QSortFilterProxyModel不適用不區分大小寫

Question

正如我已經將QSortFilterModel子類化爲能夠在QListView中搜索多個coloumns，CaseInsensitive選項不再起作用。我試圖應用它如下：

class CustomSortFilterProxyModel(QtCore.QSortFilterProxyModel): 
    def __init__(self, parent=None): 
     super(CustomSortFilterProxyModel, self).__init__(parent) 
     self.filterString = '' 
     self.filterFunctions = {} 
     self.setFilterCaseSensitivity(QtCore.Qt.CaseInsensitive) #Applied here 



    def setFilterString(self, text): 

     self.filterString = str(text) 
     self.setFilterCaseSensitivity(QtCore.Qt.CaseInsensitive) #And applied here 
     self.invalidateFilter() 

    def filterAcceptsRow(self, row_num, parent): 

     self.filterColumns = [1,3]  
     model = self.sourceModel() 
     row = model.row(row_num) 
     tests = [self.filterString in row[col] for col in self.filterColumns] 

     return True in tests 

我的搜索字符串是如何區分大小寫的？

您在那裏設置的靈敏度僅適用於默認的filterAcceptsRow實現。如果你重寫它，你需要這個自己處理，這樣做是這樣的：

return any(self.filterString.casefold() in row[col].casefold() for col in self.filterColumns)) 

（見str.casefold docs）
