QPixmap in QPushButton size problem

[MarkoSan]

Hi to all!

I've subclassed QPushButton and for the start I would like to resize this god damn QPixmap in subclassed QPushButton! I've been trying for a whole day and I cannot get it to work. Can someone help me?!

Like MarkoSan, I am facing the same problem using the following code;

#include <QtGui>
int main (int argc, char **argv)
{
 
	QApplication app(argc,argv);
	QWidget w;
 
	QPixmap *p=new QPixmap("plane.jpg");
	QPixmap *p1=new QPixmap(p->scaled ( 30,20, Qt::IgnoreAspectRatio, Qt::SmoothTransformation ));
	QPalette palBack;
    QBrush brush(*p1);
    brush.setStyle(Qt::TexturePattern);
    palBack.setBrush(QPalette::Active, QPalette::Button, brush);
    palBack.setBrush(QPalette::Inactive, QPalette::Button, brush);
    palBack.setBrush(QPalette::Active, QPalette::Window, brush);
    palBack.setBrush(QPalette::Inactive, QPalette::Window, brush);
 
    QBrush brush1(QColor(255, 255, 255, 255));
    brush1.setStyle(Qt::SolidPattern);
    palBack.setBrush(QPalette::Disabled, QPalette::Button, brush1);
    palBack.setBrush(QPalette::Disabled, QPalette::Window, brush1);
 
    w.setPalette(palBack);
    QPushButton *lab=new QPushButton(&w);
    lab->setGeometry(30,30,40,30);
 
 
    lab->setPalette(palBack);
	lab->setAutoFillBackground (true);
    w.show();
    w.setFixedSize(300,200);
    return app.exec();
}

#include <QtGui>
int main (int argc, char **argv)
{

	QApplication app(argc,argv);
	QWidget w;
	
	QPixmap *p=new QPixmap("plane.jpg");
	QPixmap *p1=new QPixmap(p->scaled ( 30,20, Qt::IgnoreAspectRatio, Qt::SmoothTransformation ));
	QPalette palBack;
    QBrush brush(*p1);
    brush.setStyle(Qt::TexturePattern);
    palBack.setBrush(QPalette::Active, QPalette::Button, brush);
    palBack.setBrush(QPalette::Inactive, QPalette::Button, brush);
    palBack.setBrush(QPalette::Active, QPalette::Window, brush);
    palBack.setBrush(QPalette::Inactive, QPalette::Window, brush);
       
    QBrush brush1(QColor(255, 255, 255, 255));
    brush1.setStyle(Qt::SolidPattern);
    palBack.setBrush(QPalette::Disabled, QPalette::Button, brush1);
    palBack.setBrush(QPalette::Disabled, QPalette::Window, brush1);
    
    w.setPalette(palBack);
    QPushButton *lab=new QPushButton(&w);
    lab->setGeometry(30,30,40,30);
    
    
    lab->setPalette(palBack);
	lab->setAutoFillBackground (true);
    w.show();
    w.setFixedSize(300,200);
    return app.exec();
}

To copy to clipboard, switch view to plain text mode 

By using above I am getting the black push button in spite of "plane.jpg". However It is working well for QWidget background. Any help or advice is highly respected.

I managed it to work!!!

setIconSize must be used.
