FileDialogCellEditor

public FileDialogCellEditor()

Method Detail

open

public int open()

Description copied from interface: ICellEditDialog

Opens this dialog, creating it first if it has not yet been created.

Specified in here for convenience so we only need to check against this interface for a dialog.

Specified by:

open in interface ICellEditDialog

Specified by:

open in class AbstractDialogCellEditor

Returns:

the return code

createDialogInstance

public org.eclipse.swt.widgets.FileDialog createDialogInstance()

Description copied from class: AbstractDialogCellEditor

Will create the dialog instance that should be wrapped by this AbstractDialogCellEditor. Note that you always need to create and return a new instance because on commit or close the dialog will be closed, which disposes the shell of the dialog. Therefore the instance will not be usable after commit/close.

Specified by:

createDialogInstance in class AbstractDialogCellEditor

Returns:

The dialog instance that should be wrapped by this AbstractDialogCellEditor

getDialogInstance

public org.eclipse.swt.widgets.FileDialog getDialogInstance()

Specified by:

getDialogInstance in class AbstractDialogCellEditor

Returns:

The current dialog instance that is wrapped by this AbstractDialogCellEditor

getEditorValue

public Object getEditorValue()

Description copied from interface: ICellEditor

Returns the current value in this editor prior to conversion. For a text editor that is used to edit integer values, this would mean it returns the text value instead of the converted integer value. This method is only intended to be used internally .

Specified by:

getEditorValue in interface ICellEditor

Specified by:

getEditorValue in class AbstractDialogCellEditor

Returns:

The current value in this editor prior to conversion.

setEditorValue

public void setEditorValue(Object value)

Description copied from interface: ICellEditor

Sets the given value to editor control. This method is used to put the display values to the wrapped editor.

Specified by:

Specified by:

setEditorValue in class AbstractDialogCellEditor

Parameters:

value - The display value to set to the wrapped editor control.

Specified by:

isClosed in interface ICellEditor

Specified by:

isClosed in class AbstractDialogCellEditor

Returns:
