如何创建属于标签页的一组控件的全屏视图

Question

我想知道创建一个tabpage控件的全屏视图的正确方法是什么.此页面具有其他控件,并且该控件具有已订阅的各种事件.我正在尝试创建一个新的全屏表单并将选项卡的所有控件复制到该表单,但是使用这种方法我需要将每个控件重新订阅到相应的处理程序.如果我只添加引用,则订阅仍然存在,但是当全屏表单关闭时,引用的复制控件也将丢失.

这可以通过Winforms对重新控制控件的支持来优雅地完成.您可以将其移动到全屏显示的临时表单.所有正常的事件处理程序仍然照常工作.这是一个示例实现,适用于任何控件:

    public static void ShowFullScreen(Control ctl) {
        // Setup host form to be full screen
        var host = new Form();
        host.FormBorderStyle = FormBorderStyle.None;
        host.WindowState = FormWindowState.Maximized;
        host.ShowInTaskbar = false;
        // Save properties of control
        var loc = ctl.Location;
        var dock = ctl.Dock;
        var parent = ctl.Parent;
        var form = parent;
        while (!(form is Form)) form = form.Parent;
        // Move control to host
        ctl.Parent = host;
        ctl.Location = Point.Empty;
        ctl.Dock = DockStyle.Fill;
        // Setup event handler to restore control back to form
        host.FormClosing += delegate {
            ctl.Parent = parent;
            ctl.Dock = dock;
            ctl.Location = loc;
            form.Show();
        };
        // Exit full screen with escape key
        host.KeyPreview = true;
        host.KeyDown += (KeyEventHandler)((s, e) => {
            if (e.KeyCode == Keys.Escape) host.Close();
        });
        // And go full screen
        host.Show();
        form.Hide();
    }

样品用法:

    private void button1_Click(object sender, EventArgs e) {
        ShowFullScreen(tabControl1);
    }
