Hello,
first sorry for my bad english, but i hope you can understand my problem:
i created a tableviewer inside a IEditorPart which is editable and should jump to next cell right to the current one to edit it when you press the tab key. so far its working well, but when the tableviewer has horizontal and vertical scrollbars, they do not move coresponding to the tab event. i have manually to move them to the actual editing cell, to see and edit it. that is of course subotpimal, cause i want to get focus on the actual editing cell to see the content of the cell to edit it without moving the scrollbar manually. here is the code i have written:
TableViewerFocusCellManager focusCellManager = new TableViewerFocusCellManager(tableViewer, new FocusCellOwnerDrawHighlighter(tableViewer));
ColumnViewerEditorActivationStrategy actSupport = new ColumnViewerEditorActivationStrategy(tableVierwer {
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.eventType == ColumnViewerEditorActivationEvent.PROGRAMMATIC;
}};
TableViewerEditor.create(tableViewer, focusCellManager, actSupport, ColumnViewerEditor.TABBING_HORIZONTAL
| ColumnViewerEditor.TABBING_MOVE_TO_ROW_NEIGHBOR | ColumnViewerEditor.TABBING_VERTICAL | ColumnViewerEditor.KEYBOARD_ACTIVATION);

Hi,
for me this sounds similar to the case described in this bug:
289437: [Table] the arrow key couldn't move the table scrollbar
https://bugs.eclipse.org/bugs/show_bug.cgi?id=289437
RAP is currently using JFace 3.4 code base and
ViewerCell#scrollIntoView() and TableViewerRow#scrollCellIntoView( int )
are introduced in JFace 3.5. As Table#showColumn() has been added to RAP
in 1.3M2 ( see bug 279798 ), maybe it's possible to do this scrolling
yourself with RAP 1.3.
HTH,
Ivan
