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.

有帮助吗?

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.
