PyQt5 QColorDialog – Custom Color Count

In this article we will see how we can get the number of custom colors supported by QColorDialog widget. Custom colors the color made by the user they can be set at the run time with the help of mouse although we can add custom color programmatically with the help of setCustomColor method, by default all custom colors are white. We can get the custom color with the help of customColor method.

Below is how the custom color in color dialog looks like

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

Syntax : dialog.setCount()

Argument : It takes no argument



Return : It returns integer

Below is the implementation
