Attribute Struct Reference

This reference page is linked to from the following overview topics: Attributes, Node Events.



Detailed Description

This is an abstract base structure for all attributes.

Do not use it directly, use AttributeInstance instead.

Each node has a list of attributes with different types. The attributes are used like plain data members of the node class, but in case of attributes, mudbox will be able to get a list of all the attributes in a node, and for example it will be possible so simply display a dialog to the used where it is possible to check and alter the value of the variables.

Examples:

FileEventHandler/FileEventHandler.h, FixedFunctionMaterial/FixedFunctionMaterial.h, ImmediateModeRenderer/ImmediateModeRenderer.h, MeshDisplace/displacer.h, SampleViewportFilter/SampleViewportFilter.cpp, SampleViewportFilter/SampleViewportFilter.h, TextureSwapperViewportFilter/TextureSwapperViewportFilter.cpp, TextureSwapperViewportFilter/TextureSwapperViewportFilter.h, and ToonMaterial/ToonMaterial.h.

This is valid only for pointer attributes (See AttributePointer). Returns the type of the pointer.

virtual void SetPointerValue ( Node pValue,
bool  bLink = true 
) [virtual]

This is valid only for pointer attributes (See AttributePointer). Sets the value of the pointer. This function is used only if you dont know exactly the type of the attribute. Use AttributePointer::SetValue otherwise.

Reimplemented in AttributePointer< type >, and AttributePointer< NURBSCurve >.

This function sets the owner of the attribute.

The owner receives all events for this attribute

The owner is the receiver of all events from the attribute. This function removes any old owner & installs a new owner. If NULL or 0 is used as an argument then the old owner is removed and no owner exists for this attribute.

virtual AttributeWidget* CreateEditorWidget ( QWidget *  pParent,
int  iWidth 
) [virtual]

This function creates and returns the address of a QWidget object.

The object then can be used in the interface to give the user control over the attribute value. Mudbox calls this function for every attribute in a node when it displays a properties dialog box for it. You must override it if you implement a new kind of attribute and want a special interface.

Parameters:
iWidth Width of the control in pixels.
