* Prevent power component warning from being shown when edit normal component
fields.
* Make text edit dialog size itself instead of using a fixed size.
* Improve the alignment and spacing in the text edit dialog.
* Refactor edit one field dialogs to use validators and transfer data to and
from window functions.
* Add code to DIALOG_SHIM to handle validation and transfer functions since
the base dialog class code is not called by EndQuasiModal().
* Add custom validator class for filtering field text control characters.
* Add new field validator to edit schematic component dialog field text
control.
* Add new field validator to edit fields in library editor dialog field
text control.
* Make a few LIB_PART member functions const.
- When the Kicad manager is iconized, all other child frames are iconized (normal wxWidgets behavior)
- For viewer frames in modal mode, there is a more annoying issue: they have the wxFLOAT_ON_PARENT frame style on unix, and wxSTAY_ON_TOP on Windows.
wxFLOAT_ON_PARENT frame style is incorrect (although on most WM it works) because the parent frame (Kicad manager Frame) is not the caller. It is usually a main editor frame.
It does not work on Windows (wx STAY_ON_TOP is used).
* Now each editor frame has a null parent.
Therefore iconizing the Kicad manager frame does not iconize other frames.
* Viewer frames have null parent in normal mode and the caller parent in modal mode (therefore wxFLOAT_ON_PARENT frame style is always and correctly used)
* References to opened/closed main frames are no more managed by the (complicated) kicad code. Instead of, a non critical and more easy to understand code just uses FindWindowByName to know if a main window exists or not.
These changes do not fix all issues about Kicad frames brought to the foreground or the background, but it fixes a few issues, and AFAIK do not add other issues.
* Derive SCH_SHEET_LIST from std::vector rather than using internal array
management. Change all internal code to use iterators or array operator
in loops.
* Allow creation of empty SCH_SHEET_LIST for external population for plotting
and printing.
* Clean up print an plot code to take advantage of new SCH_SHEET_LIST behavior.
* Make BuildSheetList() public so list can be populated after creation.
* Update all instances of SCH_SHEET_LIST with the appropriate SCH_SHEET
object on initialization.
* Create const and non-const version of SCH_SHEET_PATH::GetSheet().
* Derive SCH_SHEET_PATH from std::vector< SCH_SHEET* > and remove unnecessary
assignment operator and list management functions.
* Remove function BuildSheetPathInfoFromSheetPathValue() since it was
effectively an assignment operation.
* Replace all calls to BuildSheetPathInfoFromSheetPathValue() with assignment
operator.
* Replace list management functions with vector management functions.
* Fix a error message that wasn't translatable.
* Remove wxDC and EDA_DRAW_FRAME parameters from SCH_SCREEN::SchematicCleanUp()
function call.
* Update all code that calls SCH_SCREEN::SchematicCleanUp() with wxDC and/or EDA_DRAW_FRAME
parameters.
* Fix a display refresh bug when incrementally inserting bus entries created in my last commit.
IsDanglingStateChanged() appears to be broke for bus entries.
* Fix parent of elements in wxSizers.
* Update old dialog with recent version of wxFormBuilder.
* Add wxALIGN_CENTER_VERTICAL flag to some dialogs.
* Update wxFormBuilder timestamp in generated sources.
This class wraps the comparison function in a way that is compatible with
std::map and std::set. This, too is generally useful, so it should be moved
to the generic header.
At the same time, the criterium for less-than is changed from "equal to -1"
to "smaller than 0", because technically the comparison function may return
other values.
* Add sheet number that is set by schematic file load order. This duplicates
the previous SCH_SHEET_PATH behavior.
* Uncouple SCH_REFERENCE and SCH_REFERENCE_LIST from SCH_SHEET_PATH.
* Add - operator to SCH_SHEET for comparison purposes. This duplicates the
behavior of SCH_SHEET_PATH::Cmp().
* Uncouple SCH_COMPONENT::GetRef() from SCH_SHEET_PATH and use SCH_SHEET
instead.
* Uncouple SCH_COMPONENT::GetUnitSelection() from SCH_SHEET_PATH and use
SCH_SHEET instead.
* Fix all calls to GetRef() and GetUnitSelection() to pass a pointer to the
appropriate SCH_SHEET object instead of an SCH_SHEET_PATH object.
* Use wxGrid to edit default fields in option dialog which allows user to
directly instead a separate edit panel.
* Implement TransferData{To,From}Window methods.
