Do you mean MainWindow icon? In that case: setWindowIcon( const QIcon & icon )

I tried with setWindowIcon(const QIcon & icon) but did not getting.Please explain briefly as to what should i do.I am working on Windows Xp OS with Qt 4.7.3.


Thanks,

Call setWindowIcon(QIcon("C:/filepath/xxxxx.png")); from the MainWindows's ctor, if this does not work make sure you have the icon file is in that path, and is of supported file type

This worked for me:

#include <QtGui>
#include <QWidget>
 
 int main(int argc, char * argv[])
 {
     QApplication app (argc, argv);
     app.setWindowIcon(QIcon("logo.png"));
 
     QWidget w;
     w.show();
 
     return app.exec();
 }

#include <QtGui>
#include <QWidget>

 int main(int argc, char * argv[])
 {
     QApplication app (argc, argv);
     app.setWindowIcon(QIcon("logo.png"));

     QWidget w;
     w.show();

     return app.exec();
 }

Make sure your file path is correct

If You use Qt-Creator, you may change icon in visual editor of form in Creator.
