Problem with selecting next/previowus record

That is why I was requesting a minimal runnable script to that would show your issue.

From the looks of it, you can use QTableView's currentIndex to grab the currently selected index.

From a code point of view, you should refactor your NextOne function. It's hard to read and reason about because you are not using meaningful variable names. Also, NextOne does not follow python best practices for function naming.

Here a simplified and clearer version:

def select_next_row(self):
    selection_model = self.dlg.tableView_3.selectionModel()
    current_index = selection_model.currentIndex()
    if current_index.isValid():
          next_index = current_index.siblingAtRow(current_index.row() + 1)
          if next_index.isValid():
              selection_model.select(next_index, QItemSelectionModel.ClearAndSelect | QItemSelectionModel.Rows)

Unless you want to implement wrapping from the bottom to the top of your table view, there's nothing more that method should do.

Thnaks, but still change only to first next.
What kind of code (for which funtion) you want to see to find better solution for my problem?

@Karoluss96 said in Problem with selecting next/previowus record:

What kind of code

A runnable script as small as possible which shows this behaviour.

Function for showing records in tableView looks that:

 def present_data(self):
            query = QSqlQuery(db)
            query.exec_(Zap)
            global ier
            ier= ['ID','TERYT'] #and more atributtes
            self.model4.clear()
            self.model4.setHorizontalHeaderLabels(ier)
            x = 0
            while query.next():
                x += 1
                self.model4.setItem(x, 0, QStandardItem(str(int(query.record().value(ier[0])))))#ID
                self.model4.setItem(x, 1, QStandardItem(str(query.record().value(ier[1]))))#code of ad level 1
#next atributtes in table 'ier'
 self.dlg.tableView_3.clicked.connect(self.SelekcjaRzedu)

and next:

def selectRow(self):
                dane=self.dlg.tableView_3.selectionModel().currentIndex()
                rzad=dane.row()
                self.dlg.label_53.setText(str(self.dlg.comboBox_9.currentText()))#administrative level 2 
                woj= ((self.dlg.comboBox_3.currentText())[0:-5]).lower()#administrative level 1 
                a1=dane.siblingAtRow(rzad).siblingAtColumn(0).data()#ID
                b2=dane.siblingAtRow(rzad).siblingAtColumn(1).data()#code of ad level 1
#next attributes...
if woj !='do':#not put NULL in labels
                    self.dlg.label_82.setText(woj)
                else:
                    self.dlg.label_82.setText('')
                if a1 != 'NULL':
                    self.dlg.label_32.setText(str(a1))
                else:
                    self.dlg.label_32.setText('')

@Karoluss96 This is not a RUNNABLE script...

Karoluss96

you want the run function?

Karoluss96

the run function to open this gui looks that:

def run(self):
global TERYT, qmlPath, mainPath, controlPath, db, connectionParam, schema, password, database, port, host, oznaczenieZmiany

    # paths to files
    qmlPath = Path(QgsApplication.qgisSettingsDirPath())/Path("python/plugins/SystemBDOT10k/BDOT10k_QML/")
    mainPath = Path(QgsApplication.qgisSettingsDirPath())/Path("python/plugins/SystemBDOT10k/")
    controlPath = Path(QgsApplication.qgisSettingsDirPath())/Path("python/plugins/SystemBDOT10k/Kontrole/")
    
    self.dlg = SystemBDOT10k_dialog()
    self.dlg.setWindowFlag(Qt.WindowMinimizeButtonHint, True)
    self.dlg.rejected.connect(self.close)
    
    #get parameters from file SystemBDOT10k.ini 
    config = configparser.ConfigParser()
    config.read(str(mainPath)+'/SystemBDOT10k.ini')
    connectionParam = config['oracle']
    schema = (base64.b64decode((connectionParam['Schema']).encode('utf-8'))).decode('utf-8')
    password = (base64.b64decode((connectionParam['Password']).encode('utf-8'))).decode('utf-8')
    port = connectionParam['Port']
    host = connectionParam['Host']
    database = connectionParam['Database']
    markChange = config['MainSettings']['markChange']

    # connect to data base
    db = QSqlDatabase.addDatabase("QOCISPATIAL")
    db.setDatabaseName(host + ':' + port + '/' + database)
    db.setUserName(schema)
    db.setPassword(password)
    ok = db.open()
    self.operetionOnData()
    
    
    self.dlg.comboBox.currentTextChanged.connect(self.chooseStatus)
    
    self.statusPowiatu()
    self.chooseStatus()
    
    # selecting QML folders to comboBox
    path = os.listdir(str(qmlPath).replace("\\","/"))
    length = len(path)
    for i in range(length):
        self.dlg.comboBox_1.addItem(path[i])
        
    self.dlg.show() 
    result = self.dlg.exec_() # Run the dialog event loop

@Karoluss96 Runnable means in this case: something somebody can download/copy from here and drectly execute to reproduce your issue.

This is a QGIS plugin with GUI, so it isn't possible to put it outside of QGIS program (which you can download for free here: https://qgis.org/pl/site/forusers/download.html)
