[Solved] Changing Header with Python (?)

[SilvaCarlosG]

Hi everyone,
I working with python with 2 pieces of RTF validated content.

I can put the content on body, but I don't know how change the Header programmaticaly by python.


Somebody can help me with this?

Thanks in advance.

Welcome to the forum ... but you have come to the wrong one.

You are probably better searching and posting in OpenOffice Basic, Python, BeanShell, JavaScript

[FJCC]

Here is some Python code recorded with MRI to access the header of the Default page style and change the text manually. At the end of the code I created a text cursor which has an insertDocumentFromURL() method in case you want to use that route.

Code: Select all

 oText = oInitialTarget.getText()
obj1 = oText.createTextCursor()
oStyleFamilies = oInitialTarget.getStyleFamilies()
        
obj2 = oStyleFamilies.getByName("PageStyles")
obj3 = obj2.getByName("Standard")
oHeaderText = obj3.HeaderText
        
oHeaderText.setString("New text for header")
obj4 = oHeaderText.createTextCursor()

oInitialTarget is the document itself, as you would get from loadComponentFromURL().

Thanks a lot, it works fine!!!!
now, My question is: How I can set a RTF content ?

[Villeroy]

Thanks a lot, it works fine!!!!

You must not use RTF with OpenOffice. ODF is the new RTF.

[SilvaCarlosG]

Hi Villeroy, in fact on body I'm using a RTF content, if I plus a valid RTF header and save the content, is a valid RTF file.

The problem that I have is I can't put the RTF content in the header. Thank's a FJCC I could put a string content in header. (Thank's a lot FJCC!)

I'm using the next code for insert the RTF content:

Code: Select all

...
input_cuerpo_Stream = StringIO.StringIO(input_cuerpo)
...
inProps1 = (
    PropertyValue( "FilterName" , 0, "Rich Text Format" , 0 ),
    PropertyValue( "InputStream", 0, InputStream(input_cuerpo_Stream), 0)
    )

cursor.insertDocumentFromURL("private:stream", inProps1)
...

Regards,
Gabriel

Plus information:

scenary 1:
when I insert the first document (ODT or OTT file) , this document has a header , and after I put the RTF content on body , and it works.

scenary 2:
when I insert the first document (ODT or OTT file), this document has a header , and after I insert the second document (ODT or OTT file) and after I put the RTF content on body , and it works. Document 1 and 2, both has tag "header" "$MYPERSONALHEADER_HEADERFILE$ and "$MYPERSONALHEADER_BODYFILE$

In scenary 1 an 2, I still haven't found the way for replace the header using a tag called "$MYPERSONALHEADER$" with the RTF content.

I mean, how can I do it programmaticaly?

[Villeroy]

This is an ODF suite which supports RTF very poorly. Write your own program to open the file and insert the tags you need.

[FJCC]

I don't understand how you mean to use the tags you mention, which is just my own ignorance. If you want to insert text from an RTF file into the header of an odt document that uses the Default page style, you can do it like this in OO Basic

Code: Select all

oText = ThisComponent.getText()
obj1 = oText.createTextCursor()
oStyleFamilies = ThisComponent.getStyleFamilies()
       
obj2 = oStyleFamilies.getByName("PageStyles")
obj3 = obj2.getByName("Standard")
oHeaderText = obj3.HeaderText
       
filePath = "c:\users\fjcc\desktop\Header text from RTF.rtf"
fileURL = convertToURL(filePath)
obj4 = oHeaderText.createTextCursor()
obj4.insertDocumentFromURL(fileURL, Array())

The Array() is an empty array. In my test, OpenOffice did not need to receive the FilterName property value in order to open the RTF file. ThisComponent is just Basic's special variable that refers to the document that called the macro. You will need to replace it with your document variable.

Thanks FJCC! it works fine, I changed a few lines of code for us purposes, and it works !!!
