Detailed Description
Contains all the knowledge about how to draw graphical object onto any particular output device.
This knowledge is held outside the individual graphical objects so that alternative output devices may be used, and so that the graphical objects themselves to not contain drawing routines. Drawing routines in the objects cause problems with usages of the objects as simple container objects in DLL/DSOs. PAINTER is an abstract layer because every module (pcbnew, eeschema, etc.) has to draw different kinds of objects.
Constructor & Destructor Documentation
◆ PAINTER()
| PAINTER::PAINTER | ( | GAL * | aGal | ) |
Initialize this object for painting on any of the polymorphic GRAPHICS_ABSTRACTION_LAYER* derivatives.
- Parameters
-
aGal is a pointer to a polymorphic GAL device on which to draw (i.e. Cairo, OpenGL, wxDC). No ownership is given to this PAINTER of aGal.

Member Function Documentation
◆ Draw()
|
pure virtual |
Takes an instance of VIEW_ITEM and passes it to a function that knows how to draw the item.
- Parameters
-
aItem is an item to be drawn. aLayer tells which layer is currently rendered so that draw functions may know what to draw (eg. for pads there are separate layers for holes, because they have other dimensions then the pad itself.
Implemented in ZONE_PAINTER, KIGFX::SCH_PAINTER, KIGFX::DS_PAINTER, KIGFX::GERBVIEW_PAINTER, and KIGFX::PCB_PAINTER.
Referenced by KIGFX::VIEW::draw(), KIGFX::VIEW::updateItemGeometry(), and KIGFX::VIEW_GROUP::ViewDraw().
◆ GetSettings()
|
pure virtual |
Return a pointer to current settings that are going to be used when drawing items.
- Returns
- Current rendering settings.
Implemented in KIGFX::SCH_PAINTER, KIGFX::GERBVIEW_PAINTER, KIGFX::DS_PAINTER, and KIGFX::PCB_PAINTER.
