Struct cursive::views::Dialog

pub struct Dialog { /* fields omitted */ }

Popup-like view with a main content, and optional buttons under it.

Examples

let dialog = Dialog::around(TextView::new("Hello!"))
                    .button("Ok", |s| s.quit());

Methods

impl Dialog

pub fn new() -> Self

Creates a new Dialog with empty content.

You should probably call content() next.

pub fn around<V: View + 'static>(view: V) -> Self

Creates a new Dialog with the given content.

pub fn content<V: View + 'static>(self, view: V) -> Self

Sets the content for this dialog.

Chainable variant.

pub fn get_content(&self) -> &dyn View

Gets the content of this dialog.

use cursive::views::{Dialog, TextView};
let dialog = Dialog::around(TextView::new("Hello!"));
let text_view: &TextView = dialog
    .get_content()
    .as_any()
    .downcast_ref::<TextView>()
    .unwrap();
assert_eq!(text_view.get_content().source(), "Hello!");

pub fn get_content_mut(&mut self) -> &mut dyn View

Gets mutable access to the content.

pub fn set_content<V: View + 'static>(&mut self, view: V)

Sets the content for this dialog.

Previous content will be dropped.

pub fn text<S: Into<String>>(text: S) -> Self

Convenient method to create a dialog with a simple text content.

pub fn info<S: Into<String>>(text: S) -> Self

Convenient method to create an infobox.

It will contain the given text and a Ok dismiss button.

pub fn button<F, S: Into<String>>(self, label: S, cb: F) -> Self where
    F: 'static + Fn(&mut Cursive), 

Adds a button to the dialog with the given label and callback.

Consumes and returns self for easy chaining.

pub fn add_button<F, S: Into<String>>(&mut self, label: S, cb: F) where
    F: 'static + Fn(&mut Cursive), 

Adds a button to the dialog with the given label and callback.

pub fn buttons_len(&self) -> usize

Returns the number of buttons on this dialog.

pub fn clear_buttons(&mut self)

Removes any button from self.

pub fn remove_button(&mut self, i: usize)

Removes a button from this dialog.

Panics

Panics if i >= self.buttons_len().

pub fn h_align(self, h: HAlign) -> Self

Sets the horizontal alignment for the buttons, if any.

Only works if the buttons are as a row at the bottom of the dialog.

pub fn dismiss_button<S: Into<String>>(self, label: S) -> Self

Shortcut method to add a button that will dismiss the dialog.

pub fn title<S: Into<String>>(self, label: S) -> Self

Sets the title of the dialog.

If not empty, it will be visible at the top.

pub fn set_title<S: Into<String>>(&mut self, label: S)

Sets the title of the dialog.

pub fn title_position(self, align: HAlign) -> Self

Sets the horizontal position of the title in the dialog. The default position is HAlign::Center

pub fn set_title_position(&mut self, align: HAlign)

Sets the horizontal position of the title in the dialog. The default position is HAlign::Center

pub fn padding<T: Into<Margins>>(self, padding: T) -> Self

Sets the padding in the dialog (around content and buttons).

pub fn padding_top(self, padding: usize) -> Self

Sets the top padding in the dialog (under the title).

pub fn padding_bottom(self, padding: usize) -> Self

Sets the bottom padding in the dialog (under buttons).

pub fn padding_left(self, padding: usize) -> Self

Sets the left padding in the dialog.

pub fn padding_right(self, padding: usize) -> Self

Sets the right padding in the dialog.

pub fn buttons_mut(&mut self) -> impl Iterator<Item = &mut Button>

Returns an iterator on this buttons for this dialog.

pub fn focus(&self) -> DialogFocus

Returns currently focused element

Trait Implementations

impl View for Dialog

fn draw(&self, printer: &Printer)

Draws the view with the given printer (includes bounds) and focus.

fn required_size(&mut self, req: Vec2) -> Vec2

Returns the minimum size the view requires with the given restrictions.

fn layout(&mut self, size: Vec2)

Called once the size for this view has been decided.

fn on_event(&mut self, event: Event) -> EventResult

Called when an event is received (key press, mouse event, ...).

fn take_focus(&mut self, source: Direction) -> bool

This view is offered focus. Will it take it?

fn call_on_any<'a>(&mut self, selector: &Selector, callback: AnyCb<'a>)

Runs a closure on the view identified by the given selector.

fn focus_view(&mut self, selector: &Selector) -> Result<(), ()>

Moves the focus to the view identified by the given selector.

fn important_area(&self, _: Vec2) -> Rect

What part of the view is important and should be visible?

fn needs_relayout(&self) -> bool

Should return true if the view content changed since the last call to layout().

impl Default for Dialog

fn default() -> Self

Returns the "default value" for a type.
