public class Table

extends javax.swing.JPanel

Table is a component class which inherits JPanel. It contains a JTable in a JScrollpane and methods for getting and setting both the data in the JTable and the column headers. You can also edit the look-and-feel of the table by for example setting the font in a table cell and the background color of the table.

Table

public Table(java.lang.Object[] headers,
             int[] widths,
             int numOfRows)

Instantiates a new Table with the specified column headers and column widths, as well as the number of empty rows which is added.

Parameters:

headers - Array of objects which are the column headers.

widths - Array of integers which are the column widths.

numOfRows - The number of rows which are added.

Table

public Table(java.lang.Object[] headers,
             int[] widths,
             java.lang.Object[][] data)

Instantiates a new Table with the specified column headers and column widths, and sets the table data to be the data in the specified array.

Parameters:

headers - Array of objects which are the column headers.

widths - Array of integers which are the column widths.

data - A 2D-table of objects which is the table data to be added.

Method Detail

getData

public java.lang.Object getData(int row,
                                int column)

Returs the data in the specified cell or null if an Exception is caught.

Parameters:

row - The cell's row number.

column - The cell's column number.

Returns:

The data in the table cell.

getFirstEmptyRowNumber

public int getFirstEmptyRowNumber()

Checks the first cell in every row, starting from the top, and returns the row number of the first row without any data. If none of the added rows (0 -> rowCount-1) is empty it returns rowCount.

Returns:

The row number of the first empty row in the table.

getRowCount

public int getRowCount()

Returns the number of rows in the table's model.

Returns:

The number of rows.

getRowForGAI

public int getRowForGAI(java.lang.String GAI)

Searches through the JTable for the specified GAI. If a matching GAI is found it returns the row number, else it returns -1.

Parameters:

GAI - The wanted GAI.

Returns:

The row number where the GAI was found or -1.

getSelectedRow
