Number or string representation of a Writer TextRange

[JeJe]

Posting this as wanted it a while ago but didn't think it was available from Basic.

Every paragraph has an id no so a text paragraph's textrange position will be that ID plus the character offset from the start of the paragraph.

Below example gets the paragraph ID and character positions of the selection (viewcursor), clears that selection, then restores it using that information. Select some text in a document, run main.

Tested on OO only, may not work with something more complicated than just text paragraphs.

Code: Select all   Expand viewCollapse view




Sub Main
   dim paraID1 as string,charNO1 as string,paraID2 as string,charNO2 as string

   'get paraID and charno representation of viewcursor start and end of textranges
   tc =thiscomponent.text.createtextcursorbyrange(thiscomponent.currentcontroller.viewcursor.getstart)
   getTextRangeParaIDAndCharNo(tc,paraID1,charNO1)
   tc =thiscomponent.text.createtextcursorbyrange(thiscomponent.currentcontroller.viewcursor.getend)
   getTextRangeParaIDAndCharNo(tc,paraID2,charNO2)

   thiscomponent.currentcontroller.select(thiscomponent.text.getstart) 'clear selection by moving viewcursor to start


   msgbox paraID1 & "," &  charno1 & chr(10) &  paraID2 & "," &  charno2
   'restore selection from paraIDs and charno
   tc3 = setTextRangeFromParaIDAndCharNo(thiscomponent,paraID1,charno1)
   tc4 = setTextRangeFromParaIDAndCharNo(thiscomponent,paraID2,charno2)
   tc3.gotorange(tc4,true)
   thiscomponent.currentcontroller.select(tc3,false)

end sub

sub getTextRangeParaIDAndCharNo(tc,byref paraID as string,byref charNo as string)
   tc.gotostartofparagraph(true)
   cno= len(tc.string)
   en = tc.createenumeration
   do until en.hasmoreelements = false
      p =en.nextelement
      paraID =endval( p.localname)
      charNo = cno
      exit do
   loop
End sub

function setTextRangeFromParaIDAndCharNo(componentv,paraID as string,charNo as string)
   lenno = len(paraID)
   en = componentv.text.createenumeration
   do until en.hasmoreelements = false
      p =en.nextelement
      if right (p.localname,lenno) = paraID then
         tc =componentV.text.createtextcursorbyrange(p)
         tc.gotoStartOfParagraph(false)
         tc.goright(val(charNO),false)
         setTextRangeFromParaIDAndCharNo=tc
         exit do
      end if
   loop
End function

Function EndVal(st As String) As Long


   Dim i As Long, a As Integer, s As String, res As String
   res = ""
   s = ""
   For i = Len(st) To 1 Step -1
      s = Mid(st, i, 1)
      a = Asc(s)
      If a >= 48 And a <= 57 Then
         res = s & res
      Else
         Exit For
      End If
   Next
   EndVal = Val(res)
End Function




Edit: didn't include the endval function to get the number at the end of a string - added.

Didn't know about paragraph Id's.
Usage?
Why not just use cursor.gotorange()?

[JeJe]

The point is its a way of saving the range position... to a text file/property/for later whatever. Otherwise you can only know where a textrange is in relation to another text range and you can't do that.

Para Ids are potentially very useful to me. If you identify a paragraph by number... say the 15th para in the document... then the position may change if the document is edited. Using the para id the correct para can still be found. I could have a note or data for that para (in a property or an external file) without there needing to be a placeholder in the document marking the note.

With some help from Lupp, a bit more involved version that handles a selection that is in a textframe, texttable, header or footer too.
