Thank you
What you said is done.
I only can see that Breeze is forced (maybe Qt5). Maybe it is what is write here :
"# Usage
After installing the appmenu-qt5 platform theme (to the
qt5/plugins/platformthemes/ plugin directory) for the appmenu support to work
you need to force Qt5 to use this platform theme plugin. This can be done by
setting the QT_QPA_PLATFORMTHEME environment variable to appmenu-qt5, e.g.:
QT_QPA_PLATFORMTHEME=appmenu-qt5
Now every Qt5 application that is started in the environment will export its
menu through DBus.
The source also provides a profile.d script that sets the environment to enable
appmenu-qt5 as the platformtheme by default. To install this script, simply
run qmake CONFIG+=enable-by-default
when configuring the source before
building."
I'm not clear with what is wroten (my bad).
After all, I can't find the menu into the board.
Sure I've missed something but I don't know what.
Thank you for your time.
