*** UNFINISHED, EXPERIMENTAL, PROTOTYPE-QUALITY CODE! ***

• The last version (0.6.0) was built against SFML@698f265 (and is incompatible with most other SFML versions!).
• A successor is being worked on, which will be published if/when sufficiently matured.

sfw::GUI - A fork of "SFML Widgets", a small & simple SFML-based GUI

Original (upstream) author: Alexandre Bodelot alexandre.bodelot@gmail.com

License: MIT License (See the LICENSE file.)

Changes to the original:

• Adapted to the upcoming SFML v3 API
• Richer, more flexible API, new features, improvements, bugfixes
• Default quick-start assets included (and removed the non-free ones)
• Windows build (MSVC & GCC (via w64devkit, so MingW should also work))
• Auto download & setup the latest SFML-master locally (mostly for GitHub workflows)
• Requires some C++23 features (e.g. std::expected)

Main features:

• Moderately sized package with no external dependencies beyond SFML
• Simple, but versatile API
• Visual styling via spritesheets (small image files to customize borders, markers etc.)
• Optional callbacks for widget updates (supporting both []() and [](Widget*) lambda signatures) (Other event handlers can also be overridden via inheritance.)
• Easy layouts: automatically (and dynamically re)positioned/sized widgets
• Translucent wallpapers, tooltips
• No CMake. (Well, since I never got to learn it, I just declare this a feature now. ;) Use e.g. TGUI if you don't feel warm and cozy without CMake.)

Build

• Run build on Windows, or make on Linux, to create the lib + the example/demo/test executables.
• MSVC and GCC (both on Linux and w64devkit/MinGW) are auto-detected. (CLANG support has kinda rotted away by now.)
• The GCC option supports header auto-dependency tracking yet. (No working clean rule currently: delete tmp/build and the lib binaries under lib/)

(See the Makefiles for options.)

Use

0. Integrate (via env. vars, or just copy) the include & lib dirs to your project. (Copy the asset dir, too, if you want to use the stock defaults.)
1. #include "sfw/GUI.hpp".
2. Optionally (but typically) customize the theme: the styling texture image, font, colors etc.
3. Create the top-level GUI manager object, connecting it to your SFML window (like: sfw::GUI myGUI(window);), usually with your custom theme config (sfw::GUI myGUI(window, myConfig);)
4. Add containers (layouts) and widgets with add(sfw::SomeWidget(...)), or if you prefer: add(new sfw::OtherWidget) calls, set their properties (typically with method chaining, like add(new TextBox)->set("hi")->setCallback(...)) etc. Note: widget objects will be managed (e.g. deleted) implicitly.
5. Pass events to the GUI (in your app's event loop): myGUI.process(event);.
6. Draw the GUI (in your frame refresh loop; i.e. the event loop in single-treaded apps): myGUI.render();.
7. Have fun!
