Auto save Editor [message #957625]

Usually in my gmf editors I was able to save the editors when some change happened in the editor.
Usually I used

OperationHistoryFactory.getOperationHistory().addOperationHistoryListener(new IOperationHistoryListener() {
public void historyNotification(OperationHistoryEvent event) {
    //save current editor Or editor itself
    doSave(new NullProgressMonitor());
}
}

In this case, The dirty state was never shown, the usability aspect was smooth, with no popups, no refreshing issues (trembling.. etc)

I was trying to do the same in graphiti, and it works, however the usability aspect is impared, once it shows two progress dialog for a fraction of second, even using Nullprogressmonitor.

Am I missing something? I would like that the user doesn't notice anything whenever editor is being saved, or at least that the character (*-dirty) doesn't appear in the tab.

Thanks in advance

Rui,

right, having a look into that coding I see that the passed monitor is
ignored and instead a monitor popup is opened in any case. Would you please
file that as a bugzilla?

Thanks,
Michael

Hi,
I tried to use Rui's idea. I put his code in the 'init' function of MyDiagramEditor, but the listener was not called. I looked in the Internet and found this code:

	
private IOperationHistory getOperationHistory() {
    IOperationHistory history = null;
    final TransactionalEditingDomain domain = getEditingDomain();
    if (domain != null) {
        final IWorkspaceCommandStack commandStack = (IWorkspaceCommandStack) getEditingDomain().getCommandStack();
        if (commandStack != null) {
            history = commandStack.getOperationHistory();
        }
    }
    return history;
}

I added also:

switch(event.getEventType()) {
    case OperationHistoryEvent.DONE:
    case OperationHistoryEvent.REDONE:
    case OperationHistoryEvent.UNDONE:
        doSave(new NullProgressMonitor());
	break;
}

in the listener.

In 0.9.2 mentioned problem is present. But my remark is that even after automatically save, the character (*-dirty) is appearing. Is it because of the way I retrived the IOperationHistory?

Marek,

I would suspect a timing issue as there is no guarantee in which sequence
listeners are called. It might happen that the diagram editor dirty state is
updated before your your save is done. Have you tried to add firing prop
dirty event after the save?
