gslc_tsElemRef* gslc_ElemXRampCreate	(	gslc_tsGui *	pGui,
		int16_t	nElemId,
		int16_t	nPage,
		gslc_tsXRamp *	pXData,
		gslc_tsRect	rElem,
		int16_t	nMin,
		int16_t	nMax,
		int16_t	nVal,
		gslc_tsColor	colGauge,
		bool	bVert
	)

Create a Ramp 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
[in]	bVert	Flag to indicate vertical vs horizontal action (true = vertical, false = horizontal)

Returns

Pointer to Element reference or NULL if failure

bool gslc_ElemXRampDraw	(	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_ElemXRampDrawHelp	(	gslc_tsGui *	pGui,
		gslc_tsElemRef *	pElemRef,
		gslc_teRedrawType	eRedraw
	)

Helper function to draw a gauge with style: ramp.

• Called from gslc_ElemXRampDraw()

Parameters

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

Returns

true if success, false otherwise

void gslc_ElemXRampSetVal	(	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
