Python GUI Development with PyQt5

This is our tenth video in Python GUI Development with PyQt5, in this video i want to show you how to Create QCheckBox With Toggled Signal In PyQt5

What Is QCheckBox ?

The QCheckBox widget provides a checkbox with a text label.
A QCheckBox is an option button that can be switched on (checked) or off (unchecked). Checkboxes are typically used to represent features in an application that can be enabled or disabled without affecting others,
but different types of behavior can be implemented. For example, a QButtonGroup can be used to group check buttons logically, allowing exclusive checkboxes. However,
QButtonGroup does not provide any visual representation.
Whenever a checkbox is checked or cleared it emits the signal stateChanged(). Connect to this signal if you want to trigger an action each time the checkbox changes state. You can use isChecked() to query whether or not a checkbox is checked.
In addition to the usual checked and unchecked states, QCheckBox optionally provides a third state to indicate "no change". This is useful whenever you need to give the user the option of neither checking nor unchecking a checkbox. If you need this third state, enable it with setTristate(), and use checkState() to query the current toggle state.
Just like QPushButton, a checkbox displays text, and optionally a small icon. The icon is set with setIcon(). The text can be set in the constructor or with setText(). A shortcut key can be specified by preceding the preferred character with an ampersand

Thankyou for your videos. Clear and easy to understand and implement. Can you please create some Project based videos too, related to PyQt5 stating its applications in real world, with different options combined together(eg. using radio, checkbox, slider etc in one application itself)
