我正在使用GridBagLayout制作一个StatusBar,看起来像图片中的那样。我有4个区域,所以我在第一个区域中有一个按钮,然后在第二个区域中有信息消息,然后我想再有两个区域(并且我也有第5个区域作为角落)。
按钮区域非常适合,因为内容始终是宽度相同的按钮。与拐角区域相同。信息区域必须获取所有可用空间。第三和第四区域必须具有固定值,与屏幕大小无关。
我怎样才能做到这一点?
我当前的代码是:
public MyStatusBar() {
setLayout(new GridBagLayout());
setPreferredSize(new Dimension(getWidth(), 23));
GridBagConstraints c = new GridBagConstraints();
botonDispositivo = new JButton("");
this.setText(0, "Disconnected");
URL imageUrl = getClass().getResource("resources/22x22/dispositivo01.png");
this.setButtonImg(imageUrl);
this.setButtonEnabled(false);
c.gridx = 0;
c.gridy = 0;
c.fill = GridBagConstraints.BOTH;
c.anchor = GridBagConstraints.WEST;
c.gridwidth = 1;
c.gridheight = 1;
this.add(botonDispositivo, c);
c.insets= new Insets(0,10,0,0);
c.gridx ++;
c.gridy = 0;
c.weightx = 0.7;
c.fill = GridBagConstraints.HORIZONTAL;
msgLabel = new JLabel("");
msgLabel.setPreferredSize(new Dimension(500, msgLabel.getHeight()));
this.add(msgLabel, c);
this.setText(1, "Waiting for potentiostat conection");
c.gridx ++;
c.gridy = 0;
c.weightx = 0.0;
c.fill = GridBagConstraints.NONE;
this.add(new SeparatorPanel(Color.GRAY, Color.WHITE), c);
c.gridx ++;
c.gridy = 0;
c.fill = GridBagConstraints.NONE;
c.weightx = 0.0;
overErrorLabel = new JLabel("");
overErrorLabel.setSize(new Dimension(150, overErrorLabel.getHeight()));
this.add(overErrorLabel, c);
//this.setText(2, "");
c.gridx ++;
c.gridy = 0;
c.weightx = 0.0;
c.fill = GridBagConstraints.NONE;
this.add(new SeparatorPanel(Color.GRAY, Color.WHITE), c);
c.gridx ++;
c.gridy = 0;
c.weightx = 0.0;
c.fill = GridBagConstraints.NONE;
c.anchor = GridBagConstraints.EAST;
timeLabel = new JLabel("");
timeLabel.setMinimumSize(new Dimension(150, timeLabel.getHeight()));
//timeLabel.setMaximumSize(new Dimension(150, timeLabel.getHeight()));
this.add(timeLabel, c);
//this.setText(3, "");
JPanel rightPanel = new JPanel(new GridBagLayout());
c.gridx ++;
c.gridy = 0;
c.weightx = 0.0;
c.fill = GridBagConstraints.BOTH;
rightPanel.add(new JLabel(new AngledLinesWindowsCornerIcon()), c);
rightPanel.setOpaque(false);
c.gridx ++;
c.gridy = 0;
c.fill = GridBagConstraints.BOTH;
this.add(rightPanel, c);
setBackground(SystemColor.control);
}
最佳答案
为了更好,最轻松地输出到GUI,最好查找Borderlayout
,JPanel#setPrefferedSize(200, 30);
的JButton
,并将Icon
和JLabel放入WEST area
JPanel#setPrefferedSize(200, 30);
(rightPanel)到EAST area
将另一个JPanel
放入CENTER area
