Re: True RAD still missing in KDevelop 3.4

Ok, and I did know that. Perhaps I posted in haste. However, the usual model is to connect to the QAbstractButton::clicked signal, and not to reimplement the event handlers. I'd argue that reimplementing an event handler is quite a lot more involved than responding to a signal.

Adding to my previous post (again having posted to quickly :), there is also the issue of which event handler to reimplement.

Let's take the simple mouse click. For correct handling, the mouseReleaseEvent is probably correct, and if you want to go there it could probably be automated in the IDE to reimplement this function. Were it not automated, it would be quite easy to make the mistake of reimplementing for instance mousePressEvent, at which point the applications behaviour would deviate from other applications.

Also, as far as I know, Qt events differ from Delphi events in several aspects. It's been a while since I wrote any delphi code, but as I recall events there are more like static slot connections. That is, a certain callback is defined (usually in the form holding e.g. the button), and the button from which the event originated is passed as a parameter. I don't have any profound insights (not that I usually have any :) on what this difference means, just pointing it out.

QMetaObject::connectSlotsByName could probably be used in an IDE to achieve something similar to Delphi.
