ofxUndo

undo/redo manager for openFrameworks

Usage

ofxUndoSimple

ofxUndoSimple directly stores data into history by equal(=) operator. Declare ofxUndoSimple with typename like ofxUndoSimple<ofVec2f> or ofxUndoSimple<MyStruct>. That's all you have to do to use this. NOTICE : It doesn't do anything like deep-copying. Be careful when you use it for pointers or structs that has pointers.

ofxUndoFile

ofxUndoFile provides interfaces for file I/O. Extend ofxUndoFile and implement save/load functions.

ofxUndoJson

ofxUndoJson makes it easier to store history in ofJson format. Declare ofxUndoJson with typename like ofxUndoJson<MyStruct>. Then implement toJson/loadJson in MyStruct.

I strongly recommend to use this class with @2bbb's ofxJsonUtils

ofxUndoCommandManager

ofxUndoCommandManager stores history as command data such as diffs or operations. Implement undo/redo members in ofxUndoCommand and pass it to Manager. Since the Manager expects commands as pointers, you can use any class by extending ofxUndoCommand.

ofxUndoGroup

With ofxUndoGroup, you can bind multiple ofxUndo-instances together. NOTICE: Don't undo/redo child instances directly while they belong to any group.
