orderUser="-1">
          <answer>…</answer>
          <answer>…</answer>
        </answers>
      </qwestion>
      …
    </qwestions>
    <doing>Нет</doing>
    <id>1</id>
  </ukmControl>
</controls>

• orderRight — comma-separated zero-based indexes of the correct answers.
• chapter is normalized to h_<name> if it isn't already prefixed.
• A sample file is in example.xml.

parent = 0	parent = nullptr
Implicit <QFile> / <QMessageBox>	explicit #include
qmake (.pro)	CMake (CMakeLists.txt) + AUTOMOC/AUTORCC/AUTOUIC
