## XSIDialog

Object Hierarchy

### Introduced

v2.0

### Description

This object allows you to launch a simple modal dialog contained a drop down list of strings. It is particularly useful when asking the user to select from a dynamically generated list of items.
An alternative approach is to use a Combo control on a CustomProperty (see PPGLayout.AddEnumControl).

### Methods

Combo | ComboEx |  |

### Examples

#### 1. VBScript Example

    dim XSIDial, aItems
    set XSIDial = CreateObject("XSIDial.XSIDialog" )
    aItems = Array( "Item1", "Item2", "Item3" )
    indx = XSIDial.ComboEx( "Window Title", aItems, 2 )
    if ( indx = -1 ) then
            Application.LogMessage "User cancelled"
    else
            Application.LogMessage "User selected: " & aItems( indx )
    end if

#### 2. JScript Example

    /*
            Demonstrates how you can ask the user to pick an object
            based on a list of object names
    */
    NewScene(null, false);
    // Create 4 nulls, with one nested underneath another
    GetPrim("Null", "FirstNull");
    GetPrim("Null", "MiddleNull");
    var oLastNull = GetPrim("Null", "LastNull");
    oLastNull.AddPrimitive("Null", "HiddenNull");
    // Look for our nulls based on the naming convention
    var dummy;
    var oNulls = ActiveSceneRoot.FindChildren( "*Null", dummy, dummy, true );
    // Fill their names into a string
    var aNames = new Array();
    for ( i=0 ; i<oNulls.Count; i++ ) {
            aNames.push( oNulls.Item(i).FullName );
    }
    // Often it is convenient to sort objects
    XSIUtils.QuickSort( aNames )
    var oDial = new ActiveXObject( "XSIDial.XSIDialog" );
    // Ask the user to pick a null
    indx = oDial.Combo( "Pick a Null", aNames );
    if ( indx != -1 ) {
            InspectObj( aNames[indx] );
    }
