Center a Rect
You can use a Vertical
layout followed by a Horizontal
layout to get a centered Rect
.
/// # Usage
///
/// ```rust
/// let rect = centered_rect(f.size(), 50, 50);
/// ```
fn centered_rect(r: Rect, percent_x: u16, percent_y: u16) -> Rect {
let popup_layout = Layout::default()
.direction(Direction::Vertical)
.constraints(
[
Constraint::Percentage((100 - percent_y) / 2),
Constraint::Percentage(percent_y),
Constraint::Percentage((100 - percent_y) / 2),
]
.as_ref(),
)
.split(r);
Layout::default()
.direction(Direction::Horizontal)
.constraints(
[
Constraint::Percentage((100 - percent_x) / 2),
Constraint::Percentage(percent_x),
Constraint::Percentage((100 - percent_x) / 2),
]
.as_ref(),
)
.split(popup_layout[1])[1]
}
