Hmm now that I think about it, I don't think this is really possible at compile time. You have to consider issues like multiple bases (Through either a linear chain of inheritance, or multiple inheritance cases). If there were only a way to simplify this. Specifying the base class in two places is obviously error-prone, and I am hoping there are other solutions to cleaning this up. On Tue, Jun 9, 2009 at 1:36 PM, Robert Dailey wrote:

Hey everyone, I'm using wxWidgets, and as you all may know they have a silly macro used to define an event table...

BEGIN_EVENT_TABLE( MainWindow, wxFrame ) EVT_CLOSE( MainWindow::OnClose ) END_EVENT_TABLE()

I spend a few hours finding out that wxFrame is the incorrect parameter for parameter #2. This is not the base class that MainWindow derives from. There was no compiler error or warning, nor any errors during runtime. Only weird behavior because events were getting skipped.

Because of this error-proneness, I'm looking for a way to have boost help me out with this. I'm looking for a metafunction in Boost that can be used to obtain (at compile time) the base type of MainWindow. For example:

BEGIN_EVENT_TABLE( MainWindow, boost::get_base_of<MainWindow>::type ) EVT_CLOSE( MainWindow::OnClose ) END_EVENT_TABLE()

Something like that above. I know that type traits has is_base_of, and I'm hoping there is a get version of that too. I've browsed through the reference but I've found nothing helpful.
