Struct ResizeHandleContext

Source

pub struct ResizeHandleContext { /* private fields */ }

Expand description

What a ResizeHandleRenderer is told about the handle it is drawing.

The hit area, the cursor and the drag itself stay with the handle; a renderer only supplies what is painted inside it.

Implementations§

Source §

impl ResizeHandleContext

Source

pub fn axis(&self) -> Axis

The axis the handle resizes along: Horizontal for a vertical divider between two side-by-side panels.

Source

pub fn edge(&self) -> Option<HandleEdge>

The edge of its container this handle hugs, or None for a handle straddling the boundary it resizes.

A hugging handle’s line is the container’s outermost pixel, so anything a renderer centres on it crosses the boundary; see HandleEdge for what the container does with that.

Source

pub fn is_active(&self) -> bool

Whether the pointer currently owns this handle.

Source

pub fn state(&self) -> ResizeHandleState

How far the pointer has gone with this handle.
