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.

Since:

2.36

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 arena in which the function pointer is allocated

Returns:

the native function pointer
