Detailed Description¶

Note

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.

property channelNameᅟ: str¶

Access functions:

channelName()
setChannelName()
Signal channelNameChanged()

__init__([parent=None])¶

Parameters:: parent – QNode

callback()¶

Return type:: QAnimationCallback

channelName()¶

Return type:: str

setChannelName()

Getter of property channelNameᅟ .

channelNameChanged(channelName)¶

Parameters:: channelName – str

Notification signal of property channelNameᅟ .

setCallback(type, callback[, flags=Qt3DAnimation.QAnimationCallback.OnOwningThread])¶

Parameters:

type – int
callback – QAnimationCallback
flags – Combination of Flag

Associates a callback object with this channel mapping.

Such mappings do not have to have a target object and property name. When the callback object is set, every change in the animated value will lead to invoking the callback’s valueChanged function either on the gui/main thread, or directly on one of the thread pool’s worker thread. This is controlled by flags.

type specifies the type (for example, QMetaType::QVector3D, QMetaType::QColor, or QMetaType::Float) of the animated value. When animating node properties this does not need to be provided separately, however it becomes important to supply this when there is only a callback.

Note

A mapping can be associated both with a node property and a callback. It is important however that type matches the type of the property in this case. Note also that for properties of type QVariant (for example, QParameter::value), the type is the type of the value stored in the QVariant.

Note

The callback pointer is expected to stay valid while any associated animators are running.

setChannelName(channelName)¶

Parameters:: channelName – str
