|
|
|
|
It draws a frame with information on the software used to create
|
|
the test document, and fills it with every object that can be created.
|
|
|
|
Parameters
|
|
----------
|
|
file_name: str, optional
|
|
It defaults to `'draft_test_objects'`.
|
|
It is the name of the document that is created.
|
|
|
|
The `file_name` will be appended to `file_path`
|
|
to determine the actual path to save. The extension `.FCStd`
|
|
will be added automatically.
|
|
|
|
file_path: str, optional
|
|
It defaults to the value of `os.environ['HOME']`
|
|
which in Linux is usually `'/home/user'`.
|
|
|
|
If it is the empty string `''` it will use the value
|
|
returned by `App.getUserAppDataDir()`,
|
|
for example, `'/home/user/.FreeCAD/'`.
|
|
|
|
save: bool, optional
|
|
It defaults to `False`. If it is `True` the new document
|
|
will be saved to disk after creating all objects.
|
|
|
|
font_file: str, optional
|
|
It defaults to `'/usr/share/fonts/truetype/dejavu/DejaVuSans.ttf'`.
|
|
It is the full path of a font in the system to be used
|
|
to create a `Draft ShapeString`.
|
|
If the font is not found, this object is not created.
|
|
|
|
Returns
|
|
-------
|
|
App::Document
|
|
A reference to the test document that was created.
|
|
|
|
To Do
|
|
-----
|
|
Find a reliable way of getting a default font to be able to create
|
|
the `Draft ShapeString`.
