      Finding nice artwork for your UI is a pain, especially if you want a consistent look.

      But Qt DLL's have a bunch of icons (also known as "pixmaps" in the Qt world) built in. They are there, so you might as well use them:

      Code (C):
      #include <QPushButton>
      #include <QStyle>
       
      QPushButton* button = new QPushButton(this);
      button->setIcon(style()->standardIcon(QStyle::SP_DirOpenIcon));
      This will create a standard Qt button, but will have a "file open" icon, suitable for use on a browse button for a save dialog, for example.

      You can see that the icon is defined as an enum as a member of the QStyle class. A full list of the icons available in Qt 5.0 is here:

      http://doc.qt.io/qt-5/qstyle.html#StandardPixmap-enum

      Hope you find this tip useful to improve the look of your own Qt applications.

      Regards, dila

      I actuelly didnt know Qt had standard icons for various standard stuff.

      so same icon, but in PyQt would be

      line 31
      Code (Python):
      from PyQt4 import QtCore, QtGui
       
      try:
          _fromUtf8 = QtCore.QString.fromUtf8
      except AttributeError:
          def _fromUtf8(s):
              return s
       
      try:
          _encoding = QtGui.QApplication.UnicodeUTF8
          def _translate(context, text, disambig):
              return QtGui.QApplication.translate(context, text, disambig, _encoding)
      except AttributeError:
          def _translate(context, text, disambig):
              return QtGui.QApplication.translate(context, text, disambig)
       
      class Ui_Form(object):
          def setupUi(self, Form):
              Form.setObjectName(_fromUtf8("Form"))
              Form.resize(400, 300)
              self.pushButton = QtGui.QPushButton(Form)
              self.pushButton.setGeometry(QtCore.QRect(114, 102, 111, 51))
              self.pushButton.setObjectName(_fromUtf8("pushButton"))
       
              self.retranslateUi(Form)
              QtCore.QMetaObject.connectSlotsByName(Form)
       
          def retranslateUi(self, Form):
              Form.setWindowTitle(_translate("Form", "Form", None))
              self.pushButton.setText(_translate("Form", "", None))
              self.pushButton.setIcon(QtGui.qApp.style().standardIcon(QtGui.QStyle.SP_DirOpenIcon))
       
       
      if __name__ == "__main__":
          import sys
          app = QtGui.QApplication(sys.argv)
          Form = QtGui.QWidget()
          ui = Ui_Form()
          ui.setupUi(Form)
          Form.show()
          sys.exit(app.exec_())
