Method Summary

Modifier and Type	Method	Description
void	run(String startupNotifyId)	The Gio.AppLaunchContext::launch-failed signal is emitted when a AppInfo launch fails.
default MemorySegment	toCallback(Arena arena)	Creates a native function pointer to the upcall(java.lang.foreign.MemorySegment, java.lang.foreign.MemorySegment) method.
default void	upcall(MemorySegment sourceAppLaunchContext, MemorySegment startupNotifyId)	The upcall method is called from native code.

Method Details

run

void run(String startupNotifyId)

The Gio.AppLaunchContext::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.

Because a launch operation may involve spawning multiple instances of the target application, you should expect this signal to be emitted multiple times, one for each spawned instance.

upcall

default void upcall(MemorySegment sourceAppLaunchContext,
 MemorySegment startupNotifyId)

The upcall method is called from native code. The parameters are marshaled and run(java.lang.String) is executed.

toCallback

default MemorySegment toCallback(Arena arena)

Creates a native function pointer to the upcall(java.lang.foreign.MemorySegment, java.lang.foreign.MemorySegment) method.

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the function pointer will be allocated in this arena

Returns:

the native function pointer
