What palette role/attribute sets the line color of QFrame "setLineWidth" ?

edmh

Hello -
I am looking to change the color of the line drawn around the edge of a QFrame using this code:

QFrame* frameA = new QFrame(centralWidget)
frameA->setFrameShape(QFrame::Box);
frameA->setFrameShadow(QFrame::Sunken);
frameA->setLineWidth(2);
frameA->setMidLineWidth(4);

If I do this:
QBrush brush1(QColor(127, 127, 127, 255));
brush1.setStyle(Qt::SolidPattern);
palette.setBrush(QPalette::Active, QPalette::Mid, brush1);

Then the line drawn for "setMindLineWidth" is grey, as expected.
But the line drawn from 'setLineWidth(2)' is always white. How do I change that color?

And yes, I have don this:

QBrush brush3(QColor(255, 0, 0 255));
brush.setStyle(Qt::SolidPattern);
palette.setBrush(QPalette::Active, QPalette::WindowText, brush3);
palette.setBrush(QPalette::Active, QPalette::Text, brush3);

I am using Qt5 and I do NOT want to use style sheet.
Operating system is Linux / Xorg

Thanks

Hi,

I'm not sure I understand (a screenshot of your current result would be helpful), but I'm guessing the shadow color is what you mean.

From QFrame documentation:

QFrame::Sunken : the frame and contents appear sunken; draws a 3D sunken line using the light and dark colors of the current color group

So try this:

QFrame* frameA = new QFrame();
frameA->setFrameShape(QFrame::Box);
frameA->setFrameShadow(QFrame::Sunken);
frameA->setLineWidth(2);
frameA->setMidLineWidth(4);

QBrush brush1(QColor(127, 127, 127, 255));
brush1.setStyle(Qt::SolidPattern);

QPalette palette=frameA->palette();
//shadow color, dark and light palette roles
palette.setBrush(QPalette::Active, QPalette::Light, brush1);
palette.setBrush(QPalette::Active, QPalette::Dark, brush1);

//mid line color
palette.setBrush(QPalette::Active, QPalette::Mid, brush1);
frameA->setPalette(palette);

frameA->show();

Is this the result you're looking for?

@Abderrahmene_Rayene said in What palette role/attribute sets the line color of QFrame "setLineWidth" ?:

palette.setBrush(QPalette::Active, QPalette::Light, brush1);

Yes, thank you.
So the answer to my question is

alette.setBrush(QPalette::Active, QPalette::Light, brush1);
palette.setBrush(QPalette::Active, QPalette::Dark, brush1);
