Detailed Description

Class VIEW.

Holds a (potentially large) number of VIEW_ITEMs and renders them on a graphics device provided by the GAL. VIEWs can exist in two flavors:

  • dynamic - where items can be added, removed or changed anytime, intended for the main editing panel. Each VIEW_ITEM can be added to a single dynamic view.
  • static - where items are added once at the startup and are not linked with the VIEW. Foreseen for preview windows and printing. Items in a view are grouped in layers (not to be confused with Kicad's PCB layers). Each layer is identified by an integer number. Visibility and rendering order can be set individually for each of the layers. Future versions of the VIEW will also allow to assign different layers to different rendering targets, which will be composited at the final stage by the GAL. The VIEW class also provides fast methods for finding all visible objects that are within a given rectangular area, useful for object selection/hit testing.
