Method Details

run

void run(String path)

Emitted when the user asks for it.

This is a keybinding signal.

This is used to make the file chooser show a "Location" prompt which the user can use to manually type the name of the file he wishes to select.

The default bindings for this signal are Control-L with a path string of "" (the empty string). It is also bound to / with a path string of "/" (a slash): this lets you type / and immediately type a path name. On Unix systems, this is bound to ~ (tilde) with a path string of "~" itself for access to home directories.

upcall

default void upcall(MemorySegment sourceFileChooserWidget,
 MemorySegment path)

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

default MemorySegment toCallback(Arena arena)

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

Specified by:
