Parameter.Show operator

Introduced

v4.0

Description

Controls whether the parameter is inspectable or not. Calling this method with false is identical to setting the siNotInspectable capability flag (see Parameter.SetCapabilityFlag). A parameter on a CustomProperty or an FXTree node that is non-inspectable will not be shown in the Property Page or in the Scene Explorer; however, it is still accessible to scripting (see ProjectItem.Parameters). By creating hidden parameters on a CustomProperty or custom Operator, a plug-in can save private state information inside a scene.

An alternative way to exclude a parameter from a Property Page is to not include it in the PPGLayout.

C# Syntax

Parameter.Show( Boolean in_bShow );

Scripting Syntax

oBoolean = Parameter.Show();

Return Value

Boolean

VBScript Example

'
' This example demonstrates how to create hidden parameters 
'
NewScene , false 
' -------------------------------------
'	Method 1: Using the Show method 
dim oPset1, oParam 
set oPset1 = Application.ActiveSceneRoot.AddProperty( "CustomProperty", false, "HiddenWithShow" ) 
set oParam = oPset1.AddParameter2( "Hidden", siDouble ) 
oParam.Show( false ) 
oPset1.AddParameter2 "NotHidden", siDouble  
InspectObj oPset1 , , , siLock
' -------------------------------------
'	Method 2: Create a Property Page layout excluding this parameter 
dim oPset2, oLayout 
set oPset2 = Application.ActiveSceneRoot.AddProperty( "CustomProperty", false, "HiddenWithLayout" ) 
oPset2.AddParameter2 "Hidden", siDouble  
oPset2.AddParameter2 "NotHidden", siDouble  
set oLayout = oPSet2.PPGLayout 
oLayout.Clear 
oLayout.AddItem "NotHidden" 
InspectObj oPset2 , , , siLock
' In either case you can still read and write the 
' the values from the Object Model 
Application.LogMessage "Old Value for " & oPset1.FullName & ": " & oPset1.Parameters("Hidden").Value
oPset1.Parameters("Hidden").Value = 5
Application.LogMessage "New Value for " & oPset1.FullName & ": " & oPset1.Parameters("Hidden").Value
Application.LogMessage "Old Value for " & oPset2.FullName & ": " & oPset2.Parameters("Hidden").Value
oPset2.Parameters("Hidden").Value = 25
Application.LogMessage "New Value for " & oPset2.FullName & ": " & oPset2.Parameters("Hidden").Value
' Output of above script:
'INFO : Old Value for HiddenWithShow: 0
'INFO : New Value for HiddenWithShow: 5
'INFO : Old Value for HiddenWithLayout: 0
'INFO : New Value for HiddenWithLayout: 25
