tabcontrol OwnerDrawFixed在c＃中从右到左

Question

我想为每个标签添加X按钮。 drawMode是OwnerDrawFixed。如果从左到右，它可以正常工作。 一旦我允许RightToLeftLayout = true和RightToLeft = true，它看起来不太好，因为他仍然从左到右添加字符串，而该选项卡从右到左添加。

如何使字符串也从右到左？

private void addCloseButton(object sender, DrawItemEventArgs e)
{
    //This code will render a "x" mark at the end of the Tab caption. 
    e.Graphics.DrawString("x", e.Font, Brushes.Black, e.Bounds.Right - 15 , e.Bounds.Top +4 );
    e.Graphics.DrawString(this.tabControl1.TabPages[e.Index].Text, e.Font, Brushes.Black, e.Bounds.Left+4, e.Bounds.Top+4);
    e.DrawFocusRectangle();

}

private void actionClose(object sender, MouseEventArgs e)
{
    //Looping through the controls.
    for (int i = 0; i < this.tabControl1.TabPages.Count; i++)
    {
        Rectangle r = tabControl1.GetTabRect(i);
        //Getting the position of the "x" mark.
        Rectangle closeButton = new Rectangle(r.Right - 15, r.Top + 4, 12, 10);
        if (closeButton.Contains(e.Location))
        {
            if (MessageBox.Show("?האם אתה רוצה לסגור טאב זה", "אישור", MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.Yes)
            {
                this.tabControl1.TabPages.RemoveAt(i);
                break;
            }
        }
    }

}

Answer 1

将StringFormat标记设置为FormatFlags并将StringFormatFlags.DirectionRightToLeft传递给DrawString()：

StringFormat drawFormat = new StringFormat(StringFormatFlags.DirectionRightToLeft);

var bounds = new RectangleF(.. set actual bound rectangle for text... )    

e.Graphics.DrawString(this.tabControl1.TabPages[e.Index].Text, e.Font, Brushes.Black, bounds, drawFormat);
