Solved 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); }
