UndoRedo | general purpose , functional style | Functional Programming library

I am implementing the system through inheritance, but there is an ambiguous part.

Parent class undostate child class recordstate

I made an undoredo function. And through this function, we are making a recording function. However, I want to make this function through inheritance. Because through undoredo, it seems that you can distinguish each action unit.

undoredo was implemented through the stack, but the recording function is similarly implemented by creating a record that inherits undoredo (the difference is to use a list).

The important thing here is that clicking the mouse creates an action But with the recordstate entering the record

Because I don't want to make two undoredostates entering undoredo (undoredo is the parent object of record)

I want to create and use recordstate, an object type that can be used in both places.

1. The question is, is it really a weird idea to try to put the same thing on the parent class's stack into the childclass list
2. Are there any design patterns associated with this?

I am using cytoscape js with react cytoscape and cytoscape undoRedo and cytoscape expand collapse. On first render I want to have layout by preset(I have all node's positions). It works well but when i perform api.collapseAll() it looks like nodes does not have these positions. Even though groupped nodes have the same position as parent. On expand I want to use cose bilkent layout. Is there a way to do it?

I get c2664 error when i try to create a unique pointer

i did write the copy constructor as well as assignment operator but still i keep getting the 2664 error

Is there a way to drawstring and then remove it?

I've used following classes to Undo/Redo Rectangle, Circle, Line, Arrow type shapes but cant figure how i can remove drawn string.

Here is how i'm adding Rectangle in shape list: This works well when i undo or redo from the list.

DrawString

So basically I was thinking of an undo-redo system (I've heard enough of memmento pattern and command pattern and I'm just gonna REEEEEEEEEE) where you'd make an object of this UndoRedo class inside any class that required a UR system and then every function that can be undone would start by generating a string of code that would undo the action (taking into account things like parameters passed to the function and any other related info) and push it to the undo stack of the URobject, which would handle the 2 stacks appropriately and have functions for undoing and redoing that just pop the code and eval it

Then I found this SO post about how to Eval in c# but it's useless because it's sandboxed and I need the Eval-ed code to communicate with the rest of my code and stuff.

Then, with @CodeCharmander's suggestion and @Fixation's clarification and a bit of research I managed to make it work!

I have onContextMenu events attached to a parent and child components. Both are react synthetic events, yet event.stopPropagation fails to stop this.

BOTH ARE REACT EVENTS

Edit: I had an epiphany,is it because im hydrating inside a content-editable div? and react doesnt know that both components are child and parent as react ignores content inside editable divs. is there a way to make react understand this?

ParentComponent

An error occurred when I ran the todos-with-undo project on the redux documentation page

'past' and 'future' do not exist when the program starts running.

My iOS application is crashed and I have the crash report but I cannot figure out the reason for crashing. The strange part is that this crashed has happened a little bit after application start and there is no indication of my code in crash report:
