SFDocuments.FormControl service

The FormControl service provides access to the controls that belong to a form, a subform or a table control of a FormDocument. Each instance of the FormControl service refers to a single control in the form. This service allows users to:

To use the FormControl service in a particular form, subform or table control, all controls must have unique names.

warning

Radio buttons that share the same group name must also have unique control names.


The main purpose of the FormControl service is setting and getting the properties and values displayed by the controls in a form.

All controls have a Value property. However, its contents will vary according to the control type. For more information, read The Value Property below.

It is also possible to format the controls via the XControlModel and XControlView properties.

tip

The SFDocuments.FormControl service is closely related to the SFDocuments.Form service.


Invocación del servicio

Antes de utilizar el servicio FormControl, es necesario cargar o importar la biblioteca ScriptForge:

note

• Para cargar la biblioteca ScriptForge que necesitan las macros de Basic se debe usar la siguiente declaración:
GlobalScope.BasicLibraries.loadLibrary("ScriptForge")

• Los scripts de Python necesitan importar el módulo scriptforge:
from scriptforge import CreateScriptService


The FormControl service is invoked from an existing Form service instance through its Controls method.


      Dim oDoc as Object, myForm As Object, myControl As Object
      Set oDoc = CreateScriptService("SFDocuments.Document", ThisDataBaseDocument)
      Set myForm = oDoc.Forms("formDocumentName", "formName") ' SFDocuments.Form
      Set myControl = myForm.Controls("myTextBox") ' SFDocuments.FormControl
      myControl.Value = "Current time = " & Now()
   
En Python

      

from scriptforge import CreateScriptService

from time import localtime, strftime bas = CreateScriptService('ScriptForge.Basic')

doc = CreateScriptService('SFDocuments.Document', bas.ThisDatabaseDocument)

form = doc.Forms('formDocumentName', 'formName') # SFDocuments.Form

control = form.Controls('myTextBox') # SFDocuments.FormControl

control.Value = 'Current Time = ' + strftime("%a, %d %b %Y %H:%M:%S", localtime())
tip

To learn more about how to open a FormDocument and get access to its forms, refer to the SFDocuments.Form service help page.


Alternatively a FormControl instance can be retrieved via the SFDocuments.FormEvent service, which returns the SFDocuments.FormControl class instance that triggered the event.


      Sub OnEvent(ByRef poEvent As Object)
          Dim oControl As Object
          Set oControl = CreateScriptService("SFDocuments.FormEvent", poEvent)
          ' oControl now represents the instance of the FormControl class that triggered the current event
          ' ...
      End Sub
   
En Python

      def onEvent(event: uno):
          control = CreateScriptService('SfDocuments.FormEvent', event)
   

Note that in previous examples, the prefix "SFDocuments." may be omitted.

note

The FormEvent service is used exclusively to create instances of the SFDocuments.Form and SFDocuments.FormControl services when a form or control event takes place.

Lista de métodos en el servicio FormControl

Controls

SetFocus


Controls

This method is applicable only to controls of the TableControl type. The returned value depends on the arguments provided.

If the optional argument controlname is absent, then a zero-based Array containing the names of all controls is returned.

On the other hand, if a controlname is provided, the method returns a FormControl class instance corresponding to the specified control.

Sintaxis:

svc.Controls(): str[0..*]

svc.Controls(controlname: str): svc

Parámetros:

controlname: A valid control name as a case-sensitive string. If absent, the list of control names is returned as a zero-based array.

Ejemplo:


      Dim myGrid As Object, myList As Variant, myControl As Object
      Set myGrid = myForm.Controls("myTableControl") ' SFDocuments.FormControl
      ' Returns an Array with the names of all controls in "myTableControl"
      myList = myGrid.Controls()
      

' Returns a FormControl class instance corresponding to "myCheckBox"

Set myControl = myGrid.Controls("myCheckBox")

Con Python:


      grid = form.Controls('myTableControl')  # SFDocuments.FormControl
      control_names = form.Controls()
      control = grid.Controls('myCheckBox')  # SFDocuments.FormControl
   

SetFocus

Sets the focus on the control. Returns True if focusing was successful.

This method is often called from a form or control event.

Sintaxis:

svc.SetFocus(): bool

Ejemplo:


      Dim oDoc As Object, oForm As Object, oControl As Object
      Set oDoc = CreateScriptService("SFDocuments.Document", ThisComponent)
      Set oForm = oDoc.Forms(0)
      Set oControl = oForm.Controls("thisControl") ' SFDocuments.FormControl
      oControl.SetFocus()
   
En Python

     bas = CreateScriptService('ScriptForge.Basic')
     doc = CreateScriptService('SFDocuments.Document', bas.ThisComponent)
     form = doc.Forms(0)
     control = form.Controls('thisControl')  # SFDocuments.FormControl
     control.SetFocus()
   

Ejemplos adicionales

Below are two examples that illustrate the use of the FormControl service.

The first example reads the current value in a ComboBox containing city names and writes it to a FixedTest control in a Form:


     Dim oDoc as Object, myForm as Object, myControl as Object
     Set oDoc = CreateScriptService("SFDocuments.Document", ThisDataBaseDocument)
     myForm = oDoc.Forms("formDocumentName", "formName")
     Dim lbCity : lbCity = myForm.Controls("labelCity")
     Dim cbCity : cbCity = myForm.Controls("comboboxCity")
     lbCity.Caption = "Selected City: " & cbCity.Value
   
En Python

     bas = CreateScriptService('ScriptForge.Basic')  # Métodos semejantes a BASIC
     doc = CreateScriptService('SFDocuments.Document', bas.ThisDatabaseDocument)
     form = doc.Forms('formDocumentName', 'formName')
     lbl_city = form.Controls('labelCity')
     combo_city = form.Controls('comboboxCity')
     lbl_city.Caption = "Ciudad seleccionada: " + combo_city.Value
   

The following code snippet can be used to process RadioButton controls that share the same group name. In this example, suppose there are three radio buttons with names optA, optB and optC and we wish to display the caption of the selected control.


     Dim oDoc as Object, myForm as Object
     Set oDoc = CreateScriptService("SFDocuments.Document", ThisDataBaseDocument)
     myForm = oDoc.Forms("formDocumentName", "formName")
     Dim optNames As Object : optNames = Array("optA", "optB", "optC")
     Dim optControl as Object, opt as Variant
     For Each opt In optNames
         optControl = myForm.Controls(opt)
         If optControl.Value = True Then
             MsgBox "Opción seleccionada: " & optControl.Caption
             Exit For
         End If
     Next opt
   
En Python

     bas = CreateScriptService('ScriptForge.Basic')  # Métodos semejantes a BASIC
     doc = CreateScriptService('SFDocuments.Document', bas.ThisDatabaseDocument)
     form = doc.Forms('formDocumentName', 'formName')
     radio_buttons = ['optA', 'optB', 'optC']
     for name in radio_buttons:
        control = form.controls(name)
        if control.Value == True:
           bas.MsgBox('Opción seleccionada: ' + control.Caption)
           break
