GetAll() : Std.Object.T
Gets a list of all of the applications currently registered on this system.
For desktop files, this includes applications that have NoDisplay=true set or are excluded from display by means of OnlyShowIn or NotShowIn. See ShouldShow. The returned list does not include applications which have the Hidden key set.

appinfo | a T |
Returns | a string containing the appinfo's commandline, or NULL if this information is not available |
:GetDescription(self @ T) : Std.String.T
Gets a human-readable description of an installed application.
:GetDisplayName(self @ T) : Std.String.T
Gets the display name of the application. The display name is often more descriptive to the user than the name itself.
appinfo | a T. |
Returns | the display name of the application for appinfo, or the name if no display name is available. |
:GetExecutable(self @ T) : Std.String.T
Gets the executable's name for the installed application.
appinfo | a T |
Returns | a string containing the appinfo's application binaries name |
:GetIcon(self @ T) : Gtk.Gio.GIcon.T
Gets the icon for the application.
appinfo | a T. |
Returns | the default Gtk.Gio.GIcon.T for appinfo. [transfer none] |
:GetIcon(_ @ ParentT)
:GetId(self @ T) : Std.String.T
Gets the ID of an application. An id is a string that identifies the application. The exact format of the id is platform dependent. For instance, on Unix this is the desktop file id from the xdg menu specification.
Note that the returned ID may be NULL, depending on how the appinfo has been constructed.
appinfo | a T. |
Returns | a string containing the application's ID. |
:GetName(self @ T) : Std.String.T
Gets the installed name of the application.
appinfo | a T. |
Returns | the name of the application for appinfo. |
:Launch(self @ T, files @ Std.Object.T, launch_context @ Gtk.Gio.GAppLaunchContext.T, error @ Std.Object.T) : Std.Symbol.T
Launches the application. Passes files to the launched application as arguments, using the optional launch_context to get information about the details of the launcher (like what screen it is on). On error, error will be set accordingly.
To launch the application without arguments pass a NULL files list.
Note that even if the launch is successful the application launched can fail to start if it runs into problems during startup. There is no way to detect this.
Some URIs can be changed when passed through a GFile (for instance unsupported uris with strange formats like mailto:), so if you have a textual uri you want to pass in as argument, consider using LaunchUris instead.
On UNIX, this function sets the GIO_LAUNCHED_DESKTOP_FILE environment variable with the path of the launched desktop file and GIO_LAUNCHED_DESKTOP_FILE_PID to the process id of the launched process. This can be used to ignore GIO_LAUNCHED_DESKTOP_FILE, should it be inherited by further processes. The DISPLAY and DESKTOP_STARTUP_ID environment variables are also set, based on information provided in launch_context.
appinfo | a T |
files | a GList of Gtk.Gio.GFile.T objects. [element-type GFile] |
launch_context | a Gtk.Gio.GAppLaunchContext.T or NULL. [allow-none] |
error | a Gtk.Glib.GError.T |
Returns | TRUE on successful launch, FALSE otherwise. |

:LaunchUris(self @ T, uris @ Std.Object.T, launch_context @ Gtk.Gio.GAppLaunchContext.T, error @ Std.Object.T) : Std.Symbol.T

To launch the application without arguments pass a NULL uris list.
Note that even if the launch is successful the application launched can fail to start if it runs into problems during startup. There is no way to detect this.

T and Gtk.Gio.GAppLaunchContext.T are used for describing and launching applications installed on the system.
As of GLib 2.20, URIs will always be converted to POSIX paths (using Gtk.Gio.GFile.GetPath) when using Launch even if the application requested an URI and not a POSIX path. For example for an desktop-file based application with Exec key totem %U and a single URI, sftp://foo/file.avi, then /home/user/.gvfs/sftp on foo/file.avi will be passed. This will only work if a set of suitable GIO extensions (such as gvfs 2.26 compiled with FUSE support), is available and operational; if this is not the case, the URI will be passed unmodified to the application. Some URIs, such as mailto:, of course cannot be mapped to a POSIX path (in gvfs there's no FUSE mount for it); such URIs will be passed unmodified to the application.
Specifically for gvfs 2.26 and later, the POSIX URI will be mapped back to the GIO URI in the Gtk.Gio.GFile.T constructors (since gvfs implements the Gtk.Gio.GVfs.T extension point). As such, if the application needs to examine the URI, it needs to use Gtk.Gio.GFile.GetUri or similar on Gtk.Gio.GFile.T. In other words, an application cannot assume that the URI passed to e.g. g_file_new_for_commandline_arg() is equal to the result of Gtk.Gio.GFile.GetUri. The following snippet illustrates this:
This code will work when both cdda://sr0/Track 1.wav and /home/user/.gvfs/cdda on sr0/Track 1.wav is passed to the application. It should be noted that it's generally not safe for applications to rely on the format of a particular URIs. Different launcher applications (e.g. file managers) may have different ideas of what a given URI means.
