[Anonymous]

I have made a ToolBar.

ToolBar sould know the timming when Node has selected.

ToolBar sould know whether Node is Selected or not.
To Enable the Button that apply the Some modifier to the Node, ToolBar hava to know Node Selection.

Would you explain this?

I Found that!!

through RegisterNotification Method, I could that

1. Make the Method which be gave and Process the Message.

Function prototype is

void (*FunctionName)(void*)(NotifyInfo*);

2. Register The Function By RegisterNotification() Method with NOTIFY_SELECTIONSET_CHANGED message ID;

RegisterNotification(FunctionName, (void *)this, NOTIFY_SELECTIONSET_CHANGED);

3. then you can get the message and process it!!
