Re: [Interest] Qt3D on Android with C++

[Jason H]

I'm not sure why this isn't considered a bug to be fixed in 5.9. It is a LTS release, after all.

Thanks, it's good to know that there will be a fix in the future. Unfortunatly I'm bound to Qt 5.9 right now.

 

Regard,

Max

Betreff: Re: [Interest] Qt3D on Android with C++

Hi,

 

createWindowContainer() has some minor issues on Android in Qt 5.9 and earlier, which unfortunately lead to not showing anything in the "embedded" window. The missing things have been added in the dev branch, so it should work in 5.10 (although I have only tested QOpenGLWindow/QVulkanWindow, not Qt3DWindow)

 

Best regards,

Laszlo

Hi,

 

I'm currently facing a problem with Qt3D and widgets on Android. My C++ application got a Qt3DWindow in a WindowContainer, so I can use Widgets for controls in this window:

Qt3DExtras::Qt3DWindow *view = new Qt3DExtras::Qt3DWindow();
QWidget *container = QWidget::createWindowContainer(view);    
QWidget *widget = new QWidget;    
QHBoxLayout *hLayout = new QHBoxLayout(widget);  
hLayout->addWidget(container, 1);

(from Basic shapes example)

 

This approach doesn't work on Android, only the widget with buttons is displayed but not the 3DWindow.

Is there a better way to add control elements to the window that works with Android?

If not, maybe I could use a Scene3D. I've got a QVector of entities (with components) I want to display there. How can I do this? I don't want to change the model, just the view.

 

Regards Max
