改变WPF，有时作品光标，有时不 [英] Changing the cursor in WPF sometimes works, sometimes doesn't

问题描述

在我的几个用户控件，我用改变光标

On several of my usercontrols, I change the cursor by using

this.Cursor = Cursors.Wait;

当我点击的东西。

when I click on something.

现在我想要做同样的事情在WPF页面上点击一个按钮。当我将鼠标悬停在我的按钮，光标变成一只手，但是当我点击它，它不会更改为等待光标。我不知道这事做的事实，这是一个按钮，或者因为这是一个网页，而不是一个用户控件？这似乎是不可思议的行为。

Now I want to do the same thing on a WPF page on a button click. When I hover over my button, the cursor changes to a hand, but when I click it, it doesn't change to the wait cursor. I wonder if this has something to do with the fact that it's a button, or because this is a page and not a usercontrol? This seems like weird behavior.

推荐答案

你需要光标是一个等待的光标，只有当它已经结束了对特定页面/用户控件？如果没有，我建议使用<一个href=\"http://msdn.microsoft.com/en-us/library/system.windows.input.mouse.overridecursor.aspx\">Mouse.OverrideCursor:

Do you need the cursor to be a "wait" cursor only when it's over that particular page/usercontrol? If not, I'd suggest using Mouse.OverrideCursor:

Mouse.OverrideCursor = Cursors.Wait;
try
{
    // do stuff
}
finally
{
    Mouse.OverrideCursor = null;
}

这将覆盖光标为您的应用程序，而不是只为它的用户界面的一部分，因此，您所描述的问题消失。

This overrides the cursor for your application rather than just for a part of its UI, so the problem you're describing goes away.
