Module: Teek::UI::OverlayAnchors Private

Defined in:

lib/teek/ui/overlay_anchors.rb

Overview

This module is part of a private API. You should avoid using this module if possible, as it may be removed or be changed in the future.

ui.overlay's at: vocabulary - corners, center, and the four edge midpoints, spelled in plain English rather than Tk's own compass anchors (nw/n/ne/w/center/e/sw/s/se) - the same litmus test every other DSL name follows (decoding one should never need Tk knowledge). Each maps to place's own -relx/-rely/-anchor, needed both to validate at: (WidgetDSL#overlay) and to actually place the widget (Realizer#place_overlay) - one shared table so the two can never drift out of sync with each other.
