Functions

hide()

void QAhiScreenCursor::hide ( )

virtual

Hides the cursor from the screen.

See also

show()

Reimplemented from QScreenCursor.

Definition at line 189 of file qscreenahi_qws.cpp.

Referenced by QAhiScreenCursor().

{
    AhiDispCursorState(context, AhiCursor1, AhiCursorStateOff, 0);
    QScreenCursor::hide();
}

move()

void QAhiScreenCursor::move ( int  x, int  y  )

virtual

Moves the mouse cursor to the given position, i.e., (x, y).

Note that the given position defines the top-left corner of the cursor's image, i.e., not the cursor's hot spot (the position of the associated mouse events).

See also

set()

Reimplemented from QScreenCursor.

Definition at line 170 of file qscreenahi_qws.cpp.

{
    AhiPoint_t pos = { x, y };
    AhiSts_t status = AhiDispCursorPos(context, AhiCursor1, &pos, 0);
    if (status != AhiStsOk)
        qWarning("QAhiScreenCursor::move(): error setting mouse position: %x",
                 status);
    QScreenCursor::move(x, y);
}

set()

void QAhiScreenCursor::set ( const QImage &  image, int  hotx, int  hoty  )

virtual

Sets the cursor's image to be the given image.

The hotx and hoty parameters define the cursor's hot spot, i.e., the point within the cursor's image that will be the position of the associated mouse events.
