NumberCellEditor

public NumberCellEditor(org.eclipse.swt.widgets.Composite parent,
                        Class<T> clazz)

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. Initially, the cell editor has no cell validator.

Parameters:

parent - the parent control

NumberCellEditor

public NumberCellEditor(org.eclipse.swt.widgets.Composite parent,
                        int style,
                        Class<T> clazz)

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. Initially, the cell editor has no cell validator.

parent - the parent control

style - the style bits

Method Detail

createControl

protected org.eclipse.swt.widgets.Control createControl(org.eclipse.swt.widgets.Composite parent)

Specified by:

createControl in class org.eclipse.jface.viewers.CellEditor

doGetValue

protected Object doGetValue()

The NumberCellEditor implementation of this CellEditor framework method returns the text string.

Specified by:

doGetValue in class org.eclipse.jface.viewers.CellEditor

Returns:

the text string

doSetFocus

protected void doSetFocus()

Specified by:

doSetFocus in class org.eclipse.jface.viewers.CellEditor

doSetValue

protected void doSetValue(Object value)

The NumberCellEditor implementation of this CellEditor framework method accepts a text string (type String).

Specified by:

doSetValue in class org.eclipse.jface.viewers.CellEditor

Parameters:

value - a text string (type String)

editOccured

protected void editOccured(org.eclipse.swt.events.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. Subclasses may extend or reimplement.

Parameters:

e - the SWT modify event

getLayoutData

public org.eclipse.jface.viewers.CellEditor.LayoutData getLayoutData()

Since a text editor field is scrollable we don't set a minimumSize.

Overrides:

getLayoutData in class org.eclipse.jface.viewers.CellEditor

handleDefaultSelection

protected void handleDefaultSelection(org.eclipse.swt.events.SelectionEvent event)

Handles a default selection event from the text control by applying the editor value and deactivating this cell editor.

Parameters:

event - the selection event

isCopyEnabled

public boolean isCopyEnabled()

The NumberCellEditor implementation of this CellEditor method returns true if the current selection is not empty.

Overrides:

isCopyEnabled in class org.eclipse.jface.viewers.CellEditor

isCutEnabled

public boolean isCutEnabled()

The NumberCellEditor implementation of this CellEditor method returns true if the current selection is not empty.

Overrides:

isCutEnabled in class org.eclipse.jface.viewers.CellEditor

isDeleteEnabled

public boolean isDeleteEnabled()

The NumberCellEditor 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.

Overrides:

isDeleteEnabled in class org.eclipse.jface.viewers.CellEditor

isPasteEnabled

public boolean isPasteEnabled()

The NumberCellEditor implementation of this CellEditor method always returns true.

Overrides:

isPasteEnabled in class org.eclipse.jface.viewers.CellEditor

isSaveAllEnabled

public boolean isSaveAllEnabled()

The NumberCellEditor implementation of this CellEditor method always returns true.

isSelectAllEnabled

public boolean isSelectAllEnabled()

Returns true if this cell editor is able to perform the select all action.

This default implementation always returns false.

Subclasses may override

Overrides:

isSelectAllEnabled in class org.eclipse.jface.viewers.CellEditor

Returns:

true if select all is possible, false otherwise

keyReleaseOccured

protected void keyReleaseOccured(org.eclipse.swt.events.KeyEvent keyEvent)

Processes a key release event that occurred in this cell editor.

The NumberCellEditor 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.

Overrides:

keyReleaseOccured in class org.eclipse.jface.viewers.CellEditor

Parameters:

keyEvent - the key event

performCopy

public void performCopy()

The NumberCellEditor implementation of this CellEditor method copies the current selection to the clipboard.
