TGet / TMGet

Text input controls with PICTURE formatting, validation, and multi-line editing

TGet Overview

Fuente: source/classes/tget.prg  |  Parent: TControl

TGet is the FiveWin equivalent of the classic Clipper GET command -- a single-line text input control that supports PICTURE masks, validation blocks, and data binding via bSetGet. It is the workhorse of data-entry forms.

TMGet Overview

Fuente: source/classes/mget.prg  |  Parent: TControl

TMGet (also known as a memo GET) provides multi-line text editing. It is used for free-form text fields such as notes, comments, and descriptions. It wraps the Windows EDIT control with the ES_MULTILINE style.

Code Examples

Example 1: Data Entry Form with Various GET Types

#include "FiveWin.ch"

FUNCTION CustomerForm()
   LOCAL oDlg, oFont
   LOCAL cName   := Space( 30 )
   LOCAL cPhone  := Space( 14 )
   LOCAL nAge    := 0
   LOCAL dBirth  := CToD( "" )
   LOCAL cPass   := Space( 12 )
   LOCAL nSalary := 0
   LOCAL cNotes  := Space( 500 )

   DEFINE FONT oFont NAME "Segoe UI" SIZE 0, -14
   DEFINE DIALOG oDlg TITLE "Customer Entry" SIZE 480, 520 FONT oFont

   // Text input with uppercase mask
   @ 1.0, 1 SAY "Name:" OF oDlg
   @ 1.0, 6 GET cName OF oDlg SIZE 200, 22 ;
      PICTURE "@!" ;
      VALID ( !Empty( cName ) ) ;
      CUETEXT "Enter full name"

   // Phone with template mask
   @ 2.5, 1 SAY "Phone:" OF oDlg
   @ 2.5, 6 GET cPhone OF oDlg SIZE 140, 22 ;
      PICTURE "(999)999-9999"

   // Numeric with spinner
   @ 4.0, 1 SAY "Age:" OF oDlg
   @ 4.0, 6 GET nAge OF oDlg SIZE 80, 22 ;
      PICTURE "999" ;
      SPINNER MIN 0 MAX 120

   // Date field
   @ 5.5, 1 SAY "Birth Date:" OF oDlg
   @ 5.5, 6 GET dBirth OF oDlg SIZE 100, 22 ;
      PICTURE "99/99/9999"

   // Password field
   @ 7.0, 1 SAY "Password:" OF oDlg
   @ 7.0, 6 GET cPass OF oDlg SIZE 160, 22 ;
      PASSWORD

   // Numeric with European formatting
   @ 8.5, 1 SAY "Salary:" OF oDlg
   @ 8.5, 6 GET nSalary OF oDlg SIZE 140, 22 ;
      PICTURE "@E 9,999,999.99" ;
      RIGHT

   // Multi-line memo
   @ 10.0, 1 SAY "Notes:" OF oDlg
   @ 10.5, 1 GET cNotes MEMO OF oDlg SIZE 400, 100

   // Buttons
   @ 17, 6  BUTTON "&Save"   OF oDlg SIZE 80, 25 ACTION oDlg:End() DEFAULT
   @ 17, 16 BUTTON "&Cancel" OF oDlg SIZE 80, 25 ACTION oDlg:End() CANCEL

   ACTIVATE DIALOG oDlg CENTERED

   RELEASE FONT oFont
RETURN NIL

Example 2: Validated GET with Dynamic WHEN

#include "FiveWin.ch"

FUNCTION ValidatedForm()
   LOCAL oDlg
   LOCAL cCode    := Space( 5 )
   LOCAL cDesc    := Space( 40 )
   LOCAL nQty     := 0
   LOCAL nPrice   := 0
   LOCAL lApprove := .F.

   DEFINE DIALOG oDlg TITLE "Order Entry" SIZE 400, 300

   @ 1, 1 SAY "Code:" OF oDlg
   @ 1, 5 GET cCode OF oDlg SIZE 80, 22 ;
      PICTURE "@!" ;
      VALID ( ValidateCode( cCode, @cDesc ) )  // look up code, fill description

   @ 2.5, 1 SAY "Description:" OF oDlg
   @ 2.5, 5 GET cDesc OF oDlg SIZE 200, 22 READONLY

   @ 4.0, 1 SAY "Quantity:" OF oDlg
   @ 4.0, 5 GET nQty OF oDlg SIZE 80, 22 ;
      PICTURE "9999" ;
      SPINNER MIN 1 MAX 9999 ;
      VALID ( nQty > 0 )

   @ 5.5, 1 SAY "Price:" OF oDlg
   @ 5.5, 5 GET nPrice OF oDlg SIZE 100, 22 ;
      PICTURE "@E 99,999.99" ;
      WHEN ( !Empty( cCode ) )          // only enabled after valid code

   @ 7.5, 5 BUTTON "&OK" OF oDlg SIZE 80, 25 ;
      ACTION ( lApprove := .T., oDlg:End() ) DEFAULT

   @ 7.5, 14 BUTTON "&Cancel" OF oDlg SIZE 80, 25 ;
      ACTION oDlg:End() CANCEL

   ACTIVATE DIALOG oDlg CENTERED

   IF lApprove
      // process the order...
   ENDIF
RETURN NIL

STATIC FUNCTION ValidateCode( cCode, cDesc )
   IF Empty( cCode )
      MsgStop( "Code is required." )
      RETURN .F.
   ENDIF
   // Look up in database
   cDesc := GetDescForCode( AllTrim( cCode ) )
   IF Empty( cDesc )
      MsgStop( "Code not found." )
      RETURN .F.
   ENDIF
RETURN .T.

Tips and Best Practices

• The bSetGet block is created automatically by the GET var command. To bind to a field: GET FieldWBlock( "NAME", Select() ).
• Use CUETEXT (placeholder) to give the user a hint about expected input format.
• The bValid block can display a message and return .F. to prevent the user from leaving the field.
• For numeric GETs, always provide a PICTURE to control decimal places and thousands separators.
• The SPINNER clause adds increment/decrement arrows; combine with MIN/MAX to constrain the range.
• TMGet supports HSCROLL to add a horizontal scroll bar, and NO WORDWRAP to disable wrapping.
• When using GETs in a dialog, FiveWin handles Tab-order automatically based on creation order.
