PyQt5 - Registration Form Source Example

Introduction

PyQt5 is one of the best growing Python GUI frameworks for developing desktop and standalone applications. It is available for Linux, Windows, and Mac OS X based upon commercial as well as opensource licenses. This article is entirely focused on how the PyQt5 objects perform well to make an attractive registration form.

Python IDLE 3.7
PyQt5 contains a lot of modules for handling various widgets and program functions. The above code contains -

1. Dialog Form -QDialog
2. Frame - QFrame
3. Two Text label -QLabel
4. Four Line Edits -QLineEdit
5. Radio button -QRadioButton
6. Push Button -QPushButton

We have split the above code up into small pieces for clear understanding.

Initiation

Every program in PyQt5 should create an application object and follow by the parameter. The “sys.arg” will control the program initiation. Then, the dialog variable can hold the QDialog(Frame) with the help of QtWidgets. Next, we will need to create an object that belongs to the class (Ui_Dialog()) for accessing our methods. Then, the Dialog.show() argument is performed to execute the class as well as create a function of it.

Class and Function

• To declare the class, class name, and parameter, every function within the class is considered as an object.
• To declare function naming as setupUi(self,Dialog) which the parameter “self” represented as an instance of the class to access their attributes and methods.

Form (QDialog)

Label (QLabel)

• The EchoMode() method ensures that each character input is echoed to the screen.
• The setText() method can hold our desired textbox value.
• The font.setPointSize() argument is performed to customize the font.
• The setPlaceholderText() method is performed to placing their values, some of which are thought of shared type. It is generally useful for quick identification of Line edit objects.
