Solved: I used:
Qt Code:
  1. self.ui.SaveBtn.setText('SAVED')
  2. self.ui.SaveBtn.setStyleSheet('background-color: #99ff99; border: 2px solid #097547; ')
  3. QTimer.singleShot(1500, self.normalbtn)
To copy to clipboard, switch view to plain text mode 

The self.normalbtn is a function that returns the button to original text and color
