SU_Shadow

Hi. Can anybody help me. When i using in style sheet of QTableWidget some like this
QHeaderView::section
{
background-color: rgb(85, 0, 0);
}
I get all row headers are red (no meter what color i set in styles heet)

mrjj

Hi and welcome
if you change to
background-color: rgb(0, 0,255);
And select menu
Build->clean all
and
Build->rebuild all

It must be a blue color. else u set style sheet somewhere else or have something that
overrules this one.
like
Qwidget
{
background-color: rgb(85, 0, 0);
}

No changes. A get red row headers (in editor i see blue row headers, but in runtime its red)

mrjj

@SU_Shadow
If it changes when u run program,
it must mean u also set StyleSheet in code.
Or set stylesheet on a parent where it also affects
the childs.
They are cascading

I create empty QWidget project and add QTableWidget on main widget. Then i add button. On button i connected slot which excute :
ui->tableWidget->setStyleSheet("QHeaderView::section { background-color: rgb(0, 0,255);}");
After form loads i get normal (default) background of rows headers, but when i press button i get row headers red (not blue)

@SU_Shadow
Also you get no text?? (!)

It seems stylesheets are somehow broken in your Qt.

Did you compile Qt yourself?

What version of Qt ?
Looks like a linux platform?

SU_Shadow

Platform fedora 22. Qt 4.8. When i greate qt5 qwdiget application ( or when i change kit from qt4 to qt5 and make clean all and rebuild all) all look's fine. But on qt4 i get this error.

mrjj

@SU_Shadow
ok. must be a bug in 4.8 then. ?
Maybe to that platform.
Not heard about it before.
I have 5.6 only so cant test.

Found some solution. Think problem in QStyle of application on qt 4.8 under fedora (plasma DE). When i write in main some like

    QApplication a(argc, argv);
    a.setStyle(new QWindowsStyle);
    MainWindow w;
    w.show();

All works fine.

mrjj

ok !?
good found :)
