[sevketk]

Hi . my code is

    label = new QLabel(this);
    label->setGeometry(0,0,142,192);
 
    label->setPixmap(back);
    setStyleSheet("background-color:red"); // so far so good 
    // but i want to change size pixmap after load (for example onclick event)
    label->pixmap()->scaled(QSize(100, 297));
    label->repaint();
    // noting change size with or another

back.load(":/images/back.png");
    label = new QLabel(this);
    label->setGeometry(0,0,142,192);

    label->setPixmap(back);
    setStyleSheet("background-color:red"); // so far so good 
    // but i want to change size pixmap after load (for example onclick event)
    label->pixmap()->scaled(QSize(100, 297));
    label->repaint();
    // noting change size with or another

I wantto change pixmap width after loading in label , because I use two pixmap for one label. I want to the pixmap of label inside to change , Whichever it can. I mean , what's inside pixmap that moment
in other words, I want to change size which pixmap is present in the label, without knowing what pixmap is...
