Thank you for quickly responding to my past problem.
Yes, now the plugin compiles without errors (or so I think). But now I do not understand how to load this plugin into gazebo. I'm trying to run setup.sh gives an error.

That's weird... I can't reproduce the issue:

loads fine for me
The undefined symbol your getting is: QTest::lastMouseTimestamp if that helps you. I don't use QTest so I'm not sure where that's coming from. Maybe your Qt install is broken or the wrong version? I have Qt 4
I am rather poorly versed in c ++ and cmake things. Actually, I also don’t understand what the problem is. And even if there is a problem with qt (apparently, the pre-installed version of qt in ubuntu is the fifth). So how do I fix the problem and install qt 4? Just sudo apt install qt4-default? Does not work.
Honestly not sure, and I can't fix the issue if I can't reproduce it. I would suggest you just read this code as an example instead of trying to use it directly.
Try making your own gui plugin according to the official gazebo tutorials, then copy in the bits of relevant code from this plugin.
Well, apparently my problem is the same with http://answers.gazebosim.org/question/19734/when-launching-gazebo-no-gui-overlay-apears-and-undefined-symbol-error-is-printed-in-terminal/. The tutorial of plugins has already been fixed and it starts up fine for me. https://bitbucket.org/osrf/gazebo/pull-requests/3041/fix-gui-plugins-on-bionic-gz9/diff here indicated 3 possible solutions. I tried to remove #include <gazebo/gui/gui.hh> from RegenerateWidget.hh and it worked the plugin started to run. Still, is there some other solution? Maybe I break something else without include gui.hh? Here two more solutions are indicated: one to change the sources of the gazebo, which could potentially break something else, and the other link against ${Qt5Test_LIBRARIES} I did not quite understand this decision. What need to do? Or I can safely not add gui .hh?
PS Sorry for bad english and bad knowledge of c ++ structure.
And yes, probably it was necessary to specify the version of ubuntu which I use earlier. Ubuntu 18.04.1 LTS

Nevermind, this is a bug with launching gazebo from vmware and has nothing to do with this. I still do get the error message but gazebo launches.
However I STILL don't get the overlay even after Gazebo launches...
Ok last post - commenting that header fixed it as indicated previously:
#include <gazebo/gui/gui.hh>closing because it currently works for me. Just tested on Ubuntu 20.04 with Gazebo 11
