Method Details

run

void run(TextTag tag,
 TextIter start,
 TextIter end)

Emitted to remove all occurrences of tag from a range of text in a GtkTextBuffer.

Removal actually occurs in the default handler.

Note that if your handler runs before the default handler it must not invalidate the start and end iters (or has to revalidate them).

See also: TextBuffer.removeTag(org.gnome.gtk.TextTag, org.gnome.gtk.TextIter, org.gnome.gtk.TextIter).

upcall

default void upcall(MemorySegment sourceTextBuffer,
 MemorySegment tag,
 MemorySegment start,
 MemorySegment end)

The upcall method is called from native code. The parameters are marshaled and run(org.gnome.gtk.TextTag, org.gnome.gtk.TextIter, org.gnome.gtk.TextIter) 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:

toCallback in interface FunctionPointer

Parameters:

arena - the function pointer will be allocated in this arena

Returns:

the native function pointer
