/**
|
|
This header contains two macros that can be used to simplify the creation
|
|
of plug-in commands.
|
|
|
|
DeclareSimpleCommand( className, vendorName, version )
|
|
To use this macro, you provide it with the name of the class that
|
|
should be derived from MPxCommand, the name of your organisation, and
|
|
the version number of the plug-in. The macro expands to all the
|
|
code necessary to create a command except for the command's "doIt"
|
|
method. You need to provide a function with the prototype
|
|
|
|
MStatus className::doIt( const MArgList& )
|
|
|
|
You can also call methods inherited from MPxCommand such as
|
|
"setResult", "displayWarning", and "displayError".
|
|
|
|
DeclareSingle( functionPtr )
|
|
To use this macro you must write a function with the prototype:
|
|
MStatus functionPtr ( const MArgList& )
|
|
|
|
The macro expands to all the code necessary to create a basic non-undoable
|
|
command that calls "functionPtr" from it's doIt method. One limitation
|
|
of using this macro is that since "functionPtr" is not a member of the
|
|
class derived from MPxCommand, it cannot call methods (like setResult)
|
|
that are inherited from that class.
