Method Details

run

boolean run()

Emitted when JavaScript code calls <function>element.webkitRequestFullScreen</function>. If the signal is not handled the WebKitWebView will proceed to full screen its top level window. This signal can be used by client code to request permission to the user prior doing the full screen transition and eventually prepare the top-level window (e.g. hide some widgets that would otherwise be part of the full screen window).

upcall

default int upcall(MemorySegment sourceWebView)

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

toCallback

default MemorySegment toCallback(Arena arena)

Creates a native function pointer to the upcall(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
