%HI_GetMasterVisible, %HI_SetMasterVisible functions

Functions
The %HI_SetMasterVisible function hides the object (overloads %HI_SetVisible) / cancels the overloading and enables to control the displaying of graphic object by %HI_SetVisible (control function).

The %HI_GetMasterVisible function gets the current status of overloading of object that is set by %HI_SetMasterVisible.
Declaration
%HI_SetMasterVisible(
   INT in refId,
   BOOL in bVisible
 )
 
 
 BOOL %HI_GetMasterVisible(
   INT in refId
 )

Parameters
refId Reference to graphic object (reference variable).
bEnable @TRUE - shows the graphic object, which is controlled by %HI_SetVisible
@FALSE - hides the graphic object

Description
The %HI_SetMasterVisible function hides the graphic objects or tab of the object Windows control - Tabs - the parameter refId defines the name of the reference variable for particular graphic object or the tab. When bEnable parameter is @FALSE, it overloads the %HI_SetVisible function (disables its functionality).

The %HI_GetMasterVisible gets the current status of object overloading that is set by %HI_SetMasterVisible. The return value @TRUE does not mean that the object is visible, but the object is controlled by the %HI_SetVisible function. @FALSE zmeans the controlling of object by %HI_SetVisible function is blocked and the object is visible.

The behavior of Master functions is described in the chapter Master function.
Example
 ENTRY OnLogOn(IN TEXT _userName, IN BOOL _bLogOn)
   IF _bLogOn THEN
 
    ;when a user is logged on, the object is visible
    %HI_SetMasterVisible(_Text,@TRUE)
  ELSE
 
    ;when a user is logged off, the object is hide
    %HI_SetMasterVisible(_Text,@FALSE)
  ENDIF
 END OnLogOn
