createEnumeration problem

[karpo518]

Hi. I have a problem. For example, text document contains 5 paragraphs. I edit paragraphs in loop. I add 'new line' symbols chr(13) in some paragraphs. I got more than 5 paragraphs in result, but loop will have 5 iterations only and does not get all paragraphs. How i can solve this problem?

It would help if you could show the code you are using that does not perform as you expect it to.

robleyd, thanks for answer. My code[python] below:

Code: Select all

    model = XSCRIPTCONTEXT.getDocument()

    tCursor = model.getText().createTextCursor()

    tCursor.gotoStart(False)
    tCursor.gotoEnd(True)
    
    eIterator = tCursor.createEnumeration()

    while eIterator.hasMoreElements():

        pCursor = eIterator.nextElement()
        if pCursor.supportsService("com.sun.star.text.Paragraph") and pCursor.String != '':
           pCursor.String = pCursor.String + " prepared" + chr(13) + "test paragraph"

    return None

This code edits text:

Paragraph 1
Paragraph 2
Paragraph 3
Paragraph 4
Paragraph 5

to:

Paragraph 1 prepared
test paragraph
Paragraph 2 prepared
test paragraph
Paragraph 3 prepared
test paragraph
Paragraph 4
Paragraph 5



Paragraphs 4 and 5 a not prepared.

Hello,

Try something like this:

Code: Select all

	model = XSCRIPTCONTEXT.getDocument()
	text = model.getText()
	eIterator = text.createEnumeration()
	while eIterator.hasMoreElements():
	    pCursor = eIterator.nextElement()
	    if pCursor.supportsService("com.sun.star.text.Paragraph") and pCursor.String != '':
	       pCursor.String = pCursor.String + " prepared" + chr(13) + "test paragraph"

or more pythonic (LibO 5.x only):

Code: Select all

   model = XSCRIPTCONTEXT.getDocument()
   text = model.getText()
   for elem in text:
       if elem.supportsService("com.sun.star.text.Paragraph") and elem.String:
          elem.String += " prepared\rtest paragraph"

Hi, hubert lambert. Method getText() returns all objects of document. I process selected textRanges only.

[hubert lambert]

I process selected textRanges only.

That was'nt obvious.Could you explain how you get then selection?

[karpo518]

I got code from andrew pitonyak's book. I use paragraphs loop in function FormatWorker()

Code: Select all

...
model = XSCRIPTCONTEXT.getDocument()
oCurs = CreateSelectedTextIterator(model)

if oCurs is None :
    msgBox("No selected text")
    return None

for i in range(0, len(oCurs)):
    FormatWorker(oCurs[i][0], oCurs[i][1], model, ".*")
...


def CreateSelectedTextIterator(oDoc):
    if not IsAnythingSelected(oDoc):
        return None
    else:
        oSels = oDoc.getCurrentSelection()
        lSelCount = oSels.getCount()
        oCurs = []

        for lWhichSelection in range(0, lSelCount): 
            oCurs.append([])
            oSel = oSels.getByIndex(lWhichSelection)
            oLCurs = GetLeftMostCursor(oSel)
            oRCurs = GetRightMostCursor(oSel)
            oCurs[lWhichSelection].append(oLCurs)
            oCurs[lWhichSelection].append(oRCurs)
    return oCurs

def IsAnythingSelected(oDoc):
    if(oDoc is None):
        return False
    oSels = oDoc.getCurrentSelection()
    if(oSels is None) or (oSels.getCount() == 0):
        return False

    if (oSels.getCount() > 1):
        return True
    else:
        oSel = oSels.getByIndex(0)
        #msgBox(oSel.ImplementationName)
        if oSel.supportsService("com.sun.star.text.XTextRange") :
            msgBox("Поддержка текстовых интервалов")


        oCursor = oSel.getText().createTextCursorByRange(oSel)
        if not oCursor.isCollapsed(): 
            return True
    return False


def GetLeftMostCursor(oSel):
    if oSel.getText().compareRegionStarts(oSel.getEnd(), oSel) >= 0 :
        oRange = oSel.getEnd()
    else:
        oRange = oSel.getStart()
    oCursor = oSel.getText().createTextCursorByRange(oRange)
    oCursor.goRight(0, False)
    return oCursor

def GetRightMostCursor(oSel):
    if oSel.getText().compareRegionStarts(oSel.getEnd(), oSel) >= 0 :
        oRange = oSel.getStart()
    else:
        oRange = oSel.getEnd()
    oCursor = oSel.getText().createTextCursorByRange(oRange)
    oCursor.goLeft(0, False)
    return oCursor

Keeping a separate reference to paragraphs seems to work (could be a kind of bug):

Code: Select all

	model = XSCRIPTCONTEXT.getDocument()
	selection = model.CurrentSelection
	elements = []
	for element in selection[0]:
		elements.append(element)
	for element in elements:
		if element.supportsService("com.sun.star.text.Paragraph") and element.String:
			element.String += " prepared\rtest paragraph"

hubert lambert, thanck you. I will test this solution later.

[musikai]

Does it work? If not then it might because you make an enumeration but while going through it you edit the document. Going in reverse order (backwards) might help. Also test if the selection range adapts if you are adding more paragraphs. The start should be the same but I'm not sure about the end.

[karpo518]

Thanks for answers. The proposed method solves my problem.
musikai, it is works, but it is compromiss solution. I wanted to get ability to adding paragraph without problem in loop or dynamic initialization of the iterator
