Widget API

Widgets are graphical elements created in Lua with or via XML. Widget objects can be extended with templates, mixins and intrinsics. The user interface may be inspected with, and development addons like DevTool and Spew.

PlayerModel is officially documented as.

In patch 10.0.2 any addons that are creating GameTooltip frames should now ensure they inherit GameTooltipTemplate. This template has been updated to include the new GameTooltipDataMixin mixin, which provides automatic updates of tooltip contents from the event as well as a subset of backwards-compatible methods for retrieving or populating tooltip contents from the new C_TooltipInfo APIs.

These widget types have yet to be documented on the wiki. <!-- == UIObject ==

AnimationGroups (inherits from ParentedObject and ScriptObject, created with ) control how various animations are actually applied to a region.

• AnimationGroup:CreateAnimation( animationType, [name[,inheritsFrom]] ) - Create and return an Animation as a child of this group.
• AnimationGroup:Finish - Notify this group to stop playing once the current loop cycle is done. Does nothing if this group is not playing.
• AnimationGroup:GetAnimations
• AnimationGroup:GetDuration - Gets the total duration across all child Animations that the group will take to complete one loop cycle.
• AnimationGroup:GetLoopState - Gets the current loop state of the group. Output is [NONE, FORWARD, or REVERSE].
• AnimationGroup:GetLooping - Gets the type of looping for the group.
• AnimationGroup:GetProgress - Returns the progress of this animation as a unit value [0,1].
• AnimationGroup:IsDone - Returns true if the group has finished playing.
• AnimationGroup:IsPaused - Returns true if the group is paused.

This is an affine transformation that scales a parent Region about an origin. The scale can be non-uniform.
