BCGControlBar Pro for MFC

Detailed Description

The CBCGPBaseVisualObject implements basic behavior of a "visual object". A "visual object" is a kind of windowless control, which can be displayed on any window inside a specified rectangle (CBCGPBaseVisualObject::SetRect).

All Gauges and Charts are "visual objects" and have a number of common properties.

The following features are automatically enabled for any "visual object" (e.g. a class derived from CBCGPBaseVisualObject):

  • Ability to reside in container. A container manages a layout and Z-order of visual objects.
  • Export to image, file or clipboard.
  • "Dirty" flag - invalidation and redraw on demand.
  • Animation managed at the base level.
  • Edit mode. In "edit mode" a visual object can be moved or resized. Tracking rectangle is drawn automatically by the library.
  • Image cache. The content of visual object is stored as an image, which can be redrawn much faster than it would be done with the regular drawing logic.
