# 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:

- Get and set the properties of the control represented by the FormControl instance.

- Access the current value displayed by the control.

- Set the focus on the desired control.

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

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.

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

## Service invocation

Before using the FormControl service the ScriptForge library needs to be loaded or imported:

• Basic macros require to load ScriptForge library using the following statement:
GlobalScope.BasicLibraries.loadLibrary("ScriptForge")
• Python scripts require an import from scriptforge module:
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()

##### In 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())

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

##### In Python

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

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

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.

List of Methods in the FormControl Service
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.

### Sintaksė:

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

svc.Controls(controlname: str): svc

### Parametrai:

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

### Pavyzdys:

          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")

Using 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.

### Sintaksė:

svc.SetFocus(): bool

### Pavyzdys:

          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()

##### In Python

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

## Additional examples

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

##### In Python

         bas = CreateScriptService('ScriptForge.Basic')  # Basic-like methods
         doc = CreateScriptService('SFDocuments.Document', bas.ThisDatabaseDocument)
         form = doc.Forms('formDocumentName', 'formName')
         lbl_city = form.Controls('labelCity')
         combo_city = form.Controls('comboboxCity')
         lbl_city.Caption = "Selected city: " + 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 "Selected option: " & optControl.Caption
                 Exit For
             End If
         Next opt

##### In Python

         bas = CreateScriptService('ScriptForge.Basic')  # Basic-like methods
         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('Selected option: ' + control.Caption)
               break
