Setting focus cell in TableViewer

编程技术  /  houtizong 发布于 3年前   116

I would like to find a way to set focus to a cell in a multi-column table
by an internal Process other than the activation events listed in the code
below. One would expect that the setFocusCell(viewerCell) from
TableViewerFocusCellManager from SWTFocusCellManager would get the job
done, but it is not visible.

Suggestions for setting focus and highlighting a cell based on an internal
event?

Here's the set-up code for the TableViewer and related entities:

tableViewer = new TableViewer(parent, SWT.MULTI | SWT.H_SCROLL | SWT.V_SCROLL | SWT.BORDER | SWT.FULL_SELECTION); final Table table = tableViewer.getTable(); final TableViewerFocusCellManager mgr = new TableViewerFocusCellManager(tableViewer, new FocusCellOwnerDrawHighlighter(tableViewer)); final ColumnViewerEditorActivationStrategy actSupport = new ColumnViewerEditorActivationStrategy(tableViewer) { @Override protected boolean isEditorActivationEvent (ColumnViewerEditorActivationEvent event) { return event.eventType == ColumnViewerEditorActivationEvent.TRAVERSAL || event.eventType == ColumnViewerEditorActivationEvent.MOUSE_CLICK_SELECTION || event.eventType == ColumnViewerEditorActivationEvent.KEY_PRESSED && (event.keyCode == SWT.CR || event.character == ' ') || event.eventType == ColumnViewerEditorActivationEvent.PROGRAMMATIC; } }; TableViewerEditor.create(tableViewer, mgr, actSupport, ColumnViewerEditor.TABBING_HORIZONTAL | ColumnViewerEditor.TABBING_MOVE_TO_ROW_NEIGHBOR | ColumnViewerEditor.TABBING_VERTICAL | ColumnViewerEditor.KEYBOARD_ACTIVATION); TableViewerColumn column; final int[] styles = { SWT.LEAD, SWT.LEAD, SWT.LEAD, SWT.LEAD, SWT.LEAD, SWT.LEAD, SWT.LEAD}; for (int columnIndex = 0; columnIndex columnIndex++) { column = new TableViewerColumn(tableViewer, styles[columnIndex]); // etc. for each column, specifying setLabelProvider and setEditingSupport
