gslc_tsElemRef* gslc_ElemXRadialCreate	(	gslc_tsGui *	pGui,
		int16_t	nElemId,
		int16_t	nPage,
		gslc_tsXRadial *	pXData,
		gslc_tsRect	rElem,
		int16_t	nMin,
		int16_t	nMax,
		int16_t	nVal,
		gslc_tsColor	colGauge
	)

Create a Radial Gauge Element.

• Draws a gauge element that represents a proportion (nVal) between nMin and nMax.

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]	rElem	Rectangle coordinates defining gauge size
[in]	nMin	Minimum value of gauge for nVal comparison
[in]	nMax	Maximum value of gauge for nVal comparison
[in]	nVal	Starting value of gauge
[in]	colGauge	Color for the gauge indicator

Returns

Pointer to Element reference or NULL if failure

bool gslc_ElemXRadialDraw	(	void *	pvGui,
		void *	pvElemRef,
		gslc_teRedrawType	eRedraw
	)

Draw a gauge element on the screen.

• Called from gslc_ElemDraw()

Parameters

[in]	pvGui	Void ptr to GUI (typecast to gslc_tsGui*)
[in]	pvElemRef	Void ptr to Element reference (typecast to gslc_tsElemRef*)
[in]	eRedraw	Redraw mode

Returns

true if success, false otherwise

bool gslc_ElemXRadialDrawRadial	(	gslc_tsGui *	pGui,
		gslc_tsElemRef *	pElemRef,
		gslc_teRedrawType	eRedraw
	)

Helper function to draw a gauge with style: radial.

• Called from gslc_ElemXRadialDraw()

Parameters

[in]	pGui	Ptr to GUI
[in]	pElemRef	Ptr to Element reference
[in]	eRedraw	Redraw status

Returns

true if success, false otherwise

void gslc_ElemXRadialDrawRadialHelp	(	gslc_tsGui *	pGui,
		int16_t	nX,
		int16_t	nY,
		uint16_t	nArrowLen,
		uint16_t	nArrowSz,
		int16_t	n64Ang,
		bool	bFill,
		gslc_tsColor	colFrame
	)

void gslc_ElemXRadialSetFlip	(	gslc_tsGui *	pGui,
		gslc_tsElemRef *	pElemRef,
		bool	bFlip
	)

Set a Gauge element's rotation direction.

• Setting bFlip reverses the rotation direction
• Default rotation is clockwise. When bFlip is set, uses counter-clockwise

Parameters

[in]	pGui	Pointer to GUI
[in]	pElemRef	Pointer to Element reference
[in]	bFlip	If set, reverse direction of rotation from default

Returns

none

void gslc_ElemXRadialSetIndicator	(	gslc_tsGui *	pGui,
		gslc_tsElemRef *	pElemRef,
		gslc_tsColor	colGauge,
		uint16_t	nIndicLen,
		uint16_t	nIndicTip,
		bool	bIndicFill
	)

Configure the appearance of the Gauge indicator.

Parameters

[in]	pGui	Pointer to GUI
[in]	pElemRef	Pointer to Element reference
[in]	colGauge	Color of the indicator
[in]	nIndicLen	Length of the indicator
[in]	nIndicTip	Size of the indicator tip
[in]	bIndicFill	Fill in the indicator if true

Returns

none

void gslc_ElemXRadialSetTicks	(	gslc_tsGui *	pGui,
		gslc_tsElemRef *	pElemRef,
		gslc_tsColor	colTick,
		uint16_t	nTickCnt,
		uint16_t	nTickLen
	)

Configure the appearance of the Gauge ticks.

Parameters

[in]	pGui	Pointer to GUI
[in]	pElemRef	Pointer to Element reference
[in]	colTick	Color of the gauge ticks
[in]	nTickCnt	Number of ticks to draw around / along gauge
[in]	nTickLen	Length of the tick marks to draw

Returns

none

void gslc_ElemXRadialSetVal	(	gslc_tsGui *	pGui,
		gslc_tsElemRef *	pElemRef,
		int16_t	nVal
	)

Update a Gauge element's current value.

• Note that min & max values are assigned in create()

Parameters

[in]	pGui	Pointer to GUI
[in]	pElemRef	Pointer to Element reference
[in]	nVal	New value to show in gauge

Returns

none
