Is it possible to set QComboBox to an item knowing only an item's text value? I am trying to avoid looping through for i in range(myCombobox.count()) just to find an item's index so it could be used to set the current index.

A combobox can be created with the QComboBox class. Items are added using the class method addItem, followed by a string parameter. Sometimes its called a listbox, as it shows a list of items a user can select from. If you want a user to choose from a set of items, the listbox is the best option.
A combobox can be populated using the insert functions, insertItem() and insertItems() for example. Items can be changed with setItemText(). An item can be removed with removeItem() and all items can be removed with clear().
Yes, there is QComboBox.findText, which will return the index of the matched item (or -1, if there isn't one). By default, the search does exact, case-sensitive matching, but you can tweak the behaviour by passing some match-flags as the second argument. For example, to do case-insensitive matching:
index = combo.findText(text, QtCore.Qt.MatchFixedString) if index >= 0: combo.setCurrentIndex(index) There is also an equivalent findData method that matches by the item's data.
