Detailed Description

Base class for control creation commands.

MPxControlCommand is the base class for user defined UI control commands. This command gives all of the flags and options of the base control command in addition to any user defined flags or behaviours. When registering this command, use the MFnPlugin::registerControlCommand() method. All control commands have a corresponding MPxUIControl. It is important to note that a given MPxControlCommand is reponsible for only ONE MPxUIControl.

Member Function Documentation

MPxUIControl * makeControl ( )
pure virtual

This method is called when the UI control should be created.

You need to create a new MPxUIControl on call to this method (the base implementation is abstract, so that the compiler will force you to define an implementation of this method).

Returns
  • NULL - unable to create the UI control for this command.
  • pointer to control - ui control successfully created.
MStatus doEditFlags ( )
virtual

This method is called when the command is called in edit mode.

This method should be overridden by control commands to determine which edit flags are set in conjunction with the argument parser for this command. The argument parser for this command can be obtained by calling the parser method.

If the command is called with both the edit flag and the query flag, then the query flag will be ignored.

If the command returns MS::kUnknownParameter, the flag is processed by the parent class.

Returns
  • MS::kSuccess operation successful
  • MS::kUnknownParameter pass to the parent class
  • MS::kFailure operation failed
MStatus doQueryFlags ( )
virtual

This method is invoked during query mode, and the default method should be overridden in user-defined control commands to determine which query flags are set in conjunction with the argument parser for the command.

The argument parser for this command can be obtained by calling the parser method. If the command is called with both the edit flag and the query flag, then the query flag will be ignored.

If the command returns MS::kUnknownParameter, the flag is processed by the parent class.

Returns
  • MS::kSuccess operation successful
  • MS::kUnknownParameter pass to the parent class
  • MS::kFailure operation failed
MStatus appendSyntax ( )
virtual

This method should be overridden to append syntax to the control command.

The syntax object can be obtained by calling the syntax method. The following flags cannot be used as user-defined flags as they are reserved for edit and query: "-e", "-edit", "-q", "-query".

Returns
  • MS::kSuccess operation successful
  • MS::kFailure operation failed
bool skipFlagForCreate ( const MString &  longFlag)
virtual

Returns true if the passed long flag name should be skipped during the creation portion of the command.

Parameters
[in]longFlagThe string containing the long flag name.
Returns
true if the flag shoiuld be skipped during creation.
Status Codes:
  • MS::kSuccess Operation successful
MStatus setResult ( bool  result)

This method should be called when the result of the control command is a boolean.

Parameters
[in]resultthe boolean result
Returns
  • MS::kSuccess operation successful
  • MS::kFailure operation failed
MStatus setResult ( int  result)

This method should be called when the result of the control command is an integer.

Parameters
[in]resultthe integer result
Returns
  • MS::kSuccess operation successful
  • MS::kFailure operation failed
MStatus setResult ( double  result)

This method should be called when the result of the control command is a double.

Parameters
[in]resultthe double result
Returns
  • MS::kSuccess operation successful
  • MS::kFailure operation failed
MStatus setResult ( const MString &  result)

This method should be called when the result of the control command is a string.

Parameters
[in]resultthe string result
Returns
  • MS::kSuccess operation successful
  • MS::kFailure operation failed
MStatus setResult ( const MStringArray &  result)

This method should be called when the result of the control command is a string array.

Parameters
[in]resultthe string result
Returns
  • MS::kSuccess operation successful
  • MS::kFailure operation failed
MStatus setResult ( const MIntArray &  result)

This method should be called when the result of the control command is a integer array.

Parameters
[in]resultthe integer array result
Returns
  • MS::kSuccess operation successful
  • MS::kFailure operation failed
const char * className ( )
static

Returns the name of this class.

Returns
Name of this class.
MPxUIControl * control ( MStatus *  ReturnStatus = NULL)
protected

USE _control() IN SCRIPT.

Returns the control instance.

All UI commands require the name of the UI control as the last argument. This name is stored in a table that has the pointer to the control. When the command is executed, the pointer is retrieved. You should only call this method in the doEditFlags & doQueryFlags. All other cases are invalid.

Parameters
[out]ReturnStatusreturn status
Status Codes:
  • MS::kSuccess operation successful
  • MS::kFailure operation failed
MSyntax syntax ( MStatus *  ReturnStatus = NULL) const
protected

USE _syntax() IN SCRIPT.

This method returns the syntax object of this control command.

The syntax object can be appended to in an overridden version of the appendSyntax method.

Parameters
[out]ReturnStatusreturn status
Returns
  • the syntax object
Status Codes:
  • MS::kSuccess operation successful
  • MS::kFailure operation failed
MArgParser parser ( MStatus *  ReturnStatus = NULL) const
protected

USE _parser() IN SCRIPT.

This method returns the argument parser of this control command.

The argument parser can be used in the overridden versions of doEditFlags and doQueryFlags to determine which flags are set.

Parameters
[out]ReturnStatusreturn status
Returns
The argument parser
Status Codes:
  • MS::kSuccess operation successful
  • MS::kFailure operation failed
