Question 1

How do I install GTK4.cr on macOS?

Accepted Answer

On macOS, use Homebrew to install dependencies with `brew install gobject-introspection gtk4`, then add the gtk4.cr dependency to your shard.yml and run `shards install`, as per the README. This sets up the necessary libraries for development.

Question 2

Is GTK4.cr suitable for beginners in GUI programming?

Accepted Answer

Not ideal for complete beginners, as it requires familiarity with both Crystal and GTK concepts; the poor documentation and complex setup can be challenging without prior experience in either area.

Question 3

GTK4.cr vs Electron for building desktop apps in Crystal?

Accepted Answer

GTK4.cr offers native performance and a lighter footprint with GTK4, while Electron provides web technologies but more overhead; choose GTK4.cr for native integration or Electron if you prioritize web-based UI and have Crystal backend needs.

Question 4

How to handle signals and events in GTK4.cr?

Accepted Answer

Use the GI-Crystal binding generator patterns: connect signal handlers to widgets like buttons, as shown in the tutorials, leveraging GTK's standard event system with idiomatic Crystal syntax for callbacks.

Question 5

What are the runtime dependencies for deploying a GTK4.cr app?

Accepted Answer

Only GTK libraries are needed at runtime, not GObject Introspection files, simplifying deployment after the initial setup, as specified in the README's runtime dependencies section.

Question 6

Can I use GTK4.cr with other Crystal shards or libraries?

Accepted Answer

Yes, but compatibility may vary due to Crystal's growing ecosystem; ensure other shards don't conflict with GTK dependencies, and check for community examples or integrations in projects like Tijolo.
