## FCurve.Locked

### Introduced

v3.0

### Description

Sets or returns the locked property of fcurve as a Boolean (true if locked). If the fcurve is set as locked it cannot be changed. If you try changing an fcurve that is Locked it raises an 'Access Denied' (E_ACCESSDENIED) error.

### C# Syntax

    // get accessor

    Boolean rtn = FCurve.Locked;

    // set accessor

    FCurve.Locked = Boolean;

### Examples

#### Python Example

    #

    # This Python example illustrates how to create an fcurve and set it as Locked

    #

    # We try to import the Softimage constants from win32com.client. This assumes that

    # the makepy.py utility has been used on the Softimage type library files (.tlb);

    # this automatically installs the Softimage constants into win32com.client.constants

    #

    from win32com.client import constants

    from win32com.shell import shell

    import pythoncom

    # Define constants

    try:

    	siInfo = constants.siInfo

    	siStandardFCurve = constants.siStandardFCurve

    except:

    	# typelib not found

    	siInfo = 8

    	siStandardFCurve = 20

    # Create new scene

    null = Application.NewScene("", 0)

    # Create a null

    null = Application.GetPrim("Null", "", "", "")

    # Get the posx parameter from the null

    posx = null.posx

    # Define some keys

    keys = [ 1.00, -5.00, 100.00, 5.00 ]

    # Create an fcurve on posx

    fc = posx.AddFCurve2( keys, siStandardFCurve )

    # Get the current Locked value

    ro = fc.Locked

    Application.LogMessage( 'fc.Locked before = ' + str(ro), siInfo )

    # Set the fc Locked

    fc.Locked = 1

    ro = fc.Locked

    Application.LogMessage( 'fc.Locked after = ' + str(ro), siInfo )

    # Try setting a key when the fcurve is Locked.

    fckey = fc.Keys(0)

    Application.LogMessage( 'fckey.value before = ' + str(fckey.Value), siInfo )

    try:

    	fckey.Value = 5.00

    	Application.LogMessage( 'fckey.value after = ' + str(fckey.Value), siInfo )

    except pythoncom.com_error, (hr, msg, exc, arg):

    		# catch the error and print out the error message

    		if exc and exc[2]: msg = exc[2]

    		Application.LogMessage( "fcurve key set value failed:" + msg)

    # Produces the following output:

    #INFO : "fc.Locked before = 0"

    #INFO : "fc.Locked after = 1"

    #INFO : "fckey.value before = -5.0"

    #INFO : "2009 - fcurve key set value failed:Access denied"
