This function has two conflicting definitions in the "kicad" executable and
the other wrapper programs. As the kifaces can be loaded from either, this
silently assumes compatible data layout for the PGM_KICAD and PGM_BASE
types when passed by reference, which is valid only when the compiler is
aware of the cast.
If the return type is encoded in the symbol name (such as when using the
MSVC compiler), this also causes an error during linking, as the symbol
names no longer match.
The functions involved in the problem were PGM_BASE::GetEditorName and
EDA_BASE_FRAME::OnSelectPreferredEditor:
1) OnSelectPreferredEditor showed a dialog to allow the user selecting the
editor, but before that called GetEditorName to get the name of the current
editor (to show as a default in the choose file dialog).
2) The problem was when there was no editor, GetEditorName showed its own
dialog.
3) So the user was seeing first the dialog from (2) and then the dialog from
(1).
4) As GetEditorName is used in many other places the solution I did was to add
to it an optional parameter that tells it what to do if no editor is set. To
avoid modifying other code that relies on the current behaviour, this parameter
has a default value that causes to show the dialog. But now when
OnSelectPreferredEditor calls it, it passes the parameter that causes it to
return an empty string if no editor was set.
5) Also, I found a second bug while doing it which allowed in the first dialog
to select an unexistent file (the dialog was missing the wxFD_FILE_MUST_EXIST
flag).
6) Lastly, to avoid having duplicated code (the one that showed the same dialog
and that configured the wildcard was in two methods) I created a single
function that now both functions call: PGM_BASE::AskUserForPreferredEditor.
This way we also will have consistency in the behaviour of both dialogs and
there is a single place where it needs to be modified.
* Create new dialog to edit environment variables.
* Add helper class ENV_VAR_ITEM to manage environment variable values and
if they were defined externally.
* A path configuration dialog access to KiCad, CvPcb, Pcbnew, and Footprint Editor
window menus.
* Add validator for environment variables.
! The initial testing of this commit should be done using a Debug build so that
all the wxASSERT()s are enabled. Also, be sure and keep enabled the
USE_KIWAY_DLLs option. The tree won't likely build without it. Turning it
off is senseless anyways. If you want stable code, go back to a prior version,
the one tagged with "stable".
* Relocate all functionality out of the wxApp derivative into more finely
targeted purposes:
a) DLL/DSO specific
b) PROJECT specific
c) EXE or process specific
d) configuration file specific data
e) configuration file manipulations functions.
All of this functionality was blended into an extremely large wxApp derivative
and that was incompatible with the desire to support multiple concurrently
loaded DLL/DSO's ("KIFACE")s and multiple concurrently open projects.
An amazing amount of organization come from simply sorting each bit of
functionality into the proper box.
* Switch to wxConfigBase from wxConfig everywhere except instantiation.
* Add classes KIWAY, KIFACE, KIFACE_I, SEARCH_STACK, PGM_BASE, PGM_KICAD,
PGM_SINGLE_TOP,
* Remove "Return" prefix on many function names.
* Remove obvious comments from CMakeLists.txt files, and from else() and endif()s.
* Fix building boost for use in a DSO on linux.
* Remove some of the assumptions in the CMakeLists.txt files that windows had
to be the host platform when building windows binaries.
* Reduce the number of wxStrings being constructed at program load time via
static construction.
* Pass wxConfigBase* to all SaveSettings() and LoadSettings() functions so that
these functions are useful even when the wxConfigBase comes from another
source, as is the case in the KICAD_MANAGER_FRAME.
* Move the setting of the KIPRJMOD environment variable into class PROJECT,
so that it can be moved into a project variable soon, and out of FP_LIB_TABLE.
* Add the KIWAY_PLAYER which is associated with a particular PROJECT, and all
its child wxFrames and wxDialogs now have a Kiway() member function which
returns a KIWAY& that that window tree branch is in support of. This is like
wxWindows DNA in that child windows get this member with proper value at time
of construction.
* Anticipate some of the needs for milestones B) and C) and make code
adjustments now in an effort to reduce work in those milestones.
* No testing has been done for python scripting, since milestone C) has that
being largely reworked and re-thought-out.
