Layout problems with FXSwitcher

I finished chapter 5.4 and I run into a strange problem which I cannot fathom out on my own.
My code looks more or less like the sample code for 5.4 and I run into a problem with it(I also replaced my code with the online version, but it is the same).
My first album, created in PictureBook#initialize() is in the AlbumListView. I import some photos and they are arranged according to the window width. I add a new album, click on it and import some photos there. But the picture are not arranged, there’s just one column with the pictures. If I click on my first album and then again on the new one, AlbumView.layout probably kicks in and the pictures are arranged as they should.
I have the same problem when I am in an album and maximize it. The photos are not rearranged until I click on a different album and then back to the old one.

Did someone experience the same behaviour?

The next update of the beta book should include the chapter on “Managing Layouts”, which has a discussion of FOX’s deferred layout mechanism. I think what your code might need is an additional call to the switcher’s recalc() method after you import the additional photos or maximize the window.

Great, I just read about recalc() on the FXRuby hompage. Great site! I’ll try it.
