ACCELERATORS

acctablename ACCELERATORS
BEGIN
event, idvalue, [type] [options]

END

The ACCELERATORS statement defines one or more accelerators for an application. An accelerator is a keystroke defined by the application to give the user a quick way to perform a task. The TranslateAccelerator function is used to translate accelerator messages from the application queue into WM_COMMAND or WM_SYSCOMMAND messages.

Parameters

acctablename

Specifies either a unique name or an integer value that identifies the resource.

event

Specifies the keystroke to be used as an accelerator. It can be any one of the following character types:

Type

Description

“char”	A single ASCII character enclosed in double quotation marks. The character can be preceded by a caret (^), meaning that the character is a control character.
ASCII character	An integer value representing an ASCII character. The type parameter must be ASCII.
Virtual-key character	An integer value representing a virtual key. The virtual key for alphanumeric keys can be specified by placing the uppercase letter or number in double quotation marks (for example, “9” or “C”). The type parameter must be VIRTKEY.

idvalue

Specifies an integer value that identifies the accelerator.

type

Required only when the event parameter is an ASCII character or a virtual-key character. The type parameter specifies either ASCII or VIRTKEY; the integer value of event is interpreted accordingly. When VIRTKEY is specified and event contains a string, event must be uppercase.

options

Specifies the options that define the accelerator. This parameter can be one or more of the following values:

Option

Description

NOINVERT	Specifies that no top-level menu item is highlighted when the accelerator is used. This is useful when defining accelerators for actions such as scrolling that do not correspond to a menu item. If NOINVERT is omitted, a top-level menu item will be highlighted (if possible) when the accelerator is used.
ALT	Causes the accelerator to be activated only if the ALT key is down.
SHIFT	Causes the accelerator to be activated only if the SHIFT key is down.
CONTROL	Defines the character as a control character (the accelerator is only activated if the CONTROL key is down). This has the same effect as using a caret (^) before the accelerator character in the event parameter.

The ALT, SHIFT, and CONTROL options apply only to virtual keys.

Examples

The following example demonstrates the usage of accelerator keys:

1 ACCELERATORS
BEGIN
  "^C",  IDDCLEAR         ; control C
  "K",   IDDCLEAR         ; shift K
  "k",   IDDELLIPSE, ALT  ; alt K
  98,    IDDRECT, ASCII   ; b
  66,    IDDSTAR, ASCII   ; B (shift b)
  "g",   IDDRECT          ; g
  "G",   IDDSTAR          ; G (shift G)
  VK_F1, IDDCLEAR, VIRTKEY                ; F1
  VK_F1, IDDSTAR, CONTROL, VIRTKEY        ; control F1
  VK_F1, IDDELLIPSE, SHIFT, VIRTKEY       ; shift F1
  VK_F1, IDDRECT, ALT, VIRTKEY            ; alt F1
  VK_F2, IDDCLEAR, ALT, SHIFT, VIRTKEY    ; alt shift F2
  VK_F2, IDDSTAR, CONTROL, SHIFT, VIRTKEY ; ctrl shift F2
  VK_F2, IDDRECT, ALT, CONTROL, VIRTKEY   ; alt control F2
