Are you sure? Which style is that? With some styles it's just hard to notice the difference when there's no text:

sob.text = "Button";

sob.text = "Button";

No, i'm using Oxygen style and ~QStyle::State_Enabled doesn't works for me. Maybe i must do something else?

[jpn]

Try with other style to verify it works? Well, at least it works perfectly for me.

[Apocalypse]

It doesn't works with other styles. Do you know another variants?

[jpn]

Could you show the current code of yous and explain what does "does not work" mean in your case?

[Apocalypse]

Sure. It means that ~QStyle::State_Enabled given't result and button still look like enabled. To make button disabled i use :

QStyleOptionButton sob;
        QPainter painter(this);
        sob.initFrom(this);
        sob.rect=QRect(5,55, 93,22);
	sob.state = QStyle::State_Sunken; 
	style()->drawControl(QStyle::CE_PushButton, &sob, &painter, this);
	sob.rect=QRect(5,80, 93,22);
	sob.state &= ~QStyle::State_Enabled & ~QStyle::State_Sunken;
	style()->drawControl(QStyle::CE_PushButton, &sob, &painter, this);

QStyleOptionButton sob;
        QPainter painter(this);
        sob.initFrom(this);
        sob.rect=QRect(5,55, 93,22);
	sob.state = QStyle::State_Sunken; 
	style()->drawControl(QStyle::CE_PushButton, &sob, &painter, this);
	sob.rect=QRect(5,80, 93,22);
	sob.state &= ~QStyle::State_Enabled & ~QStyle::State_Sunken;
	style()->drawControl(QStyle::CE_PushButton, &sob, &painter, this);

~QStyle::State_Sunken works and button become enabled. But i want to make it disabled. I tried to delete initFrom, but it didn't worked too;

Could you do me a favor: compile the following code and run it with "-style motif" arguments.

// main.cpp
#include <QtGui>
 
class Widget : public QWidget
{
    public:
        void paintEvent(QPaintEvent*)
        {
            QPainter painter(this);
 
            QStyleOptionButton opt;
            opt.state = 0;
            opt.text = "Disabled";
            opt.rect = QRect(0,0,100,25);
            style()->drawControl(QStyle::CE_PushButton, &opt, &painter, this);
 
            opt.state = QStyle::State_Enabled;
            opt.text = "Enabled";
            opt.rect = QRect(100,0,100,25);
            style()->drawControl(QStyle::CE_PushButton, &opt, &painter, this);
 
            opt.state = QStyle::State_Sunken;
            opt.text = "Disabled,Sunken";
            opt.rect = QRect(0,25,100,25);
            style()->drawControl(QStyle::CE_PushButton, &opt, &painter, this);
 
            opt.state = QStyle::State_Enabled|QStyle::State_Sunken;
            opt.text = "Enabled,Sunken";
            opt.rect = QRect(100,25,100,25);
            style()->drawControl(QStyle::CE_PushButton, &opt, &painter, this);
        }
};
 
int main(int argc, char* argv[])
{
    QApplication a(argc, argv);
    Widget w;
    w.show();
    return a.exec();
}

// main.cpp
#include <QtGui>

class Widget : public QWidget
{
    public:
        void paintEvent(QPaintEvent*)
        {
            QPainter painter(this);

            QStyleOptionButton opt;
            opt.state = 0;
            opt.text = "Disabled";
            opt.rect = QRect(0,0,100,25);
            style()->drawControl(QStyle::CE_PushButton, &opt, &painter, this);

            opt.state = QStyle::State_Enabled;
            opt.text = "Enabled";
            opt.rect = QRect(100,0,100,25);
            style()->drawControl(QStyle::CE_PushButton, &opt, &painter, this);

            opt.state = QStyle::State_Sunken;
            opt.text = "Disabled,Sunken";
            opt.rect = QRect(0,25,100,25);
            style()->drawControl(QStyle::CE_PushButton, &opt, &painter, this);

            opt.state = QStyle::State_Enabled|QStyle::State_Sunken;
            opt.text = "Enabled,Sunken";
            opt.rect = QRect(100,25,100,25);
            style()->drawControl(QStyle::CE_PushButton, &opt, &painter, this);
        }
};

int main(int argc, char* argv[])
{
    QApplication a(argc, argv);
    Widget w;
    w.show();
    return a.exec();
}

Yes, you are right. The button looks like disabled in motif and other squared styles.
But i need another effect. To explain what i want i made next addition into your code:

Widget()
	{
		QPushButton *button = new QPushButton(this);
		button->move(0,50);
		button->setDisabled(true);
		button->setText("Disabled PushButton");
		button->show();
		this->resize(200,200);
	}

Widget()
	{
		QPushButton *button = new QPushButton(this);
		button->move(0,50);
		button->setDisabled(true);
		button->setText("Disabled PushButton");
		button->show();
		this->resize(200,200);
	}

And i made 4 screensots off app in few styles. You can find it in attachment. Could you tell me how can i draw my button same as "Disabled PushButton"?

Try setting the palette to use "disabled" colors:

// sets the palette of this
opt.initFrom(this);
// "this" is not disabled so we switch the color group by hand
opt.palette.setCurrentColorGroup(QPalette::Disabled);

// sets the palette of this
opt.initFrom(this);
// "this" is not disabled so we switch the color group by hand
opt.palette.setCurrentColorGroup(QPalette::Disabled);
