PyQt5 textbox QPlainTextEdit

Hello,
The textbox component is a very common basic component.
It is simple to use. I will show the usage from the QPlainTextEdit class in the PyQt5 library.

Some methods

setPlainText("message")

content message

move(X,Y)

the point to be positioned.

resize(width,height)

width and height values

An example:

Creator textbox method

    def textboxcreate(self):
        self.textbox = QPlainTextEdit(self)
        self.textbox.move(150,25)
        self.textbox.resize(75, 25)

And writer method

    def writetextbox(self):
        self.textbox.setPlainText("test")

Result:

from PyQt5 import QtWidgets
from PyQt5.QtWidgets import QApplication, QMainWindow, QPlainTextEdit
import sys

W_WIDTH = 400
W_HEIGHT = 250
W_X = 400
W_Y = 150


# button creator class
class CreateButton:
    def __init__(self, window, text, width, height, x, y):
        self.button = QtWidgets.QPushButton(window)
        self.button.setText(text)
        self.button.resize(width, height)
        self.button.move(x, y)

    def get_instance(self):
        return self.button


class MainFrame(QMainWindow):
    def __init__(self):
        super(MainFrame, self).__init__()
        self.init()
        self.show()

    def writetextbox(self):
        self.textbox.setPlainText("test")

    def textboxcreate(self):
        self.textbox = QPlainTextEdit(self)
        self.textbox.move(150,25)
        self.textbox.resize(75, 25)

    def init(self):
        self.resize(W_WIDTH, W_HEIGHT)
        self.move(W_X, W_Y)
        self.setWindowTitle("www.langpy.com | Python GUI Tutorial")

        self.button_question = CreateButton(self, "Write to textbox", 120, 40, 10, 10).get_instance()

        self.textboxcreate()
        self.button_question.clicked.connect(self.writetextbox)


app = QApplication(sys.argv)
