|
* The WS_DATA_ITEM_* classes define the basic shapes of a page layout (frame references
|
|
* and title block). The list of these items is stored in a WS_DATA_MODEL instance.
|
|
*
|
|
* These items cannot be drawn or plotetd "as is". They must be converted to WS_DRAW_*
|
|
* types. When building the draw list:
|
|
* - the WS_DATA_MODEL is used to create a WS_DRAW_ITEM_LIST
|
|
* - coordinates are converted to draw/plot coordinates.
|
|
* - texts are expanded if they contain format symbols.
|
|
* - items with m_RepeatCount > 1 are created m_RepeatCount times.
|
|
*
|
|
* The WS_DATA_MODEL is created only once.
|
|
* The WS_DRAW_ITEM_*s are created and maintained by the PlEditor, but are created each time
|
|
* they're needed for drawing by the clients (Eeschema, Pcbnew, etc.)
|
|
*
|
|
* The WS_DATA_MODEL instance is created from a S expression which describes the page
|
|
* layout (can be the default page layout or a custom file). This format is also used
|
|
* for undo/redo storage (wrapped in a WS_PROXY_UNDO_ITEM).
