Abstract GTK widget basis macro.

All widget macros utilize this macro to generate required code. The widget macro defines how widgets are defined:

widget! {
    class <a css class string literal>
    properties <optional the 'keyword' stateful to listen to a locally defined state (see use_state)> {
        <gtk widget property>: <property value expression>
        ...
    }
    connections {
        <(store) if the store may be used in the following closure> <connector name>: <closure to call for the signal of the connector>
        ...
    }
    children [
        <any child expression like another widget macro or a component function>
    ]
}
