New classes:
- VIEW - represents view that is seen by user, takes care of layer ordering & visibility and how it is displayed (which location, how much zoomed, etc.)
- VIEW_ITEM - Base class for every item that can be displayed on VIEW (the biggest change is that now it may be necessary to override ViewBBox & ViewGetLayers method for derived classes).
- EDA_DRAW_PANEL_GAL - Inherits after EDA_DRAW_PANEL, displays VIEW output, right now it is not editable (in opposite to usual EDA_DRAW_PANEL).
- GAL/OPENGL_GAL/CAIRO_GAL - Base Graphics Abstraction Layer class + two different flavours (Cairo is not fully supported yet), that offers methods to draw primitives using different libraries.
- WX_VIEW_CONTROLS - Controller for VIEW, handles user events, allows zooming, panning, etc.
- PAINTER/PCB_PAINTER - Classes that uses GAL interface to draw items (as you may have already guessed - PCB_PAINTER is a class for drawing PCB specific object, PAINTER is an abstract class). Its methods are invoked by VIEW, when an item has to be drawn. To display a new type of item - you need to implement draw(ITEM_TYPE*) method that draws it using GAL methods.
- STROKE_FONT - Implements stroke font drawing using GAL methods.
Most important changes to Kicad original code:
* EDA_ITEM now inherits from VIEW_ITEM, which is a base class for all drawable objects.
* EDA_DRAW_FRAME contains both usual EDA_DRAW_PANEL and new EDA_DRAW_PANEL_GAL, that can be switched anytime.
* There are some new layers for displaying multilayer pads, vias & pads holes (these are not shown yet on the right sidebar in pcbnew)
* Display order of layers is different than in previous versions (if you are curious - you may check m_galLayerOrder@pcbnew/basepcbframe.cpp). Preserving usual order would result in not very natural display, such as showing silkscreen texts on the bottom.
* Introduced new hotkey (Alt+F12) and new menu option (View->Switch canvas) for switching canvas during runtime.
* Some of classes (mostly derived from BOARD_ITEM) now includes ViewBBox & ViewGetLayers methods.
* Removed tools/class_painter.h, as now it is extended and included in source code.
Build changes:
* GAL-based rendering option is turned on by a new compilation CMake option KICAD_GAL.
* When compiling with CMake option KICAD_GAL=ON, GLEW and Cairo libraries are required.
* GAL-related code is compiled into a static library (common/libgal).
* Build with KICAD_GAL=OFF should not need any new libraries and should come out as a standard version of Kicad
Currently most of items in pcbnew can be displayed using OpenGL (to be done are DIMENSIONS and MARKERS).
More details about GAL can be found in: http://www.ohwr.org/attachments/1884/view-spec.pdf
* Complete encapsulation of the MODULE class.
* Complete encapsulation of the EDA_TEXT class.
* Encapsulate most of the ZONE_CONTAINER class.
* Add pcbcommon library as a dependency for reSWIGging the scripting
support. This should cover most dependency cases.
* Improve MSG_PANEL_ITEM to handle message panel information.
* Create containers for passing message panel items between objects and
the message panel.
* Rename EDA_ITEM::DisplayInfo to EDA_ITEM::GetMsgPanelInfo.
* Remove all direct manipulation of EDA_DRAW_FRAME from all objects derived
from EDA_ITEM.
* Move board item object Format() functions into PCB_IO object.
* Change file format to use layer names instead of numbers.
* Change file extension to kicad_pcb.
* Move EDA_TEXT object into separate header and source file.
* Compile EDA_TEXT class separately for BOARD_ITEM and SCH_ITEM units.
* Compile PAGE_INFO class separately for BOARD_ITEM and SCH_ITEM units.
* Minor formatting tweaks to Pcbnew s-expression file.
* Move internal unit formatting functions into BOARD_ITEM and SCH_ITEM.
* Add s-expression Format() function to all objects derived from
BOARD_ITEM.
* Add s-expression Format() function to base objects as required.
