java swing 表格相关操作
(1)设置表格数据
public static void setTableData3(JTable parameterTable_1,Map requestMap,boolean hasTextField,boolean isTF_table_cell,String[]columnNames) {
System.out.println("setTableData3");
int length = requestMap.size();
if (length > 0) {
Object[][] datas = new Object[length][];
int count = 0;
for (Object obj : requestMap.keySet()) {
Object val = requestMap.get(obj);
Object[] objs = new Object[3];
RadioButtonPanel panel = new RadioButtonPanel();
panel.init(hasTextField);
objs[2] = panel;
Color backColor=CustomColor.getMoreLightColor();
// objs[2]="c"+i;
if(isTF_table_cell){
JTextArea keyTA=new AssistPopupTextArea(String.valueOf(obj));
keyTA.setBackground(backColor);
objs[0] = new JScrollPane(keyTA);
}else{
objs[0] =obj;
}
if (ValueWidget.isNullOrEmpty(val) || val.equals("null")
|| val.equals("undefined")) {//配置文件中保存的是"null",而不是null
val = SystemHWUtil.EMPTY;
}
if(isTF_table_cell){
JTextArea valTA=new GenerateJsonTextArea(String.valueOf(val));
valTA.setBackground(backColor);
objs[1] = new JScrollPane(valTA);
}else{
objs[1] = val;
}
datas[count] = objs;
count++;
}//for
// setTableData2(parameterTable_1,datas,columnNames);
appendTableData(parameterTable_1, datas, columnNames);
}//if
}
private static void setTableData2(JTable parameterTable_1,Object[][] datas,String[]columnNames) {
DefaultTableModel model = new DefaultTableModel(datas, columnNames);
parameterTable_1.setModel(model);
parameterTable_1.setRowHeight(30);
// rendTable();
}
/***
* 追加,原有输入框仍保留,所以可以使用Ctrl+Z
* @param datas
*/
public static void appendTableData(JTable parameterTable_1,Object[][] datas,String[]columnNames){
int rowCount=parameterTable_1.getRowCount();
if(rowCount<1){//如果表格本来为空
setTableData2(parameterTable_1,datas,columnNames);
}else{//表格不为空
for(int i=0;i<rowCount;i++){
setTableValueAt(parameterTable_1,i, 0, datas);
setTableValueAt(parameterTable_1,i, 1, datas);
}
DefaultTableModel tableModel = (DefaultTableModel) parameterTable_1.getModel();
for(int i=rowCount;i<datas.length;i++){
tableModel.addRow(datas[i]);
}
}
}
/***
* 设置表格单元格的值
* @param rowIndex
* @param columnIndex
* @param datas
*/
private static void setTableValueAt(JTable parameterTable_1,int rowIndex,int columnIndex,Object[][] datas){
Object keyObj=datas[rowIndex][columnIndex];
if(keyObj instanceof JScrollPane){
JScrollPane js=(JScrollPane)keyObj;
JTextComponent tf=(JTextComponent)js.getViewport().getComponent(0);
keyObj = tf.getText();
}
String key=null;
if(keyObj instanceof String){
key=(String)keyObj;
}else{
key=String.valueOf(keyObj);
}
Object valueAtObj=parameterTable_1.getValueAt(rowIndex, columnIndex);
if(valueAtObj instanceof JScrollPane){
JScrollPane keyScrollPane=(JScrollPane)valueAtObj;
JTextArea keyTA=(JTextArea)keyScrollPane.getViewport().getComponent(0);
keyTA.setText(key);
}else{
parameterTable_1.setValueAt(keyObj, rowIndex, columnIndex);
}
}
应用:
if(requestInfoBean.isRequestBodyIsJson()){//"请求参数"表格不可用
requestBodyDataTA.setText(requestInfoBean.getRequestBodyData());
}else{
TableUtil3.setTableData3(parameterTable_1,requestInfoBean.getRequestParameters(),true,true,columnNames);
rendTable();
}
public void layoutTable( ) {
// Object[][] datas=new Object[1][2];
Object[][] datas=new Object[1][3];
for(int i=0;i<datas.length;i++){
Object[]objs=new Object[3];
RadioButtonPanel panel=new RadioButtonPanel();
panel.init();
objs[2]=panel;
if(AutoTestPanel.isTF_table_cell){
objs[0]= new JScrollPane(new AssistPopupTextArea()) ;
objs[1]=new JScrollPane(new GenerateJsonTextArea());
}
datas[i]=objs;
}
TableUtil3.appendTableData(parameterTable_1,datas,columnNames);
// setTableData2(datas);
// repaintTable();
}
(2)清空表格数据
/***
* 清空单元格<br>
* @param parameterTable_1
* @param rowIndex
* @param columnIndex
*/
private static void cleanTableValue(JTable parameterTable_1,int rowIndex,int columnIndex){
Object valueAtObj=parameterTable_1.getValueAt(rowIndex, columnIndex);
if(valueAtObj instanceof JScrollPane){
JScrollPane keyScrollPane=(JScrollPane)valueAtObj;
JTextArea keyTA=(JTextArea)keyScrollPane.getViewport().getComponent(0);
keyTA.setText(SystemHWUtil.EMPTY);
}else{
parameterTable_1.setValueAt(null, rowIndex, columnIndex);
}
}
/***
* 清空表格数据<br>
* @param parameterTable_1
*/
public static void cleanTableData(JTable parameterTable_1){
int rowCount=parameterTable_1.getRowCount();
if(rowCount>0){
for(int i=0;i<rowCount;i++){
cleanTableValue(parameterTable_1,i, 0);
cleanTableValue(parameterTable_1,i, 1);
}
}
}
应用:
JButton cleanUpTable_66 = new JButton("清空表格");
cleanUpTable_66.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
TableUtil3.cleanTableData(parameterTable_1);
parameterTable_1.repaint();
}
});
(3)给表格增加一行
/***
* 表格增加一行
*/
public static void addParameter(JTable parameterTable_1,String key,boolean hasTextField,boolean isTF_table_cell) {
System.out.println("增加一行");
DefaultTableModel tableModel = (DefaultTableModel) parameterTable_1.getModel();
RadioButtonPanel panel = new RadioButtonPanel();
panel.init(hasTextField);
String val=null;
if(!ValueWidget.isNullOrEmpty(key)){
if(key.contains("=")||key.contains(":")){
String[]strs=key.split("[:=]");
key=strs[0];
val=strs[1];
}
}
Object[] rowData =null;
if(isTF_table_cell){
Color clor=CustomColor.getMoreLightColor();
JTextArea keyTA=new AssistPopupTextArea(key);
keyTA.setBackground(clor);
JComponent keyTA2=new JScrollPane(keyTA);
JTextArea valTA=new GenerateJsonTextArea(val);
valTA.setBackground(clor);
JComponent valScroll=new JScrollPane(valTA);
rowData =new Object[]{keyTA2, valScroll, panel};
}else{
rowData =new Object[]{key, val, panel};
}
tableModel.addRow(rowData);
}
应用:
/***
* 表格增加一行
*/
private void addParameter(String key) {
TableUtil.addParameter(this.parameterTable_1, key,true,AutoTestPanel.isTF_table_cell);
}
JButton addRowButton = new JButton("添加");
addRowButton.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
addParameter(null);
}
});
