    No you can't, you can maybe cross-compile for linux, but not for windows(you can cross-compile for linux and install complete cygwin system on your windows, it will work, maybe....).

      how do you use the setwindowmodality?
      I need the browse window to be child and can not be reopened unless before closed

      @
      Browse * w = new Browse(dB_Setting);
      w->show;
      @

      @ Browse class

      this->setWindowModality(Qt::WindowModal);
      @

        Set it in your Browse class constructor:
        @
        Browser::Browser(QWidget *parent):QWidget(parent)
        {
        qDebug() << "input filename " << input_filename;
        this->setWindowModality(Qt::ApplicationModal);
        @

        If you really want to block event loop of main application and stay in on_loginbrowse_clicked function till user closes browse widget, make your Browse class subclass QDialog instead of QWidget, QDialog has own event loop. So your code will work well:

        @
        class Browse : public QDialog
        {
        Q_OBJECT
        public:
        ...
        @

        @
        void Login::on_loginbrowse_clicked()
        {
        // selecting a new setting.dB file
        Browse w("Setting.dB"); // Browse searching for Setting.dB
        }@

          I changed to QDialog as follows

          @

          class Browse : public QDialog
          {
          Q_OBJECT

          public:
          explicit Browse(QString input_filename, QWidget *parent = 0);
          ~Browse();
          QString OutputFileName;

          @

          @

          QString InputFileName;

          Browse::Browse(QString input_filename, QWidget *parent) :
          QDialog(parent)
          {

          @

          Then i use the following to test waiting loop of QDialog

          @
          oid Login::on_loginbrowse_clicked()
          {
          Browse * w = new Browse(dB_Setting);
          w->show();
          qDebug() << "return from browse";
          }
          @

          but when i click on browse, it prints return . It should wait till i select a file and then I should return the file name selected. I am still struggeling with it.

            OK I found it, it should be
            @
            w->exec();
            @

            and not
            @
            w->show();
            @

            but how to return the value selected?

              I've told you, if you use QDialog you can use your code:

              @
              oid Login::on_loginbrowse_clicked()
              {
              Browse w(this,dB_Setting);
              w.exec();
              qDebug() << "return from browse";
              }
              @

                Or so... :)

                You need filename value, right? Create function for getting this value:
                @
                public:
                QString getValue(){return this->filename;}

                @

                after dialog exits you can get your value like this:
                @
                void Login::on_loginbrowse_clicked()
                {
                Browse * w = new Browse(dB_Setting);
                w->exec();
                qDebug() << "return from browse: " << w->getValue();
                //and don't forget to delete this instance:
                delete w;
                }
                @

                  I have an issue over MAC. I need to show drives or at least to start with the current apppath folder

                  I used the following filter but I don't see drives, I have / only however when i loads, it shows volumes folder and the dissapears. I can not set the current path of the modelview to the current directory called set in AppPath QString.

                  @
                  dirmodel->setFilter(QDir::Dirs | QDir::Drives | QDir::NoDotAndDotDot | QDir::AllDirs);
                  @

                    Solved showing drives in MAC, since folder volumes is hidden, I used QDir::Hidden.
                    Although this is not the proper way but it is a bug in QT "Reported here":https://bugreports.qt-project.org/browse/QTBUG-6875

                    @
                    dirmodel->setFilter(QDir::Dirs | QDir::Drives | QDir::Hidden | QDir::NoDotAndDotDot | QDir::AllDirs);
                    @

                      I have another question, I created a QDialog on the fly as this, then I want to differentiate between being closed normally with the (x) button or being closed through the ok button.

                      @
                      QDialog *modifypsswdwin = new QDialog (this);
                      QLabel *newpsd1 = new QLabel(this); newpsd1->setText("New password");
                      QPushButton *modifypsswdwin_ok = new QPushButton(this); modifypsswdwin_ok->setText("OK");
                      connect(modifypsswdwin_ok,SIGNAL(clicked()),modifypsswdwin,SLOT(close()));
                      int ret=modifypsswdwin.exec();
                      @

                      I searched and found that I need to do
                      @
                      QDialog.setResult(1)
                      @

                      but the question is how to setthe result if i have only 1 line in the connect. Is it possible to write multiple commands in the slot(close)?

                      thank you

                        I found it, we should connect accept to the button as well

                        connect(modifypsswdwin_ok,SIGNAL(clicked()),modifypsswdwin,SLOT(accept()));
                        connect(modifypsswdwin_ok,SIGNAL(clicked()),modifypsswdwin,SLOT(close()));

                          I have a problem with the stylesheet. I use a style sheet file. I want to set a style sheet for this browse class from the file and not hardcoded. It works when it is hardcorded in the program but i don't know how to call it in the file. I tried #Browse and tried QDialogBox#Browse but did not work.

                          Any idea?
