提出两项WPF窗口一次？ [英] Move two WPF windows at once?

问题描述

我的主要窗口催生多数民众赞成位于顶部，看起来像的主要组成部分的子窗口。我想与主要移动子窗口同步，但我不知道怎么样。

My main window has spawned a child window that's positioned on top to look like part of the main. I would like to move the child window in sync with the main but I'm not sure how.

我的主窗口中有哪些事件MouseLeftButtonDown调用该函数我自己的标题栏：

My main window has my own title bar which event MouseLeftButtonDown calls this function:

public void DragWindow(object sender, MouseButtonEventArgs args)
{
     DragMove();
     UpdateChildWindowPosition();
}

这导致DragMove（）执行主窗口移到主窗口单独作为我拖动标题栏。不执行UpdateChildWindowPosition（），直到我释放，在它读取一些元素的坐标，并设置子窗口位置鼠标 - 你看到子窗口捕捉到这是不希望的位置

This results in DragMove() executing on the main window moves the main window alone as I drag the title bar. UpdateChildWindowPosition() is not executed until I release the mouse at which it reads some element coordinates and sets the child window position - you see the child window snap to the location which is not desired.

我怎么能有子窗口移动同步的主窗口？

How can I have the child window move in sync with the main window?

推荐答案

啊哈！

我的主要窗口有LocationChanged一个事件，我已经绑在我的UpdateChildWindowPosition（）。当LocationChange火灾（杜）的位置变化，所以它连续射击，我移动窗口时DragMove（）被我DragWindow上面贴执行。

My Main window has an event LocationChanged which I've tied to my UpdateChildWindowPosition(). LocationChange fires when (duh) the location changes so it's continuously firing as I move the window when DragMove() is being executed in my DragWindow posted above.
