Implementations

impl Panel

pub fn new_builder(top_level: Widget) -> PanelBuilder

pub fn empty(ctx: &mut EventCtx<'_>) -> Panel

Returns an empty panel. event and draw will have no effect.

fn update_container_dims_for_canvas_dims(&mut self, canvas_dims: ScreenDims)

fn recompute_scrollbar_layout(&mut self, ctx: &EventCtx<'_>)

fn recompute_layout(&mut self, ctx: &EventCtx<'_>, recompute_bg: bool)

fn invalidate_flexbox(&mut self)

fn compute_flexbox(&self) -> (Taffy, Vec<Node>, ScreenDims)

fn recompute_layout_if_needed(&mut self, ctx: &EventCtx<'_>, recompute_bg: bool)

fn scroll_offset(&self) -> (f64, f64)

fn update_scroll_sliders( &mut self, ctx: &EventCtx<'_>, offset: (f64, f64), ) -> bool

fn set_scroll_offset(&mut self, ctx: &EventCtx<'_>, offset: (f64, f64))

pub fn event(&mut self, ctx: &mut EventCtx<'_>) -> Outcome

pub fn draw(&self, g: &mut GfxCtx<'_>)

pub fn get_all_click_actions(&self) -> HashSet<String>

pub fn restore(&mut self, ctx: &mut EventCtx<'_>, prev: &Panel)

pub fn restore_scroll(&mut self, ctx: &mut EventCtx<'_>, prev: &Panel)

pub fn scroll_to_member(&mut self, ctx: &EventCtx<'_>, name: String)

pub fn has_widget(&self, name: &str) -> bool

pub fn slider(&self, name: &str) -> &Slider

pub fn slider_mut(&mut self, name: &str) -> &mut Slider

pub fn take_menu_choice<T: 'static>(&mut self, name: &str) -> T

pub fn is_checked(&self, name: &str) -> bool

pub fn maybe_is_checked(&self, name: &str) -> Option<bool>

pub fn set_checked(&mut self, name: &str, on_off: bool)

pub fn text_box(&self, name: &str) -> String

pub fn spinner<T: 'static + SpinnerValue>(&self, name: &str) -> T

pub fn modify_spinner<T: 'static + SpinnerValue>( &mut self, ctx: &EventCtx<'_>, name: &str, delta: T, )

pub fn persistent_split_value<T: 'static + PartialEq + Clone>( &self, name: &str, ) -> T

pub fn autocomplete_done<T: 'static + Clone>( &mut self, name: &str, ) -> Option<Vec<T>>

Consumes the autocomplete widget. It’s fine if the panel survives past this event; the autocomplete just needs to be interacted with again to produce more values.

pub fn stash<T: 'static>(&self, name: &str) -> Rc<RefCell<T>>

Grab a stashed value, with the ability to pass it around and modify it.

pub fn clone_stashed<T: 'static + Clone>(&self, name: &str) -> T

Grab a stashed value and clone it.

pub fn is_button_enabled(&self, name: &str) -> bool

pub fn maybe_find_widget(&self, name: &str) -> Option<&Widget>

pub fn maybe_find<T: WidgetImpl>(&self, name: &str) -> Option<&T>

pub fn find<T: WidgetImpl>(&self, name: &str) -> &T

pub(crate) fn swap_inner_content( &mut self, ctx: &EventCtx<'_>, container_name: &str, new_inner_content: &mut Widget, )

Swap the inner content of a container widget with new_inner_content.

pub fn rect_of(&self, name: &str) -> &ScreenRectangle

pub fn panel_dims(&self) -> ScreenDims

pub fn align(&mut self, horiz: HorizontalAlignment, vert: VerticalAlignment)

pub fn replace(&mut self, ctx: &mut EventCtx<'_>, id: &str, new: Widget)

All margins/padding/etc from the previous widget are retained. The ID is set on the new widget; no need to do that yourself.

pub fn take(&mut self, id: &str) -> Widget

Removes a widget from the panel. Does not recalculate layout!

pub fn clicked_outside(&self, ctx: &mut EventCtx<'_>) -> bool

pub fn currently_hovering(&self) -> Option<&String>
