High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I define a custom frame in a WoW addon XML file?▼

To define a custom frame in a WoW addon, use the <Frame> element within the <Ui> schema, setting attributes and child elements like <Anchors> and <Layers> to control its layout, textures, and inheritance.

What XML elements are available for creating textures and text in WoW UI development?▼

WoW UI XML development uses the <Texture> element for graphical layers and the <FontString> element for rendering text. Both inherit from <LayoutFrame> and support attributes for anchors, size, and layering within frames.

How does widget inheritance work in World of Warcraft addon XML?▼

Widget inheritance in WoW addon XML allows a <Frame> or <LayoutFrame> to derive properties from a parent element using the 'inherits' attribute, automatically applying the parent's size, anchors, scripts, and child elements to the new widget.

Can I define animations for UI frames using the WoW XML schema?▼

Yes, the WoW XML schema supports animations through the <AnimationGroup> element, which contains child animation elements that modify textures, frames, or rotation over time to create dynamic UI effects in addons.

What is the correct XML schema structure for a WoW addon UI file?▼

The correct XML schema structure for a WoW addon UI file starts with the root <Ui> element, which contains child <Frame>, <Texture>, and <FontString> elements organized hierarchically to define the visual layout and widget behavior.

Why are my WoW addon frames not displaying correctly despite valid XML syntax?▼

WoW addon frames may fail to display correctly if their <LayoutFrame> hierarchy is broken, anchors conflict, or required attributes are missing from elements like <Texture> or <Frame>. Validate your XML schema structure against the FrameXML reference.
