Method Details

run

void run(int startPos,
 int endPos)

Emitted when text is deleted from the widget by the user.

The default handler for this signal will normally be responsible for deleting the text, so by connecting to this signal and then stopping the signal with g_signal_stop_emission(), it is possible to modify the range of deleted text, or prevent it from being deleted entirely.

The startPos and endPos parameters are interpreted as for Editable.deleteText(int, int).

upcall

default void upcall(MemorySegment sourceEditable,
 int startPos,
 int endPos)

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

toCallback

default MemorySegment toCallback(Arena arena)

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

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the arena in which the function pointer is allocated

Returns:

the native function pointer
