ToolStripManager 未恢复 Toolstrips 的位置

Question

ToolStripManager 不会按预期将我的 Toolstrip 恢复到以前的位置。我创建了一个非常简单的应用程序来演示。 I 在 ToolStrip 容器中包含 4 个可移动的 Toolstrip。我移动工具条，将它们从上到下排列为 4-3-2-1（图 A）。然后关闭应用程序。当我重新打开它时，它们的顺序如图 B 所示。

这是简单的代码。我已验证 LoadSettings 和 SaveSettings 方法调用中使用的 Key 是相同的字符串。

namespace ZT2
{
    public partial class Form1 : Form
    {
        string keyName = "abc";
        public Form1()
        {
            InitializeComponent();
            keyName = Application.ProductName + this.Name + "xyz";
            ToolStripManager.LoadSettings(this, keyName);
        }

        private void Form1_FormClosing(object sender, FormClosingEventArgs e)
        {
            ToolStripManager.SaveSettings(this, keyName);
        }
    }
}

通过以下方式保存表单关闭设置：

ToolStripManager.SaveSettings(this);

通过以下方式加载表单加载中的设置：

ToolStripManager.LoadSettings(this);

抱歉太快了...

您必须将其保存在配置文件或其他位置的某个位置，并在每次显示时检查这些值。

Answer 3

ToolStripContainer 的一个问题是您不能只设置包含 ToolStrip 的位置，因为容器总是检查容器中的其他 ToolStrip。

如果您在设计时没有将 ToolStrips 放入容器中，它可以正常工作。 您只需要一个函数来初始化它们一次。

另一种可能性是在调用 ToolStripManager.LoadSettings 函数之前将每个 Toolstrip 的父属性设置为 null

Answer 4

以防万一其他人最终陷入 ToolStripManager 地狱，这是我的解决方案。基本上，它完全使用 ToolStripContainer 和 ToolStripManager 进行导航，并通过用户设置和继承 ToolStripPanel（可通过 VS Designer 放置）的自定义控件来保留 ToolStrip 状态（位置和可见性）。这还会保留多个 ToolStripPanel，其中在面板之间拖动 ToolStrip。注意：它不执行 ToolStripManager 的所有其他功能，例如保留 ToolStrip 控件的顺序。

它可能需要一些重构，但你已经死了很长时间了，对吧？
