How to delete an already existing layout on a widget?

Asked 2011-09-23T12:06:32.733

You must first delete the existing layout manager (returned by layout()) before you can call setLayout() with the new layout.

Which function is used for deleting the previous layout?

qt qt4

You just use

delete layout;

like you would with any other pointer you created using new.
