Overview

Interface for a widget which knows it is being rendered inside an arc, and will draw itself accordingly. Any widget implementing this interface will receive the full-sized canvas, pre-rotated, in its draw call.

Summary

Methods

Returns the sweep angle that this widget is drawn with.

Set the sweep angle that this widget is drawn with. This is only called during layout, and only if the ArcLayout.LayoutParams.mWeight is non-zero. Note your widget will need to handle alignment.

Returns the thickness of this widget inside the arc.

Check whether the widget contains invalid attributes as a child of ArcLayout, throwing a Exception if something is wrong. This is important for widgets that can be both standalone or used inside an ArcLayout, some parameters used when the widget is standalone doesn't make sense when the widget is inside an ArcLayout.

Return true when the given point is in the clickable area of the child widget. In particular, the coordinates should be considered as if the child was drawn centered at the default angle (12 o clock).
