' This example demonstrates how to show/hide a widget in document.

' Create Bytescout.PDF.Document object
Set pdfDocument = CreateObject("Bytescout.PDF.Document")

pdfDocument.RegistrationKey = "demo"

' If you wish to load an existing document uncomment the line below And comment the Add page section instead
' pdfDocument.Load("existing_document.pdf")

Set comHelpers = pdfDocument.ComHelpers

' Add page
Set page1 = comHelpers.CreatePage(comHelpers.PAPERFORMAT_A4)
pdfDocument.Pages.Add(page1)

' Create widget that will be shown/hidden
Set editBox1 = comHelpers.CreateEditBox(20, 20, 100, 25, "editBox1")
editBox1.Text = "editBox1"
page1.Annotations.Add(editBox1)

' Create button that will show the widget
Set buttonShow = comHelpers.CreatePushButton(20, 80, 50, 25, "buttonShow")
buttonShow.Caption = "Show"
page1.Annotations.Add(buttonShow)
' Add Show action
Set showAction = comHelpers.CreateHideAction(False)
showAction.Fields.Add(editBox1)
buttonShow.OnActivated = showAction

' Create button that will hide the widget
Set buttonHide = comHelpers.CreatePushButton(100, 80, 50, 25, "buttonHide")

' Save document to file
