将TPopupMenu对齐到窗体的右侧？ [英] Align a TPopupMenu to the right hand side of the form?

问题描述

TPopupMenu如何与表单的右侧对齐？问题是，在调用 Popup（X，Y：Integer）之前，似乎没有办法获取弹出菜单的宽度。

我试图得到类似于Chrome中系统菜单的行为。

解决方案

你也可以设置 对齐 到 paRight 并使用ClientToScreen调用

  Point（ClientWidth  -  1，0））do 
 Popup（X，Y）; 
  

How can a TPopupMenu be aligned to the right hand side of a form? The problem is that there doesn't seem to be a way to get the width of the Popup menu before you call Popup(X, Y: Integer).

I'm trying to get a behavior similar to that of the system menu in Chrome.

解决方案

You could also just set Alignment to paRight and call

with ClientToScreen(Point(ClientWidth - 1, 0)) do
  Popup(X, Y);
