[Qt-interest] Can an Qt Application contain 2 mainwindow?

[Vincent Cai]

Thanks.



The error happens when I try to new b window in other thread.



#include "TSAUtility.h"



TSAUtility::TSAUtility(void) : QThread()

{

    DataUtt = NULL;

}



TSAUtility::~TSAUtility()

{

    this->terminate();

    this->wait();



    if(DataUtt)

    {

        delete DataUtt;

        DataUtt = NULL;

    }



    emit SignUttClose();

}



void TSAUtility::run()

{

    DataUtt = new DataUtility();//failed here



    DataUtt->show();

    while(true)

    {



    }

}



Do you know why?

Qt Application certainly can have > 1 QMainWindow. Search for bug in your code.
