TextEdit is a widget in PyQt5 that can be used to take input from the user and display the data to the user. It can take single-line text or multiline texts. A vertical scroll bar appears if the text does not fit into the widget. Here, we will create two TextEdit fields and a button. In the first TextEdit field, we will enter a number, and then on clicking the button, 10 will be added to that number and the result will be displayed in the second TextEdit field. TextEdit widget is provided by PyQt5 that can be installed in python using the following command.
Required Package:
pip install PyQt5
Implementation: Stepwise
Step 1: Let us first create the two TextEdit fields using PyQt5.
Python3
# Create first TextEdit where we # will enter a number. self.textEdit1 = QTextEdit() # Create second TextEdit where # result will shown. self.textEdit2 = QTextEdit() # Create a button # when clicked, result will be shown. self.btnPress1 = QPushButton("Button 1") |
Step 2: To access the number in the first TextEdit and add 10 to it, we will use the following command.
Python3
# Reading the data from the first # textEdit and adding 10 to it result = self.textEdit1.toPlainText()+10 |
Step 3: To put this result in the second TextEdit, we will use the following command.
Python3
# Displaying the result in the second textEdit. self.textEdit2.setPlainText(str(result)) |
Step 4: The above line of code will display the updated result in the second TextEdit.
Code Output
Code Implementation
Here, we are importing PyQt and creating a class TextEditDemo in which we are setting the size of a window and creating the two TextEdit boxes one is for taking an input and another is for showing a result after you click on a button. The result will be always adding 10 to the input number.
Python
# Importing PyQt from PyQt5.QtWidgets import QApplication, QWidget,\ QTextEdit, QVBoxLayout, QPushButton import sys class TextEditDemo(QWidget): def __init__(self, parent=None): super().__init__(parent) # Setting the title of the GUI self.setWindowTitle("QTextEdit") # Setting the size of the window self.resize(300, 270) # Creating the first textedit self.textEdit1 = QTextEdit() # Creating the second textedit self.textEdit2 = QTextEdit() # Creating the button self.btnPress1 = QPushButton("Button 1") # Creating a vertical box layout layout = QVBoxLayout() # Adding the first textedit into the layout layout.addWidget(self.textEdit1) # Adding the second textedit into the layout layout.addWidget(self.textEdit2) # Adding the button into the layout layout.addWidget(self.btnPress1) self.setLayout(layout) # Calling the function when the button is clicked self.btnPress1.clicked.connect(self.btnPress1_Clicked) def btnPress1_Clicked(self): ''' This function reads the data from the first TextEdit and add 10 to it. After adding the number, it displays the result in the second TextEdid. ''' result = int(self.textEdit1.toPlainText()) + \ 10 # Displaying the result in the second textEdit. self.textEdit2.setPlainText(str(result)) if __name__ == '__main__': ''' Main code that creates the GUI ''' app = QApplication(sys.argv) win = TextEditDemo() win.show() sys.exit(app.exec_()) |
