From ftxui::Element to std::string or char*

From ftxui::Element to std::string or char*

It is not possible, by design.

Ideally, you would provide a function mapping your data toward the UI.

Then updating your data would be "automatically" reflected in the UI without extra work of synchronizing the two.

Sorry for the "you are using FTXUI wrongly" reply 😅. I would be happy to suggest how to refactor your code to show you how this was envisioned. Feel free to post a link.

Unfortunately, I cannot provide a link to the project because it is a commercial project, and you will not have access to it.

I believe I am using your project correctly. My task is to save the entire log displayed on the screen within the application to the clipboard when a certain key combination is pressed. My question to you was to find a more optimized way to do this (as I believe). But since this possibility does not exist, I will come up with another optimal method.

I was thinking about using it this way:

// Application data from which the UI is derived from:
std::string data;

// A function: (data => UI)
auto ui = Renderer([&data]() {
  return paragraph(data);
})

// Event handler:
// - Return: Copy `data` into the Clipboard.
// - ...
ui |= CatchEvent([&data](Event& event) {
  if (event == Event::Return) {
    SaveToClipBoard(data);
    return true;
  }

  return false;
})

// Display the UI.
screen.Loop(ui);

There are no real need for a function (UI => data). This is only one-way (data => UI)
