Answer 1

I don't think you can set arbitrarily sized images on any of the existing button classes. If you want a simple image behaving like a button, you can write your own QAbstractButton-subclass, something like:

class ImageButton : public QAbstractButton {
Q_OBJECT
public:
...
    void setPixmap( const QPixmap& pm ) { m_pixmap = pm; update(); }
    QSize sizeHint() const { return m_pixmap.size(); }
protected:
    void paintEvent( QPaintEvent* e ) {
        QPainter p( this );
        p.drawPixmap( 0, 0, m_pixmap );
    }
};

What you can do is use a pixmap as an icon and then put this icon onto the button.

To make sure the size of the button will be correct, you have to reisze the icon according to the pixmap size.

Something like this should work :

QPixmap pixmap("image_path");
QIcon ButtonIcon(pixmap);
button->setIcon(ButtonIcon);
button->setIconSize(pixmap.rect().size());
