PyQt Multiline Text Input Box

Question

I am working with PyQt and am attempting to build a multiline text input box for users. However, when I run the code below, I get a box that only allows for a single line of text to be entered. How to I fix it so that the user can enter as many lines as necessary?

   import sys
   from PyQt4.QtGui import *
   from PyQt4.QtCore import *

   def window():
       app = QApplication(sys.argv)
       w = QWidget()

       w.resize(640, 480)

       textBox = QLineEdit(w)
       textBox.move(250, 120)

       button = QPushButton("click me")
       button.move(20, 80)

       w.show()

       sys.exit(app.exec_())


   if __name__ == '__main__':
       window()

Solution

QLineEdit is a widget that provides a single line, not multiline. You can use QPlainTextEdit for that purpose.

import sys
from PyQt4.QtGui import *
from PyQt4.QtCore import *

def window():
    app = QApplication(sys.argv)
    w = QWidget()

    w.resize(640, 480)

    textBox = QPlainTextEdit(w)
    textBox.move(250, 120)

    button = QPushButton("click me", w)
    button.move(20, 80)

    w.show()

    sys.exit(app.exec_())


if __name__ == '__main__':
    window()
