Struct cushy::widgets::Resize

pub struct Resize {
    pub width: DimensionRange,
    pub height: DimensionRange,
    /* private fields */
}

Fields

width: DimensionRange

The range of allowed width for the child widget.

height: DimensionRange

The range of allowed height for the child widget.

Implementations

impl Resize

pub fn child(&self) -> &WidgetRef

Returns a reference to the child widget.

pub fn to<T>(size: Size<T>, child: impl MakeWidget) -> Self

where T: Into<DimensionRange>,

Resizes child to size.

pub fn from_width( width: impl Into<DimensionRange>, child: impl MakeWidget, ) -> Self

Resizes child’s width to width.

pub fn width(self, width: impl Into<DimensionRange>) -> Self

Resizes self to width.

width can be an any of:

• Dimension
• Px
• Lp
• A range of any fo the above.

pub fn height(self, height: impl Into<DimensionRange>) -> Self

Resizes self to height.

height can be an any of:

• Dimension
• Px
• Lp
• A range of any fo the above.

pub fn from_height( height: impl Into<DimensionRange>, child: impl MakeWidget, ) -> Self

Resizes child’s height to height.

Trait Implementations

impl Debug for Resize

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Returns the rectangle that the child widget should occupy given available_space.

fn summarize(&self, f: &mut Formatter<'_>) -> Result

Writes a summary of this widget into fmt.

fn redraw_background(&mut self, context: &mut GraphicsContext<'_, '_, '_, '_>)

Draws the background of the widget.

fn redraw_foreground(&mut self, context: &mut GraphicsContext<'_, '_, '_, '_>)

Draws the foreground of the widget.

Returns the adjusted contraints to use when laying out the child.

fn position_child( &mut self, size: Size<Px>, available_space: Size<ConstraintLimit>, context: &mut LayoutContext<'_, '_, '_, '_>, ) -> WrappedLayout

Returns the layout after positioning the child that occupies size.

fn background_color(&mut self, context: &WidgetContext<'_>) -> Option<Color>

Returns the background color to render behind the wrapped widget.

fn mounted(&mut self, context: &mut EventContext<'_>)

The widget has been mounted into a parent widget.

fn unmounted(&mut self, context: &mut EventContext<'_>)

The widget has been removed from its parent widget.

fn hit_test( &mut self, location: Point<Px>, context: &mut EventContext<'_>, ) -> bool

Returns true if this widget should respond to mouse input at location.

fn hover( &mut self, location: Point<Px>, context: &mut EventContext<'_>, ) -> Option<CursorIcon>

The widget is currently has a cursor hovering it at location.

fn unhover(&mut self, context: &mut EventContext<'_>)

The widget is no longer being hovered.

fn accept_focus(&mut self, context: &mut EventContext<'_>) -> bool

This widget has been targeted to be focused. If this function returns true, the widget will be focused. If false, Cushy will continue searching for another focus target.

fn advance_focus( &mut self, direction: VisualOrder, context: &mut EventContext<'_>, ) -> EventHandling

The widget should switch to the next focusable area within this widget, honoring direction in a consistent manner. Returning HANDLED will cause the search for the next focus widget stop.

fn focus(&mut self, context: &mut EventContext<'_>)

The widget has received focus for user input.

fn allow_blur(&mut self, context: &mut EventContext<'_>) -> bool

The widget is about to lose focus. Returning true allows the focus to switch away from this widget.

fn blur(&mut self, context: &mut EventContext<'_>)

The widget is no longer focused for user input.

fn activate(&mut self, context: &mut EventContext<'_>)

The widget has become the active widget.

fn deactivate(&mut self, context: &mut EventContext<'_>)

The widget is no longer active.

fn mouse_down( &mut self, location: Point<Px>, device_id: DeviceId, button: MouseButton, context: &mut EventContext<'_>, ) -> EventHandling

A mouse button event has occurred at location. Returns whether the event has been handled or not.

fn mouse_drag( &mut self, location: Point<Px>, device_id: DeviceId, button: MouseButton, context: &mut EventContext<'_>, )

A mouse button is being held down as the cursor is moved across the widget.

fn mouse_up( &mut self, location: Option<Point<Px>>, device_id: DeviceId, button: MouseButton, context: &mut EventContext<'_>, )

A mouse button is no longer being pressed.

fn keyboard_input( &mut self, device_id: DeviceId, input: KeyEvent, is_synthetic: bool, context: &mut EventContext<'_>, ) -> EventHandling
