So In QWebView I want to have MyOwnTextEdit instread of QTextEdit and same for all other UI controls.

Please tell me How can I do it?

I am using Qt embedded linux 4.6.2.

For example, you can see how this kind of things realized in more easy widgets here: link text. It's the first way. The second way is to create you textbox with SIGNALs/SLOTs and also code widgets GUI with Qt styles. Good luck!
