Problem with QObjectPicker and Qt 5.9

gonssoruiz

Hi everyone,

First time posting. Please forgive my mistakes.

Until last week, I was using Qt 5.8. In a function I had this code:

Qt3DRender::QObjectPicker *picker1 = new Qt3DRender::QObjectPicker(m_planetEarth);
picker1->setHoverEnabled(false);
picker1->setEnabled(true);
connect(picker1, &Qt3DRender::QObjectPicker::pressed, this, &Q3DMapWidget::onPressed);
connect(picker1, &Qt3DRender::QObjectPicker::released, this, &Q3DMapWidget::onReleased);
m_planetEarth->addComponent(picker1);

It worked fine, and I was able to control my entity with the picker.

Three days ago I updated to 5.9, and the slots are not working anymore. I try to press on the picker object but there's no response.

Any ideas?

Thanks everyone in advance for your time and help.

It was solved using:

Qt3DRender::QRenderSettings *settings = (Qt3DRender::QRenderSettings*) activeFrameGraph()->parent();
if (settings)
    settings->pickingSettings()->setPickMethod(Qt3DRender::QPickingSettings::TrianglePicking);

@gonssoruiz Do you mean the slots are not called? Did you verify connect() succeeded? Like

qDebug() << connect(picker1, &Qt3DRender::QObjectPicker::pressed, this,
&Q3DMapWidget::onPressed);

qDebug

Hi,

Yes, it shows true.

The problem revealed itself when I changed from 5.8 to 5.9.

Thanks anyway.
