Hi,
I've implemented a functionality that allow an user to move an edit part
inside a container by using the arrow keys and now I need to not
deselect the edit part that have been moved (I have to reselect the edit
part to move it again)
Any hints to do that
Thanks

AbstractEditPart and force the viewer to not deselect the current edit part
but it doesn't work ...

In the GEF documentation it's written
Closely related to selection is focus. Focus is a single editpart
maintained by the EditPartViewer. Focus is used when manipulating
selection via keyboard. By moving focus, the user can navigate from one
editpart to another without changing the current selection. The user can
add/remove the focused editpart from the selection. If focus is not
explicitly set, it is the same as the primary selected part.
In my drag edit part I added a viewer.setFocus(selectedEditPart) but the
method getFocusEditPart() is never called

I've tryed to set the focus and the selected value in the drag edit part
like this
chep.setSelected(EditPart.SELECTED_PRIMARY);
viewer.setFocus(chep);
and I see at debug time than the AbstractEditPart setSelected method was
called by the notifyChanged method
so I added the following code to ensure the selected edit part is setted
correctly
//test code
if (notification.getEventType() == 1) {
WidgetEditPart editPart = this;
if (editPart.getFigure().getChildren().size() > 0) {
if (editPart.getFigure().getChildren().get(0) instanceof ColumnHeader) {
EditPart columnHeaderEditPart = (EditPart)
editPart.getChildren().get(0);
columnHeaderEditPart.setSelected(EditPart.SELECTED_PRIMARY);
getViewer().setFocus(columnHeaderEditPart);
}
}
}
but is still doesn't select the edit part
