Function Documentation

void gslc_ElemXKeyPadBtnEvt_Alpha	(	void *	pvKeyPad,
		uint8_t	nId,
		gslc_tsXKeyPadResult *	psResult
	)

Callback function activated when a key has been pressed.

This callback is used to enable the KeyPad variant to handle any events associated with the key press and update any internal state.

• The callback is also used to determine whether any redraw actions need to be taken.

Parameters

[in]	pvKeyPad	Void ptr to the KeyPad
[in]	nId	KeyPad key ID
[out]	psResult	The returned state vector (including redraw)

Returns

none

gslc_tsXKeyPadCfg_Alpha gslc_ElemXKeyPadCfgInit_Alpha

(

)

Initialize the KeyPad config structure.

• This routine should be called to initialize the configuration data structure before calling any of the KeyPad config APIs

Returns

Initialized KeyPad config structure

gslc_tsElemRef* gslc_ElemXKeyPadCreate_Alpha	(	gslc_tsGui *	pGui,
		int16_t	nElemId,
		int16_t	nPage,
		gslc_tsXKeyPad *	pXData,
		int16_t	nX0,
		int16_t	nY0,
		int8_t	nFontId,
		gslc_tsXKeyPadCfg_Alpha *	pConfig
	)

Create a KeyPad Element.

Parameters

[in]	pGui	Pointer to GUI
[in]	nElemId	Element ID to assign (0..16383 or GSLC_ID_AUTO to autogen)
[in]	nPage	Page ID to attach element to
[in]	pXData	Ptr to extended element data structure
[in]	nX0	X KeyPad Starting Coordinate
[in]	nY0	Y KeyPad Starting Coordinate
[in]	nFontId	Font ID to use for drawing the element
[in]	pConfig	Ptr to config options

Returns

Pointer to Element or NULL if failure

void gslc_ElemXKeyPadLabelGet_Alpha	(	void *	pvKeyPad,
		uint8_t	nId,
		uint8_t	nStrMax,
		char *	pStr
	)

Callback function to retrieve the label associated with a KeyPad button.

This is called during the drawing of the KeyPad layout.

Parameters

[in]	pvKeyPad	Void ptr to the KeyPad
[in]	nId	KeyPad key ID
[in]	nStrMax	Maximum length of return string (including NULL)
[out]	pStr	Buffer for the returned label

Returns

none

void gslc_ElemXKeyPadReset_Alpha

(

void *

pvConfig

)

Callback function to reset internal state.

Parameters

[in]

pvConfig

Void ptr to the KeyPad config

Returns

none

void gslc_ElemXKeyPadStyleGet_Alpha	(	void *	pvKeyPad,
		uint8_t	nId,
		bool *	pbVisible,
		gslc_tsColor *	pcolTxt,
		gslc_tsColor *	pcolFrame,
		gslc_tsColor *	pcolFill,
		gslc_tsColor *	pcolGlow
	)

Callback function to retrieve the style associated with a KeyPad button.

This is called during the drawing of the KeyPad layout.

• This function is used to assign the color and visibility state of the keys at runtime.
• This function can also be used to change the appearance dynamically, according to internal state (eg. dimmed buttons).

Parameters

[in]	pvKeyPad	Void ptr to the KeyPad
[in]	nId	KeyPad key ID
[out]	pbVisible	The returned visibility state
[out]	pcolTxt	The returned text color
[out]	pcolFrame	The returned key's frame color
[out]	pcolFill	The returned key's fill color
[out]	pcolGlow	The returned key's fill color when highlighted

Returns

none

void gslc_ElemXKeyPadTxtInit_Alpha

(

void *

pvKeyPad

)

Callback function to update internal state whenever the text field is manually set via gslc_ElemXKeyPadValSet().

• This is used to ensure any KeyPad variant state can be kept in sync with the text string.
• For example, if a numeric KeyPad is initiaized with a string that contains a minus sign, an internal negation flag might be set.

Parameters

[in]

pvKeyPad

Void ptr to the KeyPad

Returns

none
