I want to add required in my QPlainTextEdit so that when there is a blank QPlainTextEdit, the user will then be prompted that there is a blank input.

This is my sample code and I want to add required in that QPlainTextEdit.

self.plainTextEdit = QtGui.QPlainTextEdit(Form)
self.plainTextEdit.setGeometry(QtCore.QRect(110, 80, 251, 31))      
self.plainTextEdit.setObjectName(_fromUtf8("txtName"))

Thanks for some answer!.

    Do you want the QPlainTextEdit to have a placeholder that indicates that it is necessary that the QPlainTextEdit should not be empty with any message? – eyllanesc Dec 11 '18 at 19:29
  • I want that if the user will submit it, if there is a blank QPlainTextEdit, the user will prompt. – Nikko James Santillan Dec 11 '18 at 19:44

You can have some code like this:

def on_submit(self, text): #set this to trigger once the user has submitted their text
    if text == "":
        print("You must enter some text") #or any other method of prompting the user
    else:
        self.text = text #or any other variable you want the text to be stored to

Pretty self-explanatory. I can provide an example program if you wish.

Hope this helps.
