Kotlin Native GNOME (deprecated)

A set of tools to make GNOME application creation easy in Kotlin Native, with Glade UI integration.

---

⚠️ Deprecated:

This was a work in progress for lack of a better option. Then I discovered:

• java-gi: a java gtk4 binding, which does the job, seems very complete and well maintained
• compose-4-gtk: a very nice proof of concept to use GTK components through composables I feel these are better alternatives.

---

Features

• a lightweight GTK object binding: no wrapper objects, just extension functions & aliases
• a Glade UI gradle plugin: produces UI classes for type-safe widget access & glade file integration in the executable
• a sample app

Usage

Prerequisites:

sudo apt install libgtk-3-dev libtinfo5

Then in your build.gradle.kts:

repositories {
    mavenCentral()
}

And:

dependencies {
    implementation("org.mrlem.gnome:gtk-binding:0.2.0")
}

Next steps:

• to get started: take a look at the sample project.
• to learn more: see internals.

Current status

Still a work in progress:

• Glade gradle plugin: 100% complete
• API coverage is still incomplete:
  • signal handler support is partial: no callback data
  • data types is partial for some of them: bitfields, etc
  • some missing generations: Cairo
• platform support: Linux only for now

Other Kotlin native GTK projects around:

• kotlin-native-gtk: low-level wrappers bindings, GIR based
• kotlinx-gtk: high-level wrappers bindings, manually created
• gir2java: GIR file java descriptors generator

For an explanation about why I didn't rely on one of them, see the FAQ.
