Drawing a line in Writer fails after update

English
, , ,
#1

Hi all!

Merry Christmas!

Following example has worked until half a year ago.
Now it fails at “cursor.add(oShape)”.

The code draws a line in writer and saves the document.

Note: I am aware that there are some other ways to invoke and control LO.
I was like if it ain’t broke don’t try to fix it.

Best regards,

Hello!

Are you sure this thing worked before? I just don’t see Add(graphic shape) among the text cursor methods

Perhaps this was previously in the DrawPage? Yes, there is definitely an Add() method

Indeed. Nice tool, I was unfamiliar with it.
Replacing:
cursor.add(oShape)
with

dp = doc.getDrawPage()
dp.add(oShape)

results in

Unspecified Application Error
Fatal exception: Signal 6

Am I using a wrong DrawPage here?

I didn’t discover why your macro isn’t running (I don’t know Python well), but here is macro that inserts the shape (number 2) to document.
I ran LibreOffice with these parameters for Python: “–accept=socket,host=localhost,port=2002,tcpNoDelay=1;urp;StarOffice.ComponentContext” --norestore

Thank you, your answer is definitely a priceless contribution to the Writer shape drawing topic! Perfect!

Here is still angular polygon (only with straight edges), there are only coordinates of points and no flags. Small improvement is only the Point(…) instead def createPoint

import uno

from com.sun.star.awt import Point

def rgb(r, g, b):
    return 256*256*r + 256*g + b

localContext = uno.getComponentContext()
resolver = localContext.ServiceManager.createInstanceWithContext( "com.sun.star.bridge.UnoUrlResolver", localContext )
smgr = resolver.resolve( "uno:socket,host=localhost,port=2002;urp;StarOffice.ServiceManager" )
remoteContext = smgr.getPropertyValue( "DefaultContext" )

desktop = smgr.createInstanceWithContext( "com.sun.star.frame.Desktop",remoteContext)
doc = desktop.loadComponentFromURL( "private:factory/swriter","_blank", 0, () )
oPage=doc.DrawPages[0]

oShape=doc.createInstance("com.sun.star.drawing.PolyPolygonShape")
oPage.add(oShape)
oShape.PolyPolygon=[ [Point(0,291), Point(0,248), Point(72,248), Point(72,49), Point(2,93), Point(2,47), Point(75,0), Point(130,0), Point(130,248), Point(196,248), Point(196,291)] ]
oShape.LineStyle=0
oShape.FillColor=rgb(255, 0, 0)

Figured it out. Needed redo the entire thing. Working code below.

How to draw a line with pyuno?
