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. For example: self.cmbSortOrder=ttk.Combobox(self.frame2, value=l, textvariable=self.SortOrder) self.cmbSortOrder.bind("<<ComboboxSelected>>", self.reloadList) self.cmbSortOrder.pack(side=LEFT) 回答1: you can do it using configure() : This class is used to manipulate the style database.
