This commit attempts to split GdkWin32GLContext into two parts, one for WGL and the other for EGL (ANGLE), and attempts to simplify things a bit, by: * We are already creating a Win32 window to capture display changes, so we can just use that to act as our dummy window that we use to find out the pixel format that the system supports for WGL. We also use it to obtain the dummy legacy WGL context that we will always require to create our more advanced Core WGL contexts. * Like what is done in X11, store up the WGL pixel format or the EGLConfig in our GdkWin32Display. * Ensure we do not create the dummy WGL context unnecessarily. In this way, we can successfully create the WGL/EGL contexts, however there are some issues at this point: * For WGL, the code successfully initializes and realizes the WGL Contexts, but for some reason things became invisible. When running gtk4-demo, this can be verified by seeing the mouse cursor changing when moved to spots where one can resize the window, although they were invisible. * For EGL, the code initializes EGL but could not realize the EGL context as shaders failed to compile. It seems like the shader issue is definitely outside the scope of this MR. |

GTK — The GTK toolkit
General information
GTK is a multi-platform toolkit for creating graphical user interfaces. Offering a complete set of widgets, GTK is suitable for projects ranging from small one-off projects to complete application suites.
GTK is free software and part of the GNU Project. However, the licensing terms for GTK, the GNU LGPL, allow it to be used by all developers, including those developing proprietary software, without any license fees or royalties.

Nightly documentation can be found at
- Gtk: https://gnome.pages.gitlab.gnome.org/gtk/gtk4/
- Gdk: https://gnome.pages.gitlab.gnome.org/gtk/gdk4/
- Gsk: https://gnome.pages.gitlab.gnome.org/gtk/gsk4/
Nightly flatpaks of our demos can be installed from the GNOME Nightly repository:

Building and installing
In order to build GTK you will need:
You will also need various dependencies, based on the platform you are building for:
If you are building the X11 backend, you will also need:
- Xlib, and the following X extensions:
- xrandr
- xrender
- xi
- xext
- xfixes
- xcursor
- xdamage
- xcomposite
If you are building the Wayland backend, you will also need:
- Wayland-client
- Wayland-protocols
- Wayland-cursor
- Wayland-EGL
Once you have all the necessary dependencies, you can build GTK by using Meson:
$ meson _build .
$ cd _build
$ ninja
You can run the test suite using:
$ meson test
And, finally, you can install GTK using:
$ sudo ninja install
Complete information about installing GTK and related libraries can be found in the file:
docs/reference/gtk/html/gtk-building.html
Or online
How to report bugs
Bugs should be reported on the issues page.
In the bug report please include:
-
Information about your system. For instance:
- which version of GTK you are using
- what operating system and version
- for Linux, which distribution
- if you built GTK, the list of options used to configure the build
And anything else you think is relevant.
-
How to reproduce the bug.
If you can reproduce it with one of the demo applications that are built in the demos/ subdirectory, on one of the test programs that are built in the tests/ subdirectory, that will be most convenient. Otherwise, please include a short test program that exhibits the behavior. As a last resort, you can also provide a pointer to a larger piece of software that can be downloaded.
-
If the bug was a crash, the exact text that was printed out when the crash occurred.
-
Further information such as stack traces may be useful, but is not necessary.
