jean-pierre charras 9b3ff5af47 Fix a few I18N issues. 
Especially keywords should not be included in translated strings.

Mark Roszko c6e388db14 Implement an app progress indicator in the taskbar 
ADDED: Progress indicator in the taskbar

This adds a progress indicator to the Windows and macOS taskbar
icons to display the progress of some operations.

Note, this requires wxWidgets 3.1+

Jeff Young 02bf5d27df Fix crash when a DRC rule specifies an empty zone as a keepout. 2020-08-08 16:25:30 +01:00
Jeff Young db501c2002 Fix issue with doing DRC on a multi-layer zone. 
Testing for an intersection of layers between the zone and the
item (track in this case) isn't enough: we need to test for the
presence of the item on each layer of the zone.

Tomasz Wlostowski 89a953e039 Migrated GetEffectiveShape(s) to SHAPE_COMPOUND 2020-07-29 23:14:03 +02:00
Jeff Young 0fecb5f277 Be more explicit about string/character conversions. 
This *may* fix the bug where a layer name isn't displayed correctly
in the error dialog.  But probably not.
 2020-07-28 20:44:40 +01:00
Jeff Young bf445c1a95 Performance enhancements. 
1) cache pad polygon outlines
   huge improvement in connectivity performance and a decent
   improvement in DRC performance
2) don't pre-allocate CONTEXT stack
   significant improvement in DRC rule performance
2) don't keep re-encoding strings
   decent improvement in DRC rule performance
 2020-07-25 13:03:33 +01:00
Jeff Young f97c50bfde Give excluded DRC items their own layer. 
(And fix a bug with the new mulit-layer zones and rule-based keepouts
at the same time which prevented me from testing it.)

Fixes https://gitlab.com/kicad/code/kicad/issues/4954
 2020-07-24 01:28:25 +01:00
Jeff Young 6529e339a9 Don't store context in the uCode. (It's not thread-safe.) 
Although it does give some pretty funny results when filling zones.
 2020-07-23 22:21:13 +01:00

Jon Evans 12b4a55ae8 Port Eeschema to new project settings 
DRC/ERC error serialization changed to use explicit tokens
Old stored severities and ignored errors are discarded
 2020-07-02 22:08:54 -04:00
Jon Evans c0aa6965de Migrate PcbNew project settings to new framework 
Various architecture upgrades to support this.
Creating a BOARD now requires a valid PROJECT, which caused
some (mostly transparent) changes to the Python API internals.

ADDED: Project local settings file
CHANGED: Board design settings are no longer stored in PCB file
CHANGED: Net classes are no longer stored in PCB file
CHANGED: Importing board settings now reads boards, not just projects

 2020-07-02 22:08:54 -04:00

from all the SHAPE collision routines.

Fixes https://gitlab.com/kicad/code/kicad/issues/4774
 2020-07-02 17:09:15 +01:00

round and square pads the same.
 2020-07-01 16:57:00 +01:00
Jeff Young 40a72d9530 Add SH_RECT handling to 3D shape conversion.

Jon Evans 0d4ee39f75 CHANGED: Copper zones can be on more than one layer 
Fixes https://gitlab.com/kicad/code/kicad/-/issues/1963
 2020-06-28 08:52:37 -04:00
Jeff Young d01b29ab37 Cleanup pad geometry handling. 
There were a lot of plotters, exporters, etc. that were rolling their
own implementations.

This also introduces a lazily-built set of SHAPE objects for doing
collision detection and some forms of rendering (and later DRC).
 2020-06-22 22:28:37 +01:00

 2020-06-18 15:38:01 +01:00
Jeff Young a7703d1207 Cleanup Graphics to parallel Cleanup Tracks & Vias. 
This also allows for easier migration to DRAWSEGMENT::S_RECTs by
auto-converting 4 rectilinear lines to a rectangle.
 2020-06-17 18:44:39 +01:00
Jeff Young aeed8e6e2c Finish implementation of DRAWSEGMENT::C_RECT. 
It's currently only supported in the Footprint Editor.  It could be
easily added to the board editor (all the code is there), but the board
editor is a little short on room in the drawing tools toolbar.

2) Check pads against board edge.

3) Don't report vias as "Track too close to board edge".

Seth Hillbrand c4d853c1e8 SHAPE_LINE_CHAIN: Remove element access 
This is the first step to allowing non-segments in the line chain.
External routines cannot be allowed to change the line chain without
going through the internal routines.  To accomplish this, we remove the
Vertex() and Point() access routines and only leave the const versions.
Transformations are given for both points as well as the chain itself.

Seth Hillbrand 40309a17ef pcbnew: Check exact overlapping polygons 
Checks for polygon collisions in the outline when the polygon contains
two or more segments that exactly overlap.  This also places the DRC
marker at the location where the collision happens.

John Beard 8297ab24e4 DRC: Break out courtyard overlap function 
Introduce the concept of a DRC_PROVIDER which allows
to separate the various DRC functions to their own
areas. This allows, amongst other things, a slimmer core
DRC class, and allows DRC functions to be separately testable.

The courtyard DRCs (overlap, missing and malformed)
are the first victims, so instrumentation can be added to this function.

Add some unit tests on this DRC function, as well a few re-usable PCB-based
utility functions in a library (qa_pcbnew_utils) that could be shared between
unit tests and other utilities.

John Beard e6edc1b670 DRC: Make the marker factory a separate class 
This separates the "newMarker" functions from the DRC class. These
are moved to a new class, DRC_MARKER_FACTORY, which is now responsible for
constructing suitable markers from BOARD_ITEMS.

The reasons for this are:

1) Allow DRC related functions to access theese functions without having
   to bake these functions into the main DRC class.
2) Thereby simplify the DRC class interface
3) As DRC_MARKER is now a small class with public interfaces, it's
   possible to put unit tests on these functions.

The motivation here is to allow to start to split out pieces of DRC
into separate classes.
