Gtk Comfy

Gtk Comfy is an effort to improve GTK builder files. Whilst the separation between code and interface is a good one, but the implementation is poor. XML is tricky and obtuse:

xml <?xml version="1.0" encoding="UTF-8"?> <interface> <object class="GtkApplicationWindow" id="window"> <property name="title">My GTK App</property> <child> <object class="GtkButton" id="button"> <property name="label">Press me!</property> <property name="margin-top">12</property> <property name="margin-bottom">12</property> <property name="margin-start">12</property> <property name="margin-end">12</property> </object> </child> </object> </interface>

So with GTK Comfy you can instead use any serde compatable format, as shown in the example below:

```yaml

The root interface

interface: # The class of the object (reserverd keyword) class: GtkApplicationWindow

# The id of the widget (reserved keyword)
id: window

# The title property. See that properties are automatically infered
title: My Gtk App

# The children
children:
-
    class: GtkButton
    id: Button
    label: Press me!
    margin-start: "12"
    margin-top: "12"
    margin-bottom: "12"
    margin-end: "12"

```

Gtk Comfy provides many convinience features, such as:

• Inferred properties, if it does not recognise a variable it will infer it as a property (see the title in the above example.)
• Child types, if a widget is given the child_type property than you can set the child type (I can’t remember when you need this but you do.)
• Pango Attributes. For labels (and suchlike) you can use attributes to provide a map of attributes (example below.)
• Style classes, provided in a style array.

An example of attributes:

yaml class: GtkLabel label: "This is a red label" attributes: foreground: '#FF0000'

An example of styles:

```yaml class: GtkBox orientation: "horizontal" style: - linked children:

...

```