Including the inline of the Output directory and its text field/browse button.
Moving the plot format to the left of the plot options as the plot options depend on the plot format.
Pcbnew: Plot files: for copper layers, create suffix from user copper layer names instead of default copper layer names, like in last stable Kicad version (bzr 4022), to build the plot files filenames.
Better test of illegal chars in plot filename, both in plot dialog and functions aclled by Python scripts.
Fix a Plotcontroller issue to make SetUseGerberExtensions() work as expected from Python scripts ( from Henner Zeller'patch with a fix to be sure it works properly from a Python script)
Note also using Protel Gerber Extensions is now a bad practice, because the official Gerber extension is .gbr since X2 Gerber version. But some users still use them)
* Make the about dialog help string consistent across all menus.
* Improve print preview window and print initialization error messages.
* The usual smattering of coding policy fixes.
* Rename Eda_FileSelector to EDA_FILE_SELECTOR.
* Add optional pointer to wxString to save the most recently used path to EDA_FILE_SELECTOR.
* Rename Eda_DirectorySelector to EDA_PATH_SELECTOR.
* Replace wxGetCwd() with wxStandardPaths::GetDocumentsDir(). This fixes the windows issue
where wxGetCwd() returns the path where the executable files are located.
* Add code to handle most recently used path to EDA_BASE_FRAME.
* Fix string formatting error in kicad/files-io.cpp.
* Remove setting and restoring current working directory when launching GerbView. Setting the CWD
has no effect on the launched executable which starts with it's own CWD.
* Allow project path to be passed to GerbView when launched from KiCad.
* Note: this is a work in progress. Do not expect every path and/or file selection dialog to properly
update the most recently used path. The correct solution to this problem requires a much more
well though out solution which will not happen until after the next stable release.
* Move color conflict checking code into TranferDataFromWindow so that it can be used in both the
OK and Apply button message handlers.
* Change Erc to ERC in text labels.
* Check for color conflicts and give the user the option to dismiss the changes before applying them.
* Add color conflict checking when apply button is pressed.
* Use default dialog size to allow sizers to set the initial size of the dialog.
* 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.
- Slightly change the info text in the dialog. Add a definition of exactly what it means to "rescue" a component.
- Reload the project libraries when a project is opened, even if kicad is already running and the same project is open (to be sure the lib cache is up to date).
- Set the Modified flag on cancel, because a change has indeed been made (choosing not to rescue is equivalent to updating the components)
* Components with multiple "converts" were rendered with all of them overlapping instead
of just one.
* Schematics missing a -cache.lib resulted in unnecessary renaming suggestions.
* The dialog title "Conflicts Checking" is inaccurate now (as we're checking for more than
just conflicts) and also somewhat awkward, unidiomatic GUI English; I renamed it to
"Project Rescue Helper".
* Eliminate modal annotation warning dialog when generating a netlist fails
due to components that are not annotated.
* Add warning message to annotate dialog.
* Change 'Silent mode' -> 'Always ask for confirmation'. Default on
(Same behavior as before, though arguably, it is very annoying and
should probably be default off)
* 'Automatically close dialog' -> 'Keep this dialog open'. Also changed
the default to _not_ keep the dialog open (what is keeping it open even
useful for ?)
* Remove global s_NetObjectslist.
* Separate out non-owning version of NETLIST_OBJECTS_LIST into NETLIST_OBJECTS.
* Fix double free pertaining to ~NETLIST_READER().
* Remove all file-io from CvPCB.
* Remove exe launcher cvpcb, retain only cvpcb.kiface, since cvpcb.kiface has no file i/o.
* Add void CVPCB_MAINFRAME::KiwayMailIn( KIWAY_EXPRESS& mail ) and teach it to use old
netlist loading code with a STRING_LINE_READER LINE_READER.
* Fix BEGIN_EVENT_TABLE( CVPCB_MAINFRAME, KIWAY_PLAYER )
* Add code to test if any of the components in the schematic cache have been changed
in the component libraries.
* Prompt user to accept or reject components when changes are found.
* If the user chooses to use the components in the cache, create a new library with the old
components and add it to the beginning of the component library list so the schematic will
not be changed.
* Create dialogs to handle user feedback and status.
Now these parameters are stored in user config, not project config ( they are not really related to a given project, they are just a setup during an edition),
and the schematic editor and the component editor have now separate parameters, because they are separate editors with different constraints.
component editor: repeat pin enhancement (from and idea of Edward Johns)
Previously, only the lib named "power" was used (and therefore power parts defined in other libs not shown).
