如何在 WinForms 中的禁用面板上设置 WaitCursor 光标 [英] How to set WaitCursor cursor over disabled panel in WinForms

问题描述

我正在尝试这样做

panel.Enabled = false; // to disable all controls on panel at once
panel.Cursor = Cursors.WaitCursor;

并且调试器显示 panel.Cursor 是 WaitCursor，但是当我将鼠标移到面板上时，光标仍然是箭头.

and debugger shows that panel.Cursor is WaitCursor, but when I move a mouse over the panel, cursor is still Arrow.

panel.Update(); panel.Refresh(); // does not help

那么，如何解决它?

推荐答案

禁用的控件将不会接收 Windows 消息.最简单的方法是保持启用状态并以不同的方式处理禁用".

A disabled control will not receive Windows Messages. Easiest is to keep it enabled and handle "Disabled" a different way.

满足您特定需求的另一种方法是将下面的代码添加到按钮的父级 - 您可以优化例程以仅在需要更改时调用.

An alternative for your specific need is to add the code below on to the button's parent - you can optimize the routine to call only when changes are needed.

        this.MouseMove += (s, a) =>
                              {
                                  if (button2.Bounds.Contains(a.Location))
                                      this.Cursor = Cursors.WaitCursor;
                                  else
                                      this.Cursor = Cursors.Default;
                              };
