Question

在一项地雷项目中,我一直试图在JPanel witch上增加一名JConsonle,由另一个JPanel控制。

问题是,JConsole从JPanel上排5px。在I tought, 它是固定床位的集装箱,但在给它留下了红色的背景之后,我认识到,ole正在从顶头上 set5px。

I ve also tried to use BorderLayout to set it in the NORTH or CENTER of the JPanel but that dosent work either.

这是我的法典:

public class MonopolyPanel extends JPanel {

  JPanel consoleP = new JPanel();
  JConsole console = new JConsole();

  MonopolyPanel(){

   this.setLayout(new BoxLayout(this, BoxLayout.Y_AXIS));
   console.setPreferredSize(new Dimension(530, 300));  
   consoleP.add(console);
   this.add(consoleP);

  }
}

Answer 1

青少年被添加到青春期。缺省有流动资金,缺省有5px的纵向和横向差距。证实如果出现零缺口的流放,那么trick就应当

consoleP == new JPanel(new FlowLayout(align, 0, 0));

Answer 2

From my experience, the best and most flexible layout is GridBagLayout.

在Swaing I的99%的小组都是GridBagLayout,否则就不可能得到所有的权利。

由于这种布局,你可以确定重量、确切的间隔和间隔参数。

其他布局器是有限的,不能令人信服。

查阅<代码> 边界?

您可能有必要制定<代码>。 JPanel s or the JConsole s Border to an EmptyBorder, such as:

component.setBorder(BorderFactory.createEmptyBorder());

You might also look for something about insets in the Javadocs.
