Description tzuktz 2009-02-19 12:25:56 UTC
When using parentheses with Hebrew in a presentation they look OK during editing
but wrong during presentation.
Comment 1 wolframgarten 2009-02-19 12:29:03 UTC
Please attach a document for testing. Thanks.

Attached bugdoc.

The mirroring of the parentheses seems to be fixed in OOO310_m1.

However, there is another problem. Will attach screenshot. 
The parentheses are misplaced, probably because the text string is handled in
LTR order instead of RTL. If you set the text direction to LTR, you will get the
same placement in edit mode.

Comment 5 wolframgarten 2009-02-20 07:57:09 UTC
In ooo310m1 the doc looks ok for me in edit mode and in presentation mode. After
setting the text to LTR I can see the problem of your screenshot.  I have
attached some screenhots: is this the problem you see?

Comment 7 hennerdrewes 2009-02-23 08:02:31 UTC
I get the same "directly after opening" result. However, when I go to
presentation mode, I get the LTR result, even if the text was set to RTL in edit

Checked this on Vista Sp1. Will check the document again on XP later on, could
be Vista specific, if you failed to reproduce on XP.
Comment 8 hennerdrewes 2009-02-23 10:23:59 UTC
@wg: I can reproduce the effect also on Win XP. 

Under Tools, Options, View: Hardware acceleration is turned on. If I turn it
off, the display is correct also in presentation mode.

Comment 10 hennerdrewes 2009-09-23 09:03:56 UTC
In dx_textlayout.cxx, settings for text direction were simply ignored.

I copied the corresponding code from vcl based textlayout.cxx to
dx_textlayout.cxx and dx_textlayout_drawhelper.cxx, and this seems to fix the

The problem still persists in current version 3.4.1

I don't see any relevant changes made to the source files on trunk recently, so I assume that the patch is still applicable. 

Unfortunately I don't have a build environment set up at the moment to verify.
