Method Details

run

void run(@Nullable Value form,
 @Nullable Frame sourceFrame,
 @Nullable Frame targetFrame)

This signal is emitted when form will imminently be submitted. It can no longer be cancelled. This event always occurs immediately before a form is submitted to its target, so use this event to reliably detect when a form is submitted. This signal is emitted after WebKitWebFormManager::will-send-submit-event if that signal is emitted.

Since:

2.40

upcall

default void upcall(MemorySegment sourceWebFormManager,
 MemorySegment form,
 MemorySegment sourceFrame,
 MemorySegment targetFrame)

The upcall method is called from native code. The parameters are marshaled and run(org.webkitgtk.jsc.Value, org.webkitgtk.webprocessextension.Frame, org.webkitgtk.webprocessextension.Frame) is executed.

toCallback

default MemorySegment toCallback(Arena arena)

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

Specified by:
