Now all escaping required for the C++ code generation is done when the
.cpp/.h files are generated. Previously, only newlines were escaped
automatically. This was a) inconsistent and b) leaked c++ details into
the xml data.
In addition, the escaping is now done in one central place, harmonizing
the three previous implementations.
Pre-existing c++ escape sequences in the XML files have been replaced by
their literal equivalent so that the resulting python doc sting remains
unchanged.
Application:
* signalNewDocument, check the extra argument, isMainDoc, the decide
whether to create view of the new document. This is so that external
linked document can be opened in background without crowding the tab
list.
* slotDeleteDocument, calls Document::beforeDelete()
* slotActiveDocument, creates view if none, because external document
is now opened without view.
* onLastWindowClosed(), switch to next active document, and creates view
if none.
* send(Has)MsgToFocusView(), new API to send message to the active view
in focus. This is to solve the ambiguity of things like pressing
delete key, copy, paste handling when the active new is not in focus.
For example, when spread sheet view is active, delete/copy/paste
handling should be different when the focus on the spread sheet view
or focus on tree view.
* tryClose(), delegate to MainWindow for close confirmation
* reopen(), new API to reload a partial document in full
Document/DocumentP:
* _CoinMap, new internal map for quick access view provider from its
root node.
* slotNewObject, modified to support view provider override from
App::FeaturePython, through new API
DocumentObject::getViewProviderNameOverride().
* slotDeletedObject/slotTransactionRemove, improve handling of geo group
children rebuild
* slotSkipRecompute, add special handling of document with skip
recompute. Some command cannot work when skip recompute is active.
For example, sketcher command will check if recompute is successful
on many commands, and will undo if not. New 'PartialCompute' flag is
added to allow recompute only the editing object and all its
dependencies if 'SkipRecompute' is active.
* slotTouchedObject, new signal handling of manually touched object.
* setModified(), do nothing if already modified. This is a critical
performance improvement, because marking tab window as modified turns
out to be a relatively expensive operation, and will cause massive
slow down if calling it on every property change.
* getViewProviderByPathFromHead/getViewProvidersByPath(), new APIs to
obtain view provider(s) from coin SoPath.
* save/saveAll/saveCopy, modified to support external document saving.
* Save/RestoreDocFile(), save and restore tree item recursive expansion
status.
* slotFinishRestoreObject(), handle new signal
signalFinishRestoreObject(), unifies postprocessing in restore and
import operation.
* createView/setActiveView(), add support of delayed view creations
* canClose(), delegate to MainWindows to ask for confirmation
* undo/redo(), support grouped transaction undo/redo. Transactions may
be grouped by the same transaction ID if they are triggered by a
single operation but involves objects from multiple documents.
* toggleInSceneGraph(), new API to add or remove root node from or to
scenegraph without deleting the view object.
MainWindow:
* Update command status using a single shot timer instead of periodical
one.
* Improve message display is status bar. Give error and warning message
higher priority (using QStatusBar::showMessage()) than normal status
message (using actionLabel), reversed from original implementation.
* confirmSave(), new API to check for modification, and ask user to save
the document before closing. The confirmation dialog allows user to
apply the answer to all document for convenience.
* saveAll(), new API to save all document with correct ordering in case
of external linking.
* createMimeDataFromSelection/insertFromMimeData(), support copy paste
object with external linking. A new dialog DlgObjectSelection is used
to let user select exactly which object to export.
CommandDoc/CommandWindow:
* Related changes to object delete, document import, export, and save.
