Refactored code to support local and external material sources
This is the first PR in a series to support external modules. External
modules allow materials to be stored in external data sources such as
databases or web services. No new functionality is introduced in this
PR, rather it is a refactoring of code that will allow for changes to
be introduced in future PRs. Minor performance improvements have also
been made in the model and material managers.
The Python API has been enhanced for many data types to allow for
modification within Python.
Every basic data type is stored in Base module, color is standing out as
one that does not. Moving it to Base opens possibilities to integrate it
better with the rest of FreeCAD.
Add properties for setting a minimum size with reasonable defaults.
Notify the user when the tree is expanded or contracted to allow
for container resizing.
Improves the use of the ShapeAppearance property for the Part workbench.
removes DiffuseColor property
adds Python compatibility using custom attributes
transitions DiffuseColor to ShapeAppearance on open
Improved UI elements for setting object appearance, and appearance per face
Lays the foundation for future texture support
Updates the material preferences including selecting a default material
Preferences adds some options for what gets displayed in the Materials editor.
The option to use the legacy editor is removed in favour of the new
editor.
A new preference page has been added that allows the user to select a
default material. This will then be assigned to any newly created object. In
support of this, a new widget PrefsMaterialTreeWidget has been added as an
extension of the MaterialTreeWidget to automatically save and restore the
selected material.
Improves the MaterialTreeWidget beyond minimum viable product.
- Filters can now be filter lists to allow a variety of filtering
options.
- User preferences allow the inclusion/exclusion of favorites and
recents.
- Widget state such as expansion, tree expansions, etc are saved and
restored.
- show current appearancee material when editing.
- implements a python interface
#fixes 13421: always opens full tree
* fix warning -Wunused-variable
* fix warning -Wreorder-ctor
* fix warning -Wunused-but-set-variable
* fix uic warning for DlgDisplayProperties.ui
* rename the target MateriaTestLib ALL (note the typo and the already existing MaterialTestLib ALL) to MaterialTest ALL
drop the hard dependency to the Part module: The document is checked for a property ShapeMaterial of type Materials::PropertyMaterial.
An alternative could be to cast to GeoFeature and use the methods getMaterialAppearance() and setMaterialAppearance()
Uses new material system for appearance
Each feature object now has a property called ShapeMaterial that
describes its physical properties. If it has a shape, it has a
material.
The ShapeColor attribute is replaced by a ShapeAppearance attribute.
This is a material list that describes all appearance properties, not
just diffuse color. As a list in can be used for all elements of a
shape, such as edges and faces.
A new widget is provided to allow the user to select materials in a
consistent fashion. It can also launch the material editor with its
more advanced capabilities.
