class UIng::Table::Model::Handler

• UIng::Table::Model::Handler
• Reference
• Object

Overview

Table model callbacks with closure support. Model retains the Handler and its Procs; native UserData points back to it. Direct LibUI callers must retain the Handler themselves.

Column count and types are sealed when first passed to libui-ng. cell_value returns a new owned Value (or nil where allowed), transferred to libui-ng. set_cell_value receives a borrowed Value?, valid only during that callback. Keep captured native resources unfreed while used.

  Ameba counts branches inside the C callback closures as branches of this initializer even though each closure is an independent handler.

• #num_rows(&block : -> Int32)
• #set_cell_value(&block : LibC::Int, LibC::Int, Value | Nil -> Nil)
• #set_cell_value(callback : Nil) : Nil
