- Not to be confused with Layering or Frame Level.
A layer (or DRAWLAYER[1]) orders each LayeredRegion within a Frame, affecting how they overlap. There are five named layers, in the order they are drawn (back to front):
- BACKGROUND
- BORDER
- ARTWORK
- OVERLAY
- HIGHLIGHT (see details)
Two widgets in the same layer may be further ordered using a sublayer (or textureSubLevel[2]) specified numerically from -8 to 7 (back to front).
Details[]
- When one frame is in front of another (according to its Frame Strata), all of its LayeredRegions will also be in front -- in otherwords, layers are part of each frame.
- Setting Frame:EnableMouse() causes HIGHLIGHT to show/hide as the cursor hovers the Frame.
- Transparent overlapping textures display different results depending on their relative ordering. For consistent results, use a blend mode of ADD or MOD on both textures.
Example[]
Construct a Texture inside the "ARTWORK" layer of a <Frame>.
<Frame>
<Layers>
<Layer level="ARTWORK">
<Texture />
</Layer>
</Layers>
</Frame>
