input.cpp field length.

[jgrillout]

I'm looking at the sample code for input.cpp. Is there a way to specify a fields length?

Hello @jgrillout, See this example:

• https://arthursonzogni.github.io/FTXUI/examples/?file=component/input
• https://github.com/ArthurSonzogni/FTXUI/blob/5112d9139dfdd58f80230d30514e3e5d58735839/examples/component/input.cpp#L39-L41C6

You can use CatchEvent to filter out characters beyond a given length:

std::string input_string = "example";
auto input = Input({
  .content = &input_string,
  .placeholder = "This input allows up to 10 characters"
});

// Filter out characters beyond the 10th one.
input |= CatchEvent([&input_string](Event event) {
  return event.is_character() && input_string.size() > 10;
});

Does it solves your use case?
