Re: [platform-ui-dev] Workbench BIDI support flips everything?

[Bianca Xue Jiang <bjiang@xxxxxxxxxx>]

The pie chart was drawn using BIRT (http://www.eclipse.org/birt)
SWT charting engine.  If it is related to the limitation you mentioned,
does that mean swt graphics won't work on BIDI systems?  Do you know
of any documentation on this?

What I can't understand though is on
a Hebrew system, the chart shows up correctly with RTL orientation.  But
the workbench itself is still left-to-right. Is that expected?

Thanks,

Bianca Jiang

Most likely you are seeing a limitation in the usage of GDIplus, which
is used by SWT's advanced graphics.

When we conduct our globalization testing for BIDI support, we usually
set the system locale to a BIDI language speaking country (e.g. Hebrew
in Israel) in "Regional and Language Options" if not on a native
platform. Starting eclipse this way doesn't  seem to make the workbench
right-to-left.  However, in TPTP, we have a Test Log Viewer editor
that contains a graphical pie chart. The pie chart is displayed correctly
in this case (note the legend used to be on the right hand side of the
pie in a English locale, as well as inside the legend, icons used to be
at the left side of the text pass, fail...):

However, if I use "-dir rtl" or "-nl he" with eclipse.exe,
the workbench started with all UI parts flipped including the pie chart
which is no longer readable:

Which one is the correct case with BIDI language like Hebrew?  Does
eclipse.exe has to be started with -dir or -nl options on a BIDI system?
 If so, should all the graphics be flipped at all?

Your help on this will be very appreciated.
