Examples with ICellEditDialog org.eclipse.nebula.widgets.nattable.edit.gui.ICellEditDialog used on opensource projects

Example 1 with ICellEditDialog

use of org.eclipse.nebula.widgets.nattable.edit.gui.ICellEditDialog in project nebula.widgets.nattable by eclipse.

the class EditController method editCells.

/**
 * This method is used to edit cells in a sub dialog. In every case this
 * method will open a dialog for editing, regardless if the list of cells to
 * edit contain several or only one value. Only if the given list of cells
 * to edit is <code>null</code> or empty, there is no action performed.
 *
 * @param cells
 *            The list of cells to edit.
 * @param parent
 *            The parent composite to access the parent shell, or
 *            <code>null</code> to create a top-level shell dialog. In the
 *            last case, the dialog will be opened as non modal.
 * @param initialCanonicalValue
 *            The value that should be propagated to the editor control.
 *            Needed because for multi cell editing or editor activation by
 *            letter/digit key will result in a different value to populate
 *            for some editors than populating the value out of the
 *            cell/data model directly.
 * @param configRegistry
 *            The {@link IConfigRegistry} containing the configuration of
 *            the current NatTable instance the command should be executed
 *            for. This is necessary because the edit controllers in the
 *            current architecture are not aware of the instance they are
 *            running in and therefore it is needed for activation of
 *            editors.
