* Add Draft_LinkArray and Draft_PathLinkArray that uses link for both
data and visualization, which supports linking external objects
* Add link group support for draft snap
* Fix ArchWindows expression ambiguity
* Relaxed valid base shape requirement, as long as it can return a
shape using part.getShape()
* Improve ViewProviderPath performance by sharing the same selection
observer
* Relocate libarea binary installation
* Support link and group objects
* Support view sync by implementing view provider API getMDIView()
* Use handleChangedPropertyType() for object migration instead of
reimplementing Restore() because of a lots of changes in
PropertyContainer::Restore().
* Various other small fixes.
* Added Part::Feature::getTopoShape/getShape() function that can obtain
shape from any object with proper implementation of getSubObject(). It
can even construct compound from group object with proper implementation
of getSubObjects().
* Modified ViewProviderExt to work on any object, because it now obtain
the shape using Part::Feature::getShape()
* Modified various Part features to obtain base/tool shapes using
Part::getShape(), which allows them to be any type of object,
including Link and groups.
* Modified various Part command to relax type requirement on selected
objects.
* Add support of link and group to dimension, and add dimension refresh
command
* Support link and group in simple command command, and add a few more
copy command variations.
* Add special handling of 'Shape' attribute in PropertyContainerPy and
use Part::Feature::getShape() to return shape for any object without
Shape property. This allows many python feature work with any object
without modification.
* GeometrySurface/CurvePy, add convenience attribute 'Rotation'
* TopoShapePy:
* Extended support of sub shape attribute, e.g. Compound1, Solid2,
SubShape3 ('SubShape' is used to access child shape of a compound)
* makeWires(), new API to sort and return wires given a list of edges.
* transformed/translated/rotated/scaled(), return a new shape with
some transformation.
* findPlane(), find the plane of a planar shape
* isCoplanar(), check if two shape are coplanar
* Better module import error handling
* Allow co-installation of Python2 and Python3 version of FreeCAD
* Add FreeCAD.Logger class for convenient logging in Python. See class
document for more details.
* Add always zoom invariant and always on top rendering to
ViewProviderDatumCS
* Add a new utility class AxisOrigin for more efficient axis rendering.
Also exposed to python.
* Change ViewProviderPlacement to use AxisOrigin for rendering.
A single instance of AxisOrigin is shared by all
ViewProviderPlacement. Selection context is used to distinguish among
different instances.
Support sub-object in ActiveObjectList. This means that it can now
distinguish the same object being activated under different parent,
which may be in a different document through external linking.
* Add new API and signal handler in document observer
* Pre initialize python handler function to improve performance. In
case Python code use dynamic patching, i.e. add class method at
runtime (which is rare and should be discouraged), the python feature
can be re-initialized by simply assign proeprty Proxy again.
* Add property tracking in DocumentObjectT
* WidgetFactory adds support for accepting python QIcon, which is used
by ViewProviderPythonFeature
Implement box element selection that support linked and grouped objects.
Also modified original box selection command to support the same with
the same code.
* Major refactor of tree view to support external linking.
* Item update and selection change are now mostly handled by timer for
performance improvement.
* Major change to drag and drop for better support of switching between
copy, move and replace action, and auto adjustment of placement and
relative link.
* Add second column for user changable object description.
* Unified tree view options and action into command group
Std_TreeViewActions.
* Modified object search function to find external objects using
Expression syntax.
* Display property from linked object, colored green,
* Change DlgPropertyLink to support external linking and sub-object
selection
* Improve large selection performance by using a timer
* Improve TAB key behavior in property editor
* Add context menu to show hidden properties, change property status,
set expression on any and property, and add/remove dynamic properties
* Optimize expression completer model construction, as the original
implementation gets prohibitively slow for moderate number of objects.
This patch includes the actual implementation of Link, which is
implemented as an extension named LinkBaseExtension in App namespace,
and a full view provider ViewProviderLink in Gui. The reason of not
using ViewProviderExtension is because it need full control when
display, not just extending existing functionalities.
Please see [here](https://git.io/fjPue) for more details of the
implementation.
This patch also includes a set of link manipulation commands, and a
task panel for overriding geometry element colors.
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.
The link support means that an object can now appear in more than one
places, and even inside a document different from its own. This patch
adds support for in-place editing, meaning that the object can be edited
at correct place regardless where it is.
See [here](https://git.io/fjPIk) for more info about the relavent APIs.
This patch includes two example of modifications to support in-place
editing. One is the ViewProviderDragger, which simply adds the dragger
node to editing root node by calling
View3DInventorViewer::setupEditingRoot(dragger). The other much more
complex one is ViewProviderSketch which calls setupEditingRoot(0) to
transfer all its children node into editing root. ViewProviderSketch
also includes various modifications to command invocation, because we
can no longer assume the active document is the owner of the editing
object.
This patch also includes necessary modification of the 'Show' module to
support in-place editing.
* Fix AutoSaver inconsistent BinaryBrep setting
* Use temperary name when auto saving, so that it won't overwrite the
original file, which may cause corruption when crashing in the middel
of auto saving, especially if auto saving in a separate thread.
* Support auto recovery document containing external links
* Do not mark success after auto recover, in case the program crash
again before the user remember to save the just recovered file. Only
mark when user saves the document.
See bug description:
https://bitbucket.org/Coin3D/coin/pull-requests/119/fix-sochildlist-auditing/diff
Because of path based rendering (SoFCPathAnnotation) in mouse over
highlight, this bug causes crash more frequently here comparing to
upstream.
All C++ calling of SoGroup::removeAllChildren() is replaced by
Gui::coinRemoveAllChildren(), and python code is fixed by monkey
patching SoGroup.removeAllChildren() in FreeCADGuiInit.py.
