Minimize to Tray

[QT8seven]

I have searched all around and cannot get this to work! Attempting to call hide() within changeEvent in a way such as:

void AppWindow::changeEvent(QEvent *event)
{
    if (event->type() == QEvent::WindowStateChange)
        if(isMinimized())
        {
            hide();
        }
    QMainWindow::changeEvent(event);
}

void AppWindow::changeEvent(QEvent *event)
{
    if (event->type() == QEvent::WindowStateChange)
        if(isMinimized())
        {
            hide();
        }
    QMainWindow::changeEvent(event);
}

To copy to clipboard, switch view to plain text mode 

causes the window to white-out rather than hide. Does anyone know why this happens or how to fix this? I am attempting to use a tray-icon on minimize, but without being able to hide will never have much success. Currently, the only way I can work around this is to use a singleShot timer to call the hide.

Try this way (at least it works fine in our projects):

if (event->type() == QEvent::WindowStateChange && windowState() & Qt::WindowMinimized)
    QMetaObject::invokeMethod(this, "hide", Qt::QueuedConnection);

if (event->type() == QEvent::WindowStateChange && windowState() & Qt::WindowMinimized)
    QMetaObject::invokeMethod(this, "hide", Qt::QueuedConnection);
