问题 I have the following requirement, I have a ComboBox Control (DropDownList Style) which user has to select a given value, but can not edit. Then I save it to a Database Table, and it's working fine.

(cmbDisProfile.Text = Trim(tempTb.Rows(0).Item("it_discount_profile"))) When I change the ComboBox to "DropDown Style", it works.

问题 Is it possible to change the width of a tk Combobox scrolldown bar in python 2.7? I'm not talking about the combobox width, but rather the scrollbar width on the combobox that appears when the combobox is active.

I want to display the enum in the combobox as possible selects, but I want to show the longer attribute "name" on mouseover / tooltip.
