REPOST：按钮上的弹出窗体 [英] REPOST: Popup form on button
问题描述
嗨 - 这是上周末发布的，遗憾的是没有解决。发布的
解决方案几乎可以使用，但是在每晚工作代码的另外5天后，我不会再领先了。
如果你有什么想法我真的很想听他们。

我想在一个按钮上显示一个美化的弹出/上下文菜单，只显示当按下按钮时按下鼠标按钮时
，并且当
鼠标按钮随处可见。这是一个完整的描述。
当在Button1上按下鼠标按钮时，我想要显示
弹出窗体（formPopup的一个实例）。如果鼠标
按钮在任何地方发布，光标可以在任何地方，即使在另一个应用程序或桌面或其他地方，也可以是
，
我希望隐藏弹出窗体。我的代码意味着
如果我将光标移离显示窗体，然后释放鼠标按钮，那么窗体并不总是隐藏的。我还想要
来捕获formPopup实例中的各种事件，例如
mouseenter等用于该窗体上的控件。通过添加
Button1.Capture = True，可以捕获formPopup
实例中的事件。

这是我已经拥有的完整代码。
1.启动Visual Studio .Net 2003并创建一个新的winforms
应用程序。
2.使用VS IDE工具栏在表单上放置一个新按钮Button1。
3.粘贴以下代码

Armin：
我也认为这已经完成并且已经粉碎了。看看
它出现的原始线程他还想在弹出窗体上显示
陷阱按钮事件。
Colin：
试试这个（代码如下）。关键代码在
formPopup_MouseLeave中。如果我理解你所描述的用户
界面，你必须有一个非常好的理由想要编码这种行为。对于
它的价值，我发现它很烦人而且不是什么东西
我会把它放到我的任何应用程序中。
请注意，MouseLeave不是''离开''
a控制权的唯一方法！你需要让它更健壮。

Hi - this was posted last weekend and unfortunately not resolved. The
solutions that were posted almost worked but after another 5 days of
working on the code everynight, I am not further ahead.

I want a glorified popup/context menu on a button that shows only when
the mouse button is pressed over the button, and disappears when the
mouse button is released anywhere. Here''s a full description.
When the mouse button is depressed over Button1, I want the
popup form (an instance of formPopup) to show. If the mouse
button is released anywhere, the cursor could be anywhere,
even over another application or on the desktop or somewhere else,
I want the popup form to be hidden. The code I have means that
if I move the cursor away from the display form, then release
the mouse button, the form isn''t always hidden. I also want
to trap various events in the instance of formPopup, such as
mouseenter etc for controls on that form. By adding
Button1.Capture=True, no events in the instance of formPopup
can be caught.

Armin:
I too thought this was done and dusted. Looking at
the original thread it appears he also wants to
trap button events on the popup form.
Colin:
Try this (the code is below). The key code is in
formPopup_MouseLeave. If I understand the user
interface you are describing, you must have a really
good reason for wanting to code this behaviour. For
what it''s worth, I find it annoying and not something
I would put into any of my applications.
Note that MouseLeave is not the only way to ''leave''
a control ! You will need to make it more robust.

Try this out Colin. It worked when I tried it. You need to set the button
capture to True. Then create a rect of the button to see if the point is in
or out of the button. Also, why do you have Button1_MouseUp handling the
f.mouseup? Remove it and it will work.
