In this article we will see how we can create a user form in PyQt5. A user form is basically a dialog box that makes a user data entry more controllable and easier to use for the user. Sometimes while creating a large user interface application there is need of creating user form in order to get essential information.
Implementation steps : 1. Create a window class that inherits QDialog 2. Add window title and set its geometry 3. Create a QGropBox object 4. Create line edit to get the name, spin box to get the age and combo box to select the degree 5. Create a createForm method that will create a form 6. Inside the create form method, create a form layout and add rows 7. Each row should be has a label and the input method example name label and line edit for input, similarly label for degree and age and combo box and spin box for input. 8. Create a QDialogButtonBox for ok and cancel state 9. Add action to the button for acceptance and for rejection 10. If ok button is pressed just print all the information and if the cancel button is pressed window will get closed
Below is the implementation
Python3
# importing librariesfrom PyQt5.QtWidgets import *import sys# creating a class# that inherits the QDialog classclass Window(QDialog): # constructor def __init__(self): super(Window, self).__init__() # setting window title self.setWindowTitle("Python") # setting geometry to the window self.setGeometry(100, 100, 300, 400) # creating a group box self.formGroupBox = QGroupBox("Form 1") # creating spin box to select age self.ageSpinBar = QSpinBox() # creating combo box to select degree self.degreeComboBox = QComboBox() # adding items to the combo box self.degreeComboBox.addItems(["BTech", "MTech", "PhD"]) # creating a line edit self.nameLineEdit = QLineEdit() # calling the method that create the form self.createForm() # creating a dialog button for ok and cancel self.buttonBox = QDialogButtonBox(QDialogButtonBox.Ok | QDialogButtonBox.Cancel) # adding action when form is accepted self.buttonBox.accepted.connect(self.getInfo) # adding action when form is rejected self.buttonBox.rejected.connect(self.reject) # creating a vertical layout mainLayout = QVBoxLayout() # adding form group box to the layout mainLayout.addWidget(self.formGroupBox) # adding button box to the layout mainLayout.addWidget(self.buttonBox) # setting lay out self.setLayout(mainLayout) # get info method called when form is accepted def getInfo(self): # printing the form information print("Person Name : {0}".format(self.nameLineEdit.text())) print("Degree : {0}".format(self.degreeComboBox.currentText())) print("Age : {0}".format(self.ageSpinBar.text())) # closing the window self.close() # create form method def createForm(self): # creating a form layout layout = QFormLayout() # adding rows # for name and adding input text layout.addRow(QLabel("Name"), self.nameLineEdit) # for degree and adding combo box layout.addRow(QLabel("Degree"), self.degreeComboBox) # for age and adding spin box layout.addRow(QLabel("Age"), self.ageSpinBar) # setting layout self.formGroupBox.setLayout(layout)# main methodif __name__ == '__main__': # create pyqt5 app app = QApplication(sys.argv) # create the instance of our Window window = Window() # showing the window window.show() # start the app sys.exit(app.exec()) |
Output :
Person Name : Geek Degree : BTech Age : 20
