pyqt qlabel displays only first char of string

Question

I want to display some string in QLabel on button click but my code only shows first char of the string. I am using following code for this

class UITesterWin         


        

Answer 1

The problem is caused because the size of the QLabel initially depends on the content of the text, and since this empty initially only takes the necessary width for a letter, the solution is to call the method adjustSize().

def test3(self, data):
    self.SecondWindow.emailIDIN.setText("hello")
    self.SecondWindow.emailIDIN.adjustSize()

Note: It is not advisable to have a variable that is named as a class since it can cause errors.
