Hi there, I have a sortable list(jquery ui), could you advise if it is possible to implement 'undo/redo' base on sortable? Imagine that, a item is dragged to a new placeholder, then I click "undo" button and the item will move to its original position. If I click "redo" button and the item will move to that new placeholder. Maybe some...

Each time I do a transformation / add an filter I want to be able to go back to the previous image (befor...
While creating a customized editor with RichTextBox, I've face the problem of finding deleted/inserted text with the provided information with TextChanged event. The instance of TextChangedEventArgs has some useful data, but I guess it does not cover all the needs. Suppose a scenario which multiple paragraphs are inserted, and at the sa...
I am in the design process of an application, and I would like to use the command pattern for undo/redo purposes. I did some research into the command pattern but the only thing I don't get is: Should a command have the undo and redo methods, or should I make two separate commands, one for undo and one for redo, and call those from the m...
I have a Core Data document-based app which support undo/redo via the built-in NSUndoManager associated with the NSManagedObjectContext. I have a few actions set up which perform numerous tasks within Core Data, wrap all these tasks into an undo group via beginUndoGrouping/endUndoGrouping, and are processed by the NSUndoManager. Undo wo...
My app doesn't use Core Data yet. Is it true that I must use Core Data for undo/redo? And: How does the user do the undo/redo? I've never seen it in action, and never ever used it. Don't know how I should do it if I wanted to. There's no undo/redo button anywhere. Yet they say it has undo/redo. So how does the user trigger this? ...
Netbeans uses standard UndoManager API for implementation of undo functionality. But neither standard javax.swing.undo.UndoManager nor org.openide.awt.UndoRedo.Manager doesn't have any method to mark states as saved and check modified status. Nonetheless if you change the file and press undo, the file is marked as unmodified. How do they...
Problem In my iPad app, I cannot attach a popover to a button bar item only after press-and-hold events. But this seems to be standard for undo/redo. How do other apps do this? Background I have an undo button (UIBarButtonSystemItemUndo) in the toolbar of my UIKit (iPad) app. When I press the undo button, it fires it's action whic...

Hello... in my RCP - Project i'm using eclipse databinding to connect the ui with the backend. I want every change in an open editor to be undoable. My Domainmodell and UI are seperated in two different plugins. My current approach is to implement my own UpdateValueStrategy class for the databinding. I extend the normal UpdateValueSt...
I am implementing an undo/redo mechanism in my app. This works fine for lots of cases. However, I can't undo past deleteObject:. the object is correctly saved in the undo queue, and I get it back and reinsterted into the Core Data stack just fine when calling undo. The problem is that all it's attributes are getting set to nil when I...
Hi everybody, I have seen more and more of the websites that offers a undo option after pressing a delete button. How is the logic done behind the button? Is the item deleted by javascript and "dissapears" from the users screen and a scheduled delete added, that gives the user time to undo it or how does it work? What are the other op...

I am looking for a reference implementation (example) of a simple Delphi form that implements undo/redo. From what I have seen, simple delphi data-entry forms with three Edit boxes, six memo boxes, and a few combo boxes and ot...
I'm working on a Silverlight LoB app which the designers want to have a tabbed-interface, similar to the interface of Visual Studio (we'll probably use the Telerik Rad controls for docking tabs). Having done a prototype, the interface is working well so far, but I'm having problems thinking of how to implement undo/redo functionality in ...
