[solved] parentwidget problem

[broadpeak]

I have an QDockWidget and I have an QTableView in my dockwidget.
In title of QDockWidget there is a QLineEdit. I'd like to reach this lineedit from my tableview:

@
QObject::connect(
((CameraDockWidget*)parentWidget())->getLineEdit(),
SIGNAL(textChanged(QString)),
filter,
SLOT(setFilterFixedString(QString))
);
@

But I have no parent :(
How can I reach the parent (or rather my lineedit)?

Why can't you introduce them to each other in the class where you add both?

Sorry, my fault was :)
I put into the child wrong class type...
