Member Data Documentation

◆ m_initialUpdate

bool WMTemplate::SafeUpdateCallback::m_initialUpdate

Denotes whether the update callback is called the first time.

It is especially useful to set some initial value even if the property has not yet changed.

Definition at line 350 of file WMTemplate.h.

Referenced by operator()().

◆ m_module

WMTemplate* WMTemplate::SafeUpdateCallback::m_module

Pointer used to access members of the module to modify the node.

Please do not use shared_ptr here as this would prevent deletion of the module as the callback contains a reference to it. It is safe to use a simple pointer here as callback get deleted before the module.
