Description​

The FORM statement declares a new form and adds it to the current module. In addition, this statement is used to describe the form structure, as well as its static and partially interactive (except form design) views. At the beginning of the statement, name and captions are specified, followed by form options and the declaration containing an arbitrary number of blocks describing the structure of the form. They can be used in any order, provided that each block is declared after the blocks whose elements it uses. Each block can be used any number of times.

Parameters​

  • name

  • caption

    Form caption. String literal. If the caption is not defined, the form's name will be its caption.

  • IMAGE path

    The relative path to the file with the image that will be used as the form icon.

    • path

      Path to the file. String literal. The path is relative to the images directory.

  • AUTOREFRESH period

    Specifying the automatic form update period. If the option is not specified, the form will not be updated automatically. deprecated since version 5, use EVENTS ON SCHEDULE refresh()

Examples​

CLASS Document;

// declaring the Documents form
FORM documents 'Documents'
    // Adding one object of the Document class. The object will be available by this name 
    // in the DESIGN, SHOW, EXPORT, DIALOG, etc. operators.
    OBJECTS d = Document 


    // ... adding properties and filters to the form

    // marking that this form should be used when it is necessary to select a document, 
    // while the d object should be used as a return value
    LIST Document OBJECT d 
;

CLASS Item;

// declaring the Product form
FORM item 'Product'
    // adding an object of the Item class and marking that it should be displayed
    // in the panel (i.e., only one value is visible)
    OBJECTS i = Item PANEL 

    // ... adding properties and filters to the form

    // marking that this form should be used when it is necessary to add or edit a product
    EDIT Item OBJECT i 
;

// declaring a form with a list of Products
FORM items 'Products'
    OBJECTS i = Item

    // ... adding properties and filters to the form

    // adding buttons that will create and edit the product using the item form
    PROPERTIES(i) NEWSESSION NEW, EDIT 
;

CLASS Invoice;
CLASS InvoiceDetail;

// declaring the invoice print form
FORM printInvoice
    OBJECTS i = Invoice // adding an object of the invoice class for which printing will be executed

    // ... adding properties and filters to the form
;

// splitting the form definition into two statements (the second statement can be transferred to another module)
EXTEND FORM printInvoice
    // adding invoice lines, each of which will be used in the report as a detail
    OBJECTS d = InvoiceDetail 

    // ... adding properties and filters to the form
;
// declaring an action that will open the invoice print form
print (Invoice invoice)  { PRINT printInvoice OBJECTS i = invoice; }
