问题 要求当鼠标在图片框P1中移动时,立即在图片框中显示鼠标的位置坐标。下面能正确实现上述功能的事件过程是(  )。

选项 A、 Private Sub P1_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
Print X, Y
End Sub
B、Private Sub P1_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
Picture.Print X, Y
End Sub
C、Private Sub P1_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
P1.Print X, Y
End Sub
D、Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
P1.Print X, Y
End Sub

答案C

解析 当鼠标在图片框P1中移动时,就会触发P1的鼠标移动事件,即P1_MouseMove事件,故排除B选项;鼠标在图片框P1中移动时,立即在图片框中显示鼠标的位置坐标,说明是在图片框上输出数据,所以用P1的Print语句实现。故C选项正确。
