VLine

Represent a vertical line:

To create a vertical line use VLine::new method (with 2 parameters: a layout and a set of flags). The flags let you choose if it is a double line.

let a = VLine::new(Layout::new("x:1,y:1,h:10"), Flags::None);
let b = VLine::new(Layout::new("x:3,y:1,h:20"), Flags::DoubleLine);

or the macro vline!

let hl1 = vline!("x:1,y:1,h:10");
let hl2 = vline!("x:3,y:1,h:20,flags:DoubleLine");

A vertical line supports all common parameters (as they are described in Instantiate via Macros section). Besides them, the following named parameters are also accepted:

Where the flags are defined as follows:

• vline::Flags::DoubleLine or DoubleLine (for macro initialization) - this will draw a double line instead of a single one.

Events

A vertical line emits no events.

Methods

A vertical line has no aditional methods.

Key association

A vertical line does not receive any input and as such it has no key associated with it.

Example

The following code creates a window with a vertical line.

use appcui::prelude::*;

fn main() -> Result<(), appcui::system::Error> {
    let mut app = App::new().build()?;
    let mut w = Window::new("Title", Layout::new("d:c,w:40,h:20"), window::Flags::None);
    
    w.add(VLine::new(Layout::new("x:3,y:1,h:15"), vline::Flags::DoubleLine));
    app.add_window(w);
    app.run();
    Ok(())
}
