Comment : utiliser des contrôles ToolStripPanel pour MDI

  • Article

ToolStripPanel fournit une flexibilité pour les applications d'interface multidocument (MDI) à l'aide de la méthode Join.

Exemple

L'exemple de code suivant montre comment utiliser des contrôles ToolStripPanel pour MDI.

// This code example demonstrates how to use ToolStripPanel
// controls with a multiple document interface (MDI).
public class Form1 : Form
{
    public Form1()
    {
        // Make the Form an MDI parent.
        this.IsMdiContainer = true;

        // Create ToolStripPanel controls.
        ToolStripPanel tspTop = new ToolStripPanel();
        ToolStripPanel tspBottom = new ToolStripPanel();
        ToolStripPanel tspLeft = new ToolStripPanel();
        ToolStripPanel tspRight = new ToolStripPanel();

        // Dock the ToolStripPanel controls to the edges of the form.
        tspTop.Dock = DockStyle.Top;
        tspBottom.Dock = DockStyle.Bottom;
        tspLeft.Dock = DockStyle.Left;
        tspRight.Dock = DockStyle.Right;

        // Create ToolStrip controls to move among the
        // ToolStripPanel controls.

        // Create the "Top" ToolStrip control and add
        // to the corresponding ToolStripPanel.
        ToolStrip tsTop = new ToolStrip();
        tsTop.Items.Add("Top");
        tspTop.Join(tsTop);

        // Create the "Bottom" ToolStrip control and add
        // to the corresponding ToolStripPanel.
        ToolStrip tsBottom = new ToolStrip();
        tsBottom.Items.Add("Bottom");
        tspBottom.Join(tsBottom);

        // Create the "Right" ToolStrip control and add
        // to the corresponding ToolStripPanel.
        ToolStrip tsRight = new ToolStrip();
        tsRight.Items.Add("Right");
        tspRight.Join(tsRight);

        // Create the "Left" ToolStrip control and add
        // to the corresponding ToolStripPanel.
        ToolStrip tsLeft = new ToolStrip();
        tsLeft.Items.Add("Left");
        tspLeft.Join(tsLeft);

        // Create a MenuStrip control with a new window.
        MenuStrip ms = new MenuStrip();
        ToolStripMenuItem windowMenu = new ToolStripMenuItem("Window");
        ToolStripMenuItem windowNewMenu = new ToolStripMenuItem("New", null, new EventHandler(windowNewMenu_Click));
        windowMenu.DropDownItems.Add(windowNewMenu);
        ((ToolStripDropDownMenu)(windowMenu.DropDown)).ShowImageMargin = false;
        ((ToolStripDropDownMenu)(windowMenu.DropDown)).ShowCheckMargin = true;

        // Assign the ToolStripMenuItem that displays
        // the list of child forms.
        ms.MdiWindowListItem = windowMenu;

        // Add the window ToolStripMenuItem to the MenuStrip.
        ms.Items.Add(windowMenu);

        // Dock the MenuStrip to the top of the form.
        ms.Dock = DockStyle.Top;

        // The Form.MainMenuStrip property determines the merge target.
        this.MainMenuStrip = ms;

        // Add the ToolStripPanels to the form in reverse order.
        this.Controls.Add(tspRight);
        this.Controls.Add(tspLeft);
        this.Controls.Add(tspBottom);
        this.Controls.Add(tspTop);

        // Add the MenuStrip last.
        // This is important for correct placement in the z-order.
        this.Controls.Add(ms);
    }

    // This event handler is invoked when
    // the "New" ToolStripMenuItem is clicked.
    // It creates a new Form and sets its MdiParent
    // property to the main form.
    void windowNewMenu_Click(object sender, EventArgs e)
    {
        Form f = new Form();
        f.MdiParent = this;
        f.Text = "Form - " + this.MdiChildren.Length.ToString();
        f.Show();
    }
}
