Example

// The Combo Box control "COMBO_Title" displays the titles:
// "Mister", "Madam" and "Miss".
// An integer representing a gender will be returned to the language.
ListAdd(COMBO_Title, "Mister" + gLink("1"))
// Only the string "1" is returned to the language.
// This string is not displayed in the Combo Box control.
// Allow retrieving the value defined by gLink.
gLinkActivate(COMBO_Title, True)

Syntax

<Result> = gLinkActivate(<Name of List Box or Combo Box> [, <Active>])

<Result>: Boolean

Corresponds to the former management mode:
True if the value defined by gLink was retrieved (default value),
False otherwise.

<Name of List Box or Combo Box>: Character string (with or without quotes)

Name of List Box or Combo Box control to use.

<Active>: Optional boolean

True if the value defined by gLink must be retrieved (default value),
False otherwise.

Remarks

Activation/Deactivation

If the retrieval of values defined by gLink is enabled on the COMBO_COMBO1 control (<Active> = True):
COMBO_COMBO1..Value returns the order number in the COMBO_COMBO1 control.
COMBO_COMBO1[COMBO_COMBO1] returns the value of gLink.
- If the COMBO_COMBO1 control is linked to an item:
  - FileToScreen selects the row whose value of gLink is the one of the linked item.
  - ScreenToFile assigns the value of gLink to the linked HFSQL item.
If the retrieval of values defined by gLink is disabled on the COMBO_COMBO1 control (<Active> = False):
COMBO_COMBO1..Value returns the order number in the COMBO_COMBO1 control.
COMBO_COMBO1[COMBO_COMBO1] returns the current displayed value.
- If the COMBO_COMBO1 control is linked to an item:
  - FileToScreen selects the row whose rank is equal to the linked item.
  - ScreenToFile assigns the linked HFSQL item with the number of the selected element, which means ListSelect(COMBO_COMBO1).

ListSeek function

If gLinkActivate()=True, ListSeek takes the values added by gLink into account.
If gLinkActivate()=False, ListSeek ignores the values added by gLink. The search is performed on the displayed value.

Auto-filled combo boxes

gLinkActivate is used to manage auto-filled Combo Box controls.
