1 CAPI Reference Entries
pinboard-layoutprovides two very useful pieces of functionality for displaying CAPI windows. Firstly it is a layout that allows its children to be positioned anywhere within itself (like a pinboard). Secondly it supports
pinboard-objectswhich are rectangular areas within the layout which have size and drawing functionality.
pinboard-layoutlays out its children, it positions them at the x and y specified as hints (using
:y), and sizes them to their minimum size (which can be specified using
:max-width). The pinboard layout itself has a minimum size of one pixel by one pixel which is not affected by the size of its children. If you need the sizing capabilities, then use the class
simple-pinboard-layoutwhich surrounds a single child, and adopts the size constraints of that child.
draw-pinboard-objecton these objects in the order that they are specified in the layout description. This means that if two pinboard objects overlap, the later one in the layout description will be on top of the other one.