The patch implements context-aware selection and rendering in 3D view.
Please check [here](https://git.io/fjiY5) for more details, including
the following 'Render Caching' section.
The patch also includes modification of View3DInventorViewer to support
always-on-top selection rendering using the secondary selection context
and the new coin node SoFCPathAnnotation.
Another small change in SoQtQuarterAdaptor for more responsive frame
rate display. The original implementation reports skewed frame rate
in the presence of long idle period.
Mostly about API changes to SelectionSingleton. Also include related
changes to SelectionObject, SelectionChange, and SelectionView.
Please check out the summary of changes [here](https://git.io/fjimC)
* invoke(), distinguish between command triggering source. Also add
support of auto transaction using App::AutoTransaction. Now all
command will support undo/redo by default.
* setupCheckable(), a helper function to Improve support of
PythonGroupCommand
* getObjectCmd(), helper function to output Python command to refer to
an object without ambiguity. Because with introduction of external
linking, an object can no longer be safely referred through the
current active document.
* Support auto MacroManager command logger. For commands that does not
log any output to MacroManager, a log entry of 'Gui.runCommand()' will
be auto generated.
* Support linked object in copyVisual()
* Modified do/runCommand() to print calling file and line number.
* Add various helper macros for run command involving a document or
object.
Context aware selection makes it possible to select the same Coin3D node
in different hierarchies (i.e. context) without ambiguity.
New/modified APIs in ViewProvider (the first two are the most crucial
APIs for context aware selection to work):
* getElementPicked(), supercedes getElement(). Given a Coin3D pick
point, this function returns a dot separated subname reference as a
path leads to the selected object.
* getDetailPath(), supercedes getDetail(). Given a subname reference,
this function returns an SoFullPath leads to the Coin3D node of the
selected object or sub-element (with SoDetail).
* (has)HiddenMarker(), check/return a special text marker for context
aware override of object visibility.
* partialRender(), render only part of the object based on given
subname references. It can render, e.g. some faces of a solid, or
some children of a container. It uses the 'secondary' extension of
SoSelectionElementAction to select which elements to render or hide.
The actually rendering functionality will be added in the following
patch.
* update()/onChanged(), modified to sync Visibility property from
DocumentObject.
* useNewSelectionModel(), modified to return the default true view
parameter. This is for test in the early stage of Link development,
probably not needed anymore.
* getBoundingBox(), a convenience function to obtain the bounding box
of a sub-object/element regardless of object's visibility. It uses
getDetailPath() and SoGetBoundingBoxAction to obtain bounding box
through Coin3D. It will be used in later sub-element box selection
functionality.
New/modified APIs in ViewProviderDocumentObject:
* getElementPicked()/getDetailPath() provides actual implementation to
support container like (sub)object selection without ambiguity. It
relies on DocumentObject::getSubObject() to walk the path.
* reattach(), called when undo deleteion
* forceUpdate()/isUpdateForced(), force update even if object is
invisible. These are used by Link to force update the visual of a
linked object regardless of its visibility.
* getLinkedViewProvider(), return the linked view provider with
hierarchy.
ViewProviderDocumentObjectPy:
* Object attribute is made writtable. Assigning it is equaivalant of
calling ViewProviderDocumentObject::attach() in Python.
Some of these new APIs are not strictly needed for Link to work, but
good to have.
Summary of the API changes:
* getModeSwitch/getTransformNode() exposes view provider mode switch
and transformation coin3D node, required by ViewProviderLink to
override placement and visibility.
* canAddToSceneGraph() inform 3D viewer whether to add the root node to
scenegraph. Some object only exists as a child of some coordinate
system. Not adding them can simplify scenegraph and visibility
management.
* showInTree() inform tree view whether to show the corresponding tree
item.
* getDefaultMode() to expose the current active mode regardless of the
view provider's visibility
* (can)DropObjectEx() superseds (can)DropObject() with additional
support of subname reference, which makes it easy to support linking
to sub-objects. One of the use case is cross coordinate system
linking.
* getDropPrefix() is used to tell tree view where the object is dropped
into. A non empty return means the object is actually dropped into a
sub-object. For example, Assembly3 container puts all dropped object
into its child container PartGroup.
* canDragAndDropObject() is used to inform tree view whether the object
dropped need to be dragged out of its original parent, which usually
does not make sure for Link type object.
* beforeDelete() will be called by Gui::Document when either the
object itself is being deleted or when the document is being
destoried.
* is/setLinkVisibility() allows to show/hide a link to this object.
This may be used during editing, to prevent showing editing geometry
in multiple places.
* update() is made a virtual function, it will be overridden by
ViewProviderDocumentObject in future patch.
* startEditing() now becomes virtual, and return a ViewProvider that
actually handles the editing. This is for future Link type object to
forward editing request
* covert(), convenience function to convert between Coin3D and FC matrix
ViewProviderExtension also gains many relavant extension point of the
new API. There is also the new extensionModeSwitchChange() for notifying
mode switch changes
ViewProviderPy exposes several method/attribute for the new API as well.
These are the bare minimum set of APIs for future new topogical naming
feature (see [here](https://git.io/fj6hy) for a overview of the new
APIs).
These APIs are added early to avoid too much code change for the new
features introduced in the current patch set.
The future patch will introduce Part::getTopoShape() to construct a
compound shape from a group. It will rely on the children visibility to
determine whether to include the child shape or not. This patch adds
children visibility tracking capability to group, and makes sure that
the group object will be marked for recomputation in case of any change
in group member, and their visibility status.
* Remove Prop_Output from 'Group' property.
* Added hidden property _GroupTouched to help propagate children change.
* Track children visibility change using signal
* GeoFeatureGroupExtension uses new PropertyLinkBase interface for
scope checking.
