Hey Bo,
Just wanted to share with you some progress.
Actually Qt makes it really simple. I was amazed I could do it with a
just 5 lines of code. (Qt ROCKS!)
Right now, I just have a problem. The plugin window opens and closes
perfectly. But once open, if I delete the plug in from the host and the
QApplication is deleted, it crashes. Still can't figure it why.
See below my simple solution for this case. I problably know it
yourself. I'm sharing it anyway.
bool IVstWrapperEditor::open(void *ptr)
{
AEffEditor::open(ptr);
if (!window)
{
window = QWindow::fromWinId((WId)ptr);
view = new QQuickView(window);
view->setSource(QUrl(QStringLiteral("qrc:/main.qml")));
view->rootContext()->setContextProperty("controller", _controller);
view->show();
return true;
}
return false;
}
void IVstWrapperEditor::close()
{
if (window)
{
qDebug() << "destroying view";
view->deleteLater();
view=0;
qDebug() << "destroying window";
window->deleteLater();
window=0;
}
AEffEditor::close();
}
Regards,
Nuno

In my case I have a related app which opens the plugin.
The host provides a window handle to the plugin.
I was trying to make that handle into a QWidget with the following code:
MyWindow::MyWindow(void* ptr) :
QWidget(0)
{
HWND w = (HWND) ptr;
setGeometry(QRect(0,0,640,480));
QPalette Pal(palette());
// set black background
Pal.setColor(QPalette::Background, Qt::black);
setAutoFillBackground(true);
setPalette(Pal);
create((WId)w, false, false);
}
The problem is that two windows appear, the one the host provides and
the one created by QWidget.
It seems that the create call is not working as intended.
MyWindow subclasses QWidget in order to call the create method since
it’s protected.
Do you have any clue why this technic isn’t working?
Thanks,

Thanks for sharing your code.
I will try and give some feedback.
Any thoughts regarding the initial approach? Is there any reason for you
not having followed that path?
My application inserts an overlay over a complete unrelated
application (the pokerstars or bet365 poker clients actually), so
this is the only approach that can work.