* Add functions to convert coordinates from base internal units
(nanometers) to millimeter string for writing to s-expression
file.
* Add temporary dummy conversion functions to prevent link errors
until schematic and board object and action code can be separated
into DSO/DLL.
* Add CMake build option to build Pcbnew with nanometer internal
units.
* BLOCK_SELECTOR class is not longer derived from EDA_ITEM.
* Encapsulate BLOCK_SELECTOR class member variables and add access methods.
* Move HandleBlockBegin() function from block_commande.cpp to drawframe.cpp.
* Remove virtual methods from top level derived objects per future
coding policy change.
* Remove Doxygen copydoc statement from objects derived from EDA_ITEM
since the comments are automatically copied to the derived object.
* Removed copy and pasted Doxygen comments from objects derived from
EDA_ITEM.
* All objects derived from EDA_ITEM now have consistent hit test method
definitions.
* Remove double function calls from all classes derived from SCH_ITEM.
* Lots of Doxygen comment fixes.
* Remove unnecessary copy constructors from board and module library
objects.
* Add doClone() method to board and library objects.
* Add comment to class definitions where the default copy constructor
generated by the compiler was adequate.
* Replace copy method with clone method where applicable.
* Remove DuplicateStruct() function.
* Remove track object copy function.
* Removed Pcb_Frame argument from BOARD() constructor, since it precludes
having a BOARD being edited by more than one editor, it was a bad design.
And this meant removing m_PcbFrame from BOARD.
* removed BOARD::SetWindowFrame(), and BOARD::m_PcbFrame
* Removed the global BOARD_DESIGN_SETTINGS which was in class_board.cpp
* added BOARD_DESIGN_SETTINGS to the BOARD class, a full instance
* a couple dialogs now only change BOARD_DESIGN_SETTINGS when OK is pressed,
such as dialog_mask_clearance, dialog_drc, etc.
* Removed common/pcbcommon.cpp's int g_CurrentVersionPCB = 1 and replaced it
with build_version.h's #define BOARD_FILE_VERSION, although there may be a
better place for this constant.
* Made the public functions in PARAM_CFG_ARRAY be type const.
void SaveParam(..) const and void ReadParam(..) const
* PARAM_CFG_BASE now has virtual destructor since we have various way of
destroying the derived class and boost::ptr_vector must be told about this.
* Pass const PARAM_CFG_ARRAY& instead of PARAM_CFG_ARRAY so that we can use
an automatic PARAM_CFG_ARRAY which is on the stack.\
* PCB_EDIT_FRAME::GetProjectFileParameters() may no longer cache the array,
since it has to access the current BOARD and the BOARD can change.
Remember BOARD_DESIGN_SETTINGS are now in the BOARD.
* Made the m_BoundingBox member private, this was a brutally hard task,
and indicative of the lack of commitment to accessors and object oriented
design on the part of KiCad developers. We must do better.
Added BOARD::GetBoundingBox, SetBoundingBox(), ComputeBoundingBox().
* Added PCB_BASE_FRAME::GetBoardBoundingBox() which calls BOARD::ComputeBoundingBox()
the GetPosition() and SetPosition() changes. It also starts towards making m_Orientation
and m_Thickness fields private with accessors, but does not complete this latter goal.
* All header files used to create the PCB common library now compile as
stand alone code. This prevents the need to define them in a specific
order to make source code compile properly. It should also now be
possible to relocate the source code to build the common PCB library
to a separate folder.
* Move schematic wire and bus break code into schematic screen object.
* Move schematic test for dangling ends into schematic screen object.
* Remove left over debugging output in schematic screen object.
* Remove unused file eeschema/cleanup.cpp.
* Fix bug in schematic line object hit test algorithm.
* Fix a string concatenation compile error added in r2752.
* Rename class WinEDA_BasicFrame to EDA_BASE_FRAME.
* Rename class WinEDA_DrawFrame to EDA_DRAW_FRAME.
* Rename class WinEDA_DrawPanel to EDA_DRAW_PANEL.
