ProjectTable

public class EnhancedTable

extends javax.swing.JTable

implements ViewActionReceiver, java.awt.print.Printable

EnhancedTable is a specialized table which has

• a persistent column model (JTable has a strange behaviour in this case, you have to overwrite createColumnModel to establish your own model, otherwise no colums are created)
• react on some action events

Method Detail

createDefaultColumnModel

protected javax.swing.table.TableColumnModel createDefaultColumnModel()

Returns the default column model object, which is a DefaultTableColumnModel. A subclass can override this method to return a different column model object.

Overrides:

createDefaultColumnModel in class javax.swing.JTable

Returns:

the default column model object

See Also:

DefaultTableColumnModel

unselectAll

public void unselectAll()

Unselects all items in a view

Specified by:

unselectAll in interface ViewActionReceiver

invertSelection

public void invertSelection()

Inverts current selection

Specified by:

invertSelection in interface ViewActionReceiver

getCellRenderer

public javax.swing.table.TableCellRenderer getCellRenderer(int row,
                                                           int column)

Returns an appropriate renderer for the cell specified by this row and column. If the TableColumn for this column has a non-null renderer, returns that. If not, finds the class of the data in this column (using getColumnClass) and returns the default renderer for this type of data.

Note: Throughout the table package, the internal implementations always use this method to provide renderers so that this default behavior can be safely overridden by a subclass.

Overrides:

getCellRenderer in class javax.swing.JTable

Parameters:

row - the row of the cell to render, where 0 is the first row

column - the column of the cell to render, where 0 is the first column

Returns:

the assigned renderer; if null returns the default renderer for this type of object

See Also:

DefaultTableCellRenderer, TableColumn.setCellRenderer(javax.swing.table.TableCellRenderer), JTable.setDefaultRenderer(java.lang.Class, javax.swing.table.TableCellRenderer)

getCellClass

public java.lang.Class getCellClass(int row,
                                    int col)

Return the class of the given cell. This method allows a more finegrained resolution of cell editors and renderers.

getCellEditor

public javax.swing.table.TableCellEditor getCellEditor(int row,
                                                       int column)

Returns an appropriate editor for the cell specified by row and column. If the TableColumn for this column has a non-null editor, returns that. If not, finds the class of the data in this column (using getColumnClass) and returns the default editor for this type of data.

Note: Throughout the table package, the internal implementations always use this method to provide editors so that this default behavior can be safely overridden by a subclass.

Overrides:

getCellEditor in class javax.swing.JTable

Parameters:

row - the row of the cell to edit, where 0 is the first row

column - the column of the cell to edit, where 0 is the first column

Returns:

the editor for this cell; if null return the default editor for this type of cell

See Also:

DefaultCellEditor

selectItem

public void selectItem(java.lang.Object pObject)

Select an object in the view

Specified by:

selectItem in interface ViewActionReceiver

Parameters:

pObject - Object to select in view

zoomIn

public void zoomIn()

Zooms current view, if applicable

Specified by:

zoomIn in interface ViewActionReceiver

zoomOut

public void zoomOut()

Unzooms current view, if applicable

Specified by:

zoomOut in interface ViewActionReceiver

narrow

public void narrow()

Narrows current view, if applicable

Specified by:

narrow in interface ViewActionReceiver

widen

public void widen()

Widens current view, if applicable

Specified by:

widen in interface ViewActionReceiver

canZoom

public boolean canZoom()

Returns true if view can be zoomed

Specified by:

canZoom in interface ViewActionReceiver

allowMultipleSelection

public boolean allowMultipleSelection()

Returns true if view allows multiple selection. If false, (un)selectAll and invertSelection actions are disabled

Specified by:

allowMultipleSelection in interface ViewActionReceiver

print

public int print(java.awt.Graphics graphics,
                 java.awt.print.PageFormat pageFormat,
                 int pageIndex)
          throws java.awt.print.PrinterException

Prints the page at the specified index into the specified Graphics context in the specified format. A PrinterJob calls the Printable interface to request that a page be rendered into the context specified by graphics. The format of the page to be drawn is specified by pageFormat. The zero based index of the requested page is specified by pageIndex. If the requested page does not exist then this method returns NO_SUCH_PAGE; otherwise PAGE_EXISTS is returned. The Graphics class or subclass implements the PrinterGraphics interface to provide additional information. If the Printable object aborts the print job then it throws a PrinterException.

Specified by:

print in interface java.awt.print.Printable

Parameters:

graphics - the context into which the page is drawn

pageFormat - the size and orientation of the page being drawn

pageIndex - the zero based index of the page to be drawn

Returns:

PAGE_EXISTS if the page is rendered successfully or NO_SUCH_PAGE if pageIndex specifies a non-existent page.

Throws:

java.awt.print.PrinterException - thrown when the print job is terminated.

getResizingColumn

public static javax.swing.table.TableColumn getResizingColumn(javax.swing.table.JTableHeader tableHeader,
                                                              java.awt.Point p,
                                                              int column)

Finds the column on that point and index for resizing.
Taken from BasisTableHeaderUI.

Returns:

the column or null

canResize

public static boolean canResize(javax.swing.table.JTableHeader tableHeader,
                                javax.swing.table.TableColumn column)

calcColumnWidth

public static void calcColumnWidth(javax.swing.JTable table,
                                   int col)

Calculates the optimal width for the column of the given table. The calculation is based on the preferred width of the header and cell renderer.
Taken from the newsgoup de.comp.lang.java with some modifications.

Parameters:

table - the table to calculate the column width

col - the column to calculate the widths
