Hello
I would like to turn an org.eclipse.emf.common.command.Command instance
into an ICommand so I can pass it to my GEF commandStack with
ICommandProxy ?
What is the real way to deal with those
org.eclipse.emf.common.command.Command instance in a GMF context (at
least a TranscationnalEditingDomain)
THANKS

I finnaly wrote my own Bridge Class:
package --------------;
import org.eclipse.core.commands.ExecutionException;
import org.eclipse.core.commands.operations.IUndoableOperation;
import org.eclipse.core.runtime.NullProgressMonitor;
import org.eclipse.gef.commands.Command;
public class IUndoableOperationToGefCommandBridge extends Command {
private static final NullProgressMonitor NULL_PROGRESS_MONITOR = new
NullProgressMonitor();
private IUndoableOperation operation;
public IUndoableOperationToGefCommandBridge(IUndoableOperation operation) {
super(operation.getLabel());
this.operation = operation;
}
@Override
public boolean canExecute() {
return operation.canExecute();
}
@Override
public boolean canUndo() {
return operation.canUndo();
}
@Override
public Command chain(Command command) {
return super.chain(command);
}
@Override
public void dispose() {
operation.dispose();
}
@Override
public void execute() {
try {
operation.execute(NULL_PROGRESS_MONITOR,null);
} catch (ExecutionException e) {
e.printStackTrace();
}
}
@Override
public String getDebugLabel() {
return super.getDebugLabel();
}
@Override
public String getLabel() {
return super.getLabel();
}
@Override
public void redo() {
try {
operation.redo(NULL_PROGRESS_MONITOR,null);
} catch (ExecutionException e) {
e.printStackTrace();
}
}
@Override
public void setDebugLabel(String label) {
super.setDebugLabel(label);
}
@Override
public void setLabel(String label) {
super.setLabel(label);
}
@Override
public void undo() {
try {
operation.undo(NULL_PROGRESS_MONITOR,null);
} catch (ExecutionException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
