我已经创建了一个方法来创建JTable如下：
public void refTable(String jobNo) {
Report rp = new Report();
final String noJob = jobNo;
Map<Integer, String> jMap = rp.getReportInfo(jobNo);
Map<Integer, String> sortedMap = new TreeMap<Integer, String>(jMap);
String[] row = new String[sortedMap.size()];
Integer[] no = new Integer[sortedMap.size()];
String[] stat = new String[sortedMap.size()];
Boolean[] dev = new Boolean[sortedMap.size()];
String[] remark = new String[sortedMap.size()];
Boolean[] rem = new Boolean[sortedMap.size()];
userRemark = new String[sortedMap.size()];
tabSize = sortedMap.size();
int i = 0;
for (Integer key : sortedMap.keySet()) {
no[i] = key;
String[] val = sortedMap.get(key).split("###");
if (val[0].trim().equals("DEV")) {
stat[i] = "FAIL";
} else {
stat[i] = val[0].trim();
}
row[i] = val[1].trim();
dev[i] = false;
remark[i] = "";
//remark[i] = false;
//if(userRemark1[i]!=null)
userRemark[i] = RemarkDropDownList.userOthersReamrk;
//else
//userRemark[i] ="";
rem[i] = false;
i++;
}
DefaultTableModel model = new DefaultTableModel();
model.fireTableDataChanged();
jTable1.setModel(model);
model.addColumn("No:", no);
model.addColumn("Status:", stat);
model.addColumn("Details:", row);
model.addColumn("Non-Deviation", dev);
model.addColumn("Remarks", remark);
model.addColumn("Remove", rem);
model.addColumn("UR", userRemark);
TableColumn col1 = jTable1.getColumnModel().getColumn(0);
col1.setPreferredWidth(30);
TableColumn col2 = jTable1.getColumnModel().getColumn(1);
col2.setPreferredWidth(30);
TableColumn col3 = jTable1.getColumnModel().getColumn(2);
TextRenderer renderer = new TextRenderer();
col3.setCellRenderer(renderer);
col3.setPreferredWidth(350);
CellRenderer cellRender = new CellRenderer();
TableColumn col4 = jTable1.getColumnModel().getColumn(3);
col4.setCellEditor(jTable1.getDefaultEditor(Boolean.class));
col4.setCellRenderer(cellRender);
col4.setPreferredWidth(50);
TableButton buttonEditor = new TableButton("Button");
buttonEditor.addTableButtonListener(new TableButtonListener() {
//@Override
public void tableButtonClicked(int row, int col) {
RemarkDropDownList rmk = new RemarkDropDownList(noJob, row);
rmk.setVisible(true);
//userRemark1[row] = RemarkDropDownList.userOthersReamrk;
//String test = RemarkDropDownList.userOthersReamrk;
}
});
TableColumn col5 = jTable1.getColumnModel().getColumn(4);
col5.setCellRenderer(buttonEditor);
col5.setCellEditor(buttonEditor);
TableColumn col6 = jTable1.getColumnModel().getColumn(5);
col6.setCellEditor(jTable1.getDefaultEditor(Boolean.class));
col6.setCellRenderer(jTable1.getDefaultRenderer(Boolean.class));
col6.setPreferredWidth(50);
jTable1.setShowGrid(true);
jTable1.setGridColor(Color.BLACK);
jTable1.setAutoCreateRowSorter(true);
}
在我JTable的第 5 列中，我像这样创建了一个按钮。
TableButton buttonEditor = new TableButton("Button");
buttonEditor.addTableButtonListener(new TableButtonListener() {
//@Override
public void tableButtonClicked(int row, int col) {
RemarkDropDownList rmk = new RemarkDropDownList(noJob, row);
rmk.setVisible(true);
//userRemark1[row] = RemarkDropDownList.userOthersReamrk;
//String test = RemarkDropDownList.userOthersReamrk;
}
});
TableColumn col5 = jTable1.getColumnModel().getColumn(4);
col5.setCellRenderer(buttonEditor);
col5.setCellEditor(buttonEditor);
JFrame该按钮基本上像这样在其中创建一个带有组合框的新按钮。
public class RemarkDropDownList extends javax.swing.JFrame {
public static String userOthersReamrk = "test";
private String userSelectedItem = "File Issue";
String jobno;
int rowNo;
public RemarkDropDownList() {
initComponents();
this.lblOthers.setVisible(false);
this.txtOthers.setVisible(false);
}
public RemarkDropDownList(String jobNo, int row) {
initComponents();
this.lblOthers.setVisible(false);
this.txtOthers.setVisible(false);
this.jobno = jobNo;
this.rowNo = row;
}
private void jComboBox1ActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:
JComboBox cb = (JComboBox)evt.getSource();
userSelectedItem = (String)cb.getSelectedItem();
if(userSelectedItem.equalsIgnoreCase("others"))
{
this.lblOthers.setVisible(true);
this.txtOthers.setVisible(true);
}
else
{
this.lblOthers.setVisible(false);
this.txtOthers.setVisible(false);
}
}
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:
if(userSelectedItem.equalsIgnoreCase("others"))
{
userOthersReamrk = txtOthers.getText().toString();
if(userOthersReamrk == null || userOthersReamrk.equalsIgnoreCase(""))
{
JOptionPane.showMessageDialog(null, "Please enter Remark");
}
}
else
{
userOthersReamrk = userSelectedItem;
//String [] remark = new String [1000];
///remark[rowNo] = userOthersReamrk;
ReportPanelMin rpm = new ReportPanelMin();
//rpm.userRemark1[rowNo] = remark[rowNo];
rpm.refTable(jobno);
this.setVisible(false);
}
}
}
一切正常，但最后一部分。我userOthersReamrk在RemarkDropDownList类（新类）中创建了一个静态全局变量（）来保存用户下拉选择的值。我再次调用该refTable函数来重新加载表，这样我就可以userOthersReamrk像这样将值分配给第 7 列userRemark = new String[sortedMap.size()];。当我调试时，我可以看到用户选择的值被分配给userRemark数组，但它没有在表中填充。test显示我贴在其中的默认值的列RemarkDropDownList。我知道代码很长，但我发布所有内容以更好地了解我在做什么。我需要更改什么/在哪里进行更改，以便我的用户选择的值显示在第 7 列中，而不是默认值。
