Struct druid::widget::Tabs

pub struct Tabs<TP: TabsPolicy> { /* fields omitted */ }

A tabs widget.

The tabs can be provided up front, using Tabs::new() and add_tab()/with_tab().

Or, the tabs can be derived from the input data by implementing TabsPolicy, and providing it to Tabs::from_policy()

use druid::widget::{Tabs, Label, WidgetExt};
use druid::{Data, Lens};

#[derive(Data, Clone, Lens)]
struct AppState{
    name: String
}

let tabs = Tabs::new()
    .with_tab("Connection", Label::new("Connection information"))
    .with_tab("Proxy", Label::new("Proxy settings"))
    .lens(AppState::name);

Implementations

impl<T: Data> Tabs<StaticTabs<T>>

pub fn new() -> Self

Create a new Tabs widget, using the static tabs policy. Use with_tab or add_tab to configure the set of tabs available.

impl<TP: TabsPolicy> Tabs<TP>

pub fn for_policy(tabs: TP) -> Self

Create a Tabs widget using the provided policy. This is useful for tabs derived from data.

pub fn with_axis(self, axis: Axis) -> Self

Lay out the tab bar along the provided axis.

pub fn with_edge(self, edge: TabsEdge) -> Self

Put the tab bar on the specified edge of the cross axis.

pub fn with_transition(self, transition: TabsTransition) -> Self

Use the provided transition when tabs change

pub fn with_tab(
    self,
    name: impl Into<LabelText<TP::Input>>,
    child: impl Widget<TP::Input> + 'static
) -> Tabs<TP> where
    TP: AddTab, 

Available when the policy implements AddTab - e.g StaticTabs. Return this Tabs widget with the named tab added.

pub fn add_tab(
    &mut self,
    name: impl Into<LabelText<TP::Input>>,
    child: impl Widget<TP::Input> + 'static
) where
    TP: AddTab, 

Available when the policy implements AddTab - e.g StaticTabs. Return this Tabs widget with the named tab added.
