CMFCAcceleratorKey Class
The new home for Visual Studio documentation is Visual Studio 2017 Documentation on docs.microsoft.com.
The latest version of this topic can be found at CMFCAcceleratorKey Class.
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`.
