org.eclipse.jface.viewers .CellEditor

org.eclipse.jface.viewers .TextCellEditor

TextCellEditor
public class TextCellEditor extends CellEditor (Code)
	A cell editor that manages a text entry field. The cell editor's value is the text string itself. This class may be instantiated; it is not intended to be subclassed.

Field Summary
protected Text	text The text control; initially `null`.

Constructor Summary
public	TextCellEditor() Creates a new text string cell editor with no control The cell editor value is the string itself, which is initially the empty string.
public	TextCellEditor(Composite parent) Creates a new text string cell editor parented under the given control. The cell editor value is the string itself, which is initially the empty string.
public	TextCellEditor(Composite parent, int style) Creates a new text string cell editor parented under the given control. The cell editor value is the string itself, which is initially the empty string.

Method Summary
protected Control	createControl(Composite parent)
boolean	dependsOnExternalFocusListener()
protected Object	doGetValue() The `TextCellEditor` implementation of this `CellEditor` framework method returns the text string.
protected void	doSetFocus()
protected void	doSetValue(Object value) The `TextCellEditor` implementation of this `CellEditor` framework method accepts a text string (type `String`).
protected void	editOccured(ModifyEvent e) Processes a modify event that occurred in this text cell editor. This framework method performs validation and sets the error message accordingly, and then reports a change via `fireEditorValueChanged`. Subclasses should call this method at appropriate times.
public LayoutData	getLayoutData() Since a text editor field is scrollable we don't set a minimumSize.
protected void	handleDefaultSelection(SelectionEvent event) Handles a default selection event from the text control by applying the editor value and deactivating this cell editor.
public boolean	isCopyEnabled() The `TextCellEditor` implementation of this `CellEditor` method returns `true` if the current selection is not empty.
public boolean	isCutEnabled() The `TextCellEditor` implementation of this `CellEditor` method returns `true` if the current selection is not empty.
public boolean	isDeleteEnabled() The `TextCellEditor` implementation of this `CellEditor` method returns `true` if there is a selection or if the caret is not positioned at the end of the text.
public boolean	isPasteEnabled() The `TextCellEditor` implementation of this `CellEditor` method always returns `true`.
public boolean	isSaveAllEnabled()
public boolean	isSelectAllEnabled() Returns `true` if this cell editor is able to perform the select all action.
protected void	keyReleaseOccured(KeyEvent keyEvent) Processes a key release event that occurred in this cell editor. The `TextCellEditor` implementation of this framework method ignores when the RETURN key is pressed since this is handled in `handleDefaultSelection`. An exception is made for Ctrl+Enter for multi-line texts, since a default selection event is not sent in this case.
public void	performCopy() The `TextCellEditor` implementation of this `CellEditor` method copies the current selection to the clipboard.
public void	performCut() The `TextCellEditor` implementation of this `CellEditor` method cuts the current selection to the clipboard.
public void	performDelete() The `TextCellEditor` implementation of this `CellEditor` method deletes the current selection or, if there is no selection, the character next character from the current position.
public void	performPaste() The `TextCellEditor` implementation of this `CellEditor` method pastes the the clipboard contents over the current selection.
public void	performSelectAll() The `TextCellEditor` implementation of this `CellEditor` method selects all of the current text.

Field Detail
