Method Summary

Modifier and Type	Method	Description
void	run(@Nullable HitTestResult hitTestResult, int modifiers)	This signal is emitted when the mouse cursor moves over an element such as a link, image or a media element.
default MemorySegment	toCallback(Arena arena)	Creates a native function pointer to the upcall(MemorySegment, MemorySegment, int) method.
default void	upcall(MemorySegment sourceWebView, MemorySegment hitTestResult, int modifiers)	The upcall method is called from native code.

Method Details

run

void run(@Nullable HitTestResult hitTestResult,
 int modifiers)

This signal is emitted when the mouse cursor moves over an element such as a link, image or a media element. To determine what type of element the mouse cursor is over, a Hit Test is performed on the current mouse coordinates and the result is passed in the hitTestResult argument. The modifiers argument is a bitmask of GdkModifierType flags indicating the state of modifier keys. The signal is emitted again when the mouse is moved out of the current element with a new hitTestResult.

upcall

default void upcall(MemorySegment sourceWebView,
 MemorySegment hitTestResult,
 int modifiers)

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

toCallback

default MemorySegment toCallback(Arena arena)

Creates a native function pointer to the upcall(MemorySegment, MemorySegment, int) method.

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the arena in which the function pointer is allocated

Returns:

the native function pointer
