Method Detail

createEditorControl

public NatCombo createEditorControl(org.eclipse.swt.widgets.Composite parent)

Description copied from interface: ICellEditor

Creates the editor control that is wrapped by this ICellEditor. Will use the style configurations in ConfigRegistry for styling the control.

Specified by:

createEditorControl in interface ICellEditor

Overrides:

createEditorControl in class ComboBoxCellEditor

Parameters:

parent - The Composite that will be the parent of the new editor control. Can not be null

Returns:

The created editor control that is wrapped by this ICellEditor.

setCanonicalValue

public void setCanonicalValue(Object canonicalValue)

Description copied from class: ComboBoxCellEditor

This implementation overrides the default implementation because of the special handling for comboboxes. It can handle multi selection and needs to transfer the converted values into a String array so the values in the combobox can be selected.

Specified by:

setCanonicalValue in interface ICellEditor

Overrides:

setCanonicalValue in class ComboBoxCellEditor

Parameters:

canonicalValue - The canonical value to be set to the wrapped editor control.

commit

public boolean commit(SelectionLayer.MoveDirectionEnum direction,
                      boolean closeAfterCommit)

Description copied from interface: ICellEditor

Commits the current value of this editor. Will first try to convert the current value. Then it is checked if the validation should be executed which can be specified via parameter. If that succeeds and the value can be committed to the data model, the editor will be closed afterwards.

Specified by:

commit in interface ICellEditor

Overrides:

commit in class AbstractCellEditor

Parameters:

direction - The direction the selection within the NatTable should move after commit has finished.

closeAfterCommit - flag to tell whether this editor needs to closed after the commit or if it should stay open.

Returns:

true if the commit operation succeeded, false if the current value could not be committed. A value might not be committed for example if the conversion or the validation failed.
