Distribute GTK Apps with Windows (MSYS2)

Make sure package mingw-w64-x86_64-gtk3 is installed. Build your project with a custom prefix (e.g. ~/my-gtk-app-prefix). Navigate to this directory such that you have subdirectories 'bin', 'lib', 'share', etc containing the executable to distribute.

1. Dependent DLLs

The following command copies all dependent DLLs to the current directory:

// We have an object of type MyObject called 'obj'
// To use:
// replace 'obj' with your var name
// replace 'MY_TYPE_OBJECT' with the object's gtype

// snip

guint n_props;
GParamSpec **params = g_object_class_list_properties (G_OBJECT_GET_CLASS (obj), &n_props);
for (guint i = 0; i < n_props; i++)

Inkscape GTK 4 Port

What needs to be done?

GTK3 Backport Branch: https://gitlab.com/firox263/inkscape/-/tree/gtk4-prep-events GTK4 Transition Branch: https://gitlab.com/firox263/inkscape/-/tree/gtk4

Pre-Switch

• Replace all direct uses of GdkEvent
• Try move to event controllers where possible (not easy because GtkGestureClick doesn’t exist in GTK 3, which is basically all uses in Inkscape)
• Stop using generic containers (should be fine, only toolbars which currently use it)

Setting up Inkscape with CLion

These instructions are for macOS:

CMake options:

First set up cmake to check homebrew for dependencies.

We do this inside Preferences->Build, Execution, Deployment->CMake.

Matthew'z Zig Wishlist

From creating my 3D pixel game engine.

Pain Points:

• Lack of easy polymorphism: I currently used tagged unions and it's fine-ish, but having interfaces or traits in the language would make it infinitely more ergonomic to use.
• Casting is a nightmare: There really needs to be a shorter way to cast from int -> float and vice-versa. Compare C's (float) with Zig's @as(f32, @floatFromInt(...)). If I could write @floatFromInt(f32, ...) it would already be much better.

Nice to have:

• Comptime methods: I wanted to add swizzling methods for my custom vector struct, however you cannot generate methods at compile time (?). It would be nice to have a function e.g. Vector(dimension, components) which can then generate swizzle methods for each combination of components. I imagine calling vec.xyzz() and having that method be generated and even inlined at compile time.
• Easier way to do vector maths: I currently call vec.mul(other) but it would be nice to write vec * other. Th

Bit of a mouthful. This loads OpenGL symbols in Zig on macOS so you can pass it to gl.load(...).

Use it with https://github.com/MasterQ32/zig-opengl and a windowing system of your choice (e.g. GTK).
