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.to_widget(), frame.size());
}
```

<!-- cargo-rdme end -->

![demo](./examples/demo.png)

## 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(popup.to_widget(), 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 --
}
```
