UIng::Table

Inherits UIng::Control < UIng::BlockConstructor < Reference < Object

Table::Selection represents selected rows in a Table.

AUTOMATIC MEMORY MANAGEMENT: Table::Selection is automatically managed by the UIng library. Users do NOT need to manually free Table::Selection objects.

Recommended usage patterns:

Using on_selection_changed callback (RECOMMENDED): table.on_selection_changed do |selection| if selection.num_rows > 0 selected_row = selection.rows.first
... use selection data ...
end
Table::Selection is automatically freed after this block

end

Manual selection access (use with caution): selection = table.selection # Get selection rows = selection.num_rows # Extract data immediately

... use selection data ...

selection.free # MUST free manually when using this pattern

Setting a custom Table::Selection object via table.selection =: You can create a Table::Selection manually using Table::Selection.new(...) and assign it to a table. The data will be immediately copied or consumed by libui-ng, so the object does not need to be freed manually. Memory is automatically managed by Crystal's garbage collector.
