Swing中使用GridBagLayout布局的時候

調整距離邊框距離

可以使用fill 屬性,搭配insets,類設置距離邊框的距離

  this.rulePane = new UIPanel();
  this.rulePane.setName("rulePane");

  GridBagLayout gridbag = new GridBagLayout();
  GridBagConstraints c = new GridBagConstraints();
  this.rulePane.setLayout(gridbag);

  c.fill = GridBagConstraints.BOTH;

  c.ipadx = 18;
  c.insets = new Insets(20, 10, 2, 400);
  
  /*c.anchor = GridBagConstraints.NORTH;
  c.weightx = 2;
  c.weighty = 1;*/

  // 當前集團 TODO
  c.gridwidth = GridBagConstraints.RELATIVE;
  this.rulePane.add(this.getlbGrp(), c);
  c.gridwidth = GridBagConstraints.REMAINDER;
  this.rulePane.add(this.getlbGrpcode(), c);
  // 歸零標志
  c.fill = GridBagConstraints.BOTH;
  c.insets = new Insets(2, 10, 2, 400);
  c.gridwidth = GridBagConstraints.RELATIVE;
  this.rulePane.add(this.getlblResetFlag(), c);
  c.gridwidth = GridBagConstraints.REMAINDER;
  this.rulePane.add(this.getcbbResetFlag(), c);

設置有布局的寬高

this.ruleMainPane.setPreferredSize(new Dimension(1001, 330));
GridBagLayout布局

其他的設置寬高

this.ruleTitlePane = new UIPanel();
this.ruleTitlePane.setName("ruleTitlePane");
this.ruleTitlePane.setBorder(new BorderCustomerLine());
this.ruleTitlePane.setLayout(new GridLayout());
this.ruleTitlePane.setBackground(new Color(204, 204, 204));
//Jack
this.ruleTitlePane.setBounds(24, 29, 970, 32);

this.ckbPrefix = new UICheckBox();
this.ckbPrefix.setName("ckbPrefix");
this.ckbPrefix.setText("");
this.ckbPrefix.setHorizontalAlignment(SwingConstants.CENTER);
//Jack
this.ckbPrefix.setBounds(23, 67, 122, 22);
