setupUi is not a member of my QT application

@SGaist Yeah I think I might just do that. I've been at this all day. Thanks for trying to help. I appreciate it @JoeCFD

You can see where I use TestWidget in .cpp, .h and .ui. They have to be the same.

@JoeCFD I have it all the same except for one line in my pathloss.ui file. It has my widget class as a "QFrame" and it has to be changed in the design mode it says

<?xml version="1.0" encoding="UTF-8"?>
<ui version="4.0">
 <author>free</author>
 <class>pathloss</class>
 <widget class="QFrame" name="pathloss">
  <property name="geometry">

[JoeCFD]

use upper case
<class>pathloss</class> ===> <class>Pathloss</class>
<widget class="QFrame" name="Pathloss"> <====not critical

@JoeCFD I was able to edit the xml and change my widgets section to be a QWidget and I'm dealing with some other errors from here. Thanks
