AppInfoManager

Object Hierarchy:

Description:


public class AppInfoManager : Object

A singleton class that caches GLib.AppInfo objects. Singletons are evil, yes, but this on slightly less so because the exposed API is immutable.

To detect when any of the managed AppInfo objects changes, appears, or goes away listen for the 'changed' signal.

Static methods:

  • public static AppInfoManager get_default ()
    Get a ref to the singleton AppInfoManager
  • public static AppInfoManager get_instance ()

Methods:

  • public void clear ()
  • public unowned string[]? get_categories (string id)
    Look up XDG categories for for desktop id or file path @id. Returns null if id is not found. This method will do sync IO if the desktop file for @id is not already cached.

  • public unowned string[]? get_keywords (string id)
    Look up keywords for for desktop id or file path @id. The keywords will be an amalgamation of the X-GNOME-Keywords and X-AppInstall-Keywords fields from the .desktopfile.

So if you are living in an async world you must first do an async call to lookup_async(id) before calling this method, in which case no sync io will be done.
  • public string? get_path (string id)
    Look up the full path to the desktop file for desktop id @id. Returns null if @id is not found. This method will do sync IO if the desktop file for @id is not already cached. So if you are living in an async world you must first do an async call to lookup_async(id) before calling this method, in which case no sync io will be done.
