How can i store the values?

[lordumuzca]

I need to be store in horizontal slider values and i want to write when i push the button.but i cant store the values.if i store the values , i'll use in pushbutton. my output must be "value1,value2,value3".

#include "dialog.h"
#include "ui_dialog.h"
#include <QSerialPort>
#include <QDebug>
#include <QtWidgets>
#include <QString>


QSerialPort *serial;
Dialog::Dialog(QWidget *parent) :
    QDialog(parent),
    ui(new Ui::Dialog)
{
    ui->setupUi(this);
    serial = new QSerialPort(this);
    serial->setPortName("COM3");
    serial->setBaudRate(QSerialPort::Baud9600);
    serial->setDataBits(QSerialPort::Data8);
    serial->setParity(QSerialPort::NoParity);
    serial->setStopBits(QSerialPort::OneStop);
    serial->setFlowControl(QSerialPort::NoFlowControl);
    serial->open(QIODevice::ReadWrite);

    connect(serial,SIGNAL(readyRead()),this,SLOT(serialReceived()));



}

Dialog::~Dialog()
{
    delete ui;
     serial->close();
}




void Dialog::on_degree_horizontalSlider_valueChanged(int value)
{

    Dialog::updateServo(QString("%1,").arg());

}

void Dialog::on_delay_horizontalSlider_valueChanged(int value)
{
    Dialog::updateServo(QString("%1,").arg(value));
}

void Dialog::on_rnumber_horizontalSlider_valueChanged(int value)
{
    Dialog::updateServo(QString("%1").arg(value)); /*??*/
}

void Dialog::on_pushButton_clicked()
{
    //????
}

void Dialog::updateServo(QString command)
{
    if(serial->isWritable()){
        serial->write(command.toStdString().c_str());

    }else{
        qDebug()<<"Couldn't write to serial";
    }

}

void Dialog::serialReceived(){


        QByteArray ba;
        serial->waitForReadyRead(10);
        ba=serial->readAll();
        qDebug()<<ba;

}

I didn't understand precisely what and where you want some values to store, but a general approach in such cases, as I think, is to sub-class the parent you need and add suitable fields.

Hi,

If I understand things correctly, you want to always send the value of the three sliders ?

If so, you can drop the four on_XXX_ slots and connect all relevant widgets to updateServo from which you remove the parameter. Then:

id Dialog::updateServo()
{
    if(serial->isWritable()){
        QString cmd("%1,%2,%3").arg(ui.degree_horizontalSlider.value())
                               ui.arg(delay_horizontalSlider.value()
                               ui.arg(rnumber_horizontalSlider.value()
        serial->write(cmd.toUtf8());

    }else{
        qDebug()<<"Couldn't write to serial";
    }

}
