Contoh

Contoh kode berikut menunjukkan cara mengatur Textproperti , , Overflowdan TextDirection , dan menangani Click peristiwa. Untuk menjalankan contoh ini, tempelkan kode berikut ke dalam formulir yang berisi ToolStrip nama movingToolStrip dan panggilan InitializeMovingToolStrip di konstruktor formulir atau Load penanganan aktivitas.

ToolStripButton^ changeDirectionButton;

void InitializeMovingToolStrip()
{
    changeDirectionButton = gcnew ToolStripButton;
    movingToolStrip->AutoSize = true;
    movingToolStrip->RenderMode = ToolStripRenderMode::System;
    changeDirectionButton->TextDirection = 
        ToolStripTextDirection::Vertical270;
    changeDirectionButton->Overflow = 
        ToolStripItemOverflow::Never;
    changeDirectionButton->Text = "Change Alignment";
    movingToolStrip->Items->Add(changeDirectionButton);
    changeDirectionButton->Click += gcnew EventHandler(this, 
        &Form1::changeDirectionButtonClick);
}

void changeDirectionButtonClick(Object^ sender, EventArgs^ e)
{
    ToolStripItem^ item = (ToolStripItem^) sender;
    if ((item->TextDirection == ToolStripTextDirection::Vertical270) 
        || (item->TextDirection == ToolStripTextDirection::Vertical90))
    {
        item->TextDirection = ToolStripTextDirection::Horizontal;
        movingToolStrip->Raft = RaftingSides::Top;
    }
    else
    {
        item->TextDirection = 
            ToolStripTextDirection::Vertical270;
        movingToolStrip->Raft = RaftingSides::Left;
    }
}

internal ToolStripButton changeDirectionButton;

private void InitializeMovingToolStrip()
{
    movingToolStrip = new ToolStrip();

    changeDirectionButton = new ToolStripButton();

    movingToolStrip.AutoSize = true;
    movingToolStrip.RenderMode = ToolStripRenderMode.System;

    changeDirectionButton.TextDirection = ToolStripTextDirection.Vertical270;
    changeDirectionButton.Overflow = ToolStripItemOverflow.Never;
    changeDirectionButton.Text = "Change Alignment";
        movingToolStrip.Items.Add(changeDirectionButton);
}

private void changeDirectionButton_Click(object sender, EventArgs e)
{

    ToolStripItem item = (ToolStripItem)sender;

    if (item.TextDirection == ToolStripTextDirection.Vertical270 || item.TextDirection == ToolStripTextDirection.Vertical90)
    {
        item.TextDirection = ToolStripTextDirection.Horizontal;
        movingToolStrip.Dock = System.Windows.Forms.DockStyle.Top;
    }
    else
    {
        item.TextDirection = ToolStripTextDirection.Vertical270;
        movingToolStrip.Dock = System.Windows.Forms.DockStyle.Left;
    }
}

Friend WithEvents changeDirectionButton As ToolStripButton

Private Sub InitializeMovingToolStrip()
    changeDirectionButton = New ToolStripButton()

    movingToolStrip.AutoSize = True
    movingToolStrip.RenderMode = ToolStripRenderMode.System

    changeDirectionButton.TextDirection = ToolStripTextDirection.Vertical270
    changeDirectionButton.Overflow = ToolStripItemOverflow.Never
    changeDirectionButton.Text = "Change Alignment"
    movingToolStrip.Items.Add(changeDirectionButton)
End Sub


Public Sub changeDirectionButton_Click(ByVal sender As Object, _
    ByVal e As EventArgs) Handles changeDirectionButton.Click

    Dim item As ToolStripItem = CType(sender, ToolStripItem)

    If item.TextDirection = ToolStripTextDirection.Vertical270 _
        OrElse item.TextDirection = ToolStripTextDirection.Vertical90 Then

        item.TextDirection = ToolStripTextDirection.Horizontal
        movingToolStrip.Dock = System.Windows.Forms.DockStyle.Top
    Else
        item.TextDirection = ToolStripTextDirection.Vertical270
        movingToolStrip.Dock = System.Windows.Forms.DockStyle.Left
    End If

End Sub

Keterangan

Peristiwa Click meneruskan EventArgs ke penanganan aktivitasnya, sehingga hanya menunjukkan bahwa klik telah terjadi. Jika Anda memerlukan informasi mouse yang lebih spesifik (tombol, jumlah klik, rotasi roda, atau lokasi), gunakan MouseDown peristiwa dan MouseUp yang meneruskan MouseEventArgs ke penanganan aktivitas.

Klik dua kali ditentukan oleh pengaturan mouse sistem operasi pengguna. Pengguna dapat mengatur waktu antara klik tombol mouse yang harus dianggap klik ganda daripada dua klik. Peristiwa Click dimunculkan setiap kali kontrol diklik dua kali. Misalnya, jika Anda memiliki dua penanganan aktivitas untuk Click peristiwa dan DoubleClick dari Form, Click peristiwa dan DoubleClick dimunculkan saat formulir diklik dua kali dan kedua metode dipanggil. Jika item diklik dua kali yang tidak mendukung DoubleClick peristiwa, Click peristiwa mungkin dinaikkan dua kali.
