Mouse controls over Qt 3D Window

Question

I have a QWidget containing a Qt3DWindow(). I\'d like to be able to \"zoom\" in and out on a QtEntity, within the Qt3DWindow, using the mouse scroll wheel, while hovering over t

Answer 1

I'd recommend using an event filter to intercept the Qt3DWindow events. Your ModelView class can install itself as an event filter on the Qt3DWindow, detect wheel events, handle them itself, and return true to indicate that they're handled. For all other events, return false, and the Qt3DWindow will receive and process them normally.

Look at QObject::installEventfilter and QObject::eventFilter methods in the docs.
