Can not remove border around QMenu

fire1

Hi!

Im working on a project that will run on an embedded linux device (direct to the framebuffer). On the GUI that Im building I have a QPushButton that has a QMenu that is populated with a bunch of QWidgetActions.

On my embedded device I get a border around the QWidgets and I can not remove it.

Same code on my Linux development desktop (kubuntu 18.04) I get no borders

Same code on my Windows 10 laptop I get borders but I can remove them with:
m_pMenu->setStyleSheet( "border: 0;" );

The StyleSheet code has no effect on my embedded device. Any ideas on what to do? I dont want the border to appear.

Qt Version on the embedded device is 5.12

Thanks,

After some investigation I realized that the application has different default styles depending on the host system. After adding -style Fusion to the start command on the embedded system it behaves exactly as on my dev machine.

It doesnt explain why the StyleSheet code doesnt work but it solves my issue.

Hi and welcome to devnet,

How are you starting your application on your target ?

@SGaist Thanks!

I start the application with this line:

./disp -platform linuxfb:fb0 -plugin tslib

disp is the binary.
