All known Subclasses: org.eclipse.jface.viewers.AbstractTableViewer, org.eclipse.jface.viewers.AbstractTreeViewer,
| ColumnViewer | | abstract public class ColumnViewer extends StructuredViewer (Code) | | The ColumnViewer is the abstract superclass of viewers that have columns
(e.g., AbstractTreeViewer and AbstractTableViewer). Concrete subclasses of
ColumnViewer should implement a matching concrete subclass of
ViewerColumn .
This class is not intended to be subclassed outside of the JFace
viewers framework.

CellLabelProvider.
If the label provider is an
ITableLabelProvider , then it
provides a separate label text and image for each column. | | protected void | triggerEditorActivationEvent(ColumnViewerEditorActivationEvent event)

| ColumnViewer | | public ColumnViewer()(Code) | | Create a new instance of the receiver.
|
| applyEditorValue | | protected void applyEditorValue()(Code) | | Apply the value of the active cell editor if one is active.
since:
3.3 |
| cancelEditing | | public void cancelEditing()(Code) | | Cancels a currently active cell editor if one is active. All changes
already done in the cell editor are lost.
since:
3.1 (in subclasses, added in 3.3 to abstract class) |
| clearLegacyEditingSetup | | void clearLegacyEditingSetup()(Code) | | |
| createViewerEditor | | abstract protected ColumnViewerEditor createViewerEditor()(Code) | | Creates the viewer editor used for editing cell contents. To be
implemented by subclasses.
the editor, or null if this viewer does notsupport editing cell contents. |
| doGetColumnCount | | abstract protected int doGetColumnCount()(Code) | | Returns the number of columns contained in the receiver. If no columns
were created by the programmer, this value is zero, despite the fact that
visually, one column of items may be visible. This occurs when the
programmer uses the column viewer like a list, adding elements but never
creating a column.
the number of columns

3.3 |
| editElement | | public void editElement(Object element, int column)(Code) | | Starts editing the given element at the given column index.
Parameters:
element - the model element
Parameters:
column - the column index
since:
3.1 (in subclasses, added in 3.3 to abstract class) |
| getCell | | ViewerCell getCell(Point point)(Code) | | Returns the viewer cell at the given widget-relative coordinates, or
null if there is no cell at that location
Parameters:
point - the widget-relative coordinates the cell or null if no cell is found at the givenpoint |
| getColumnViewerOwner | | abstract protected Widget getColumnViewerOwner(int columnIndex)(Code) | | Returns the column widget at the given column index.
Parameters:
columnIndex - the column index Widget the column widget |
| getItem | | protected Item getItem(int x, int y)(Code) | | |
| getItemAt | | abstract protected Item getItemAt(Point point)(Code) | | Returns the
Item at the given widget-relative coordinates, or
null if there is no item at the given coordinates.
Parameters:
point - the widget-relative coordinates the Item at the coordinates or null ifthere is no item at the given coordinates |
| getLabelProvider | | public CellLabelProvider getLabelProvider(int columnIndex)(Code) | | Returns the label provider associated with the column at the given index
or null if no column with this index is known.
Parameters:
columnIndex - the column index the label provider associated with the column ornull if no column with this index is known
since:
3.3 |
| getViewerColumn | | ViewerColumn getViewerColumn(int columnIndex)(Code) | | Returns the viewer column for the given column index.
Parameters:
columnIndex - the column index the viewer column at the given index, or null ifthere is none for the given index |
| getViewerRow | | protected ViewerRow getViewerRow(Point point)(Code) | | Returns the viewer row at the given widget-relative coordinates.
Parameters:
point - the widget-relative coordinates of the viewer row ViewerRow the row or null if no row is found atthe given coordinates |
| getViewerRowFromItem | | abstract protected ViewerRow getViewerRowFromItem(Widget item)(Code) | | Returns a
ViewerRow associated with the given row widget.
Implementations may re-use the same instance for different row widgets;
callers can only use the viewer row locally and until the next call to
this method.
Parameters:
item - the row widget ViewerRow a viewer row object |
| hookControl | | protected void hookControl(Control control)(Code) | | |
| hookEditingSupport | | protected void hookEditingSupport(Control control)(Code) | | Hook up the editing support. Subclasses may override.
Parameters:
control - the control you want to hook on |
| refresh | | public void refresh(Object element, boolean updateLabels)(Code) | | |
| setColumnProperties | | public void setColumnProperties(String[] columnProperties)(Code) | | Sets the column properties of this column viewer. The properties must
correspond with the columns of the control. They are used to identify the
column in a cell modifier. If editing is not supported by this viewer the
call simply has no effect.
Since 3.3, an alternative API is available, see
ViewerColumn.setEditingSupport(EditingSupport) for a more
flexible way of editing values in a column viewer.
Parameters:
columnProperties - the list of column properties

| setColumnViewerEditor | | public void setColumnViewerEditor(ColumnViewerEditor columnViewerEditor)(Code) | |
Parameters:
columnViewerEditor - the new column viewer editor |
| setLabelProvider | | public void setLabelProvider(IBaseLabelProvider labelProvider)(Code) | | The column viewer implementation of this Viewer framework
method ensures that the given label provider is an instance of
ITableLabelProvider, ILabelProvider, or
CellLabelProvider.
If the label provider is an
ITableLabelProvider , then it
provides a separate label text and image for each column. Implementers of
ITableLabelProvider may also implement
ITableColorProvider and/or
ITableFontProvider to provide
colors and/or fonts.
If the label provider is an ILabelProvider, then it
provides only the label text and image for the first column, and any
remaining columns are blank. Implementers of ILabelProvider
may also implement
IColorProvider and/or
IFontProvider to
provide colors and/or fonts.

| triggerEditorActivationEvent | | protected void triggerEditorActivationEvent(ColumnViewerEditorActivationEvent event)(Code) | | Invoking this method fires an editor activation event which tries to
enable the editor but before this event is passed to
ColumnViewerEditorActivationStrategy to see if this event should
really trigger editor activation
Parameters:
event - the activation event |
| updateCell | | ViewerCell updateCell(ViewerRow rowItem, int column, Object element)(Code) | | Update the cached cell object with the given row and column.
Parameters:
rowItem -
Parameters:
column - ViewerCell |
