hotspot()

QPoint QPlatformCursorImage::hotspot ( ) const

inline

Return the cursor's hotspot.

Here is the caller graph for this function:

set() [1/3]

void QPlatformCursorImage::set	(	const QImage &	image,
		int	hx,
		int	hy
	)

Sets the cursor image to the given image, with the hotspot at the point specified by (hx, hy).

Here is the call graph for this function:

set() [2/3]

void QPlatformCursorImage::set	(	const uchar *	data,
		const uchar *	mask,
		int	width,
		int	height,
		int	hx,
		int	hy
	)

Sets the cursor image to the graphic represented by the combination of data and mask, with dimensions given by width and height and a hotspot at the point specified by (hx, hy).

The image data specified by data must be supplied in the format described by QImage::Format_Indexed8.

The corresponding mask data specified by mask must be supplied in a character array containing packed 1 bit per pixel format data, with any padding bits at the end of the array. Bits of value 0 represent transparent pixels in the image data.

void QPlatformCursorImage::set

(

Qt::CursorShape

id

)

Calling this method sets the cursor image to the specified shape.

id is one of the defined Qt::CursorShape values.

If id is invalid, Qt::BitmapCursor, or unknown by the implementation, Qt::ArrowCursor is used instead.
