Calling one window from another

[kpks]

Hi,
My application has multiple windows:
1st window shows a log and allows user to select dynamic testing or viewing log data. This window works well so far.

If dynamic testing is chosen, the window sets up a TcpSocket to listen for incoming data. This also works.

But, at this point, I want the main window to call the Plot Window and hide itself. How do I do that?

My workaround was to launch both the windows at the start of the application with the main window on top. But, once the data starts coming over the socket, I am unable to hide the main window.
this->hide() is not working.
hide is not working.

An alternative could be, destroying/hiding two of the three widgets in the Mainwindow and replacing it with a groupbox and plot widget.
I have used Qt Creator 2.8.1 to create the windows, I have NOT hand coded it.

Thanks!

Show some code please so we can tell you what you are doing wrong or what the issue is.

showMinimized, showMaximized, show(), hide or setvisible(false) are the only options for you to manage this. As Raven said, better to give some clear code snippet. This helps us to give precise solution.

@#include "mainwindow.h"

#include "cprserver.h"
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),

{
ui->setupUi(this);
//dPlot = new Ui::dynamicPlots;

//connect(quitButton, SIGNAL(clicked()), this, SLOT(close()));

}

{
delete ui;
}

void MainWindow::on_quitButton_clicked()
{

}

void MainWindow::on_pbFiles_clicked()
{

}
void MainWindow::setUpListener()
{
const QString IP = "127.0.0.1";
const ushort port = 8100;
QHostAddress host;

host.setAddress(IP);
if (!server.listen(host,port)) {
    QMessageBox::critical(this, tr("CPR Server"),
                          tr("Unable to start the server: %1.")
                          .arg(server.errorString()));
    close();
    //qDebug() <<  "Unable to start server" << server.errorString();

}

QString ipAddress=(server.serverAddress()).toString();
qDebug () << "Server started at " << ipAddress ;//go to log
//dPlot->show();

//qsrand(QTime(0,0,0).secsTo(QTime::currentTime()));

}

void MainWindow::setPlotWindow(dynamicPlots* dp)
{
dPlot = dp;

and where do you react to new connections?

That is in the listenandwrite thread:
@#include "listenwritethread.h"

#include <QtNetwork>

listenWriteThread::listenWriteThread(int socketDescriptor, const QString &fortune, QObject *parent)
: QThread(parent), socketDescriptor(socketDescriptor), text(fortune)
{
tcpSocket = new QTcpSocket;
tcpSocket->setSocketDescriptor(socketDescriptor);

}

void listenWriteThread::run()
{
//qDebug()<<"Inside RUN!";
/if (!tcpSocket->setSocketDescriptor(socketDescriptor)) {
emit error(tcpSocket->error());
return;
}
else qDebug()<<"Ready to Roll";/
//qDebug()<<"Connection Up!";
connect(tcpSocket,SIGNAL(readyRead()),this,SLOT(analyzeThis()));
}

void listenWriteThread::analyzeThis()
{
//QTcpSOcket tcpSocket;
//qDebug()<<"In Analyze!";
QByteArray data = tcpSocket->readAll();
QString sData=QString(data);
QStringList dataList = sData.split(':');
if ((dataList.size() >= 2) && dataList[0]=="Disp")
{
bool ok;
int val = dataList[3].toInt(&ok,10);
qDebug() << " Compression Depth " << val;
}
else
qDebug() << "Data Error ! " << data;
}@

My next question is going to be how to connect thie data to the plot window for plotting. I am currently considering setting up a input vector and signalling everytime it gets 10 values full...
There must be a more elegant solution though.
