Is there an option to control the display of QGroupBox border?

Mr Pang

My ui file doesn't have custom setting of border. Both picture are fusion style, but the first one has no border.
The first one is compiled using custom toolchain and static linking with Qt.
The second one is a KDE desktop building.

I want the border to make the boundaries clear. May it relate to static linking/ or qt version?

AFAIK, the fusion style uses a qrc image as the background of QGroupBox to show the border.
According to the doc, you'll need to force initialization the resource in the case of static linking.
So try this in your main.cpp:

QApplication app(argc, argv);
Q_INIT_RESOURCE(qstyle);

Tried it but without luck.

It depends on the style you use. But you can set if you want to have drawn it flat or with a frame - see https://doc.qt.io/qt-5/qgroupbox.html

@Mr-Pang
It's theoretical 'cause I don't have a static qt to test.
Do you build the static version by yourself or use some prebuilt ones?

Here is the option

@Mr-Pang
I've thought again, you don't use the resource directly, so you don't need to initialize it.
So the problem should be with your static qt.
Would the "-no-libpng" option be the problem because you actually need to show ":/qt-project.org/styles/commonstyle/images/fusion_groupbox.png"?

Mr Pang

@Bonnie
You are right. Thanks!
