CMFCAcceleratorKeyAssignCtrl Class

The latest version of this topic can be found at CMFCAcceleratorKeyAssignCtrl Class.

The CMFCAcceleratorKeyAssignCtrl class extends the CEdit Class to support extra system buttons such as ALT, CONTROL, and SHIFT.

Syntax

class CMFCAcceleratorKeyAssignCtrl : public CEdit  

Members

Public Constructors

Name Description
CMFCAcceleratorKeyAssignCtrl::CMFCAcceleratorKeyAssignCtrl Constructs a CMFCAcceleratorKeyAssignCtrl object.

Public Methods

Name Description
CMFCAcceleratorKeyAssignCtrl::GetAccel Retrieves the ACCEL structure for a shortcut key pressed in the CMFCAcceleratorKeyAssignCtrl object.
CMFCAcceleratorKeyAssignCtrl::IsFocused
CMFCAcceleratorKeyAssignCtrl::IsKeyDefined Determines whether a shortcut key has been defined.
CMFCAcceleratorKeyAssignCtrl::PreTranslateMessage Used by class CWinApp to translate window messages before they are dispatched to the TranslateMessage and DispatchMessage Windows functions. (Overrides CWnd::PreTranslateMessage.)
CMFCAcceleratorKeyAssignCtrl::ResetKey Resets the shortcut key.

Remarks

This class extends the functionality of the CEdit class by supporting shortcut keys, also known as accelerator keys. The CMFCAcceleratorKeyAssignCtrl class functions as a CEdit Class and it can also recognize system buttons.

This class maps physical shortcut key combinations to string values. For example, assume the key combination ALT + B is mapped to the string "Alt + B". When the user presses this key combination in a CMFCAcceleratorKeyAssignCtrl object, "Alt + B" is displayed to the user. For more information about the mapping between shortcut keys and a string format, see CMFCAcceleratorKey Class.

Example

The following example demonstrates how to construct a CMFCAcceleratorKeyAssignCtrl object and use its ResetKey method to reset the shortcut key.

    CMFCAcceleratorKeyAssignCtrl* accelCtrl = new CMFCAcceleratorKeyAssignCtrl();
    accelCtrl->ResetKey();

CMFCAcceleratorKeyAssignCtrl::CMFCAcceleratorKeyAssignCtrl

Constructs a CMFCAcceleratorKeyAssignCtrl object.

CMFCAcceleratorKeyAssignCtrl();

CMFCAcceleratorKeyAssignCtrl::GetAccel

Retrieves the ACCEL structure for a shortcut key pressed in the CMFCAcceleratorKeyAssignCtrl object.

ACCEL const* GetAccel() const;  

Return Value

An ACCEL structure that describes the shortcut key.

Remarks

Use this function to retrieve the ACCEL structure for a shortcut key that the user entered into your CMFCAcceleratorKeyAssignCtrl object.

CMFCAcceleratorKeyAssignCtrl::IsFocused

This topic is included for completeness. For more detail see the source code located in the VC\atlmfc\src\mfc folder of your Visual Studio installation.

BOOL IsFocused() const;  

Return Value

Remarks

CMFCAcceleratorKeyAssignCtrl::IsKeyDefined

Determines whether a shortcut key has been defined in the CMFCAcceleratorKeyAssignCtrl object.

BOOL IsKeyDefined() const;  

Return Value

Nonzero if the user has already pressed a valid combination of keys that define a shortcut key; otherwise 0.

Remarks

Use this function to determine whether the user entered a valid shortcut key in your CMFCAcceleratorKeyAssignCtrl object. If a shortcut key exists, you can use CMFCAcceleratorKeyAssignCtrl::GetAccel method to obtain the ACCEL structure associated with this shortcut key.

CMFCAcceleratorKeyAssignCtrl::PreTranslateMessage

This topic is included for completeness. For more detail see the source code located in the VC\atlmfc\src\mfc folder of your Visual Studio installation.

virtual BOOL PreTranslateMessage(MSG* pMsg);

Parameters

[in] pMsg

Return Value

Remarks

CMFCAcceleratorKeyAssignCtrl::ResetKey

Resets the shortcut key.

void ResetKey();

Remarks

The function clears the edit control text. This includes any shortcut keys that the user pressed.
