I would specifically like to get the active on/off name of the icon for the qPushButton. I tried to log first the icon name like on my code but the output was always empty even if I tried to programmatically make an icon, any idea how to solve this?

Here's my code for just trying to log the icon name:

qDebug() << "icon name " << ui->btnWestern1_2->icon().name(); //output: empty string

Just to verify my objective is to get the active on/off name not just the icon name but nothing works for me.

I'm using Qt 5.2.1

You can't. the icon name method is not useful in your case.

The icon is created with a filename but the filename is not stored anywhere. See this answer

You can check the way your button is created by looking at the uic ui_XXX.h file.

If you want to do it progmatically you can a property to the button containing the two icons (on/off)?

Here is a (not tested) hint: 

QStringList icons = (QStringList() << "icon1.png" << "icon2.png");

QIcon my_icon;
my_icon.addFile(QStringLiteral(icons[0]), QSize(), QIcon::Normal, QIcon::Off);
my_icon.addFile(QStringLiteral(icons[1]), QSize(), QIcon::Normal, QIcon::On);

QPushButton btn = new QPushButton(my_icon);
btn->setProperty("icons",icons);

qDebug() << btn->property("icons");

  • Thanks for the answer, but may I know when does "name" method can be useful or be functional? – Garlen Mar 22 '16 at 14:26
  • looks like it is used in case of using a theme : http://doc.qt.io/qt-4.8/qicon.html#name – bibi Mar 22 '16 at 14:37
