Method Detail

createContents

protected 
Control createContents(
Composite cell)
Description copied from class: DialogCellEditor
Creates the controls used to show the value of this cell editor.

The default implementation of this framework method creates a label widget, using the same font and background color as the parent control.

Subclasses may reimplement. If you reimplement this method, you should also reimplement updateContents.

Overrides:
createContents in class DialogCellEditor
Parameters:
cell - the control for this cell editor
Returns:
the underlying control

dispose

public void dispose()
Description copied from class: CellEditor
Disposes of this cell editor and frees any associated SWT resources.

Overrides:
dispose in class CellEditor

openDialogBox

protected 
Object openDialogBox(
Control cellEditorWindow)
Description copied from class: DialogCellEditor
Opens a dialog box under the given parent control and returns the dialog's value when it closes, or null if the dialog was canceled or no selection was made in the dialog.

This framework method must be implemented by concrete subclasses. It is called when the user has pressed the button and the dialog box must pop up.

Specified by:
openDialogBox in class DialogCellEditor
Parameters:
cellEditorWindow - the parent control cell editor's window so that a subclass can adjust the dialog box accordingly
Returns:
the selected value, or null if the dialog was canceled or no selection was made in the dialog

updateContents

protected void updateContents(
Object value)
Description copied from class: DialogCellEditor
Updates the controls showing the value of this cell editor.

The default implementation of this framework method just converts the passed object to a string using toString and sets this as the text of the label widget.

Subclasses may reimplement. If you reimplement this method, you should also reimplement createContents.

Overrides:
updateContents in class DialogCellEditor
Parameters:
value - the new value of this cell editor
