Add alert widget about ftxui HOT 8 CLOSED

Yes, sorry.
I had a predefined idea about how this should be implemented and wanted to complete it. Thanks for filling this issue, this forced me to complete it.

Thanks you!

I initially hoped we could get this using the "dbox" Element.
This is a container (like hbox, vbox) that superpose the elements.

It turns out I also needed some few more features:

• Adding the TakeFocus() function to component.
• Adding the clear_under Element

I just added an example: ./examples/component/modal_dialog.cpp
This is on the dev branch.

This give me:

This is mostly included in this pull request:

Ohhh, Great man !!

I thought I would be able to contribute this 😄

Have you thought about baking this modal functionality into the ComponentBase such that you'd always have the functionality to call showModal(ModalComponent component) where we have something like using ModalComponent = std::shared_ptr<ModalComonentBase>? And then dismiss could be just on the ModalComponent and it held a reference to its host ComponentBase which would toggle the depth variable for us.

What about creating an API like this;

auto main_component  = ...;
auto modal = ...;

bool show_modal = false;
auto main_component_and_modal = Modal(main_component, modal, &show_modal);

Alternatively we are now supporting "nested" InteractiveScreen. So you can already use right now:

void ShowModal() {
  auto modal_screen = ...;
  auto modal_component = ...;
  modal_screen.Loop(modal_component);
}

void main() {
  auto main_screen = ...;
  auto main_component = ... (show_modal);
  main_screen.Loop(main_component);
}

I added Modal in the PR. What do you think of it?

Yup, looks good to me! Thanks!
