STICKYKEYS info  Overview  Group

The STICKYKEYS structure contains information about the StickyKeys accessibility feature. When the StickyKeys feature is on, the user can press a modifier key (SHIFT, CTRL, or ALT) and then another key in sequence rather than at the same time, to enter shifted (modified) characters and other key combinations.

typedef struct tagSTICKYKEYS {     // sk 

    DWORD cbSize; 

    DWORD dwFlags; 

} STICKYKEYS, *LPSTICKYKEYS; 

 

Members

cbSize

Specifies the size, in bytes, of this structure.

dwFlags

A set of bit-flags that specify properties of the StickyKeys feature. The following bit-flag values are defined:

Value	Meaning
SKF_AUDIBLEFEEDBACK	If this flag is set, the system plays a sound when the user latches, locks, or releases modifier keys using the StickyKeys feature.
SKF_AVAILABLE	If this flag is set, the StickyKeys feature is available.
SKF_CONFIRMHOTKEY	Windows 95 only: A confirmation dialog appears when the StickyKeys feature is activated by using the hot key.
SKF_HOTKEYACTIVE	If this flag is set, the user can turn the StickyKeys feature on and off by pressing the SHIFT key five times.
SKF_HOTKEYSOUND	If this flag is set, the system plays a siren sound when the user turns the StickyKeys feature on or off by using the hot key.
SKF_INDICATOR	Windows 95 only: A visual indicator should be displayed when the StickyKeys feature is on.
SKF_STICKYKEYSON	If this flag is set, the StickyKeys feature is on.
SKF_TRISTATE	If this flag is set, pressing a modifier key twice in a row locks down the key until the user presses it a third time.
SKF_TWOKEYSOFF	If this flag is set, releasing a modifier key that has been pressed in combination with any other key turns off the StickyKeys feature.

Remarks

An application uses a STICKYKEYS structure when calling the SystemParametersInfo function with the wAction parameter set to SPI_GETSTICKYKEYS or SPI_SETSTICKYKEYS. When using SPI_GETSTICKYKEYS, an application must specify the cbSize member of the STICKYKEYS structure; the SystemParametersInfo function fills the remaining members. You must specify all structure members when using the SPI_SETSTICKYKEYS value.
