Question

所以我得到了我正在构建的项目，我有QDialog和QTableView，QPushButton和QLineEdit。

我创建了数据来自数据库的模型，我创建了映射器以将数据从DB设置到我的LineEdit并将模型提供给QTableView。所以我尝试过并尝试将Table连接到LineEdits没有成功。

执行类似这样的操作＆＃34;当我单击该行时，它会使用该行上的数据填充LineEdit，并在编辑时保存数据＆＃34; 这是我到现在所得到的：

from ui_categorias import Ui_Dialog
from PyQt5.Qt import QMessageBox, QDialog, QDataWidgetMapper
from PyQt5.QtSql import QSqlRelationalTableModel, QSqlTableModel

class frmCategories(QDialog, Ui_Dialog):
    def __init__(self, parent = None, dbCon=None, strTblName=None):
        super(frmCategories, self).__init__(parent=None)
        self.setupUi(self)

        #Criando o Model
        self.model = QSqlTableModel(self,dbCon)
        self.model.setTable(strTblName)
        self.model.select()

        a = self.model
        self.mapFields()

    def mapFields(self):
        id, nome, descricao, comentarios,activo = range(0,5)
        '''
        Esta funcao estabekece as ligacoes entre os widgets e o modelo

        '''
        self.mapper = QDataWidgetMapper()
        self.mapper.setModel(self.model)
        self.mapper.addMapping(self.LECodigo, id)
        self.mapper.addMapping(self.LENome, nome)
        self.mapper.addMapping(self.PTEDescricao, descricao)
        self.mapper.addMapping(self.PTEComentarios, comentarios)
        self.mapper.addMapping(self.CBActivo, activo)
        self.mapper.toFirst()

        self.TVCategorias.setModel(self.model)

建立了一个可能的解决方案。

 def getInfTbl(self, row = QModelIndex): #only call parameters of that kind
    curWorkmodel = self.TVCategorias.model() #Get The current working model  
    clickedRow = row.row() # index from the item the mouse clicked #QModelIndex 
    self.mapper.setCurrentModelIndex(row) # set index of the mapper to the same as in the model
    for i in range(0,5): #1-Codigo 2-Nome 3-Descrica 4-Comentario 5-Inativo
        curWorkmodel.index(clickedRow,i) #the index the item  correspond to
