Method Details
- run
  
  boolean run(String prefix)
  
  Emitted when the inline autocompletion is triggered.
  The default behaviour is to make the entry display the whole prefix and select the newly inserted part.
  Applications may connect to this signal in order to insert only a smaller part of the prefix into the entry - e.g. the entry used in the GtkFileChooser inserts only the part of the prefix up to the next '/'.
- upcall
  
  default int upcall(MemorySegment sourceEntryCompletion, MemorySegment prefix)
  
  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.
