Description John Gray 2011-06-15 04:40:17 UTC
In both 3.3.2 and 3.4.0, I specified the default tab settings to be at 0.50 inch positions (having started Writer and clicked on Tools -> Options -> LibreOfficeWriter -> General tab, and in Settings set up the Measurement Units to be inches and the Tab Stops at 0.50"), but in the first instance I tested  the ruler shows that they are placed slightly short of the correct location, such that when you get to the end of the ruler the tab is at about 6.45" not at exactly 6.50".

Specifying the spacing at 0.51" gets tabs placed even further away from the required 0.50" locations!

The tab locations on the ruler seem to depend somewhat on the Zoom level.  Occasionally they are "spot on", like they always are in Word, but the locations vary in their imprecision between Portrait and Landscape and especially with the Zoom level.

Localisation is GB, document size is A4, orientation is (usually) portrait, operating system is fully-patched XP Pro SP3.

This bug was filed before the changes to Bugzilla on 2011-10-16. Thus it
started right out as NEW without ever being explicitly confirmed. The bug is
changed to state NEEDINFO for this reason. To move this bug from NEEDINFO back
to NEW please check if the bug still persists with the 3.5.0 beta1 or beta2 prereleases.
Details on how to test the 3.5.0 beta1 can be found at:

Comment 3 sasha.libreoffice 2012-02-29 07:28:46 UTC
reproduced in 3.3.4 and 3.5.0 on Fedora 64 bit
change version to 3.3.4 as most early reproducible

I don't think I'm accurate enough to do this test :)
But after some testing, I didn't see anything wrong with tab settings (several change to some values). Position on ruler is correct (subject to my eyes ;))

Tested on LO (Win7 32bit) with English standard installation & centimeter as measurement unit.

Please REOPENED this bug if you don't agree & attach that screenshot (if possible)

reproduced in on Fedora (RFR) 64 bit
In screenshot on top we seen horizontal ruler. There are numbers and tabstops beneath of them. They should be exactly beneath. But actually they are slightly shifted to left. For example one tabstop should be exactly beneath "10". And currently it is not.
This behaviour depends on zoom. For different zoom values error of placing tabstops is also different.
If we type characters in document alternated with dabs then we see that they also not placed beneath tabstops. On right hand side they are slightly misplaced. Tapstops placed wrongly.

You're right Sasha, it's slightly diminished. Zooming also change that.

Sorry for not paying attention thoroughly :)

If you have time, please do the following:

    Test to see if the bug is still present on a currently supported version of LibreOffice (4.4.1 or later)

    If the bug is present, please leave a comment that includes the version of LibreOffice and your operating system, and any changes you see in the bug behavior

2. Test your bug
3. Leave a comment with your results.
4a. If the bug was present with 3.3 - set version to "inherited from OOo";

Not reproducible for me with LibreOffice built at home under Ubuntu 14.10 x86-64.

Closing as WorksForMe. Please, feel free to reopen if you still encounter this problem with current stable versions or the master.

Best regards. JBF