Now, all power parts can be loaded from any library.
Also, when loading power parts from the chose component dialog or the lib viewer, libs and parts are filtered: only power parts and libs containing power parts are listed.
Hotkeys: move a few global strings in the files where ther are actually used (and make them local.) and code cleaning.
Fix a few other minor issues.
* The SCH_COLLECTOR m_foundItems was being obsoleted after a pin name search.
If a library edit changed the found pin name, the cache still held the now
missing library pin and would segfault on next search due to the cache being
out of date.
This is due to the fact static strings flagged translated ( _("string") notation) are not translated when they are static only if they are not inside a dll.
When they are static inside a dll, the dictionary is already loaded, and the constructor translate them.
Therefore they can be translated twice in dialogs are calling wxGetTranslation to show them, if the application is run from kicad.
But if the application is run as stand alone, the translation is made only once (as expected).
Fix minor 3D viewer issues (includling change number of segments and its optimization to draw pad holes.)
Fix Bug #1439132 (track and via list on toolbar not always refresh after loading a board).
Remove useless tool in Modedit.
Move items rework: enhancements: for some items (sheets, components, bus entries) the mouse cursor is no more wrapped to the anchor. For large symbols, this is better: they are more easy to place.
There is also a change when starting a move item command: the full screen is redraw, and therefore there is no artifact due to the XOR draw mode.
Some other minor coverity fixes (uninitialized members).
* move not shared files (sch_item_struct.*, sch_base_frame.h) to eeschema;
* move wxEeschemaStruct.h to eeschema and rename it schframe.h to be consistent with the other corresponding file name schframe.cpp;
* remove few not needed #include
Rename eeschema/dialogs/dialog_sch_find.fbp to dialog_schematic_find_base.fbp, to be consistent with other dialogs.
Pcbnew run from the project manager: add menu Save Copy As..., which is the same command as Save As ... in stand alone mode, but with the constraints of a project (no cwd change, no board filename change, and keep project settings)
* Fix -Woverloaded-virtual warning in DIALOG_LIB_NEW_COMPONENT class
definition.
* Make EDA_ITEM::Matches( const wxString& wxFindReplaceData& ) protected
since it's a helper function that should only be called by derived objects.
* Make generate button the default in Eeschema netlist dialog.
* Fix spacing issues in export IDF dialog.
* Make OK button the default in export IDF dialog.
* Remove unnecessary end dialog code from export IDF dialog.
* Improve resizing of export IDF dialog.
BOM dialog: remove a not very useful button, and merge its function with an other (not perfect, need more work)
Add message box to show info added in BOM python scripts (See scripts/bom-in-python/README-bom.txt about this info)
* Fix assertions in Eeschema when editing net labels, electronic rules check,
and plotting.
* Fix assertion when opening PCB calculator.
* Fix assertions in Pcbnew when changing footprints in footprint properties
dialog and adding or editing text.
steps to better support devices with precise scrolling deltas (trackpads).
Scrolling is done in the handler rather than creating and firing cmd events.
This is intended to support two-finger scrolling on the Magic Trackpad.
- Added a preference, 'Use mousewheel to pan', to allow panning by default
on mousewheel events. This reverses the existing behavior where unmodified
mousewheel zooms and Shift/Cmd modified pans.
The old behavior was:
- Unmodified scrollwheel performed zoom in/out
- Shift modified scrollwheel performed pan up/down
- Cmd modified scrollwheel performed pan left/right
- Shift+Cmd modified scrollwheel performed zoom in/out
with no cursor warp
With the new preference checked, this changes to:
- Unmodified scrollwheel performs pan up/down
- Shift modified scrollwheel performs pan left/right
- Cmd modified scrollwheel performs zoom in/out
- Shift+Cmd modified scrollwheel performs zoom in/out
with no cursor warp
With the preference unchecked, this is now:
- Unmodified scrollwheel performed zoom in/out
- Shift modified scrollwheel performed pan left/right
- Cmd modified scrollwheel performed pan up/down
- Shift+Cmd modified scrollwheel performed zoom in/out
with no cursor warp
It should be noted that for the last case, the behavior has changed.
This is not arbitrary. This now matches expected behavior for an OS X
application. This also matches what wxWidgets expects on this platform
as wxWidgets changes the axis of mousewheel events to horizontal when
the event is shift-modified.
