Thanks Guru.
But in work fine on whole site.
In my case I have mixed content, so I need to put RTL in post DIV.
I ready to customize the theme.
But I don’t know what is language of current post ?

I looking for some function,
like qtranxf_use_block that can return $alt_lang for current post.

What is that function name ?

I dont found apropriated function in qTranslateX, so here is my work around:
I found here and here function for determinate “is my text string need RTL”

function is_str_rtl( $string ) {
    $rtl_chars_pattern = '/[\x{0590}-\x{05ff}\x{0600}-\x{06ff}]/u';
    return preg_match($rtl_chars_pattern, $string);
}

I renamed is_rtl to is_str_rtl because in E:\work\ihockey.info\wp-includes\locale.php is_rtl already defined and has different meaning.

Put this function to functions.php
And use it my template
`<?php if ( have_posts() ) : while ( have_posts() ) :
the_post();
$title = get_the_title();
$rtl = ”;
if(is_str_rtl($title))
$rtl = ‘ dir=”rtl” ‘;
?>
<div class=”post_body” <?php echo $rtl; ?> >`
