James Westman bbad6988fa language: Fix some issues with menus Blueprint's handling of menus didn't line up with how GtkBuilder handles them. The root <menu> element must have an ID and may not have attributes, and menus may not be used inline in a property.		2022-03-13 00:00:07 -06:00

Blueprint

A markup language for GTK user interface files.

Motivation

GtkBuilder XML format is quite verbose, and many app developers don't like using WYSIWYG editors for creating UIs. Blueprint files are intended to be a concise, easy-to-read format that makes it easier to create and edit GTK UIs.

Internally, it compiles to GtkBuilder XML as part of an app's build system. It adds no new features, just makes the features that exist more accessible.

Another goal is to have excellent developer tooling--including a language server--so that less knowledge of the format is required. Hopefully this will increase adoption of cool advanced features like GtkExpression.

Example

Here is what the libshumate demo's UI definition looks like ported to this new format:

using Gtk 4.0;
using Shumate 1.0;

template ShumateDemoWindow : Gtk.ApplicationWindow {
  can-focus: yes;
  title: _("Shumate Demo");
  default-width: 800;
  default-height: 600;

  [titlebar]
  Gtk.HeaderBar {
    Gtk.DropDown layers_dropdown {
      notify::selected => on_layers_dropdown_notify_selected() swapped;
    }
  }

  Gtk.Overlay overlay {
    vexpand: true;
    Shumate.Map map {}

    [overlay]
    Shumate.Scale scale {
      halign: start;
      valign: end;
    }

    [overlay]
    Gtk.Box {
      orientation: vertical;
      halign: end;
      valign: end;

      Shumate.Compass compass {
        halign: end;
        map: map;
      }
      Shumate.License license {
        halign: end;
      }
    }
  }
}
