我们如何从QPushButton中删除图标？

Question

After begining the program I set icons on all pushbuttons. Code is like this:

QImage img;
img.load(pictureName);    
ui->pushButton_1->setIcon(QPixmap::fromImage(img));
ui->pushButton_1->setIconSize(img.size());

But after some actions I need delete pictures and set some text. How can I do it?

Answer 1

In order to delete an image you can set an empty image instead of existing one. For example:

ui->pushButton_1->setIcon(QIcon());
