表单间共享MenuStrip

Question

我有一个小小的问题和这个问题有关：How to create navigation inside program Form - noob再次提醒。

我试图在c#程序中创建一个导航，就像网站上的动态下拉菜单。我使用的是不同的C#表单，比如每一个都是不同的网页内容。

是否可以在窗体之间与导航共享菜单？(最简单的网页相似性:包含(‘menu.php’)-把所有的东西放在一个文件中，我在每个网页中嵌入)

否则，需要将菜单条复制到每个新表单(然后是menustrip更改，然后呢？)再复制一次？:)

Answer 1

您可以通过将选项卡与Srip连接起来，如下所示：

//make tabs invisible (so you wont see them changing)
private void HideAllTabsOnTabControl(TabControl theTabControl)
{
    theTabControl.Appearance = TabAppearance.FlatButtons;
    theTabControl.ItemSize = new Size(0, 1);
    theTabControl.SizeMode = TabSizeMode.Fixed;
}

//hide all tabs
private void hide_all_tabs() {
    Tab_content.TabPages.Remove(tabPage1);
    Tab_content.TabPages.Remove(tabPage2);
    Tab_content.TabPages.Remove(tabPage3);
    Tab_content.TabPages.Remove(tabPage4);
}
private void materiałyQCToolStripMenuItem_Click(object sender, EventArgs e)
{
    hide_all_tabs(); //hide everything
    Tab_content.TabPages.Add(tabPage1); //schow just first tab
}
private void analizatoryQCToolStripMenuItem_Click(object sender, EventArgs e)
{
    hide_all_tabs();
    Tab_content.TabPages.Add(tabPage2);
}
private void QCzDzisiajToolStripMenuItem_Click(object sender, EventArgs e)
{
    hide_all_tabs();
    Tab_content.TabPages.Add(tabPage3);
}
private void standlabToolStripMenuItem_Click(object sender, EventArgs e)
{
    hide_all_tabs();
    Tab_content.TabPages.Add(tabPage4);
}

例如，如果您希望在ContextMenu和主窗体MenuStrip之间共享项

​

​

没有项目的MenuStrip

​

​

ContextMenu项目

​

​

带有从ContextMenu复制的项目的ContextMenu

在主要形式上，您可以：

ToolStripMenuItem toolStripMoved;
ToolStripItem[] itemsArrayMoved;

private void Edit_DropDownOpening(object sender, EventArgs e)
{
    var doc = DockPanel.GetDocuments().FirstOrDefault(t => t.Visible) as DockDocument;
    if (doc != null)
    {
        toolStripMoved = doc.ContextMenuStrip.Items["Edit"] as ToolStripMenuItem;
        if (toolStripMoved != null)
        {
            var menu = (sender as ToolStripMenuItem);
            itemsArrayMoved = Helper.GetAllChildren(toolStripMoved);
            foreach (ToolStripItem item in itemsArrayMoved)
            {
                if (item.Name.Equals("Edit") == false)
                    menu.DropDownItems.Add(item);
            }
        }
    }
}

private void Edit_DropDownClosed(object sender, EventArgs e)
{
    if (toolStripMoved != null)
    {
        foreach (ToolStripItem item in itemsArrayMoved)
        {
            if (item.Name.Equals("Edit") == false)
                toolStripMoved.DropDownItems.Add(item);
        }
    }
}

static private ToolStripItem[] GetAllChildren(ToolStripItem item)
{
    List<ToolStripItem> Items = new List<ToolStripItem>() { item };
    if (item is ToolStripMenuItem)
        foreach (ToolStripItem i in ((ToolStripMenuItem)item).DropDownItems)
            Items.AddRange(GetAllChildren(i));
    else if (item is ToolStripSplitButton)
        foreach (ToolStripItem i in ((ToolStripSplitButton)item).DropDownItems)
            Items.AddRange(GetAllChildren(i));
    else if (item is ToolStripDropDownButton)
        foreach (ToolStripItem i in ((ToolStripDropDownButton)item).DropDownItems)
            Items.AddRange(GetAllChildren(i));
    return Items.ToArray();
}
