How to show QLabels

[Pavel Abrosimov]

You could be right. But the class in the source code has inheritance from QWidget.
The QLabels didn't show with that properly as it was only first letter was seen from any label.

The trick with QPainter did it's job - there is a loop for all required text and painter draws it:

painter.drawText(x, y, text);

Draw text with different color and different size is not a big deal. With color seems to be fine - just call painter.setPen(color). And after - painter.setFont(font)

But now I am facing new problems - how can I make the window with all that information to be transparent?

Best regards

So what are the labels for if you're drawing the text manually?

To me the problem seems to be caused by the fact that you are not using layouts and that you completely ignore setting geometry of the labels, so it's quite obvious you see nonsense.

#include <QLabel>                                                                                                                                                                 
#include <QApplication>                                                                                                                                                           
 
 
int main(int argc, char **argv){
  QApplication app(argc, argv); 
  QWidget w;                    
  for(int i=0;i<10;i++){        
    QLabel *l = new QLabel(&w);
    l->setText(QString("Label %1").arg(i+1));
    l->setGeometry(i*20, i*20, l->sizeHint().width(), l->sizeHint().height());
  }
  w.show();
  return app.exec();
};

#include <QLabel>                                                                                                                                                                 
#include <QApplication>                                                                                                                                                           


int main(int argc, char **argv){
  QApplication app(argc, argv); 
  QWidget w;                    
  for(int i=0;i<10;i++){        
    QLabel *l = new QLabel(&w);
    l->setText(QString("Label %1").arg(i+1));
    l->setGeometry(i*20, i*20, l->sizeHint().width(), l->sizeHint().height());
  }
  w.show();
  return app.exec();
};

As you said, there is no need in QLabels. And they are all taken away. There is just a sort of vector with all QStrings needed.

How it is possible to make the background of the window transparent, but the text must be visible on it?

Please search the forum. The issue has been brought up multiple times recently.
