私は、約10文字の文字列をDatagrigdの列に連結したhtmlテキストをレンダリングしようとしていました。私はそれをレンダリングすることはできますが、セルのサイズにはできません。私はこれをHBoxに埋め込み、それをセルに配置しようとしています。しかし、私は細胞に十分なスペースがあっても、HBoxが収縮しているのを見て、細胞にサイズ変更することはできません。誰かがこのHBoxをDatagridセルのサイズに合わせて私を助けてくれるでしょうか？Datagridアイテムのレンダリング
私はUpdateDisplayList（）を使用しようとしましたが、無限ループに入り、画面がフリーズしています。以下のコードを見つけてください。
以下は、レンダラーへの呼び出しを行うクラスです。誰かが私を助けてください。
