Library

  • PFCMAIN.PBL
  • PFEMAIN.PBL

Object relationships

PFC visual user objects are designed to be used with windows that are descendants of w_master.

Instance variables

U_rb includes instance variables:

Instance variable Description Data type Access
ib_IsObsolete Boolean Protected

Events

U_rb includes a precoded event script:

GetFocus

GetFocus

Description

Updates the parent window so it can set MicroHelp.

Usage

This event calls the pfc_ControlGotFocus event in the parent.

Functions

U_rb includes precoded object functions:

  • of_GetParentWindow
  • of_MessageBox

of_GetParentWindow

Description

Returns a reference to the parent window.

Access

Public

Syntax

instancename.of_GetParentWindow ( window )
Argument Description
instancename Instance name of u_rb
window Window variable into which the function places a reference to the parent window (passed by reference)

Return value

Integer. Returns 1 if the function succeeds and -1 if there is no parent window. If no parent window is found, window returns NULL.

Usage

The u_rb GetFocus event calls this function.

Examples

This example is from the u_rb GetFocus event:

Window   lw_parent

IF gnv_app.of_GetMicrohelp() THEN
       of_GetParentWindow(lw_parent)
       IF IsValid(lw_parent) THEN
       lw_parent.Dynamic Event &
          pfc_ControlGotFocus(this)
       END IF
END IF

of_MessageBox

Description

Displays a MessageBox.

Access

Protected

Syntax 1

instancename.of_MessageBox ( id, title, message, icon, button, default )
Argument Description
instancename Instance name of u_rb
id String specifying an ID for the message
title String specifying the title of the RadioButton
message String specifying the message text
icon Icon enumerated data type indicating the icon you want to display on the left side of the message box. Values are:
• Information!
• StopSign!
• Exclamation!
• Question!
• None!
button Button enumerated data type indicating the set of CommandButtons you want to display at the bottom of the message box. The buttons are numbered in the order listed in the enumerated data type. Values are:
• OK!
• OKCancel!
• YesNo!
• YesNoCancel!
• RetryCancel!
• AbortRetryIgnore!
default Integer specifying the number of the button you want to be the default button

Syntax 2 For a message that contains values (PFC 2025 and later)

instancename.of_MessageBox ( id, title, message, values, icon, button, default )
Argument Description
instancename Instance name of u_rb
values String array. The values for the placeholders in message

The other arguments are the same as in Syntax 1.

Return value

Integer. Returns 1 if the function succeeds and -1 if an error occurs.

Usage

Override this function to control MessageBox behavior in RadioButtons.

PFC 2025 and later When the language service is enabled (see the n_cst_appmanager of_SetLanguage function), the message comes from the language file if it has an entry for id: the entry id replaces message, and the entry id.title replaces title. Without the service, or without an entry, message and title are used as they are.

Use Syntax 2 for a message that contains values: message is the English text with placeholders (%s, or %1 - %9 by position) and values holds the values. Syntax 2 calls Syntax 1 to display the message, so an override of Syntax 1 still sees every message.

Examples

This example calls the of_MessageBox function:

of_Messagebox(’rb_error’,’Save’, &
   as_error, StopSign!, Ok!, 1)
...
