OTable

The OTable is an extended class of JTable embedded with an ArrayList of Objects used to display and edit regular two-dimensional tables of cells. It uses a javax.swing.DefaultTableModel.

It allows to insert, remove, update and retrieve row data. Also, which data to display in the table.

Adding a row

In order to adding a new row to the OTable:

myOTable.addRow(obj, displayData);

Where obj is the object to be added to the ArrayList of Objects (so we can keep the reference of this object) and where displayData is an array of Objects.

By adding the new row it will be added to the end of the OTable.

You can insert the new row by using an Object[] variable. For example:

// Example 1: Using initialized array
Object[] displayData = new Object[2];
displayData[0] = "My data 1";
displayData[1] = "My data 2";
myOTable.addRow(obj, displayData); 

// Example 2: One-line initialization
Object[] displayData = new Object[]{ "My data 1", "My data 2", ...... };
myOTable.addRow(obj, displayData);

// Example 3: Using Anonymous array
myOTable.addRow(obj, new Object[]{ "My data 1", "My data2), ...... });

To keep it simple, addRow method uses displayData as a Variable Argument (Learn more about Varargs) so we can easily insert the display data separated by comma. For example:

myOTable.addRow(obj, obj1, obj2, objN, ...);

Inserting a row

In order to inserting a new row to the OTable:

myOTable.insertRow(index, obj, displayData);

Where index is the position of the row we want to insert, obj is the object we want to keep reference and displayData is the data to be display in the OTable.

By inserting the new row it will be added to the index/position specificied.

Removing a row

In order to remove a row:

int index = myOTable.getSelectedIndex();
myOTable.removeRow(index);

Where index is the position of the row we want to remove. In the example above we removed the selected index in the OTable.

Updating a row

In order to update a row:

myOTable.updateRow(index, obj, displayData);

Where index is the position we want to update, obj is the new object we want to keep reference and displayData is the new data to be display in the OTable.

Retrieving a row

In order to retrieve/get a row:

int index = myOTable.getSelectedIndex();
myOTable.getRow(index);

Where index is the position we want to retrieve. In the example above we retrieve the selected index object in the OTable.

Removing/clearing all rows

In order to remove all rows in the OTable:

myOTable.clear();
