Managing drop downs in the default OIP

[Sam Jones]

I have an event aware point object that that has a drop down list of vendors.  When a user changes the vendor name there are 2 other drop down menus that change the contents of their list based on the value of the newly selected drop down.  When the user changes a vendor value in an already placed instance of the PIO, all goes according to plan.  The vsoStateGetParamChng() function yields points to the vendor as having changed; I query the value, and I then change the lists in the other drop down.

 

Is there any way to get this functionality in the default OIP dialog that comes up when selected in the mode bar.  Currently, changing the vendor value in the default OIP does not tell any part of the code that the vendor parameter has changed, there seems to be no way to then change the lists in the drop downs of the default OIP.

 

Is there a way to do that?

I'm more curious about getting different drop-down values conditionally based upon a different drop-down's value.  Looks like something else to have fun learning!

If we are not talking about the default OIP, this is easily done.  In the Reset Event, you need the following statements

IF vsoStateGetParamChng(PIOHan,  OutWidgID, ParamIndex, OldValue ) THEN
    BEGIN

         {Check if the changed parameter is equal to the one you want to base the change of another parameter on}

         {Get the value of the changed parameter}

         IF theValue is a signal to change another drop down THEN

             BEGIN

                  booResult := vsoPrmName2WidgetID('',NameOfParameterToChange, OutWidgID);

                  vsoWidgetPopupClear(OutWidgID);

                  FOR index := 1 TO NumberOfChoices DO

                       BEGIN

                               vsoWidgetPopupAdd(OutWidgID, NewValue[index], NewValue[index]);

                       END

             END; {IF theValue is a signal to change}

     END; {IF vsoStateGetParamChng}

Cool!  I'll play around with this!
