New Creator Problem
I have added two subclasses of QWidget and promoted Widget placeholders to those classes and named them canvas and slider. However, when I try to reference them in MainWindow, namely ui->canvas. I get no member named canvas in Ui::MainWindow. I have been doing this for a long time. What gives.

@ofmrew I saved what I had, closed Qt and then deleted the build directory. You guessed it, it now works. This is illogical and it is silly to need to do this. I reported the problem with autocomplete for #include in the last version, it seems that it still has that and now this!
@ofmrew Everything in ui-> is autogenereated code, you need to build first so the code gets generated.
@jsulm Sorry, I thought I had done that.
