My goal is to have a script that will insert text and an image at the end of a Writer doc. The attached code works fine on an empty doc, but when I run it a second time on the same document (after it contains text and an image), I get the exception

"  File "test.py", line 33, in ?
    oViewCursor.gotoEnd(False)
uno.com.sun.star.uno.RuntimeException: no text selection"


 
import sys
import Danny.OOo.OOoLib as OOoLib
import unohelper
import os.path
import glob
from com.sun.star.beans import PropertyValue
from array import array


L =  [ PropertyValue() for i in range(4)]


L[0].Name="FileName"
#L[0].Value="file:///home/ollie/Desktop/Screenshot.png"
L[0].Value="file://" + sys.argv[1]
print L[0].Value
L[1].Name="FilterName"
L[1].Value="<All formats>"
L[2].Name = "AsLink"
L[2].Value = False
L[3].Name="Style"
L[3].Value="Graphics"

desktop = OOoLib.getDesktop()
doc=desktop.getCurrentComponent()

oText = doc.getText()
xEnd = oText.getEnd()
xEnd.setString("This is some text.\n")


oViewCursor = doc.CurrentController.ViewCursor
oViewCursor.gotoEnd(False)


dispatcher = OOoLib.getServiceManager().createInstance('com.sun.star.frame.DispatchHelper') 
dispatcher.executeDispatch(doc.getCurrentController(), ".uno:InsertGraphic", "", 0, tuple(L))


#dispatcher.executeDispatch(doc.getCurrentController().getFrame(),'.uno:InsertGraphic','',0,tuple(L))

Does replacing this line:
oViewCursor = doc.CurrentController.ViewCursor
oViewCursor.gotoEnd(False)

Open in new window

With this:
oViewCursor = doc.CurrentController.ViewCursor
oViewCursor.gotoStart(True)
oViewCursor.gotoEnd(False)

Open in new window

Work? I think it needs to be forced or something

Gives me the same error on the gotoStart(True) call:

Traceback (most recent call last):
  File "test.py", line 33, in ?
    oViewCursor.gotoStart(True)
uno.com.sun.star.uno.RuntimeException: no text selection

I've figured out that the error occurs the 2nd time because after the first run, the script leaves the image as being selected in the document and the gotoEnd and gotoStart functions must be working on the current selection and not the entire document.

I'm now researching on how to fix this...

I found this method:
doc.CurrentController.select(<object>)

But it requires that another object is specified to set the selection to, where here I'd like to unselect everything. There doesn't appear to be a way to do that.

Wasn't there a getEmpty() function?

You'll have to help me out with some more specifics....

I didn't see a getEmpty() function in the api documentation:

The trick of recording a macro to see what code gets created by Writer isn't helpful here since it appears that the macro recorder doesn't record selection events.

Got this working... I added the following line to the end of the script to deselect the image. Then subsequent executions of the script ran fine.

dispatcher.executeDispatch(doc.getCurrentController(), ".uno:Escape", "", 0, tuple())
