setupUi is not a member of my QT application

[JoeCFD]

Your ui file looks similar like this:
https://doc.qt.io/archives/3.3/designer-manual-16.html
Widgets
<!DOCTYPE UI><UI version="3.1" stdsetdef="1">
<class>WinIntroPage</class>
<widget class="QWidget">
<property name="name">
<cstring>WinIntroPage</cstring>
</property>

see the class tag: change it from f_pathloss to Pathloss
That is the only thing you need to do. Then recompile your code.

[lfreeman6490]

@JoeCFD I have no instances of f_pathloss, I changed them all to Pathloss

@SGaist This basically is where I started from. Every change undoes the previous one. The difference between this and the original version is the 'f_pathloss' is now just 'Pathloss'

[JoeCFD]

@lfreeman6490 said in setupUi is not a member of my QT application:

ui_Pathloss.h

do not change ui_Pathloss.h because it is generated. Change pathloss.ui or Pathloss.ui file
Your class name has to match to the name defined in
<class>*****</class> in pathloss.ui or Pathloss.ui file

[SGaist]

Depending on what that interface contains, it could be simpler to just rebuilt it from scratch and be done with it.

[lfreeman6490]

@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

[lfreeman6490]

@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
