Cut メソッド (EditBase)

コントロールの現在の選択項目をクリップボードに移動します。

構文

Visual Basic (宣言)
C#

Public Sub Cut()

public void Cut()

解説

Cutメソッドは、コントロールでテキストが選択されている場合に、コントロールからテキストだけを切り取ります。 Clipboardクラスの代わりにこのメソッドを使用すると、コントロールのテキストをコピーしてクリップボードに移動することができます。

使用例

派生クラス GcTextBox を使用するコード例を次に示します。切り取り、コピー、貼り付け、元に戻す、テキストの選択開始点や選択文字数の設定などの各操作を実行する System.Windows.Forms.MenuItem.Click オブジェクトの System.Windows.Forms.MenuItem イベントハンドラを用意します。

C#
Visual Basic

//  Please use the following namespace
//  using System.Windows.Forms;
//  using GrapeCity.Win.Editors;

private GcTextBox gcTextBox1 = new GcTextBox();
private void Menu_Copy(System.Object sender, System.EventArgs e)
{
    // Ensure that text is selected in the text box.   
    if (gcTextBox1.SelectionLength > 0)
        // Copy the selected text to the Clipboard.
        gcTextBox1.Copy();
}

private void Menu_Cut(System.Object sender, System.EventArgs e)
{
    // Ensure that text is currently selected in the text box.   
    if (gcTextBox1.SelectedText != "")
        // Cut the selected text in the control and paste it into the Clipboard.
        gcTextBox1.Cut();
}

private void Menu_Paste(System.Object sender, System.EventArgs e)
{
    // Determine if there is any text in the Clipboard to paste into the text box.
    if (Clipboard.GetDataObject().GetDataPresent(DataFormats.Text) == true)
    {
        // Determine if any text is selected in the text box.
        if (gcTextBox1.SelectionLength > 0)
        {
            // Ask user if they want to paste over currently selected text.
            if (MessageBox.Show("Do you want to paste over current selection?", "Cut Example", MessageBoxButtons.YesNo) == DialogResult.No)
                // Move selection to the point after the current selection and paste.
                gcTextBox1.SelectionStart = gcTextBox1.SelectionStart + gcTextBox1.SelectionLength;
        }
        // Paste current text in Clipboard into text box.
        gcTextBox1.Paste();
    }
}

private void Menu_Undo(System.Object sender, System.EventArgs e)
{
    // Determine if last operation can be undone in text box.   
    if (gcTextBox1.CanUndo == true)
    {
        // Undo the last operation.
        gcTextBox1.Undo();
        // Clear the undo buffer to prevent last action from being redone.
        gcTextBox1.ClearUndo();
    }
}
