Hi,
This is sample code of how it looks like:

Hi,
I'm using WTableView and everything is OK, but once I used RTL
direction I got a lot of troubles. I'm going to describe the
situation:
When Icalled setLayoutDirection with parameter Wt::RightToLeft
at project startup, I noticed thatthe columns headers was not in
the correct position, some columns cannot be viewed when
scrolling (the middle columns in my case from 7 to 15) and the
performance was not as usual. Y <http://i.share.pho.to/8600dda9_o.png>ou
can see how it looked by clicking this link <http://i.share.pho.to/8600dda9_o.png>.
I'm using:
- Same WTableView as shown in Virtual scrolling
<http://www.webtoolkit.eu/widgets/trees-tables/mvc-table-views>example.
- WBootstrapTheme
- Witty 3.3.0.1
- Qt Creator 2.8.1 Based on Qt 5.1.1 (GCC 4.6.1, 64 bit)
- Linux Mint
Is this normal behavior or I'm doing something wrong?
Regards,
Nasser
