備註

MouseHover 的一般用法是，當滑鼠暫時停留在形狀周圍的指定區域 (「停留矩形」(Hover Rectangle) 中時，顯示工具提示。引發這個事件所需的暫停時間是由 MouseHoverTime 屬性所指定 (以毫秒為單位)。

MouseHover 事件的定義和偵測與 MouseHoverSize 和 MouseHoverTime 屬性有關。

滑鼠事件依下列順序發生：

MouseEnter

MouseMove

MouseHover / MouseDown / MouseWheel

MouseUp

MouseLeave

Private Sub RectangleShape1_MouseEnter(ByVal sender As Object, _
 ByVal e As System.EventArgs) Handles RectangleShape1.MouseEnter
    ToolStripStatusLabel1.Text = "The mouse has entered the shape."
End Sub

Private Sub RectangleShape1_MouseHover(ByVal sender As Object, _
  ByVal e As System.EventArgs) Handles RectangleShape1.MouseHover
    ToolStripStatusLabel1.Text = "The mouse is paused over the shape."
End Sub

Private Sub RectangleShape1_MouseLeave(ByVal sender As Object, _
  ByVal e As System.EventArgs) Handles RectangleShape1.MouseLeave
    ToolStripStatusLabel1.Text = "The mouse has left the shape."
End Sub

Private Sub RectangleShape1_MouseMove(ByVal sender As Object, _
  ByVal e As System.Windows.Forms.MouseEventArgs) Handles _
  RectangleShape1.MouseMove
    ToolStripStatusLabel1.Text = "The mouse is over the shape."
End Sub

private void rectangleShape1_MouseEnter(object sender, System.EventArgs e)
{
    toolStripStatusLabel1.Text = "The mouse has entered the shape.";
}

private void rectangleShape1_MouseHover(object sender, System.EventArgs e)
{
    toolStripStatusLabel1.Text = "The mouse is paused over the shape.";
}

private void rectangleShape1_MouseLeave(object sender, System.EventArgs e)
{
    toolStripStatusLabel1.Text = "The mouse has left the shape.";
}
