可以向表单标题添加工具提示 [英] Possible To Add a ToolTip to the Form Title

问题描述

在表单上，​​表单的标题是设计器文件中设置的文本.我遇到的问题是，当标题国际化时，标题会缩短并添加省略号.是否可以添加当我们将鼠标悬停在标题上时会显示的工具提示?因此，如果我将鼠标悬停在Form1"上，工具提示应显示Form1".

表单是用 C# 编写的.由于标题不是表单中的控件，所以无法设置tooltip.

有什么想法吗?

此外，有关处理 MDI 子表单的相关问题的更复杂方法，请参阅 Reza Aghaei 的这篇帖子，他现在也通过重构实现回答了这个问题.

On a Form, the title of the form is the Text that is set in the Designer file. The problem I am having is that when the title is internationalized, the title gets shortened and an ellipsis is added. Is it possible to add a tooltip that will display when we hover over the title? So if I am hovering over "Form1", a tooltip should display that says "Form1".

Form is written in C#. Since the title is not a control in the form, I can't set the tooltip.

Any ideas?

解决方案

One approach would be to do this:

using System.Drawing;
using System.Threading.Tasks;

public Form1()
{
    InitializeComponent();
    ImplementToolBarToolTip();
}
private readonly ToolTip _toolTip1 = new ToolTip();
private async void ImplementToolBarToolTip()
{
    while (!IsDisposed)
    {
        await Task.Delay(200);
        var right = Left + Width;
        var bottom = Top + 39;
        var x = Cursor.Position.X;
        var y = Cursor.Position.Y;
        if (IsDisposed) return;
        if (x > Left && x < right && y > Top && y < bottom)
        {
            _toolTip1.Show(Text, this, PointToClient(new Point(x, y)));
        }
        else _toolTip1.Hide(this);
    }
}

Note: If you would prefer not to show the tooltip when the user mouses over the Close, Minimize, or Maximise buttons on the far right, then subtract 149 from the right value:

var right = Left + Width - 149;
