Expand description

Base trait of all components. Every grx component is a ComponentExt.

Required Methods§

Source

fn visible(&self) -> bool

Whether this component is visible or not.

Source

fn height(&self) -> i32

The actual height of the component

Source

fn width(&self) -> i32

The actual width of the component

Source

fn set_visible(&self, visible: bool)

Set the visibility of this component.

Source

fn add_class(&self, class: &str)

Add a CSS class to this component.

Source

fn classes(&self) -> Vec<String>

Get the list of CSS classes of this component.

Source

fn remove_class(&self, class: &str)

Remove a CSS from this component.

Source

fn set_styles(&self, styles: Vec<Style>)

Set the crate::styles::Styles of this component.

This does not remove styles that are already set but not included in the given vec.

Source

fn inner(&self) -> Rc<dyn Any>

Get the inner component (may be platform specific thing).

Source

fn props(&self) -> &dyn ExtendingProps

Get the props of this component.

Source

fn annotations(&self) -> Ref<'_, Annotations>

Get the annotations of this component.

Source

fn annotations_mut(&self) -> RefMut<'_, Annotations>

Get a mutable ref to the annotations of this component.

Source

fn try_annotations_mut(&self) -> Result<RefMut<'_, Annotations>, BorrowMutError>

Like annotations_mut but with a Result. Errors when the annotations can not be borrowed mutably.

Source

fn children(&self) -> Ref<'_, Vec<Component>>

Get the children of this component.

Source

fn children_mut(&self) -> RefMut<'_, Vec<Component>>

Get a mutable ref to the children of this component.

Source

fn into_any(self: Rc<Self>) -> Rc<dyn Any>

Cast to any.