The preference is added everwhere that mouse preferences previously
existed, i.e., eeschema, pcbnew and gerbview. The 3D Viewer does
not yet honor this preference, but behaves as if it was checked.
The pl_editor does not currently have any preferences to honor.
As with the magnify event support, this covers canvases for all
current tools, EDA_DRAW_PANEL, EDA_3D_CANVAS and EDA_DRAW_PANEL_GAL.
This does NOT modify the behavior of mousewheel zooming, though it
probably should. This remains unsuitable for use with a trackpad,
use pinch-to-zoom instead.
* Include new field template editor
- Removes 10 template limitation
- Adds ability to set default value
- Adds ability to set default visibility
* Documentation to follow
* Tested in Linux (Ubuntu 14.04) + Windows, Windows has issue with displaying highlight for selected template, fix to follow
Fix dialog title to be "Electrical Rules Checker" to match everywhere else.
Fix all usages of "Erc" to "ERC" consistently.
Move action buttons to bottom of dialog, make Del Markers actually say Delete Markers.
Add tooltips to ERC options matrix buttons to indicate what their current state is, for newb friendliness.
Cleanup ERC options code that for some reason decided to delete the button and recreate it instead of just updating it's bitmap directly.
Rename "Test Erc" to "Run" because you are running ERC and not testing it.
Fix improper usage of SetLabel on a wxTextCtrl instead of SetValue so the ERC totals now work!
Schematic component properties dialog: add 2 helper buttons to manage the chip name (name of the corresponding part in lib)
- a browse button to chose an other chip name
- a test button, to know if the part exists. If not existing, list the parts found when searching using a case insensitive comparison.
However to be compatible with old versions of Eeschema, when a search in library fails, a case insensitive search is made.
Therefore, this version should be compatible with sch files created by previous Eeschema versions compiled with KICAD_KEEPCASE = OFF
Ensure some values initialized by the schematic editor and used by libedit are also initialized in libedit even if the schematic editor was not started.
Remove useless commands (save/load project config) in libedit, because now they have no sense.
* Refresh canvas when user cancels edits so that the discarded sheet is
cleared from the schematic.
* Add file name validation to the sheet properties dialog to prevent
illegal file name characters from being entered into the text control.
* Rename FOOTPRINT_NAME_VALIDATOR to FILE_NAME_CHAR_VALIDATOR for clarity.
*) When kicad.exe closes a project, close any open KIFACEs so that they cannot
get disassociated from their true PROJECT.
*) Allow loading eeschema library editor from kicad.exe
*) Allow loading pcbnew library editor from kicad.exe
*) Rename LIB_COMPONENT to LIB_PART.
*) Add class PART_LIBS, and PART_LIB.
*) Make PART_LIBS non-global, i.e. PROJECT specific.
*) Implement "data on demand" for PART_LIBS
*) Implement "data on demand" for schematic SEARCH_STACK.
*) Use RSTRINGs to retain eeschema editor's notion of last library and part being edited.
*) Get rid of library search on every SCH_COMPONENT::Draw() call, instead use
a weak pointer.
*) Remove all chdir() calls so projects don't need to be CWD.
*) Romove APPEND support from OpenProjectFiles().
*) Make OpenProjectFiles() robust, even for creating new projects.
*) Load EESCHEMA colors in the KIWAY::OnKiwayStart() rather in window open,
and save them in the .eeschema config file, not in the project file.
*) Fix bug with wxDir() while accessing protected dirs in kicad.exe
*) Consolidate template copying into PROJECT class, not in kicad.exe source.
*) Generally untangle eeschema, making its libraries not global but rather
held in the PROJECT.
Remove a minor warning message in Debug mode for 2 dialogs.
Pcbnew: update Gerber X2 file format (File Attribute) to very last X2 specification
Eeschema: Fix a minor bug in block selection (sometimes the last selected component was select instead of items in selected area)
and better drag behavior when draging an item by the drag hotkey.
Also fix incorrect backannotation when footprint names contain spaces (put spaces in names is always a bad idea)
* Fix minor Bug #1349058 Choose component dialog: Search field loses focus after entering a character and internationalize the dialog.
* Fix a subtle bug which prevent eeschema to read the project config file when launched from kicad manager, and when kicad.pro is not found.
They are now member of EDA_DRAW_FRAME.
This change could fix Bug #1330781 (Background color change in Eeschema affects background color in Pcbnew)
Show page limits has meaning only for the schematic editor, the board editor and the page layout editor.
