PyQt5 – Set icon size of item icon in ComboBox

In this article we will see how we can set the icon size to the item of combo box. By default there is no icon set to the icon in the combo box although we can set icon to each item with the help of setItemIcon method, sometimes there is a need for adjusting the icon size.

In order to change the icon size of items icon we will use setIconSize method.

Syntax : combobox.setIconSize(size)

Argument : It takes QSize object as argument

Action It will set icon size to the item

Below is the implementation –
