Description

Synopsis

Details

AppInfo and AppLaunchContext 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 fileGetPath when using appInfoLaunch 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: homeuser.gvfssftp 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 File constructors (since gvfs implements the GVfs extension point). As such, if the application needs to examine the URI, it needs to use fileGetUri or similar on File. In other words, an application cannot assume that the URI passed to e.g. 'fileNewForCommandlineArg ' is equal to the result of fileGetUri.

appInfoDup :: AppInfoClass appinfo => appinfo -> IO AppInfo Source #

Creates a duplicate of a AppInfo.

appInfoEqual Source #

Arguments

Checks if two AppInfos are equal.

appInfoGetId :: (AppInfoClass appinfo, GlibString string) => appinfo -> IO (Maybe string) Source #

Note that the returned ID may be Nothing, depending on how the appinfo has been constructed.

appInfoGetName Source #

=> appinfo
-> String	returns the name of the application for appinfo.

Gets the installed name of the application.

appInfoGetDisplayName Source #

Arguments

:: (AppInfoClass appinfo, GlibString string)
=> appinfo
-> string	returns the display name of the application for appinfo, or the name if no display name is available.

Gets the installed name of the application.

appInfoGetDescription Source #

Arguments

:: (AppInfoClass appinfo, GlibString string)
=> appinfo
-> Maybe string	returns a string containing a description of the application appinfo, or `Nothing` if none.

Gets a human-readable description of an installed application.

appInfoGetExecutable Source #

Arguments

:: (AppInfoClass appinfo, GlibString string)
=> appinfo
-> string	returns the executable of the application for appinfo.

Gets the executable's name for the installed application.

appInfoGetCommandline Source #

Arguments

:: AppInfoClass appinfo
=> appinfo
-> Maybe ByteString	returns a string containing the appinfo's commandline, or `Nothing` if this information is not available

Gets the commandline with which the application will be started.

appInfoGetIcon Source #

Arguments

:: AppInfoClass appinfo
=> appinfo
-> IO (Maybe Icon)	returns the default `Icon` for appinfo or `Nothing`

Gets the icon for the application.

appInfoLaunch Source #

Arguments

:: AppInfoClass appinfo
=> appinfo
-> [File]	`files` a list of `File` objects
-> Maybe AppLaunchContext	`launchContext` a `AppLaunchContext` or `Nothing`
-> IO ()

Launches the application. Passes files to the launched application as arguments, using the optional launchContext to get information about the details of the launcher (like what screen it is on). Throws a GError if an error occurs

To lauch the application without arguments pass a emtpy 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 File (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 appInfoLaunchUris instead.

appInfoSupportsFiles Source #

Arguments

:: AppInfoClass appinfo
=> appinfo
-> IO Bool	returns `True` if the appinfo supports files.

Checks if the application accepts files as arguments.

appInfoSupportsUris Source #

Arguments

=> appinfo
-> [string]	`uris` a list containing URIs to launch.
-> Maybe AppLaunchContext	`launchContext` a `AppLaunchContext` or `Nothing`
-> IO ()

Launches the application. Passes uris to the launched application as arguments, using the optional launchContext to get information about the details of the launcher (like what screen it is on). Throws a GError if an error occurs.

To lauch the application without arguments pass a empty 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.

appInfoShouldShow Source #

Arguments

:: AppInfoClass appinfo

On some platforms, there may be a difference between user-defined AppInfos which can be deleted, and system-wide ones which cannot. See appInfoCanDelete.
