The variable `m_Initialized` in `BASE_SCREEN` is used by
`SCH_EDIT_FRAME` to mark whether a screen had its zoom level initialized
by the "zoom to fit screen" action. When this variable is `false`, the
function `SCH_EDIT_FRAME::DisplayCurrentSheet()` performs "zoom to fit
screen", modifying the zoom level. This function is indirectly called in
the undo routines, so if `m_Initialized` is not set to `true`, a zoom
change will occur when the user undoes an operation, a behavior that is
undesired.
`m_Initialized` was not initialized to `true` for the null schematic
(the schematic that is loaded if no project is loaded), causing the
aforementioned undesired behavior.
To prevent this, I've changed the `SCH_EDIT_FRAME` constructor to set
`m_Initialized` to `true`, since it zooms to fit screen already. I've
moved `m_Initialized` from `BASE_SCREEN` to `SCH_SCREEN`, as it is used
only in Eeschema, and renamed it to `m_zoomInitialized`, a name I
believe that better describes what this variable does.
I've also introduced the function `SCH_EDIT_FRAME::initScreenZoom()` to
group the "zoom to fit screen" action with setting `m_Initialized` to
`true`, as they often should occur together.
I'd also like to say that I'm not confident whether
`SCH_EDIT_FRAME::DisplayCurrentSheet()` should perform the zoom level
initialization at this point, but I have decided to not change this
behavior for now, as the commit history suggests it's several years old.
Fixes https://gitlab.com/kicad/code/kicad/issues/7343
The groundwork has now been laid for per sheet instance data. Initially
this only supports sheet page numbers but could be expanded to include
other per sheet instance information.
ADDED: Support for user defined schematic page numbers.
* Split up the thirdparty code into the thirdparty folder (#3637)
* Create a new kimath static library containing all the math functions
This is part of cleaning the build system for #1906.
When loading a part in libedit, also transfer certain screen
settings to the incoming SCH_SCREEN, from the current
SCH_SCREEN.
Currently, the grid settings are transferred, but this could
also do other settings if needed.
Also remove some duplicate commentary and mention why the
grid is set in a SCH_SCREEN even though the BASE_SCREEN ctor
sets the same default.
Fixes: lp:1815108
* https://bugs.launchpad.net/kicad/+bug/1815108
Replace all instances of wxLogDebug with wxLogTrace in the common and
kicad folders to prevent unwanted debugging output.
Add new trace flags for locale and screen object tracing.
The usual smattering of code policy fixes.
* Add code to allow each editing window it's own undo/redo count.
* Add code to allow for infinite undo/redo when count is set to 0.
* Add edit control to all editing windows general options dialog for
user configuration of undo/redo count.
* Add code to save and restore undo/redo count for each editing window.
*) add hotkey for setting the grid origin as 'S', in board editor, module editor.
*) re-position the function interface for cursor movement from BASE_SCREEN into
class EDA_DRAW_FRAME. This is a prelude to getting rid of BASE_SCREEN or
splitting it up.
This may have been an undocumented bug from more than a year ago, which manifested itself in *.mod files containing duplicate names.
LEGACY_PLUGIN loads those now quietly, but appends "_v2", "_v3", etc. to each succeeding duplicate sharing the same name.
as a starting point
* Make double Distance() take double arguments and remove internal range checking.
* Start on EDA_DRAW_FRAME::AdjustScrollBars() and use "double" for most all calculations
in anticipation of setting INT_MAX INT_MIN limits eventually.
// This provides better project control over rounding to int from double
// than wxRound() did. This scheme provides better logging in Debug builds
// and it provides for compile time calculation of constants.

*) for footprint access into *.mod files and
*) BOARD save/load
The item_io.cpp and ioascii.cpp have been set off to the side for reference
as *.notused, for awhile.
The CMake options USE_NEW_PCBNEW_LOAD and USE_NEW_PCBNEW_SAVE are gone,
this is now the mandatory usage of the LEGACY_PLUGIN. This should reduce
code maintenance for awhile until the s-expression plugin comes into
play. But at least for legacy format, there is not two code bodies
to maintain any more.
A new LEGACY_PLUGIN footprint library caching scheme is in place which
needs some testing. It should not be any faster, but might give better
results in a networked environment if there is *.mod files on the server.
* Remove internal units from BASE_SCREEN and it's derivatives.
* Remove internal units from EDA_DRAW_FRAME and it's derivatives.
* Use build time code to replace internal units conversions.
* Fix scaling bug in page layout sample window that I created in my
last commit.
