Struct DialogBuilder 

pub struct DialogBuilder {
    view_id: ViewId,
    title: String,
    buttons: Vec<(String, Event)>,
}

Builder for constructing a Dialog with custom buttons and message.

Use Dialog::builder to create a new builder, then chain calls to add_button to define the buttons, and finally call build to create the dialog.

Example

use cadmus_core::view::dialog::Dialog;
use cadmus_core::view::{Event, ViewId};

// Note: In actual use, `context` is provided by the application.
// Dialog::builder requires a properly initialized Context with
// Display and Fonts, so we show the API pattern here.
let dialog = Dialog::builder(ViewId::AboutDialog, "Are you sure?".to_string())
    .add_button("Cancel", Event::Close(ViewId::AboutDialog))
    .add_button("Confirm", Event::Validate)
    .build(&mut context);

Fields

view_id: ViewId

title: String

buttons: Vec<(String, Event)>

Implementations

impl DialogBuilder

fn new(view_id: ViewId, title: String) -> Self

pub fn build(self, context: &mut Context) -> Dialog

Build the dialog with the configured title and buttons.

Calculates the dialog layout, creates label and button views, and centers the dialog on the display.

Arguments

• context - The rendering context, used for font metrics and display dimensions
