Update function with timer

takoo

İs it healty ?
IS IT THE PROBLEM? (cpu)

MainWindow::MainWindow(QWidget *parent) :
   QMainWindow(parent),
   ui(new Ui::MainWindow)
{
   ui->setupUi(this);
   timer=new QTimer(this);
   timer->setInterval(500);
   timer->start();
   connect(timer,SIGNAL(timeout()),this,SLOT(update()));
}

MainWindow::~MainWindow()
{
   delete ui;
}

int s=0;

void MainWindow::update()
{
   if(s==1)
   {
       qDebug()<<"updated";
   }
   if(s==2)
   {
       qDebug()<<"updated-2";
   }
   if(s==3)
   {
       qDebug()<<"updated-3";
   }

}

void MainWindow::on_pushButton_clicked()
{
   s++;
}

Hi,

No not really healthy. update is already a non-virtual function of QWidget. Also that static s variable is not really clean by design (not to mention that one letter variables are only to be used in very specific cases)

I created own that function (update) not QWidget

SGaist

QMainWindow is a QWidget based class thus it inherits the update function from QWidget.

takoo

no no . I am making console app

SGaist

Your code snippet shows a QMainWindow based class using a designer based UI with a slot connected to a QPushButton named pushButton.

That doesn't look like a console application code.

takoo

@SGaist but this app for console

SGaist

Then why are you using GUI classes ?

takoo

just sample above codes

takoo

#include "networkprocess.h"

NetworkProcess::NetworkProcess(QObject *parent) : QObject(parent)
{
    nam = new QNetworkAccessManager();
    timer=new QTimer(this);
    url2.setUrl("ftp://myserver");
    url2.setPassword("xxx");
    url2.setUserName("xxx");
    url2.setPort(21);
    req.setUrl(url2);


    reply = nam->get(req);

    connect(reply, SIGNAL(readyRead()),this, SLOT(downloadReadyRead()));

    connect(reply, SIGNAL(finished()), this, SLOT(requestFinished()));

    timer->setInterval(500);

    timer->start();
    connect(timer,SIGNAL(timeout()),this,SLOT(updatet()));

}




void NetworkProcess::updatet()
{

       updatereply=reply;




}



void NetworkProcess::downloadReadyRead()
{

    if(updatereply->error() == QNetworkReply::NoError){
            buf = updatereply->readAll();
            if(buf=="Kapat")
            {
              qDebug()<<"tako";
            }


            if(buf=="Ac")
            {
                qDebug()<<"vural";
            }

        }
}

void NetworkProcess::requestFinished()
{

}

this is

SGaist

That update function doesn't really make sense. The reply is automatically updated while the request is being processed.

Why not use the downloadProgress signal if you want information about the downloading state of your query ?

On a side note there's the QtFTP module that you can use to access a FTP server.

takoo

I used QT5.5 . There is no qtftp.

SGaist

Please, take the time to do a bit of search: http://code.qt.io/cgit/qt/qtftp.git/

takoo

@SGaist how to I install this ?

SGaist

git clone https://code.qt.io/qt/qtftp.git
cd qtftp
qmake
make
make install
