[SOLVED] QIcon not get properly sets on QPushButton

Issue

I have an application of qt to sets the icon for QPushButton. The code as follows:

widget.h :

 class Widget : public QWidget
 {
     Q_OBJECT

 public:
    explicit Widget(QWidget *parent = 0);
~Widget();

 private:
     Ui::Widget *ui;
 };

widget.cpp :

 Widget::Widget(QWidget *parent) :
 QWidget(parent),
 ui(new Ui::Widget)
 {
  ui->setupUi(this);

   QImage img(":/sample");
   QPixmap scaled = QPixmap::fromImage(img).scaled( QSize(ui->pushButton->size().width(),ui->pushButton->size().height()), Qt::KeepAspectRatioByExpanding );
   QIcon icon(scaled);
   ui->pushButton->setIconSize(QSize(ui->pushButton->size().width(),ui->pushButton->size().height()));
   ui->pushButton->setIcon(icon);
 }

I having the pushbutton on ui file. But the icon not covering as fully on pushbutton. I having the pushbutton size as (100,100). I have attached the screenshot of the result:

Solution

Try passing Qt::IgnoreAspectRatio as the last argument of scaled, and see if the result fits your needs. If it doesn’t, maybe the image should be squared (i.e. same width and height).
