Okay... I had the stuff snapped to the mainwindows grid, so that's why I couldn't align it properly. I rewrote the entire thing and it works now. At least mostly. Some items will show in the middle, while most of them show at the top. Not sure why it does that, but it's workable.
And about the labels? When I do a search/filter on the labels, along with the buttons, they show up just fine without any issues. But once I put a picture in the label, they don't show anymore. Not sure why that would have anything to do with it, since it's still considered a QLabel...
Anyway, it works as good as I can get it I think. Thank you so very much for your help.
