Namespaces:

• Granite

Classes:

• AccelLabel - AccelLabel is meant to be used as a Gtk.MenuItem child for displaying a GLib.Action's accelerator alongside the Menu Item label.
• Application - This is the base class for all Granite-based apps. It has methods that help to create a great deal of an app's functionality.
• AsyncImage - AsyncImage is a Gtk.Image that provides a way to load icons and images asynchronously without blocking the main GTK thread.
• Dialog - Granite.Dialog is a styled Gtk.Dialog that uses an empty title area and action widgets in the bottom/end position.
• HeaderLabel - HeaderLabel is a start-aligned Gtk.Label with the Granite H4 style class
• HyperTextView - This class enables navigatable URLs in Gtk.TextView
• MessageDialog - MessageDialog is an elementary OS styled dialog used to display a message to the user.
• ModeSwitch - ModeSwitch is a selection control for choosing between two options that can be described with an icon.
• SeekBar - This widget is a playback statusbar that contains a Gtk.Scale widget and two labels displaying the current progression and the total duration.
• Settings - Granite.Settings provides a way to share Pantheon desktop settings with applications.
• SettingsPage - AbstractSettingsPage is a Gtk.ScrolledWindow subclass with properties used by other Granite settings widgets.
• SettingsSidebar - SettingsSidebar acts as a controller for a Gtk.Stack; it shows a row of buttons to switch between the various pages of the associated stack widget.

It provides feedback to users about the state of input validation and keeps track of its own validation state. By default, input is considered invalid.

  Compare two GLib.DateTime and return true if they occur on the same day of the same year
• public string seconds_to_time (int seconds)

• Utilities - A utility class for frequently-performed drawing operations.
• Services

Interfaces:

• Contract - Interface for executing and accessing properties of Contractor actions

• Utils - This namespace contains functions to apply CSS stylesheets to widgets.

Methods:

• public void apply_text_style_to_label (TextStyle text_style, Label label)
  This method applies given text style to given label
• public string? get_button_layout_schema ()
  This methods returns the schema used by Granite.Widgets.Utils.get_default_close_button_position to determine the close button placement. It will first check for the pantheon/gala schema and then fallback to the default gnome one. If neither is available, null is returned. Make sure to check for this case, as otherwise your program may crash on startup.
• public CssProvider? get_css_provider (string stylesheet)
  Constructs a new Gtk.CssProvider that will store the stylesheet data. This function uses Gtk.CssProvider.load_from_data internally so if this method fails then a warning will be thrown and null returned as a result.
• public bool get_default_close_button_position (out CloseButtonPosition position)
  This method detects the close button position as configured for the window manager. If you need to know when this key changed, it's best to listen on the schema returned by Granite.Widgets.Utils.get_button_layout_schema for changes and then call this method again.
• public CssProvider? set_color_primary (Widget window, RGBA color, int priority = STYLE_PROVIDER_PRIORITY_APPLICATION)
  Applies colorPrimary property to the window. The colorPrimary property currently changes the color of the Gtk.HeaderBar and it's children so that the application window can have a so-called "brand color".
• public CssProvider? set_theming (Widget widget, string stylesheet, string? class_name, int priority)
  Applies the stylesheet to the widget.
• public CssProvider? set_theming_for_screen (Screen screen, string stylesheet, int priority)
  Applies a stylesheet to the given screen. This will affect all the widgets which are part of that screen.
