			davidedmundsonUnsubmitted Done do we not also need a disconnect on m_browser? davidedmundson: do we not also need a disconnect on m_browser?
			brunsAuthorUnsubmitted Done Browser is just an interface class, but the subclasses also derive from QObject and should auto-disconnect, AFAIK. bruns: Browser is just an interface class, but the subclasses also derive from QObject and should auto…

			broulikUnsubmitted Done Please provide `this` as context. broulik: Please provide `this` as context.
			brunsAuthorUnsubmitted Done you mean `this->mbrowser->teardown()`? bruns: you mean `this->mbrowser->teardown()`?
			broulikUnsubmitted Done No, four-argument connect: connect(this, &..., this, .... Though you just connect from `this` anyway, so I guess this isn't needed broulik: No, four-argument connect: ``` connect(this, &..., this, .... ``` Though you just connect from…
			brunsAuthorUnsubmitted Done Hm, just found that auto-disconnect (see @davidedmundson s comment) only works if you provide a context. The context has to be `m_browser` here. bruns: Hm, just found that auto-disconnect (see @davidedmundson s comment) only works if you provide a…
			broulikUnsubmitted Done Ah, yeah, right, and then you could connect direcftly: connect(this, &Plasma::AbstractRunner:teardown, m_browser, &Browser::teardown); broulik: Ah, yeah, right, and then you could connect direcftly: ``` connect(this, &Plasma…
			brunsAuthorUnsubmitted Done yes, after readding the `dynamic_cast<QObject>`, m_browser is a non-QObject interface class. bruns:* yes, after readding the `dynamic_cast<QObject*>`, m_browser is a non-QObject interface class.
			brunsAuthorUnsubmitted Not Done The only syntax which works is connect(this, &Plasma::AbstractRunner:teardown, dynamic_cast<QObject>(m_browser), [this] () { m_browser->teardown(); }); The context object has to be a QObject (or derived). &Browser::teardown is not a pointer to a QObject member function, thus we need a functor. The other approach would be to make Browser a QObject derived class. bruns: The only syntax which works is ``` connect(this, &Plasma::AbstractRunner:teardown…
