アプリでカラーチューザーダイアログを使用したい-https ://github.com/satya164/gtk-theme-config
ValaでColorChooserDialogに関するドキュメントが見つかりません。現在、カラーボタンを使用して色を選択しています。しかし、コンパイル中に次の非推奨の警告が表示されます。Vala0.16.1とGTK3.6を使用しています（警告はGTK3.4には表示されません）。ColorChooserダイアログの使用に関するサンプルが見つかりません。誰かが私がColorChooserDialogを実装するのを手伝ってくれるなら、私は本当に感謝するでしょう。
