PyQt: How to set Combobox to Item knowing Item's text (a title)
提问by alphanumeric
Is it possible to set Combobox to an item knowing 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 a combobox to that item's index.
是否可以将 Combobox 设置为知道项目文本值的项目。我试图避免循环遍历for i in range(myCombobox.count())只是为了找到一个项目的索引，所以它可以用于将组合框设置为该项目的索引。

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-flagsas the second argument. For example, to do case-insensitivematching:
是的，有QComboBox.findText，它将返回匹配项的索引（或者-1，如果没有）。默认情况下，搜索进行精确的、区分大小写的匹配，但您可以通过传递一些匹配标志作为第二个参数来调整行为。例如，要进行不区分大小写的匹配：
index = combo.findText(text, QtCore.Qt.MatchFixedString)
if index >= 0:
combo.setCurrentIndex(index)
There is also an equivalent findDatamethod that matches by the item's data.
还有一个等效的findData方法，它与项目的数据相匹配。
