Question

我需要在Word文档中提取段落方向（.doc和.docx）。

对于.doc文档，我使用 paragraph.cloneProperties().getFBiDi 来获取段落的方向信息。
对于.docx文档，我使用 paragraph.getCTP != null && paragraph.getCTP.isSetPPr && paragraph.getCTP.getPPr.isSetBidi 。

当HWPFDocument或XWPFDocument读取阿拉伯语/希伯来语文档时，我希望getFBiDi / isSetBiDi为RTL段落返回TRUE。但是，它返回FALSE表示＆＃34; LTR＆＃34;某些文件的方向see the example。

我是否使用了错误的API来获取段落说明？

使用以下行设置方向：

class Form1 : Form
{
    private Rectangle hitTestRectangle = new Rectangle();
    private Rectangle doubleClickRectangle = new Rectangle();
    private TextBox textBox1 = new TextBox();
    private Timer doubleClickTimer = new Timer();
    private ProgressBar doubleClickBar = new ProgressBar();
    private Label label1 = new Label();
    private Label label2 = new Label();
    private bool isFirstClick = true;
    private bool isDoubleClick = false;
    private int milliseconds = 0;

    [STAThread]
    public static void Main()
    {
        Application.EnableVisualStyles();
        Application.Run(new Form1());
    }

    public Form1()
    {
        label1.Location = new Point(30, 5);
        label1.Size = new Size(100, 15);
        label1.Text = "Hit test rectangle:";

        label2.Location = new Point(30, 70);
        label2.Size = new Size(100, 15);
        label2.Text = "Double click timer:";

        hitTestRectangle.Location = new Point(30, 20);
        hitTestRectangle.Size = new Size(100, 40);

        doubleClickTimer.Interval = 100;
        doubleClickTimer.Tick +=
            new EventHandler(doubleClickTimer_Tick);

        doubleClickBar.Location = new Point(30, 85);
        doubleClickBar.Minimum = 0;
        doubleClickBar.Maximum = SystemInformation.DoubleClickTime;

        textBox1.Location = new Point(30, 120);
        textBox1.Size = new Size(200, 100);
        textBox1.AutoSize = false;
        textBox1.Multiline = true;

        this.Paint += new PaintEventHandler(Form1_Paint);
        this.MouseDown += new MouseEventHandler(Form1_MouseDown);
        this.Controls.AddRange(new Control[] { doubleClickBar, textBox1,
            label1, label2 });
    }

    // Detect a valid single click or double click.
    void Form1_MouseDown(object sender, MouseEventArgs e)
    {
        // Verify that the mouse click is in the main hit
        // test rectangle.
        if (!hitTestRectangle.Contains(e.Location))
        {
            return;
        }

        // This is the first mouse click.
        if (isFirstClick)
        {
            isFirstClick = false;

            // Determine the location and size of the double click 
            // rectangle area to draw around the cursor point.
            doubleClickRectangle = new Rectangle(
                e.X - (SystemInformation.DoubleClickSize.Width / 2),
                e.Y - (SystemInformation.DoubleClickSize.Height / 2),
                SystemInformation.DoubleClickSize.Width,
                SystemInformation.DoubleClickSize.Height);
            Invalidate();

            // Start the double click timer.
            doubleClickTimer.Start();
        }

        // This is the second mouse click.
        else
        {
            // Verify that the mouse click is within the double click
            // rectangle and is within the system-defined double 
            // click period.
            if (doubleClickRectangle.Contains(e.Location) &&
                milliseconds < SystemInformation.DoubleClickTime)
            {
                isDoubleClick = true;
            }
        }
    }

    void doubleClickTimer_Tick(object sender, EventArgs e)
    {
        milliseconds += 100;
        doubleClickBar.Increment(100);

        // The timer has reached the double click time limit.
        if (milliseconds >= SystemInformation.DoubleClickTime)
        {
            doubleClickTimer.Stop();

            if (isDoubleClick)
            {
                textBox1.AppendText("Perform double click action");
                textBox1.AppendText(Environment.NewLine);
            }
            else
            {
                textBox1.AppendText("Perform single click action");
                textBox1.AppendText(Environment.NewLine);
            }

            // Allow the MouseDown event handler to process clicks again.
            isFirstClick = true;
            isDoubleClick = false;
            milliseconds = 0;
            doubleClickBar.Value = 0;
        }
    }

    // Paint the hit test and double click rectangles.
    void Form1_Paint(object sender, PaintEventArgs e)
    {
        // Draw the border of the main hit test rectangle.
        e.Graphics.DrawRectangle(Pens.Black, hitTestRectangle);

        // Fill in the double click rectangle.
        e.Graphics.FillRectangle(Brushes.Blue, doubleClickRectangle);
    }
}

使用Apache POI库在Word中提取错误的段落方向
