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	The square box that bounds the ring element. If a rectangular region is provided, then the ring control will be centered in the long axis.
[in]	pStrBuf	String buffer to use for gauge inner text
[in]	nStrBufMax	Maximum length of string buffer (pStrBuf)
[in]	nFontId	Font ID to use for text display

Returns: Pointer to Element reference or NULL if failure

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

Draw the template 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

void gslc_ElemXRingGaugeSetAngleRange	(	gslc_tsGui *	pGui,
		gslc_tsElemRef *	pElemRef,
		int16_t	nStart,
		int16_t	nRange,
		bool	bClockwise
	)

Defines the angular range of the gauge, including both the active and inactive regions.

nStart defines the angle at the beginning of the active region.
The current position marks the end of the active region and the beginning of the inactive region.
nRange defines the angular range from the start of the active region to the end of the inactive region. In most cases, a range of 360 degrees is used.
All angles are measured in units of degrees.
Angles are measured with 0 at the top, 90 towards the right, 180 towards the bottom, 270 towards the left, etc.

Parameters

[in]	pGui	Pointer to GUI
[in]	pElemRef	Pointer to Element reference
[in]	nStart	Define angle of start of active region (measured in degrees)
[in]	nRange	Define angular range from strt of active region to end of the inactive region (measured in degrees)
[in]	bClockwise	Defines the direction in which the active region grows (true for clockwise) [FORCED TRUE, FOR FUTURE IMPLEMENTATION]

Returns: none

void gslc_ElemXRingGaugeSetColorActiveFlat	(	gslc_tsGui *	pGui,
		gslc_tsElemRef *	pElemRef,
		gslc_tsColor	colActive
	)

Defines the color of the active region to be a flat (constant) color.

Parameters

[in]	pGui	Pointer to GUI
[in]	pElemRef	Pointer to Element reference
[in]	colActive	Color of active region

Returns: none

void gslc_ElemXRingGaugeSetColorActiveGradient	(	gslc_tsGui *	pGui,
		gslc_tsElemRef *	pElemRef,
		gslc_tsColor	colStart,
		gslc_tsColor	colEnd
	)

Defines the color of the active region to be a gradient using two color stops.

The active region will be filled according to the proportion between nMin and nMax. The gradient is defined by a linear RGB blend between the two color stops(colStart and colEnd)

Parameters

[in]	pGui	Pointer to GUI
[in]	pElemRef	Pointer to Element reference
[in]	colStart	Starting color of gradient fill
[in]	colEnd	Ending color of gradient fill

Returns: none

void gslc_ElemXRingGaugeSetColorInactive	(	gslc_tsGui *	pGui,
		gslc_tsElemRef *	pElemRef,
		gslc_tsColor	colInactive
	)

Defines the color of the inactive region to be a flat (constant) color.

The inactive color is often set to be the same as the background but it can be set to a different color to indicate the remainder of the value range that is yet to be filled.

Parameters

[in]	pGui	Pointer to GUI
[in]	pElemRef	Pointer to Element reference
[in]	colInactive	Color of inactive region

Returns: none

void gslc_ElemXRingGaugeSetQuality	(	gslc_tsGui *	pGui,
		gslc_tsElemRef *	pElemRef,
		uint16_t	nSegments
	)

Sets the quality of the ring drawing by defining the number of segments that are used when rendering a 360 degree gauge.The larger the number, the more segments are used and the smoother the curve.

A larger ring gauge may need a higher quality number to maintain a smoothed curve appearance.

Parameters

[in]	pGui	Pointer to GUI
[in]	pElemRef	Pointer to Element reference
[in]	nSegments	Number of arc segments to render a complete circle. The higher the value, the smoother the ring. Note that 360/nSegments should be an integer result, thus the allowable quality settings are: 360 (max quality), 180, 120, 90, 72, 60, 45, 40, 36 (low quality), etc.

Returns: none

void gslc_ElemXRingGaugeSetThickness	(	gslc_tsGui *	pGui,
		gslc_tsElemRef *	pElemRef,
		int8_t	nThickness
	)

Defines the thickness of the ring arcs.

More specifically, it defines the reduction in radius from the outer radius to the inner radius in pixels.

Default thickness is 10 pixels

Parameters

[in]	pGui	Pointer to GUI
[in]	pElemRef	Pointer to Element reference
[in]	nThickness	Thickness of ring

Returns: none

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

Set an Ring Gauge current indicator value.

Updates the current value of the ring gauge. The active region will be drawn up to the position defined by nVal within the value range defined by SetValRange(nMin,nMax). A SetVal() close to nMin will cause a very small active region to be drawn and a large remainder drawn in the inactive color, whereas a SetVal() close to nMax will cause a more complete active region to be drawn.When SetVal() equals nMax, the entire angular range will be drawn in the active color (and no inactive region).

Parameters

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

Returns: none

void gslc_ElemXRingGaugeSetValRange	(	gslc_tsGui *	pGui,
		gslc_tsElemRef *	pElemRef,
		int16_t	nValMin,
		int16_t	nValMax
	)

Defines the range of values that may be passed into SetVal(), used to scale the input to SetVal().

Default is 0..100.

Parameters

[in]	pGui	Pointer to GUI
[in]	pElemRef	Pointer to Element reference
[in]	nValMin	Minimum value
[in]	nValMax	Maximum value

Returns: none
