redo

I am using a customized version of FingerPaint for Android with some other features, like inserting images and moving them. I decided to implement an Undo&Redo, since it will make life just easier. In order to implement it, I finally decided to use a Stack where I push the Drawing Cache of the view, and from where I push the content every time I want to go back to a previous state. So, using the FingerPaint as a basis, I have the following: private void touch_up() { mPath.lineTo(mX, mY); // commit the path to our offscreen mCanvas.drawPath(mPath, mPaint); // I enable the set drawing cache...

The default IntelliJ / Android Studio "Redo" action shortcut is CTRL + Shift + Z and this is a common problem for Windows users. A bigger problem is CTRL + Y is mapped to the "Delete line" action - and this causes the undo stack to be lost. To solve this issue, how can the "Redo" shortcut be changed to CTRL + Y in IntelliJ? İsmail Yavuz Open Settings (press CTRL + ALT + S ) Click Keymap on the left list. There is a combobox that contains keymaps. Select one of them (default means IntelliJ of course. We can't change any of pre-defined keymap however we can copy, edit and then use the edited one

In Vim, I did too much undo. How do I undo this (that is, redo)? Ctrl + r Also check out :undolist , which offers multiple paths through the undo history. This is useful if you accidentally type something after undoing too much. Strange nobody mentioned :earlier / :later . To redo everything you just need to do later 9999999d (assuming that you first edited the file at most 9999999 days ago), or, if you remember the difference between current undo state and needed one, use Nh , Nm or Ns for hours, minutes and seconds respectively. + :later N<CR> <=> Ng+ and :later Nf for file writes.

The only use case I can think of for redo would be for operations like writing to a socket or reading from a database, but if these fail once, subsequent attempts will most likely also fail so it still seems a bit pointless to me and as for retry I can't really think of any case where it would be useful. This might only seem meaningless to me since I don't know or use Ruby, but I aspire to create an awesome language one day so I would like to at least know reasoning behind design of some of the most popular languages out there. The idea is that you change something before calling redo or retry

Hi I'm about to add new functionality to application which I'm currently writting. I need to write a undo/redo fnctionality. However 90% of our application is ready and I don't know what is the best way to implementing this functionality without affectig(too much ) code which has been already created. There aren't many details here. However, Undo/Redo functionality is typically handled via some variation of the Command Pattern . Depending on your architecture, this could be a simple reworking of your basic functionality into "commands", or a major overhaul. ArBR As Reed Copsey says the most
