Examples are usually a good way to get to know a new codebase, do not teach developers who are new to Qt about the 3-arg connect() to begin with. Drive-by changes: - `this` can't be implicitly captured with [=] in a lambda, instead capture by reference - Update docs related to the sqlbrowser example; the overloaded signal it mentions has been removed in Qt6 - In the sqlbrowser example, rename addConnection() (no-arg) overload to openNewConnectionDialog, suggested in code review Change-Id: I30c9f35bda4ac2f460d767ab7f84422ae3ed09f7 Reviewed-by: Volker Hilsheimer <volker.hilsheimer@qt.io>
