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?
