Design User Interface using QT - Help needed

[Radek]

(1) Scaling pixmaps: see QPixmap::scaled()
(2) When you setIcon() the icon is displayed on the button. The subsequent setIconSize() will change nothing.

Therefore:

QPixmap imgPixmap(fileNamePics);
QIcon   imgIcon(imgPixmap.scaled(100,80));
 
ui.PushButtonUp->setIcon(imgIcon);

QPixmap imgPixmap(fileNamePics);
QIcon   imgIcon(imgPixmap.scaled(100,80));

ui.PushButtonUp->setIcon(imgIcon);
