Cannot open include file: 'QWebView': No such file or directory

Question

I have followed the instructions on the following page:

http://qt-project.org/wiki/Open_Web_Page_in_QWebView

I added QT += webkit in my pro file and ran qmake, then clean all and compile again. I still get:

error: C1083: Cannot open include file: 'QWebView': No such file or directory

when I add #include <QWebView> in header and cpp file. Any ideas?

Answer 1

I had to add QT += webkit webkitwidgets as well in the pro file for it to work.

Answer 2

I had to add the libqtwebkit-dev package for my app to compile.

Answer 3

I ran into the same issue on Kubuntu 18.10. My development environment was for Qt5 and I needed to install

libqt5webkit5-dev

apt install libqt5webkit5-dev

Answer 4

It works fine for me, on a mac with homebrew install.

Open the Makefile generated by qmake

There should be a variable called INCPATH, and one of the paths listed should end with /include.

List this directory and make it exists, and the many QXXXX directories and header files are present (in particular QWebKit).

If everything seems to be ok, please detail how you are naming the files and what commands are you using to generate the makefile with qmake and then compiling.
