Functions

addCursor()

(

QScreenCursor *

cursor

)

Definition at line 135 of file qscreenmulti_qws.cpp.

Referenced by QMultiScreen::initDevice(), and ~QMultiScreenCursor().

{
    cursors.append(cursor);
}

hide()

void QMultiScreenCursor::hide ( )

virtual

Hides the cursor from the screen.

See also

show()

Reimplemented from QScreenCursor.

Definition at line 129 of file qscreenmulti_qws.cpp.

Referenced by ~QMultiScreenCursor().

{
    if (currentCursor)
        currentCursor->hide();
}

move()

void QMultiScreenCursor::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).

        }

        newCursor->move(x, y);

        setCurrentCursor(newCursor);
    }
}

set()

void QMultiScreenCursor::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.
