Panel

Represent a panel (a container that can have multiple children):

To create a panel use Panel::new method (with 3 parameters: a title, a layout and a type).

let b = Panel::new("My panel", Layout::new("x:10,y:5,w:15"), panel::Type::Border);

or the macro panel!

let p1 = panel!("caption='a panel',x:10,y:5,w:15");
let p2 = panel!("MyPanel,x:10,y:5,w:15,type:Border");

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

Parameter name	Type	Positional parameter	Purpose
`title` or `text` or `caption`	String	Yes (first postional parameter)	The title of the panel
`type`	String	No	Panel type. If not provided, Border type is considered as default

A pabel supports the following types:

panel::Type::Border or border (for macro initialization) - this will create a panel surrounded by a border (with the title left allined).
panel::Type::Window or window (for macro initialization) - this will create a panel surrounded by a border (with the title centered allined).
panel::Type::Page or page (for macro initialization) - this will create a panel without any border or title
panel::Type::TopBar or topbar (for macro initialization) - this will create a panel with a top bar and centered titled

Events

A panel emits no events.

Methods

Besides the Common methods for all Controls a button also has the following aditional methods:

Method	Purpose
`set_title(...)`	Set the new title of the panel
`title()`	Returns the current title of the panel
`panel_type()`	Returns type of the panel
`add(...)`	Adds a new control as a child for the panel. It returns a handle for the new control or `Handle::None` if the control was not added

Key association

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

Example

The following code creates a panel with the title Options.

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:10"), window::Flags::None);
    w.add(Panel::new("Options", Layout::new("l:1,t:1,r:1,b:2"),panel::Type::Border));
    app.add_window(w);
    app.run();
    Ok(())
}
