Method Details

run

void run(CellLayout cellLayout,
 CellRenderer cell,
 TreeModel treeModel,
 TreeIter iter)

A function which should set the value of cellLayout’s cell renderer(s) as appropriate.

upcall

default void upcall(MemorySegment cellLayout,
 MemorySegment cell,
 MemorySegment treeModel,
