[−][src]Struct druid::UpdateCtx

pub struct UpdateCtx<'a> { /* fields omitted */ }

A mutable context provided to data update methods of widgets.

Widgets should call request_paint whenever a data change causes a change in the widget's appearance, to schedule a repaint.

Methods

impl<'a> UpdateCtx<'a>[src]

pub fn invalidate(&mut self)[src]

Deprecated since 0.5.0:

use request_paint instead

pub fn request_paint(&mut self)[src]

Request a paint pass.

pub fn request_layout(&mut self)[src]

Request layout.

See EventCtx::request_layout for more information.

pub fn children_changed(&mut self)[src]

Indicate that your children have changed.

Widgets must call this method after adding a new child.

pub fn text(&mut self) -> Text[src]

Get an object which can create text layouts.

pub fn window(&self) -> &WindowHandle[src]
