How do I code for different widget passed ?

How do I code (C++) for different widget passed  to a function ? 


I am trying to learn how to pass variable wiglets  to a function and 
code the function for variable widgets. 
. 
 Here is my function 

int  Form::UpdateForm(QWidget *widget, QString text)  ) 

And this is how I use it: 


UpdateForm((QTextEdit*)ui->textEdit, "TEST TRACE ");

In this case I pass  QTextEdit but I cannot use methods for 
QTextEdit. I can only use generic QWidget methods. 

widget.append(text)  does not compile - no such method for "widget" .

I ask Mrs Google but she only does when the function is declared with specific type of widget. I need a variable type of widget to process.

Any (C++ code) help would be appreciated.

You need to make a cast of the variable:

QTexEdit* edit=qobject_cast<QTextEdit*>(widget);
if(edit)
{
edit->append(text);
}
