Hi,
huummm,
i need help for a big challenge for me, for tinymcev4 for xoops.
It is for the 
class image...
(For an example the the 
MACTEP demo)
Here i try to explain :
In tinymce, there is a new definition : 
image_class_listThis option lets you specify a predefined list of classes to add to an image.
In TinyMCE code
 /* Example of how to use link class list. */ 
    image_class_list: [ 
        {title: 'None', value: ''}, 
        {title: 'Dog', value: 'dog'}, 
        {title: 'Cat', value: 'cat'} 
    ];  
In our /class/xoopseditor/tinymce.php/tinymce4 file :
 $ret .='image_class_list: [ 
        {title: "'._XOOPS_EDITOR_TINYMCE4_Undefined.'", value: ""}, 
        {title: "img-shadow-middle", value: "img-shadow-middle"}  
    ],';  
ok, all is ok with that, all works, but but it"s hard coded !!!
So,
we get the "content_css" variable to tell tinymce where is our style.css file is !
here, in our /class/xoopseditor/tinymce.php/tinymce4 file :
 $this->setting["content_css"] = implode( ",", $this->loadCss() );  
It returns : 
http://my_web_site.com/themes/my_theme/style.cssok,so,
i want to use a function which discovers in the style.css all img class
for example : 
in style.css :
 img.img-shadow-left { 
    box-shadow: 5px 5px 20px #555555; 
    vertical-align: middle; 
    float: left; 
    margin: 10px 10px 10px 0px; 
    border-color: #ffffff; 
    border-style: solid; 
    border-width: 20px; 
    display: block; 
} 
 
img.img-shadow-right { 
    box-shadow: 5px 5px 20px #555555; 
    vertical-align: middle; 
    float: right; 
    margin: 10px 0px 10px 10px; 
    border-color: #ffffff; 
    border-style: solid; 
    border-width: 20px; 
    display: block; 
} 
 
img.img-shadow-middle { 
    box-shadow: 5px 5px 20px #555555;  
    border-color: #ffffff; 
    border-style: solid; 
    border-width: 20px; 
    display: block; 
    margin-l; 
    margin-left: auto; 
    margin-right: auto; 
    margin-top: 10px; 
    margin-bottom: 10px; 
}  
then the function returns :
img-shadow-left
img-shadow-right
img-shadow-middle
and 
create AUTOMTICALLY :
 $ret .='image_class_list: [ 
        {title: "'._XOOPS_EDITOR_TINYMCE4_Undefined.'", value: ""}, 
        {title: "img-shadow-left", value: "img-shadow-left"}  
        {title: "img-shadow-right", value: "img-shadow-right"}  
        {title: "img-shadow-middle", value: "img-shadow-middle"}  
    ],';  
Hope I'm Clear for you, hope you understand me.
Who could help me, or write the code ?
It's not just for me, it's for best TinyMCEv4 integration.
