showing icons - setPixmap problem

[Tomasz]

Hello!

I've got problem with showing icons. I've read code from program where icons were used (on buttons or just somewhere on window). I've wrote code (based on that program):

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);
 
    logoLabel = new QLabel(this);
    logoLabel->setPixmap(QPixmap(":/images/icon1.png"));
    ui->layout->addWidget(logoLabel);
 
    button = new QPushButton;
    button->setIcon(QIcon(":/images/icon2.png"));
    button->setIconSize(QSize(48, 48));
    button->setFixedSize(150, 60);
    ui->layout->addWidget(button);
}

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

    logoLabel = new QLabel(this);
    logoLabel->setPixmap(QPixmap(":/images/icon1.png"));
    ui->layout->addWidget(logoLabel);

    button = new QPushButton;
    button->setIcon(QIcon(":/images/icon2.png"));
    button->setIconSize(QSize(48, 48));
    button->setFixedSize(150, 60);
    ui->layout->addWidget(button);
}

To copy to clipboard, switch view to plain text mode 

but nothing shows. No icons (button is 'empty'). Images are in directory images/ where my source code is. What I'm doing wrong?

thanks in advance
best regards

":/foo" means that the image is in the Qt Resource System. Either give an absolute path, a correct relative path or the best: use the resource system. You will find a good explanation in the docs.

Thank a lot! I've created resource file, and now it works fine!

I need to refresh that thread.
Since You've told me I'm using resource files. But sometimes I need to do to read graphics from files to put it for example into QLabel? With resource files it's easy, but sometimes I have a lot of files in one resource file, and binary is very big.

thanks in advance
best regards

just type the path without ":/" on the begining - then a graphics will be reading from files
