PyQt5 Combo Box – Different border size when it is editable and get pressed Last Updated : 03 May, 2020 Comments Improve Suggest changes Like Article Like Report In this article we will see how we can set different border width to the combo box when it is editable and get pressed, when we set border to the combo box it is of same color for all the sides although we can change color of each sides respectively. Different border width will only appear combo box is editable and combo box is pressed Note : Combo box can be made editable with the help of setEditable method In order to do so we have to change the style sheet associated with the combo box below is the style sheet code Code 1 QComboBox::editable:pressed { border : solid black; border-width-top : 1px; border-width-right : 5px; border-width-bottom : 2px; border-width-left : 10px; } Code 2 QComboBox::editable:pressed { border : solid black; border-width : 1px 5px 2px 10px; } Both code perform similar task just code 1 is extended version of code 2.
