GI.Gio.Objects.AppLaunchContext

Contents

Description

Integrating the launch with the launching application. This is used to handle for instance startup notification and launching the new application on the same screen as the launching window.

Synopsis

Exported types

class GObject o => IsAppLaunchContext o Source #

Type class for types which can be safely cast to AppLaunchContext, for instance with toAppLaunchContext.

toAppLaunchContext :: (MonadIO m, IsAppLaunchContext o) => o -> m AppLaunchContext Source #

Cast to AppLaunchContext, for types for which this is known to be safe. For general casts, use castTo.

Methods

getDisplay

appLaunchContextGetDisplay Source #

Arguments

:: (HasCallStack, MonadIO m, IsAppLaunchContext a, IsAppInfo b, IsFile c) 
=> a

context: a AppLaunchContext

-> b

info: a AppInfo

-> [c]

files: a List of File objects

-> m Text

Returns: a display string for the display.

Gets the display string for the context. This is used to ensure new applications are started on the same display as the launching application, by setting the DISPLAY environment variable.

getEnvironment

appLaunchContextGetEnvironment Source #

Arguments

:: (HasCallStack, MonadIO m, IsAppLaunchContext a) 
=> a

context: a AppLaunchContext

-> m [[Char]]

Returns: the child's environment

Gets the complete environment variable list to be passed to the child process when context is used to launch an application. This is a Nothing-terminated array of strings, where each string has the form KEY=VALUE.

Since: 2.32

getStartupNotifyId

appLaunchContextGetStartupNotifyId Source #

Arguments

:: (HasCallStack, MonadIO m, IsAppLaunchContext a, IsAppInfo b, IsFile c) 
=> a

context: a AppLaunchContext

-> b

info: a AppInfo

-> [c]

files: a List of of File objects

-> m Text

Returns: a startup notification ID for the application, or Nothing if not supported.

Initiates startup notification for the application and returns the DESKTOP_STARTUP_ID for the launched operation, if supported.

Startup notification IDs are defined in the FreeDesktop.Org Startup Notifications standard.

launchFailed

appLaunchContextLaunchFailed Source #

Arguments

:: (HasCallStack, MonadIO m, IsAppLaunchContext a) 
=> a

context: a AppLaunchContext.

-> Text

startupNotifyId: the startup notification id that was returned by appLaunchContextGetStartupNotifyId.

-> m () 

Called when an application has failed to launch, so that it can cancel the application startup notification started in appLaunchContextGetStartupNotifyId.

new

appLaunchContextNew Source #

Arguments

:: (HasCallStack, MonadIO m) 
=> m AppLaunchContext

Returns: a AppLaunchContext.

Creates a new application launch context. This is not normally used, instead you instantiate a subclass of this, such as GdkAppLaunchContext.

setenv

appLaunchContextSetenv Source #

Arguments

:: (HasCallStack, MonadIO m, IsAppLaunchContext a) 
=> a

context: a AppLaunchContext

-> [Char]

variable: the environment variable to set

-> [Char]

value: the value for to set the variable to.

-> m () 

Arranges for variable to be set to value in the child's environment when context is used to launch an application.

Since: 2.32

unsetenv

appLaunchContextUnsetenv Source #

Arguments

:: (HasCallStack, MonadIO m, IsAppLaunchContext a) 
=> a

context: a AppLaunchContext

-> [Char]

variable: the environment variable to remove

-> m () 

Arranges for variable to be unset in the child's environment when context is used to launch an application.

Since: 2.32

Signals

launchFailed

type AppLaunchContextLaunchFailedCallback Source #

Arguments

 = Text

startupNotifyId: the startup notification id for the failed launch

-> IO () 

The ::launch-failed signal is emitted when a AppInfo launch fails. The startup notification id is provided, so that the launcher can cancel the startup notification.

Since: 2.36

type C_AppLaunchContextLaunchFailedCallback = Ptr () -> CString -> Ptr () -> IO () Source #

Type for the callback on the (unwrapped) C side.

afterAppLaunchContextLaunchFailed :: (IsAppLaunchContext a, MonadIO m) => a -> AppLaunchContextLaunchFailedCallback -> m SignalHandlerId Source #

Connect a signal handler for the “launch-failed” signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after appLaunchContext #launchFailed callback

onAppLaunchContextLaunchFailed :: (IsAppLaunchContext a, MonadIO m) => a -> AppLaunchContextLaunchFailedCallback -> m SignalHandlerId Source #

Connect a signal handler for the “launch-failed” signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on appLaunchContext #launchFailed callback

launched

type AppLaunchContextLaunchedCallback Source #

Arguments

 = AppInfo

info: the AppInfo that was just launched

-> GVariant

platformData: additional platform-specific data for this launch

-> IO () 

The ::launched signal is emitted when a AppInfo is successfully launched. The platformData is an GVariant dictionary mapping strings to variants (ie a{sv}), which contains additional, platform-specific data about this launch. On UNIX, at least the "pid" and "startup-notification-id" keys will be present.

Since: 2.36

type C_AppLaunchContextLaunchedCallback = Ptr () -> Ptr AppInfo -> Ptr GVariant -> Ptr () -> IO () Source #

Type for the callback on the (unwrapped) C side.

afterAppLaunchContextLaunched :: (IsAppLaunchContext a, MonadIO m) => a -> AppLaunchContextLaunchedCallback -> m SignalHandlerId Source #

Connect a signal handler for the “launched” signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after appLaunchContext #launched callback

onAppLaunchContextLaunched :: (IsAppLaunchContext a, MonadIO m) => a -> AppLaunchContextLaunchedCallback -> m SignalHandlerId Source #

Connect a signal handler for the “launched” signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on appLaunchContext #launched callback
