Notify Manager - New Attribute?

Erenford — Tue, 01 Aug 2023 11:54:12 GMT

Can you catch if a user creates a new attribute similar to catching new elements? Like if I create a Layer/Layer Combo, it will have an event I can handle.

Thanks,
Erenford

Hi Erenford,

implement an AttributeSetObserver to catch events of the AttributeManager:

#include "AttributeManager.hpp" 
 
class MyAttributeSetObserver : public ADB::AttributeSetObserver { 
public: 
	MyAttributeSetObserver (); 
	virtual ~MyAttributeSetObserver (); 
 
	virtual	void	AttributeCreated (ADB::IDAttribute attributeTypeId, ADB::GeneralAttributeConstRef attribute) override; 
	virtual	void	AttributeChanged (ADB::IDAttribute attributeTypeId, ADB::GeneralAttributeConstRef attribute, const FieldMask& changes) override; 
	virtual	void	AttributeDeleted (ADB::IDAttribute attributeTypeId, short index) override; 
 
	virtual void	ActiveAttributeChanged (ADB::IDAttribute attributeTypeId, const ADB::GeneralAttributeRef& attributeRef) override; 
 
	virtual void	AttributeTypeRestored (ADB::IDAttribute attributeTypeId) override; 
}; 
 
 
MyAttributeSetObserver::MyAttributeSetObserver() 
{ 
	ADB::AttributeSetConstRef attrSet = GetCurrentAttributeSet (); 
	attrSet(ODB::LogicalConst)->Attach (*this); 
} 
 
 
MyAttributeSetObserver::~MyAttributeSetObserver() 
{ 
	ADB::AttributeSetConstRef attrSet = GetCurrentAttributeSet (); 
	attrSet(ODB::LogicalConst)->Detach (*this); 
} 
 
// Implement observer methods!

Regards,
Tibor

This looks useful. Can I ask where the class AttributeSet is defined?

I'm assuming it's in AttributeSet.hpp but I can't find it in the SDK(18.3006)

Both the class is referenced and the header is included in headers in AttributeManager

Any info on where this AttributeSet class is defined?

This is not part of the public API; what do you need that for?

Best, Akos

I was hoping it might provide a notification when layer status has changed, such a hiding or showing. If done via main menu there's no notification.

Thanks!

And what would you like to do when the notification arrives?

Best, Akos

I'd like to update the current render session. Notifications work fine when making changes to scene elements, but switching off a layer via the menu bypasses this system.

Hi,

I have a very similar problem and I am curious if there is any update here (SDK - AC21) or is it still an "internal function"?
