Setting Parameter Visibility

By default, all plug-in parameter users interface controls are enabled and visible. This behavior may be overridden using SetParameterVisibility() and EnableParameter(). Using GetCustomObjectInfo() or GetPluginInfo() with these procedures is relatively straightforward. First, use GetCustomObjectInfo() to obtain information about the object. Once this information has been retrieved, the plug-in parameter’s user interface attributes can be specified. In each case, the parameter argument is the universal name of the plug-in’s parameter. For example:

 

BEGIN

...

resultsStatus := GetCustomObjectInfo(objName,objHd,recHd,wallHD);

IF resultStatus THEN BEGIN

EnableParamter(objHD, ‘Space Width’. FALSE);

{Disables the control for the Space Width parameter}

SetParameterVisibility(objHd, ‘Space Depth’. FALSE);

{Hides the control from the Space Width parameter}

...

END;

END;

Like the plug-in object example above, plug-in menus and tools that use parameters can use SetParameterVisibility() and EnableParameter().

 

BEGIN

...

...

IF GetPluginInfo(cmdName,pRecHd) THEN

cmdHd:= GetObject(cmdName);

EnableParameter(objHd, ‘Offset’. FALSE);

SetParameterVisibility(objHd, ‘Lines’. FALSE);

END;

...

...

END;
