Qtabwidget and webview trouble

nicky j

Hey,
So whenever I place a webview inside a tabwidget I get this error: error: [Makefile] Error 3.
I am sure im missing something super simple.
Thanks!

Look at compiler output, what written there?

Maybe you already tried that but clean and compile again. I usually do that when facing that kind of error

here is the output. I suck at making heads or tails of it.

Can you post your project file? Looks like you forgot to add webkit in the project. Code would be also nice.

I use webbview in a QTabWidget and it works very well.

yep, that what I got. I got past it though by changing some code in the .pro file.
