GridBagLayout锚
GridBagLayout锚
提问于 2014-08-04 09:16:54
我试图使用Anchor设置我的组件的对齐方式。这是我的代码：
public void intiConOpt()
{
/*********************************** connection options ****************************************/
conOptGBC.insets = new Insets(5, 5, 5, 5);
conOptGBC.weightx = 1.0;
conOptGBC.weighty = 1.0;
conOptGBC.anchor = GridBagConstraints.NORTHWEST;
conOpt = new JPanel();
conOpt.setLayout(new GridBagLayout());
//////////////////////////////////////////cycle time////////////////////////////////////////////
readPeriodLabel = new JLabel("Node read cycle time:");
conOptGBC.gridx = 0;
conOptGBC.gridy = 0;
conOpt.add(readPeriodLabel, conOptGBC);
readPeriodNumberModel = new SpinnerNumberModel();
readPeriodSpinner = new JSpinner(readPeriodNumberModel);
JSpinner.NumberEditor readPeriodEditor = new JSpinner.NumberEditor(readPeriodSpinner,"###");
readPeriodSpinner.setEditor(readPeriodEditor);
readPeriodNumberModel.setValue(TopologyMain.settings.getSettingsList().get("nodeReadingCycleTime"));
readPeriodSpinner.setPreferredSize(new Dimension(40, 20));
conOptGBC.gridx = 1;
conOptGBC.gridy = 0;
conOpt.add(readPeriodSpinner, conOptGBC);
readPeriodLabel2 = new JLabel("<html><font size=2>(4-180 sec)</font></html>");
conOptGBC.gridx = 2;
conOptGBC.gridy = 0;
conOpt.add(readPeriodLabel2, conOptGBC);
///////////////////////////////////////////time out////////////////////////////////////////////
cliTimeoutLabel = new JLabel("CLI response timeout:");
conOptGBC.gridx = 0;
conOptGBC.gridy = 1;
conOpt.add(cliTimeoutLabel, conOptGBC);
cliTimeoutNumberModel = new SpinnerNumberModel();
cliTimeoutSpinner = new JSpinner(cliTimeoutNumberModel);
JSpinner.NumberEditor cliTimeoutEditor = new JSpinner.NumberEditor(cliTimeoutSpinner,"###");
cliTimeoutSpinner.setEditor(cliTimeoutEditor);
cliTimeoutNumberModel.setValue(TopologyMain.settings.getSettingsList().get("cliTimeout") /10);
cliTimeoutSpinner.setPreferredSize(new Dimension(40, 20));
conOptGBC.gridx = 1;
conOptGBC.gridy = 1;
conOpt.add(cliTimeoutSpinner, conOptGBC);
cliTimeoutLabel2 = new JLabel("<html><font size=2>(8-999 sec)</font></html>");
conOptGBC.gridx = 2;
conOptGBC.gridy = 1;
conOpt.add(cliTimeoutLabel2, conOptGBC);
///////////////////////////////////////busy response//////////////////////////////////////////////
cliBusySleepLabel = new JLabel("CLI busy check time:");
conOptGBC.gridx = 0;
conOptGBC.gridy = 2;
conOpt.add(cliBusySleepLabel, conOptGBC);
cliBusySleepNumberModel = new SpinnerNumberModel();
cliBusySleepSpinner = new JSpinner(cliBusySleepNumberModel);
JSpinner.NumberEditor cliBusySleepEditor = new JSpinner.NumberEditor(cliBusySleepSpinner,"###");
cliBusySleepSpinner.setEditor(cliBusySleepEditor);
cliBusySleepNumberModel.setValue(TopologyMain.settings.getSettingsList().get("cliBusySleep") /1000);
cliBusySleepSpinner.setPreferredSize(new Dimension(40, 20));
conOptGBC.gridx = 1;
conOptGBC.gridy = 2;
conOpt.add(cliBusySleepSpinner, conOptGBC);
cliBusySleepLabel2 = new JLabel("<html><font size=2>(1-999 sec)</font></html>");
conOptGBC.gridx = 2;
conOptGBC.gridy = 2;
conOpt.add(cliBusySleepLabel2, conOptGBC);
conOpt.setVisible(false);
contentPanel.add(conOpt);
}我的问题是GridBagConstraints锚没有影响，我的组件仍然在面板的中心。

anchor属性工作正常，您遇到的问题是.
conOptGBC.weightx = 1.0;
conOptGBC.weighty = 1.0;问题是，您已经要求GridBagLayout为每一列分配等量的空间，所以在这种情况下，它们将占用第三列，这就是要考虑的问题。
通过移除conOptGBC.weightx = 1.0;你得到..。
有点难看，但如果我们加些指南.
你可以看到田野开始向西北方向倾斜.
