今回はGUIを作りました。

環境

Windows 11
.NET framework 4.8
Newtonsoft.Json 13.0.3 (from NuGet)

C#コード

まずはボタンとテキストボックスがセットになったユーザーコントロールを作りました。

using System;
using System.Windows.Forms;

namespace speech2text
{
    public class ButtonTextbox : UserControl
    {
        private TableLayoutPanel tlp;
        private Button button;
        private TextBox textbox;
        public event EventHandler ButtonClicked;
        public ButtonTextbox()
        {
            InitializeComponet();
        }
        private void InitializeComponet()
        {
            tlp = new TableLayoutPanel();
            button = new Button();
            button.Anchor = AnchorStyles.Left | AnchorStyles.Right;
            button.Click += (sender, e) =>
            {
                ButtonClicked?.Invoke(this, EventArgs.Empty);
            };

            textbox = new TextBox();
            textbox.Anchor = AnchorStyles.Left | AnchorStyles.Right;

            Dock = DockStyle.Fill;

            // TableLayoutPanel Settings
            tlp.RowCount = 1;
            tlp.ColumnCount = 2;
            tlp.Dock = DockStyle.Fill;
            tlp.ColumnStyles.Add(new ColumnStyle(SizeType.Percent, 20F));
            tlp.ColumnStyles.Add(new ColumnStyle(SizeType.Percent, 80F));

            tlp.Controls.Add(button, 0, 0);
            tlp.Controls.Add(textbox, 1, 0);

            Controls.Add(tlp);
        }
        public string ButtonText
        {
            get { return button.Text; }
            set { button.Text = value; }
        }
        public string TextBoxText
        {
            get { return textbox.Text; }
            set { textbox.Text = value; }
        }
    }
}

            }   
            
        }
    }
}

「settings.json」を用意しておけば読み込んでくれます。

{
    "interpreter":"D:\\reazonspeech\\env\\py311\\Scripts\\python.exe",
    "script":"D:\\reazonspeech\\run.py"
}
