Detailed Description

Function Documentation

GetOriginalMousePosition()

void GUIAPI GetOriginalMousePosition	(	int *	x,
		int *	y
	)

Get the original mouse position.

Parameters

x	The pointer used to return the x coordinate of original mouse position.
y	The pointer used to return the y coordinate of original mouse position.

Returns

none.

Note

This function is available when _MGHAVE_MOUSECALIBRATE (option: –enable-mousecalibrate) defined.

Only call this function in MiniGUI-Standalone, MiniGUI-Threads, and the server (mginit) of MiniGUI-Processes. The behavior of this function will be undefined if you call it in a client of MiniGUI-Processes.

SetMouseCalibrationParameters()

BOOL GUIAPI SetMouseCalibrationParameters	(	const POINT *	src_pts,
		const POINT *	dst_pts
	)

Set the parameters for doing mouse calibration.

This function set the parameters for doing mouse calibration. You should pass five source points and five destination points.

Normally, the points should be the upper-left, upper-right, lower-right, lower-left, and center points on the touch panel. The source point is the coordinates before calibrating, and the destination point is the desired coordinates after calibrating.

This function will try to evaluate a matrix to calibrate. If the points are okay, MiniGUI will do the calibration after getting a point from the underlay IAL engine.

Parameters

src_pts	The pointer to an array of five source points.
dst_pts	The pointer to an array of five destination points.

Returns

TRUE for success, FALSE for bad arguments.
