A helper class that implements virtual key mapping and formatting.

Syntax

class CMFCAcceleratorKey : public CObject

Members

Public Constructors

Name	Description
CMFCAcceleratorKey::CMFCAcceleratorKey	Constructs a `CMFCAcceleratorKey` object.

Public Methods

Name	Description
CMFCAcceleratorKey::Format	Translates the ACCEL structure to its visual representation.
CMFCAcceleratorKey::SetAccelerator	Sets the shortcut key for the `CMFCAcceleratorKey` object.

Remarks

Accelerator keys are also known as shortcut keys. If you want to display keyboard shortcuts that a user enters, the CMFCAcceleratorKeyAssignCtrl Class maps keyboard shortcuts, such as Alt+Shift+S, to a custom text format, such as "Alt + Shift + S". Each CMFCAcceleratorKey object maps a single shortcut key to a text format.

For more information about how to use shortcut keys and accelerator tables, see CKeyboardManager Class.

Example

The following example demonstrates how to construct a CMFCAcceleratorKey object and how to use its Format method.

  CString strKey;
    ACCEL accel;
    accel.fVirt = FVIRTKEY | FCONTROL;
    accel.key = VK_DOWN;

    CMFCAcceleratorKey helper(&accel);
    helper.Format(strKey);

CMFCAcceleratorKey::CMFCAcceleratorKey

Constructs a CMFCAcceleratorKey object.

CMFCAcceleratorKey();  
CMFCAcceleratorKey(LPACCEL lpAccel);
```  
  
### Parameters  
 [in] `lpAccel`  
 A pointer to a shortcut key.  
  
### Remarks  
 If you do not provide a shortcut key when you create a `CMFCAccleratorKey`, use the [CMFCAcceleratorKey::SetAccelerator](#cmfcacceleratorkey__setaccelerator) method to associate a shortcut key with your `CMFCAcceleratorKey` object.  
  
##  <a name="cmfcacceleratorkey__format"></a>  CMFCAcceleratorKey::Format  
 Translates the ACCEL structure to its associated string value.

void Format(CString& str) const;

  
### Parameters  
 [out] `str`  
 A reference to a `CString` object where the method writes the translated shortcut key.  
  
### Remarks  
 This method retrieves the string format of the associated shortcut key. You can set the string format of a [CMFCAcceleratorKey](../Topic/CMFCAcceleratorKey%20Class.md) object using either the constructor or the method [CMFCAcceleratorKey::SetAccelerator](#cmfcacceleratorkey__setaccelerator).  
  
##  <a name="cmfcacceleratorkey__setaccelerator"></a>  CMFCAcceleratorKey::SetAccelerator  
 Sets the shortcut key for the [CMFCAcceleratorKey](../Topic/CMFCAcceleratorKey%20Class.md) object.

void SetAccelerator(LPACCEL lpAccel);

  
### Parameters  
 [in] `lpAccel`  
 A pointer to a shortcut key.  
  
### Remarks  
 Use this method to set the shortcut key for a `CMFCAcceleratorKey` if you did not provide a shortcut key when you created the `CMFCAcceleratorKey`.
