There are still a few more files that are compiled multiple times. I
plan to fix them as well, but first I want to send the first patches to
see if we all agree on the proposed solution.
Alternatively, there could be an abstract class to provide conversion
methods. If it is preferred, then we need to decide how to access its
instance (singleton, attach to KiFace, static object?)
Ultimately we can have a real common library for all apps (libkicommon?)
that could be compiled as a shared library. Such approach should reduce
*.kiface files size and linking time.
I'm new to the dev list and haven't looked at the issue you're dealing
with yet. However, I'm looking at an issue that may be related and we
may want to consider as you make your changes.
I want to accomplish two goals:
1. Allow the user to set the origin from which the location of all
objects is measured. Right now this is the upper left corner of
whatever Paper size and orientation is selected in the Page
Settings. The user should be able to set the origin to a more
convenient location, such as a reference point on a PCB.
2. Allow the user to set the positive X and Y directions from that
reference point. This would allow a user to display Y-axis
coordinates increasing from bottom to top, or decreasing as it is now.
I want to accomplish these goals in a consistent manner across all
editors (Schematic, Footprint, and Layout) without causing major
revision to the internal representations.
Could this be integrated into the work your doing to handle internal
