## Detailed Description

DesktopAppInfo is an implementation of AppInfo based on desktop files.

Since glibmm 2.16:

## Constructor & Destructor Documentation

virtual Gio::DesktopAppInfo::~DesktopAppInfo | ( |  | ) | `[virtual]`

## Member Function Documentation

static Glib::RefPtr<DesktopAppInfo> Gio::DesktopAppInfo::create | ( | const std::string & | desktop_id | ) | `[static]`

Creates a new DesktopAppInfo based on a desktop file id.

A desktop file id is the basename of the desktop file, including the .desktop extension. GIO is looking for a desktop file with this name in the <filename>applications</filename> subdirectories of the XDG data directories (i.e. the directories specified in the <envar>XDG_DATA_HOME</envar> and <envar>XDG_DATA_DIRS</envar> environment variables). GIO also supports the prefix-to-subdirectory mapping that is described in the ).

Parameters:

  desktop_id | The desktop file id.

Returns:
  A new DesktopAppInfo, or `0` if no desktop file with that id.

static Glib::RefPtr<DesktopAppInfo> Gio::DesktopAppInfo::create_from_filename | ( | const std::string & | filename | ) | `[static]`

Creates a new DesktopAppInfo.

Parameters:

  filename | The path of a desktop file, in the GLib filename encoding.

Returns:
  A new DesktopAppInfo or `0` on error.

static Glib::RefPtr<DesktopAppInfo> Gio::DesktopAppInfo::create_from_keyfile | ( | Glib::KeyFile& | key_file | ) | `[static]`

Creates a new DesktopAppInfo.

Since glibmm 2.18:

Parameters:

  key_file | An opened KeyFile.

Returns:
  A new DesktopAppInfo or `0` on error.

std::string Gio::DesktopAppInfo::get_filename | ( |  | ) | const

When info was created from a known filename, return it.

In some situations such as the DesktopAppInfo returned from g_desktop_app_info_new_from_keyfile(), this function will return `0`.

Since glibmm 2.24:

Returns:
  The full path to the file for info, or `0` if not known.

const GDesktopAppInfo* Gio::DesktopAppInfo::gobj | ( |  | ) | const`[inline]`

Provides access to the underlying C GObject.

Reimplemented from Gio::AppInfo.

GDesktopAppInfo* Gio::DesktopAppInfo::gobj | ( |  | ) | `[inline]`

Provides access to the underlying C GObject.

Reimplemented from Gio::AppInfo.

GDesktopAppInfo* Gio::DesktopAppInfo::gobj_copy | ( |  | ) |

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

bool Gio::DesktopAppInfo::is_hidden | ( |  | ) | const

A desktop file is hidden if the Hidden key in it is set to True.

Returns:
  `true` if hidden, `false` otherwise.

static void Gio::DesktopAppInfo::set_desktop_env | ( | const std::string & | desktop_env | ) | `[static]`

Sets the name of the desktop that the application is running in.

This is used by g_app_info_should_show() to evaluate the `OnlyShowIn` and `NotShowIn` desktop entry fields.

The

Should be called only once; subsequent calls are ignored.

Parameters:

  desktop_env | A string specifying what desktop this is.

## Friends And Related Function Documentation

Glib::RefPtr< Gio::DesktopAppInfo > wrap | ( | GDesktopAppInfo * | object,
|  | bool | take_copy = `false`
| ) |  | `[related]`

A Glib::wrap() method for this object.

Parameters:

  object | The C instance.
  take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns:
  A C++ instance that wraps this C instance.
