I am trying to get tabbing to work in a GridTreeViewer.

When I tab though the grid is trying to set focus on a disposed GridItem,
and I get the following stack trace:

java.lang.IllegalArgumentException: Argument not valid
at org.eclipse.nebula.widgets.grid.Grid.setFocusItem(Grid.java: 8000)
at
org.eclipse.nebula.jface.gridviewer.GridViewerEditor.updateF ocusCell(GridViewerEditor.java:91)
at
org.eclipse.jface.viewers.ColumnViewerEditor.activateCellEdi tor(ColumnViewerEditor.java:166)
at
org.eclipse.jface.viewers.ColumnViewerEditor.handleEditorAct ivationEvent(ColumnViewerEditor.java:377)
at
org.eclipse.jface.viewers.ColumnViewer.triggerEditorActivati onEvent(ColumnViewer.java:670)
at
org.eclipse.jface.viewers.ColumnViewerEditor.processTraverse Event(ColumnViewerEditor.java:490)
at
org.eclipse.jface.viewers.ColumnViewerEditor$4.keyTraversed( ColumnViewerEditor.java:219)

I am initializing with the follow settings:
GridViewerEditor.create(this, actSupport,
ColumnViewerEditor.TABBING_HORIZONTAL
| ColumnViewerEditor.TABBING_MOVE_TO_ROW_NEIGHBOR |
ColumnViewerEditor.TABBING_VERTICAL|
ColumnViewerEditor.KEYBOARD_ACTIVATION);

Does anyone have any ideas what I might be doing wrong?

Thanks

There's a bug in the GridViewerRow implementation IIRC. It's on my
schedule since a long time but I didn't manage to fix it.

hello,

use below code..

cell will be activated on tab traverse.might be useful

ColumnViewerEditorActivationStrategy actSupport = new
ColumnViewerEditorActivationStrategy(
gridTableViewer) {
protected boolean isEditorActivationEvent(
ColumnViewerEditorActivationEvent event) {
return event.eventType == ColumnViewerEditorActivationEvent.TRAVERSAL
|| event.eventType ==
ColumnViewerEditorActivationEvent.MOUSE_CLICK_SELECTION

|| (event.eventType == ColumnViewerEditorActivationEvent.KEY_PRESSED
&& event.keyCode == SWT.F2)
|| event.eventType == ColumnViewerEditorActivationEvent.PROGRAMMATIC;
}
};
GridViewerEditor.create(gridViewer, actSupport,
ColumnViewerEditor.TABBING_HORIZONTAL
| ColumnViewerEditor.TABBING_MOVE_TO_ROW_NEIGHBOR
| ColumnViewerEditor.TABBING_VERTICAL
| ColumnViewerEditor.KEYBOARD_ACTIVATION);
}

Thanks,
Raghava

thanks, however that is pretty much what I am doing. The tab works
sometimes, but if I explicitly select into a cell and then tab, then I get
the error as described.

As said there's a bug in the GridViewerRow implementation. Could you
please file a bug and attach a snippet I can run without modifications?
