Method Detail

addNotify

public void addNotify()

Overrides:

addNotify in class JComponent

removeNotify

public void removeNotify()

Overrides:

removeNotify in class JComponent

initialize

public void initialize(AWTEvent ev,
                       com.klg.jclass.cell.JCCellInfo info,
                       Object o)

Description copied from interface: JCCellEditor

The container calls initialize() before the edit starts to let the editor know what kind of event started the edit (via the AWTEvent object).
Note: The size of the cell comes from info.getDrawingArea().

Implementors must handle null AWTEvents.

Specified by:

initialize in interface JCCellEditor

Parameters:

ev - event that initiated the edit operation

info - cell that displays information for the editor

o - item to be edited

setBounds

public void setBounds(int x,
                      int y,
                      int width,
                      int height)

Overridden to make the image full size.

Overrides:

setBounds in class Component

Parameters:

height -

width -

x -

y -

getCellEditorValue

public Object getCellEditorValue()

Returns the object to be committed.

Specified by:

getCellEditorValue in interface JCCellEditor
