== Arguments ==
:'''index'''

:'''action'''

||'''Symbolic Constant''' || '''Control Action''' || 
||CA_PREVIEW || Updates the proxy preview window. || 
||CA_APPLY || Applies the filter to the original source image and exits the plug-in. || 
||CA_CANCEL || Exits the plug-in filter without modifying the original source image. || 
||CA_EDIT || Enters or exits source code editing mode (ignored in standalone filters). || 
||CA_ABOUT || Displays the ABOUT dialog box. || 
||CA_RESET || Resets all controls to their initial values. || 
||CA_NONE || Performs no action. || 
||CA_SIZE || Triggers a FME_SIZE (resize) event. That way you don't need to duplicate your sizing code anywhere else. ||

setCtlAction( 5, CA_APPLY );
