How to use stylesheet colors in a custom QPushButton

[VRonin]

The paint event is always painful.
Have you considered just using 4 QLabels child of the pushbutton layed out in a grid to achieve your goal?

Thanks for your answer.
To use 4 QLabels could help, I will give it a try.
Is there a posibility to read out the colors and other styles from a button to witch a stylesheet is asigned?

QPushButton::setStyleSheet(QString("background-color: red ..."));

To set the styles is very easy. But how can I read back the background-color in hovered state for example?
QPushButton::getStyle(???);

Hi
there is styleSheet() which returns the stylesheet string.

@mrjj
You're right, but then I have to analyse the complete QString by hand. I'm looking for something like this:
color = QPushButton.hover.background;

as far as I know you cannot access the
colors etc of the parsed Stylesheet.
There is no API for it. (sadly)

Ok. Then I've also no chance to get the colors of the stylesheet inside the paintEvent. Am I right?
If it does not work automatically, I've to search for an alternate solution.

Af far as I know, no.
It been ask on forum from time to time.
I never saw a solution.

Hi,

Are you planning to let somebody change the style of that button ?

@SGaist
Yes, I want to change the colors für hover, focus, pressed with a style sheet. This would be the prefered solution. If I didn't get it work I catch the mouse events and draw the colors as wanted. Changes are a little bit more complicated and not an easy exchange of the stylesheet. Do you have another idea how to solve this problem?
@VRonin
I tried your proposal with the 4 Labels in a grid. It is the same behaviour. The text color of the label has always the color specified in QLabel { color: blue; ...}. The Pseudo-States :hover, :focus, :pressed are ignored. The background-color of the state :hover is correct.

Thanks to all for your help.
I didn't get it solved with stylesheets, but I found a solution which works for me:

class SettingsButton : public QPushButton
{
    Q_OBJECT
public:
    explicit SettingsButton(QWidget *parent = 0);
    void setText2(const QString &text1, const QString &text2);
    QString getText1();
    QString getText2();

signals:

public slots:

protected:
    virtual void paintEvent(QPaintEvent *event) Q_DECL_OVERRIDE {
        QRect rect1(55,0,356,25);
        QRect rect2(55,25,356,25);
        QFont font;

        QPushButton::paintEvent(event); //To draw everything of a normal QPushButton

        m_color = QColor(Qt::white);   //same as in stylesheet QPushButton (normal)
        if( QWidget::hasFocus() ) {
            m_color = QColor(Qt::red);   //same as in stylesheet QPushButton:focus
        }
        if( QWidget::underMouse() ) {
            m_color = QColor(Qt::blue);    //same as in stylesheet QPushButton:hover
        }
        if( QPushButton::isDown() ) {
            m_color = QColor(Qt::green);   //same as in stylesheet QPushButton:pressed
        }

        //Display additional text
        QPainter painter(this);
        painter.setRenderHint(QPainter::Antialiasing, true);
        painter.setPen(m_color);
        font = painter.font();
        painter.setFont(QFont(font.family(), font.pointSize(), QFont::Bold));
        painter.drawText(rect1, Qt::AlignLeft|Qt::AlignVCenter, firstText);
        painter.setFont(QFont(font.family(), font.pointSize(), QFont::Normal));
        painter.drawText(rect2, Qt::AlignRight|Qt::AlignVCenter, secondText);
    }

private:
    QString firstText;
    QString secondText;
    QColor m_color;
};
