CKEditor config doesn't change text to right-to-left - ckeditor

Question

I have edited config.js to
CKEDITOR.editorConfig = function( config )
{
// Define changes to default configuration here. For example:
config.language = 'ar';
config.contentsLangDirection = 'rtl';
contentsLanguage:'ar';
config.dialog_buttonsOrder = 'rtl';
};
But I still get the editor to be left-to-right in my Question2Answer platform. What should I do else to make my editor right-to-left?

Answer 1

Following HTML and Script worked for me, instead of using the global configuration file for application i used inline configuration as below -
HTML
<textarea id="editor" name="editor1"><p>Initial value.</p></textarea>
Script
<script type="text/javascript">
CKEDITOR.on('dialogDefinition', function (ev) {
// Take the dialog name and its definition from the event data.
var dialogName = ev.data.name;
var dialogDefinition = ev.data.definition;
// Check if the definition is from the dialog we're
// interested in (the 'image' dialog).
if (dialogName == 'image') {
// Get a reference to the 'Image Info' tab.
var infoTab = dialogDefinition.getContents('info');
// Remove unnecessary widgets/elements from the 'Image Info' tab.
infoTab.remove('browse');
infoTab.remove('txtHSpace');
infoTab.remove('txtVSpace');
infoTab.remove('txtBorder');
infoTab.remove('txtAlt');
infoTab.remove('txtWidth');
infoTab.remove('txtHeight');
infoTab.remove('htmlPreview');
infoTab.remove('cmbAlign');
infoTab.remove('ratioLock');
}
});
CKEDITOR.config.contentsLangDirection = 'rtl';
CKEDITOR.replace('editor');
</script>
