Property:
* Extended property status bitset. Mirror most of PropertyType and
allow dynamic change property type.
* Cache property name and type to improve performance
* Centralize property status change signalling
* Change aboutToSetValue()/hasSetValue() to virtual
* Add new API getFullName() to obtain full quanlified name of the property
AtomicPropertyChangeInterface:
* Allow calling aboutToSetValue()/hasSetValue() when actually changed
PropertyLists:
* Refactor implementation by an abstract class PropertyListBase and a
template class PropertyListsT, to allow better code reuse.
PropertyListT is derived from AtomicPropertyChangeInterface to allow
more efficient change on individual elements.
* All list type property now accept setting python value as a dictionary
with index as key to set individual element of a list.
* Add touch list for more efficient handling of value changes. The list
contains the index of changed value. And empty touch list should be
treated as the entire list is changed. PropertyContainerPy expose this
functionality with getPropertyTouchList().
PropertyPersistentObject:
* New property to allow dynamic creation of any FreeCAD object derived
from Base::Persistence, and use it as a property.
DynamicProperty:
* Use boost multi_index_container for efficient property lookup while
keeping order.
* Modify to be allowed to use in PropertyContainer directly
PropertyContainer:
* Use boost multi_index_container for efficient property lookup while
keeping order.
* Allow adding/removing dynamic property on all property container
* Modify Save/Restore() to persist property status, and better handle
transient property which can now be dynamically enabled/disabled per
object.
* Add new API getFullName() to obtain full quanlified name of the property.
Implemented by Document, DocumentObject, and also
ViewProviderDocumentObject if future patch
DocumentObject and FeaturePython are modified to accommondate the
dynamic property changes.
Removed get/setCustomAttribute() implementation from DocumentObjectPy,
and rely on PropertyContainerPy for the implementation, because of the
additional dynamic property support in property container.
Gui::ViewProviderDocumentObject, which is derived from
PropertyContainer, is also modified accordingly
DocumentObject:
* getSubObject(): the most important API for Link to work with
hierarchies. The function is a inspired from and replaces the
getPySubObjects(). It returns a child object following a dot separated
subname reference, and can optionally return accumulated
transformation, and/or a python object of the refered
sub-object/element. The default implementation here is to look for
link type property, and search for the referenced object. This patch also
include other specialized implementation of this API, such as
(GeoFeature)GroupExtension (through extensionGetSubObject()),
PartDesign::Body, and so on. A link type object is expected to
call the linked object's getSubObject() for resolving.
* getSubObjectList(): helper function to return a list of object
referenced in the given subname.
* getSubObjects(): return a list of subname references of all children
objects. The purpose of this function is similar to
ViewProvider::claimChildren(). Container type object is expected to
implement this function. The reason it returns subname references
instead of just object is to allow the container to skip hierarchies.
For example, the Assembly3 container uses this to skip the constraint
and element group.
* getLinkedObject(), obtain the linked object, and optionally with the
accumulated transformation. It is expected to return a linked object
or the object itself if it is not a link. In case there are multiple
levels of linking involved, this function allows the caller to retrieve
the linked object recursively.
* hasChildElement(), set/isElementVisible(), controls the children
visibility for a group type object. Because the child object may be
claimed by other objects, it is essential to have independent control
of children visibilities. These APIs are designed to abstract how
group manages the child visibility. For performance reason, these
function are meant to control only the immediate child object.
* resolve(), helper function to parse subname reference and resolve the
final object, and optionally the immediate parent of the final object,
the final object reference name (for calling `set/isElementVisible()`),
and the subname reference if there is one.
* touch(), add optional argument 'noRecompute' for better backward
compatibility with the NoRecompute flag. By default, touch() causes
recompute unless noRecompute is true
* signalChanged/signalBeforeChange, two new signal for tracking changes
of a specific object.
* getViewProviderNameOverride(), return a string of the view provider
type of this object. This allows Python class to override the view
provider of an object. This feature will be used by ViewProviderLink
which is designed to work with any object that has LinkBaseExtension.
* canLinkProperties(), will be used by Gui::PropertyView to display
linked object properties together with the object's own properties.
* redirectSubname(), will be used by Gui::Tree to allow an object to
redirect selection to some other object when (pre)selected in the tree
view.
* Visibility, new property serve as the same purpose as view provider
property of the same name. It is added here so that App namespace
code can check for visibility without Gui module. This is useful,
for example, when constructing a compound shape of a container that
respects the children visibility.
* (has)hasHiddenMarker(), return or check for a special sub-element
name used as marker for overriding sub-object visibility. Will be
used by Gui::ViewProvider, it is put here for the same reason as
adding Visibility property.
* getID(), return object internal identifier. Each object is now
assigned an integer identifier that is unique within its containing
document.
Document:
* ShowHidden, new property to tell tree view whether to show hidden
object items.
* signalTouchedObject, new signal triggered when manually touch an
object when calling its touch() function
* getObjectByID(), get object by its identifier
* addObject() is modified to allow overriding view provider
* has/getLinksTo(), helper function to obtain links to a given object.
Application:
* checkLinkDepth(), helper function to check recursive depth for link
traversal. The depth is checked against the total object count of
all opened documents. The count (_objCount) is internally updated
whenever object is added or removed.
* has/getLinksTo(), same as Document::has/getLinksTo() but return links
from all opened documents.
GroupExtension/OriginGroupExtension/DatumFeature/DatumCS/Part::Feature:
implement sepcialized getSubObject/getSubObjects().
add a special XMLAttributeError class to indicate an error when accessing a missing attribute
in PropertyContainer::Restore make error handling more flexible
+ some are doxy others are just comment code.
+ some minor whitespace and grammatical tweaks.
+ app/SCL/* typos have also been submitted upstream (https://github.com/stepcode/stepcode/pull/366). So it's ok to merge them in to master.
A new document object App::TextDocument. It has a property Text which
holds the text of the document as a string. This commit also contains a
full size editor based on QPlainTextEdit. It can only be used by the
TextDocument and has a read only mode invoked for read only documents
(ReadOnly property set to true). The editor is invoked by a double
click on the TextDocument.
