hb_SetKeySave()

Posted on by vivaclipper

HB_SETKEYSAVE()

Returns a copy of internal set-key list, optionally overwriting

Syntax

      HB_SETKEYSAVE( [ <OldKeys> ] )

Arguments

<OldKeys> is an optional set-key list from a previous call to HB_SetKeySave(), or NIL to clear current set-key list

Returns

Current set-key list

Description

HB_SetKeySave() is designed to act like the set() function which returns the current state of an environment setting, and optionally assigning a new value. In this case, the “environment setting” is the internal set-key list, and the optional new value is either a value returned from a previous call to SetKeySave() – to restore that list, or the value of NIL to clear the current list.

Examples

      LOCAL aKeys := HB_SetKeySave( NIL )  // removes all current set=keys
      ... // some other processing
      HB_SetKeySave( aKeys )

Tests

      None definable

hb_SetKeyGet()

HB_SetKeyGet()

Determine a set-key code block and condition-block

Syntax

      HB_SETKEYGET( <nKey> [, <bConditionByRef> ] )

Arguments

<anKey> is an numeric key value

<bConditionByRef> is an optional return-parameter

Returns

Current assigned action-block

Description

The HB_SetKeyGet() function returns the current code-block assigned to a key, and optionally assigns the condition-block to the return-parameter

Examples

      LOCAL bOldF10, bOldF10Cond
      bOldF10 := HB_SetKeyGet( K_F10, @bOldF10Cond )
      ... // some other processing
      SetKey( K_F10, bOldF10, bOldF10Cond )

Tests

      See test code above
