Creating a class object "wrapper" inside the mainwindow constructor makes the main window not visible [SOLVED]

ion_knight

Currently trying to create a QWidget inside mainwindows constructor, however once I create the object inside the mainwindow constructor the mainwindow never shows. Any files not listed are identical to the default.

Mainwindow.cpp
@MainWindow::MainWindow(QWidget *parent)
: QMainWindow(parent)
{

QPalette p(palette());
p.setColor(QPalette::Background, Qt::lightGray);
this->setAutoFillBackground(true);
this->setPalette(p);
this->setWindowTitle(QApplication::translate("toplevel", "CCTV"));

mplayer_wrapper *cameras = new mplayer_wrapper("rtsp://169.254.133.191/output","rtsp://169.254.133.193/output");
centralWidget()->layout()->addWidget(cameras);

}
@

I have commented out everything inside the constructor of mplayer_wrapper so that it's only creating a black window.

@mplayer_wrapper::mplayer_wrapper(QString cam_1, QString cam_2,QWidget *parent) :
QWidget(parent)
{
QPalette p(palette());
p.setColor(QPalette::Background, Qt::black);
this->setAutoFillBackground(true);
this->setSizePolicy(QSizePolicy::Expanding, QSizePolicy::Expanding);
this->setPalette(p);
this->setMinimumSize(720,576);
this->setMaximumSize(1440,576);
}@

If anyone has an idea why this is failing to launch I would be very grateful. As can't see where I am going wrong at the moment as the only thing I don't have is that I didn't create a ui form during project creation (as I am doing all my layout in code so thought that wasn't necessary). Hopefully someone can point me in the right direct before I pull my hair out.

Hi,

Don't you by any chance rather have a crash ?

@centralWidget()->layout()->addWidget(cameras);@

You didn't' set any central widget, at least from the code your posted.

@setCentralWidget(cameras);@

Should do what you want.
