[Solved] How to check ParaAdjust value with pyUNO?

[_LX_]

How could I write conditional statements to check the paragraph adjustment while scanning a document?

Let me explain:

Code: Select all

from com.sun.star.style.ParagraphAdjust import RIGHT
...
cursor.ParaAdjust = RIGHT
print(cursor.ParaAdjust == RIGHT)
---> False

checking the types:

Code: Select all

type(cursor.ParaAdjust)
---> <class 'int'>
type(RIGHT)
---> <class 'uno.Enum'>

Checking the uno.py file I get that the uno.Enum class has two properties, typeName and value:

Code: Select all

type(RIGHT.value)
---> <class 'string'>
print(RIGHT.value)
---> 'RIGHT'

If I set the ParaAdjust property with the 5 values from com.sun.star.style.ParagraphAdjust, and then print the actual value of ParaAdjust I get:

Code: Select all

LEFT = 0
RIGHT = 1
BLOCK = 2
CENTER = 3
STRETCH = 0

(note that STRETCH is considered as LEFT, a bug or something not implemented?)

Where are these values defined?
How could I get these values using the pyUNO API?

Hi, welcome to the forum.

The enum like ParagraphAdjust is defined in relative IDL file and converted into API reference.
Its data can be accessed through type description manager. In C, enum member has only interger value but the type description provides access to members by their names.
In general, to check the relative page of the enum value is enough: http://www.openoffice.org/api/docs/comm ... djust.html

If you want to get name to value map of enum values, try the following code written in Basic:

Code: Select all

Sub GetEnumValues
  tdm = GetDefaultContext().getByName("/singletons/com.sun.star.reflection.theTypeDescriptionManager")
  v = tdm.getByHierarchicalName("com.sun.star.style.ParagraphAdjust")
  names = v.getEnumNames()
  values = v.getEnumValues()
  s = ""
  for i = 0 to ubound(names) step 1
    s = s & names(i) & ": " & cstr(values(i) & chr(10)
  next
  msgbox s
End Sub

Hi hanya,
thank you for the welcome and thanks for your answer.

Let me share the python code of a function that returns a dictionary with the mapping of the enum values:

Code: Select all

def get_paragraph_adjust_values():
    tdm = uno.getComponentContext().getByName("/singletons/com.sun.star.reflection.theTypeDescriptionManager")
    v = tdm.getByHierarchicalName("com.sun.star.style.ParagraphAdjust")
    return {name: value for name, value in zip(v.getEnumNames(), v.getEnumValues())}

(note: with python 2.6 the dictionary can be created using the dict() function instead of the comprehension form)

Just for curiosity, I've noted that using the previous function 'STRETCH' is mapped to '4' (as expected), but if I set the value of ParaAdjust with

Code: Select all

from com.sun.star.style.ParagraphAdjust import STRETCH
cursor.ParaAdjust = STRETCH

or with

Code: Select all

cursor.ParaAdjust = 4

ParaAdjust is initialized to '0', why?