Draw background color selection exists only in eeschema and page layout editor.
In pcbnew, only a black background is allowed.
A side effect is now the user should set the background color in schematic editor, and the library editor (2 different options).
The default is still the white color.
Change class PROJECT to use a generalized wxString in place of the
RETAINED_PATH items, so that new session and project specific strings
of any purpose can be saved there, for the life of a session.
*) Eeschema can now show the footprint editor.
*) Eeschema can now invoke the footprint picker from the library part field editor.
*) KIWAY_PLAYER::ShowModal() takes aResultantFocusWindow that tells what window
to give the focus to. Required since frames are often near the top of the
hierarchy and they are invoked by a peer, not a parent.
*) KIWAY_PLAYER::IsModal() is now a retained state, controlled by SetModal()
*) Fully re-work the KIWAY_PLAYER::ShowModal() to use a nested event loop.
*) Add support to DIALOG_SHIM for a "quasi-modal" dialog presentation and mode.
See top of dialog_shim.cpp about that for benefits and need.
*) You can now pick footprint from the schematic component field dialog, although
if you do this before you open the BOARD, you will only get the global footprint
libraries, not also the project specific ones. Opening the BOARD first avoids this
problem.
This is the first example of cross KIFACE invocation, it is also the first
instance of using a TOP_FRAME other than FRAME_PCB as the first thing. It works,
but it's missing support for opening the project specific table because
historically the FRAME_PCB did that. This is now starting to expose all the near
term needs for KIWAY_PLAYER <-> PROJECT interaction, independence and out of
sequence usage.
A fix for this will be coming in a few days.
However it mostly starts to show why the KIWAY is terribly useful and important.
was used locally. Then comment it out in favor of a newer strategy for
filling in nicknames in cvpcb.
Add MODULE* FootprintLoadWithOptionalNickname( const FPID& aFootprintId )
throw( IO_ERROR, PARSE_ERROR );
from code found elsewhere.
! 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.
* getpart.cpp: fix a potential bug on a translatable string with has requirements in spelling.
* fix bug #1066179
* kicad: fix erroneous labels in sub menus.
* Pressing 'Enter' while the focus is in the tree did not work due to the
double-click wxWidgets workaround. Make it work.
* More clearly document what is happening and how it can be tested.
* Manually change fbp file minor version number so dialog could be edited
with latest release version of wxFormBuilder.
* Give component view panel more weight for improved component view size.
* Add padding around dialog button sizer.
* Improve component chooser redraw to fit in wxWidgets redraw strategies.
* Use LIB_COMPONENT::Draw and LIB_COMPONENT::GetBoundingBox for drawing the
component
* Make resize redrawing work properly.
* Allow to select units in components that have more than one right in the
component chooser dialog.
* Keep chosen unit in history.
* Show preview of current component unit as thumbnail image next to the
description box.
* Fixes lp:1280567
* make some more fields 'const' that can.
* Instead of previous/next _visible_ element, Go through
previous and next element. Otherwise the cursor stops moving
if the item is only partially visible.
* Replace all occurrences of the word "part" with "unit" when referring to
multiple unit components for improved consistency.
* Replace "shared by" with "common to" when referring to objects (lines, arcs,
pins, etc.) that are common to all units.
* Improve wording in library component properties dialog.
* Fix replace bug to handle case sensitivity properly.
* Fix replace bug where the item index was getting updated incorrectly.
* Fix replace infinite loop bug on replace all.
* Make find/replace view update code a separate function.
* Rearrange find/replace trace string to add tracing to EDA_ITEM::Replace().
* Add IsComplexHierarchy method to SCH_SHEET_LIST for future find/replace
improvements.
Fix an annoying issue about not named nets:
now, these nets are named from the component references and pin names which are connected.
therefore, unless the net or the footprint references are modified, the net name is not modified between 2 netlist calculations.
* Use a regular expression to enforce more stringent bus label testing.
* Add validator to edit label dialog to prevent space character from being
used in labels.
dialogs which allow editing of component properties. The button
is active when the table row cursor is on the DATASHEET field only.
When active, and your datasheet is a URI, then your default
browser will be launced to show that datasheet if it can find it.
This incentivizes use of http:// links for datasheets.
*) 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.
* Force search when wrap past end of list option changes state.
* Fix SCH_FIELD::Matches() for bug in user defined fields which have an ID
of -1.
* Minor improvements to the find data names to improve source code readability.
