如何使一个浮动控制 [英] How to make a floating control

问题描述

我想创建的花车（潜在的），它的边界之外是一个包含表单控件。这可能吗？我怎么可以这样做呢？

I would like to create a control the floats (potentially) outside the bounds of it's containing form. Is this possible? How may I do it?

这功能很像上下文菜单的唯一我需要能够将其他控件添加到它，例如按钮和图像。

This would function much like Context Menu's only I need to be able to add other controls to it such as buttons and images.

推荐答案

您想做的事情窗体的FormBorderStyle设置为无，如果你想让它表现得像一个上下文菜单，那么你就需要配合显示给适当的在主窗体的事件处理程序。简单的例子，从鼠标点击事件处理程序设置的位置，并呼吁展示如下：

You want a Form with it's FormBorderStyle set to None, if you want it to behave like a context menu then you'll need to tie showing it to the appropriate event handler in your main form. Simple example below of setting the location and calling show from a mouse click event handler.

MyForm form = new MyForm();
form.Location = PointToScreen(new Point(e.X, e.Y));
form.Show();
