## Detailed Description

An interactive form – sometimes referred to as an AcroForm – is a collection of fields for gathering information interactively from the user. A PDF document may contain any number of fields appearing on any combination of pages, all of which make up a single, global interactive form spanning the entire document. Arbitrary subsets of these fields can be imported or exported from the document.
Function FoxitPDFSDKPython2.PDFDoc.HasForm can be used to judge if a PDF document has interactive form.
A form object can be constructed form a specified PDF document. This class offers functions to retrieve form fields or form controls, import/export form data and other features. For example:

- To retrieve form fields, please use functions FoxitPDFSDKPython2.Form.GetFieldCount and FoxitPDFSDKPython2.Form.GetField .
- To retrieve form controls from a PDF page, please use functions FoxitPDFSDKPython2.Form.GetControlCount and FoxitPDFSDKPython2.Form.GetControl .
- To import form data from an XML file, please use function FoxitPDFSDKPython2.Form.ImportFromXML ; to export form data to an XML file, please use function FoxitPDFSDKPython2.Form.ExportToXML .
- To retrieve form filler object, please use function FoxitPDFSDKPython2.Form.GetFormFiller .

To import form data from a FDF/XFDF file or export such data to a FDF/XFDF file, please refer to functions FoxitPDFSDKPython2.PDFDoc.ImportFromFDF and FoxitPDFSDKPython2.PDFDoc.ExportToFDF .
To fill the form, please construct a form filler object by current form object or retrieve the filler object by function FoxitPDFSDKPython2.Form.GetFormFiller if such object has been constructed. (There should be only one form filler object for an interactive form).

## Constructor & Destructor Documentation

## ◆ Form()

def FoxitPDFSDKPython2.Form.Form | ( |  | other | ) |

Constructor, with another form object.

Parameters

  [in] | other | Another form object.

## Member Function Documentation

## ◆ AddControl()

def FoxitPDFSDKPython2.Form.AddControl | ( |  | page,
|  |  | field_name,
|  |  | field_type,
|  |  | rect
| ) |  |

Add a new form control to a specified form field. If the form field does not exist, this function will add a form field as well. (Not support signature field)

Application can use this function to add a new form control:

- If the specified form field exists, a new form control will be created and set to the field.
- If the specified form field does not exist, a new form field will be created according to parameter field_name and field_type and added to form, along with a newly created form control.

Whether a form field exists or not, it will be judged with input parameters field_name and field_type.
If user wants to add a new signature field, please use function FoxitPDFSDKPython2.PDFPage.AddSignature instead of current function.
The newly added form control has no appearance, so user should use setting methods in class Control or in related pdf field or widget annotation to set properties which will affect appearance. Some setting methods of class FoxitPDFSDKPython2.Control and Field may directly update appearance, but functionFoxitPDFSDKPython2.Annot.ResetAppearanceStream of related widget annotation is still recommended to be called to ensure the appearance will indeed be updated.
For push button, check box, radio button, if user calls function FoxitPDFSDKPython2.Annot.ResetAppearanceStream directly without setting any properties, the default appearance style will be used:

- push button: In related widget annotation, background color (in the MK dictionary) = 0xC0C0C0, highlighting mode = FoxitPDFSDKPython2.Annot.e_HighlightingPush .
- check box/radio button: In related widget annotation, border width = 1.0, border style = FoxitPDFSDKPython2.BorderInfo.e_Solid , background color (in the MK dictionary) = 0xFFFFFF, border color (in the MK dictionary) = 0xFFFFFF.

Parameters

  [in] | page | A valid PDF page, in which the new form control will be added. It should belong to the same PDF document as current form.
  [in] | field_name | Field name. It should not be an empty string.
  [in] | field_type | Field type. Please refer to values starting from FoxitPDFSDKPython2.Field.e_TypePushButton and this should be one of these values except FoxitPDFSDKPython2.Field.e_TypeSignature . If this is FoxitPDFSDKPython2.Field.e_TypeSignature , this function will throw exception FoxitPDFSDKPython2.e_ErrUnsupported .
  [in] | rect | Rectangle of the new form control which specifies the position in PDF page. It should be in [PDF coordinate system] ().

Returns
  The newly added form control object.
