とりあえずエラーは TabPage1 がクラスコンポーネントなので useDispatch などの hook 関数は使えません。
React の使い方というか、そもそも React とは何かについては、ちゃんと体系立てて学ぶことをお勧めします。サンプルコードを適当にいじれば何となく分かる、といった代物ではないので。
やっていること
RustのGUIフレームワーク、Tauriを使用してGUIを書いています。
ReactとReduxを使い、GUI（タブ分割）を実現したいと思っています。
やりたいこと
ボタンをクリックしたらRust側でカウントを1増やす。
UI側でタブを別タブに切り替える
戻したときにUIのステートが切り替える前と同じ状態に戻っていること
コード
rust
#![cfg_attr( all(not(debug_assertions), target_os = "windows"), windows_subsystem = "windows" )] fn main() { let context = tauri::generate_context!(); tauri::Builder::default() .invoke_handler(tauri::generate_handler![countup,]) .menu(tauri::Menu::os_default(&context.package_info().name)) .run(context) .expect("error while running tauri application"); } #[tauri::command] fn countup(count: i32) -> i32 { println!("{}", count + 1); count + 1 }
UI側

TypeScriptとReactが分からなさすぎてエラーを読んでも理解が出来ません。
具体的に何をどうしたらいいのでしょうか？
すごくふわっとしていて申し訳ないんですが、宜しくお願いします。
