[提问]QVtkWidget镶嵌到QWidget中,原本的QWidget::nativeEvent中的部分事件就无法响应 [复制链接]

我做个QVTKWidget窗口类，想镶嵌到QMainWidget主界面中。

但是一旦把QVtkWiget父窗口设置为主窗口界面时，
原本QMainWIdget主界面中nativeEvent事件部分消息(WM_NCHITTEST)就无法响应，
而且所有控件的hover、pressed样式也失效。

如果把QVtkWidget窗口父窗口设置为空，主界面就会恢复正常。

是不是QVTKWidget将一些消息给拦截了？求各个大佬帮忙


void VTK3DModelEditor::initWindowVtk()
{
//     QVTKWidget vtkWidget = new QVTKWidget ();
//     vtkWidget ->setWindowFlags(Qt::Widget | Qt::WindowStaysOnTopHint);

    QVTKWidget vtkWidget = new QVTKWidget (this);
    auto hlayout = new QHBoxLayout(ui.widget_vtk);
    hlayout->addWidget(m_vtkWidget);
}


bool VTK3DModelEditor::nativeEvent(const QByteArray &eventType, void *message, long *result)
{
    MSG* msg = (MSG*)message;
    switch (msg->message) {

    case WM_NCHITTEST://此消息就无法响应
    {
        initMousePos();
        switch (m_mousePos)
        {
