Question

我有一只“JLabel”标语,显示如下文所示的错误信息。我的理解是,如果电文植根于html的标签内,则该标签应该是一字。然而,就我而言,标签似乎横向扩大。请允许我告诉我,我没有做什么? 或者,是否有更好的办法显示长期错误的信息?

该法典:

public class MyPanel extends JPanel {
  public MyPanel() {
    this.setLayout(new BoxLayout(this, BoxLayout.Y_AXIS));

    // Several JPanel objects inside

    // The last JPanel to show error messages

    JPanel panelErrMsg = new JPanel(new FlowLayout(FlowLayout.LEFT));

    this._lblError = new JLabel();
    this._lblError.setBorder(BorderFactory.createEmptyBorder(20, 10, 10, 10));
    this._lblError.setForeground(Color.RED);
    this._lblError.setFont(new Font("Courier New", Font.BOLD, 12));
    panelErrMsg.add(this._lblError);
    this.add(panelErrMsg);
  }

  private void DisplayMessage(String msg) {
    String newMessage = "<html><body>" + msg + "</body></html>";
    this._lblError.setText(newMessage);
  }

}

Answer 1

您可以在开放源头JIDE Commonrice Laborel上尝试。它支持你希望JLabel能够做的许多其他特征。

Answer 2

The label needs to have a maximum width for it to wrap. Try setting the maximum width or wrapping the text in a div tag with a width attribute.

Answer 3

采用<条码>BorderLayout,panelErrMsg,并将标签贴在挪威航天中心的位置上。
