WPF跟踪buttondown事件的最佳方法 [英] WPF best way to track buttondown event

问题描述

我需要每500毫秒增加一次我的属性值如果按钮被按下/按下.

这是示例代码片段

XAML

Hi I need to increase my property value every 500ms IF button is pressed/down.

Here is example code snippet

XAML

<Button Height="50" Width="100" Content="PressMe" MouseDown="Button_MouseDown"></Button>

private void Button_MouseDown(object sender, MouseButtonEventArgs e)
       {
           Value = Value + 1;
           System.Threading.Thread.Sleep(500);
       }

问题是我的事件永远不会触发.如果我在xaml中创建mouseClick事件，则会触发它，但不符合我的需求.

希望你有我的主意:)

干杯！

The problem is that my event never fires up. If I create mouseClick event in xaml it fires up, but doest fit my needs.

Hope you got my idea :)

Cheers!

推荐答案

您可能需要在ButtonDown事件上创建一个线程，并在ButtonUp事件上中止该线程.

线程将坐/旋转直到中止，然后每1/2秒(或您指定的间隔)增加目标值.

如果是我，我会使用BackgroundWorker对象作为我的线程处理，因为它很容易从对象外部取消.

You probably need to create a thread on the ButtonDown event, and abort that thread on the ButtonUp event.

The thread will sit/spin until aborted, and every 1/2 second (or the interval you specify), the target value is increased.

If it were me, I''d use a BackgroundWorker object as my thread processing because it''s easily cancellable from outside the object.
