Qt QMenu setting a stylesheet - c++

Question

I have a QMenu which I create like this.
QMenu *logoMenu = new QMenu();
I then add it to a QToolButton like so
logoButton->setMenu(logoMenu);
now I have an project.qss file which has the following stylesheet for the QMenu
QMenu#logoMenu {
background-color: #161614; /* sets background of the menu */
border: 0px solid #161614;
width: 150px;
position: absolute;
top: 50px;
}
QMenu::item#logoMenu {
background-color: transparent;
}
QMenu::item:selected#logoMenu {
background-color: #202020;
}
My problem is that the stylesheet does NOT get applies to the QMenu, I know I am loading the stylesheet correctly because I can style other widgets.
If I set the stylesheet manually like so
logoMenu->setStyleSheet("QMenu {.....}");
Here is how I create the QMenu:
logoMenu = new QMenu();
logoMenu->addAction(QString::fromUtf8("Import"));
logoMenu->addAction(QString::fromUtf8("Export"));
logoMenu->addAction(QString::fromUtf8("Help"));
logoMenu->addAction(QString::fromUtf8("Exit"));
logoMenu->setObjectName("logoMenu");
It works, no problem. Does anyone know why this happens?

Answer 1

Your Id selector is QMenu#logoMenu
It means Matches all "QMenu" instances whose object name is
"logoMenu". So you need to set object name of QMenu(
yourMenu->setObjectName( "logoMenu" ) )
Note:If QMenu is created using ui designer, Ui compiler will generate the code for yourMenu->setObjectName( "logoMenu" ). But if you are creating your own QMenu, you need to set object name explicitly to work your style type.

Judging from your comments under Ashifs answer you are missing a connection inside your Qt object tree. Try instantiating your QMenu with a parent that has a connection to the stylesheet. Probably just:
QMenu *logoMenu = new QMenu(this);
Alternatively you can set your stylesheet application global by adding it to the QApplication instance:
qApp->setStyleSheet("...");
