A popup widget for [Ratatui](https://ratatui.rs)
The popup widget is a simple widget that renders a popup in the center of the screen.
## Example
```rust
use ratatui::prelude::*;
use tui_popup::Popup;
fn render_popup(frame: &mut Frame) {
let popup = Popup::new("tui-popup demo", "Press any key to exit")
.style(Style::new().white().on_blue());
frame.render_widget(&popup, frame.size());
}
```

## State
The widget supports storing the position of the popup in PopupState. This is experimental and the
exact api for this will likely change.
```rust
use ratatui::prelude::*;
use tui_popup::Popup;
fn render_stateful_popup(frame: &mut Frame, popup_state: &mut PopupState) {
let popup = Popup::new("tui-popup demo", "Press any key to exit")
.style(Style::new().white().on_blue());
frame.render_stateful_widget_ref(popup, frame.size(), popup_state);
}
fn move_up(popup_state: &mut PopupState) {
popup_state.move_by(0, -1);
}
```
The popup can automatically handle being moved around by the mouse, by passing in the column and
row of Mouse Up / Down / Drag events. The current implemntation of this checks whether the click is
in the first row of the popup, otherwise ignores the event.
```rust
match event.read()? {
Event::Mouse(event) => {
match event.kind {
event::MouseEventKind::Down(MouseButton::Left) => {
popup_state.mouse_down(event.column, event.row)
}
event::MouseEventKind::Up(MouseButton::Left) => {
popup_state.mouse_up(event.column, event.row);
}
event::MouseEventKind::Drag(MouseButton::Left) => {
popup_state.mouse_drag(event.column, event.row);
}
_ => {}
};
}
// -- snip --
}
```

The popup also supports rendering arbitrary widgets by implementing SizedWidgetRef (or wrapping them
with the provided SizedWrapper). This makes it possible to support wrapping and scrolling in using a
`Paragraph` widget, or scrolling any amount of widgets using
[tui-scrollview](https://github.com/joshka/tui-scrollview/).
```rust
let sized_paragraph = SizedWrapper {
inner: paragraph,
width: 21,
height: 5,
};
let popup = Popup::new("scroll: ↑/↓ quit: Esc", sized_paragraph)
.style(Style::new().white().on_blue());
frame.render_widget_ref(popup, area);
```
