Display a Java UI application in a QWidget frame

giesbert

Hi,
I'm working in a bigger project in the area of electrical network control centers. We have a huge hybrid application with different programming languages (C, C++, Qt, Java, Fortran, ...).
Our Main UI is Qt and Web Page based (displayed in Qt). Now we have to integrate a Java Based UI somehow and it should be displayed in a QWidget frame.
Is it possible to bring a Java Based application to render in a Qt Widget somehow? I know, long time ago, ther was QtJambi, but that seems to be dead and is still for Qt 4.X and the wrong way round.

Regards

Giesbert

hi
You might be able to grab it with

HWND hwnd = FindWindowEx(...) // find the java window
QWidget *widget =Widget::createWindowContainer(QWindow::fromWinId((WId)hwnd));

to wrap it into a widget but Im not sure about what happens to the events.

This is purely speculation. though.

Hi,

Yeah that would eventually work on windows, we have to try it. I completly forgot this feature on windows, shame on me....
Thanks a lot, we will give it a try...

Sadly , I know of no cross platform way to try it :(
