PyQt5 QColorDialog – Accepting the color

In this article we will see how we can accept the QColorDialog widget. Accepting hides the modal dialog and sets the result code to accepted, it is same when user press ‘OK’ button.

This method calls the finished signal

In order to do this we use accept method with the QColorDialog object

Syntax : dialog.accept()

Argument : It takes no argument



Return : It returns None

Below is the implementation

Output :

Note : In this implementation we didn’t execute the color dialog because we set the current color and accept the color programmatically will make it selected color instead of white which is default
