[Interest] Fwd: External Application window title is missing in QWindow

[Sujan Dasmahapatra]

hi all,

further I am setting the flags as follows. I am not sure the reason, it is
chopping the header and menubar? Please check the code below.

/////////////////////////////////////////////////////////////////////////////////////////////////////////

int main(int argc, char *argv[])

{

    QApplication a(argc, argv);

    QProcess *process_fusion = new QProcess();

    process_fusion->startDetached(".\\MGL.exe  C:\\T1.nii");

    Sleep(20000);

    //0.00289917 0.28096 -0.180618 = 343    // Windows: Find HWND by
window title

    HWND id = FindWindow(NULL, L"MGL");

    if (!id)

        return -1;


    // Linux: Find Window ID by running xwininfo externally before
compiling this test

    //WId id = 0x4600085

    QTimer t;

    t.start(2500);

    // Part 1

    QWindow *window = new QWindow;

    window->setFlags(Qt::Desktop | Qt::ForeignWindow | Qt::WindowTitleHint);

    window = QWindow::fromWinId((WId)id);

    QWidget  *widget = QWidget::createWindowContainer(window);

    widget->show();

    return a.exec();

}
/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

I am setting flags as desktop, since the program is 3rd party process
so ForeignWindow and title hint. But still

my widget is missing the header text and menu. it is showing the
middle part window properly.

I am stuck with my project, I need some one's help. Please try some
body if you could help me.
