Struct TitleBar 

pub struct TitleBar { /* private fields */ }

A title bar drawn by the app: what comes first, the title, the actions and the buttons of the window. A button shows only when it has a handler. A double click on the bar does the same as the maximize button.

It draws and calls back, and that is all. What the handlers do to the window is up to the app. It cannot drag the window nor hide the frame the system draws, because those belong to the platform layer, which offers neither yet: for now the system’s own bar stays above it.

use ravenrs_widgets::{IconButton, IconName, TitleBar, Ui};

let bar = TitleBar::new("Report.pdf")
    .action(IconButton::new(IconName::Search).label("Search"))
    .on_minimize(|| {})
    .on_maximize(|| {})
    .on_close(|| {});
let mut ui = Ui::new(bar, ravenrs_style::Theme::raven_dark());
ui.update();

Implementations

impl TitleBar

pub fn new(title: impl Into<String>) -> Self

A bar with this title and no buttons.

pub fn leading(self, view: impl View + 'static) -> Self

Any view before the title, such as an icon or a menu.

pub fn action(self, view: impl View + 'static) -> Self

Appends a view to the area between the title and the window’s buttons.

pub fn on_minimize(self, handler: impl Fn() + 'static) -> Self

Shows the minimize button, which runs handler.

pub fn on_maximize(self, handler: impl Fn() + 'static) -> Self

Shows the maximize button, which runs handler, as a double click on the bar does.

pub fn on_close(self, handler: impl Fn() + 'static) -> Self

Shows the close button, which runs handler.

pub fn on_context_menu(self, handler: impl Fn(Point) + 'static) -> Self

Called with the pointer’s place on a right click on the bar, for a menu of the window.

pub fn maximized(self, maximized: bool) -> Self

The window is maximized: the maximize button shows and says that it restores.

pub fn active(self, active: bool) -> Self

Whether the window has the keyboard (it does by default). Without it the bar goes quiet, which is how to tell which of two windows side by side is listening.
