Hello,

I have a treeviewer in which i'm using cell edition in TreeViewerColumn and when I activate the below code treeviewer.setselection is not working and when i remove the code the selection is working fine.

TreeViewerFocusCellManager focusCellManager = new TreeViewerFocusCellManager(treeViewer, new FocusCellOwnerDrawHighlighter(treeViewer));
ColumnViewerEditorActivationStrategy actSupport = new ColumnViewerEditorActivationStrategy(treeViewer) {
protected boolean isEditorActivationEvent(ColumnViewerEditorActivationEvent event) {
return event.keyCode == SWT.F2;
}
};

TreeViewerEditor.create(treeViewer, focusCellManager, actSupport, ColumnViewerEditor.TABBING_HORIZONTAL | ColumnViewerEditor.TABBING_MOVE_TO_ROW_NEIGHBOR | ColumnViewerEditor.TABBING_VERTICAL | ColumnViewerEditor.KEYBOARD_ACTIVATION);

Plz help

After investigation I have found the solution:

				Object selection = ((IStructuredSelection) sel).getFirstElement();
				if (selection instanceof MyObject) {
					treeViewer.setSelection(new StructuredSelection(selection), true);
					ViewerCell cell = treeViewer.getColumnViewerEditor().getFocusCell();
				}

And the selection is shown.

The owner draw highlighter remove the selection information using owner
draw.

Yes thank you Tom.

The selection is there, it's just not highlighted.

I will extend FocusCellHighlighter and enable the highlight of the selection.
