Application-Wide Stylesheet not applied on widget

jensen82

Hi,

i have subclassed widget and want to apply a application-wide stylesheet. I'm loading the stylesheet and after that i create/construct the widgets. The base widget (AUTBaseWidget from QWidget) has an implemented paintEvent() to ensure the stylesheet is applied to this widget. It works for a bunch of widget but on widgets which are childs of the centralwidget not. The color seems to be mixed with the underlying widget. But when i set the stylesheet in the constructor of my widget, it does...the correct color is displayed. What's wrong?

Some code following...

/*The style.qss that i load works for all widgets except for this*/
TopNavigationLine {
    background-color: rbg(77, 77, 77);
    min-height: 50px;
    max-height: 50px;
}

/*In the constructor it works:*/

TopNavigationLine::TopNavigationLine(QWidget *parent) :
    AUTBaseWidget (parent),
    ui(new Ui::TopNavigationLine)
{
    ui->setupUi(this);
    setLayout(ui->m_layMain);
    setObjectName("TopNavigationLine");
    ui->m_tbSelectLanguage->setObjectName("SelectLanguageButton");
    show();
    setStyleSheet("background-color: rgb(77 , 77, 77);");
}

Here are two pics:

This is the result if i load it from qss-file

This is the result if i use it in constructor

Thank you for your help!

Did you maybe forget to include Q_OBJECT macro in the header file of TopNavigationLine class?

Hi!

No, the MACRO is there. If i've had forgotten the MACRO the setStyleSheet in the constructor wouldn't work.

Thank you!

Sounds like a problem with missing/incorrect implementation of the paintEvent. Can you show it?

Btw. Calling show() from a constructor is bad manners. What if someone just wants an instance of your class without showing it (e.g. to put it in a stack or a tab)? Don't decide for them.

no, since you're not using a class name in this style declaration...

Show the definition in the QSS file before the one that isn't working. Maybe you've a parsing error in it.

@Chris-Kawa Yes, i know. The show was for testing purposes.

jensen82

@raven-worx The parsing-test was successful. No parsing error present.

Here's the Headerfile for TopNavigationLine:

class TopNavigationLine : public AUTBaseWidget {
    Q_OBJECT
    public:
    explicit TopNavigationLine(QWidget* parent = 0);
    ~TopNavigationLine();

    private:
    Ui::TopNavigationLine* ui;
};

@jensen82
you should please provide what you were asked for in order to receive proper help.

@Chris-Kawa So here's the paintEvent

void AUTBaseWidget::paintEvent(QPaintEvent* event)
{
    Q_UNUSED(event);
    QStyleOption opt;
    opt.init(this);
    QPainter p(this);
    style()->drawPrimitive(QStyle::PE_Widget, &opt, &p, this);
}

This code works for other derived widgets

i am wondering how you exactly checked for an error?
A normal CSS parser isn't appropriate here btw.

? Offline

Isn't there a superfluous semi-colon in setStyleSheet("background-color: rgb(77 , 77, 77);"); ?

jensen82

@Ian-Bray No. I think i got the error. I saved the file in UTF-8 and now it works. Strange...

Thank you all for your help!
