An now the same for gtk_hbox widgets ..

You can see in the screenshots of my previous post, that the "Change" buttons have the same horizontal size, as the input fields. The box layout in GTK differs from the MUI layout..

As adding the original table layouts from GTK to my mui objects went so well, I dared to add the GTK box layouts to the MUI boxes, too. This seems to be more difficult. Some times I get an infinite notify loop, which seems to be *very* difficult to find, at least for me.

If it works, it looks perfect:

The eject/insert buttons have the perfect horizontal size, the floppy leds, too. The input fields get as big as possible.

But there are those strange effects, if one hbox contains another hbox. Not always, but often..
