After some users asking for answers in my past post, I updated the code of the embedded JTable to make it less buggy and more stable.
This is the "new" code:
/* We initialize the Objects where we'll store our data */
/* First an array Object which will be our main table */
Object[][] data = null;
/* We create an Array String to hold the name of the main table columns
In this example case we are going to store a contact name,
his email address(es) and his phone numer(s)
We're also going to store the creation date.*/
String[] columns = {"Name", "E-Mail","Phone","Creation Date"};
/* First thing is to populate our data object with some example values*/
public void populateData(){
/* Two contacts*/
data = new Object[3][columns.length];
data[0][0] = "Peter";
String[] emails = {"peter@yahoo.com", "strange@name.com"};
data[0][1] = emails;
String[] phones = {"555 35 25 65" , "555 35 24 63"};
data[0][2] = phones;
data[0][3] = new Date();
data[1][0] = "Jackson";
data[1][1] = "Jack@hotmail.com";
String[] phones2 = {"555 35 24 33" , "555 11 88 88", "332 55 25 34"};
data[1][2] = phones2;
data[1][3] = new Date();
data[2][0] = "Robert";
data[2][1] = "rob@hotmail.com";
data[2][2] = "555 28 95 81";
data[2][3] = new Date();
/* AS you can see, we've stored two contacts one with two e-mail
accounts and two phone numbers, and another member with three phone
numbers*/
}
/* Next we create our table models */
public void createModel(){
/* First we create the main model
We overide the AbstractTableModel necessary methods*/
AbstractTableModel modelo = new AbstractTableModel() {
public String getColumnName(int col) {
return columns[col].toString();
}
public Class getColumnClass(int col) {
if(getRowCount() <1)return null;
return data[0][col].getClass();
}
public int getRowCount() { return data.length; }
public int getColumnCount() { return columns.length;}
public Object getValueAt(int row, int col) {
return data[row][col];
}
public boolean isCellEditable(int row, int col){ return true; }
public void setValueAt(Object value, int row, int col) {
data[row][col] = value;
fireTableCellUpdated(row, col);
}};
/* We apply the model to the main jTable */
jTableData.setModel(modelo);
/* We create a cell Renderer to display the data of the multivalue
fields*/
TableCellRenderer jTableCellRenderer = new TableCellRenderer() {
/* Magic Happens */
public Component getTableCellRendererComponent(JTable table,
Object value, boolean isSelected, boolean hasFocus,
int row, int column) {
/* If what we're displaying isn't an array of values we
return the normal renderer*/
if(!value.getClass().isArray()){
return table.getDefaultRenderer(
value.getClass()).getTableCellRendererComponent(
table, value, isSelected, hasFocus,row, column);
}
else{
final Object[] passed = (Object[])value;
/* We create the table that will hold the multivalue
*fields and that will be embedded in the main table */
JTable embedded = new JTable(
new AbstractTableModel() {
public int getColumnCount() {
return 1;
}
public int getRowCount() {
return passed.length;
}
public Object getValueAt(int rowIndex, int columnIndex) {
return passed[rowIndex];
}
public boolean isCellEditable(int row, int col){ return true; }
});
if(isSelected){
embedded.setBackground(jTableData.getSelectionBackground());
embedded.setForeground(jTableData.getSelectionForeground());
}
if(hasFocus){
embedded.setRowSelectionInterval(0,1);
}
/* If this is what you plan to enable mouseClick detection,
in your table, IT WONT WORK. Have a look at TableCellEditor.*/
embedded.addMouseListener(new MouseAdapter() {
public void mouseClicked(java.awt.event.MouseEvent evt) {
System.out.println("PEPE");
}
});
setPreferredSize(embedded.getPreferredSize());
if(getPreferredSize().height != table.getRowHeight(row))
{
table.setRowHeight(row, getPreferredSize().height);
}
return embedded;
}
}
};
/* Finally we apply the new cellRenderer to the whole table */
TableColumnModel tcm = jTableData.getColumnModel();
for(int it = 0; it < tcm.getColumnCount(); it++){
tcm.getColumn(it).setCellRenderer(jTableCellRenderer);
// tcm.getColumn(it).setCellEditor(jTableCellEditor);
}
/*Note: if we need to edit the values inside the embedded jtable
* we will need to create a TableCellEditor too. */
}
In the above image you can see the result.
