範例

以下範例說明如何在控制項上設定該 FlowDirection 屬性 FlowLayoutPanel 。 此程式碼範例是控制項所提供 FlowLayoutPanel 更大範例的一部分。

private:
    void flowTopDownBtn_CheckedChanged(System::Object^ sender,
        System::EventArgs^ e)
    {
        this->flowLayoutPanel1->FlowDirection = FlowDirection::TopDown;
    }

private:
    void flowBottomUpBtn_CheckedChanged(System::Object^ sender,
        System::EventArgs^ e)
    {
        this->flowLayoutPanel1->FlowDirection = FlowDirection::BottomUp;
    }

private:
    void flowLeftToRight_CheckedChanged(System::Object^ sender,
        System::EventArgs^ e)
    {
        this->flowLayoutPanel1->FlowDirection =
            FlowDirection::LeftToRight;
    }

private:
    void flowRightToLeftBtn_CheckedChanged(
        System::Object^ sender, System::EventArgs^ e)
    {
        this->flowLayoutPanel1->FlowDirection =
            FlowDirection::RightToLeft;
    }

private void flowTopDownBtn_CheckedChanged(
    System.Object sender, 
    System.EventArgs e)
{
    this.FlowLayoutPanel1.FlowDirection = FlowDirection.TopDown;
}

private void flowBottomUpBtn_CheckedChanged(
    System.Object sender, 
    System.EventArgs e)
{
    this.FlowLayoutPanel1.FlowDirection = FlowDirection.BottomUp;
}

private void flowLeftToRight_CheckedChanged(
    System.Object sender, 
    System.EventArgs e)
{
    this.FlowLayoutPanel1.FlowDirection = FlowDirection.LeftToRight;
}

private void flowRightToLeftBtn_CheckedChanged(
    System.Object sender, 
    System.EventArgs e)
{
    this.FlowLayoutPanel1.FlowDirection = FlowDirection.RightToLeft;
}

Private Sub flowTopDownBtn_CheckedChanged( _
ByVal sender As System.Object, _
ByVal e As System.EventArgs) _
Handles flowTopDownBtn.CheckedChanged

    Me.FlowLayoutPanel1.FlowDirection = FlowDirection.TopDown

End Sub

Private Sub flowBottomUpBtn_CheckedChanged( _
ByVal sender As System.Object, _
ByVal e As System.EventArgs) _
Handles flowBottomUpBtn.CheckedChanged

    Me.FlowLayoutPanel1.FlowDirection = FlowDirection.BottomUp

End Sub

Private Sub flowLeftToRight_CheckedChanged( _
ByVal sender As System.Object, _
ByVal e As System.EventArgs) _
Handles flowLeftToRight.CheckedChanged

    Me.FlowLayoutPanel1.FlowDirection = FlowDirection.LeftToRight

End Sub

Private Sub flowRightToLeftBtn_CheckedChanged( _
ByVal sender As System.Object, _
ByVal e As System.EventArgs) _
Handles flowRightToLeftBtn.CheckedChanged

    Me.FlowLayoutPanel1.FlowDirection = FlowDirection.RightToLeft

End Sub

備註

列 FlowDirection 舉描述了連續 UI 元素（通常是控制項）在設計表面或容器（如表單）上的流動方向。 此列舉用於線性佈局容器，如 FlowLayoutPanel，這些容器將這些資訊內部儲存在 FlowLayoutPanel.FlowDirection 屬性中。

當 FlowDirection 新控制項加入支援容器時，預設會將新控制點放置在哪裡。 容器的流向，以及AnchorDock每個包含控制項的性質，決定了當容器重新調整大小時控制點的重新排列。

控制項 FlowLayoutPanel 為其子控制項提供屬性 FlowBreak 。 將屬性值 FlowBreak 設為 時 true ，控制 FlowLayoutPanel 項會停止依目前流向排列控制項，並繞行到下一列或下一欄。
