## 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"
