org.eclipse.jface.viewers.CellEditor
Abstract base class for cell editors. Implements property change listener handling, and SWT window management.
Subclasses implement particular kinds of cell editors. This package contains various specialized cell editors:
- TextCellEditor - for simple text strings
- ColorCellEditor - for colors
- ComboBoxCellEditor - value selected from drop-down combo box
- CheckboxCellEditor - boolean valued checkbox
- DialogCellEditor - value from arbitrary dialog
