How to get the size of a QWidget in QTabWidget

[wysota]

Hi,I have a QTableView in a QTableWidget

addTab(new MyTableView,tr("what"));

addTab(new MyTableView,tr("what"));

To copy to clipboard, switch view to plain text mode 

You mean a table view inside a tab widget?

How can I get the viewport of the QTableWidget.

If you ask about QTableWidget then use its viewport() method. If you ask about the tab widget then it doesn't have a viewport.

Who is the parent of the QTableView.

If you mean your code snippet then the direct parent will be the stacked widget inside QTabWidget.
