C＃区分拖放和鼠标单击 [英] C# distinguish Drag drop and Mouse click

问题描述

我有一个允许放置的表单，并且还需要捕获click事件。

I have a form which allows drop and also I need to capture the click event.

这里最棘手的部分是用户将对象拖放到 MouseClickEvent 也会被触发，因为他还单击了鼠标以释放该放置。

The tricky part here, is when the user drags and drop the object on the form, the MouseClickEvent also fired-because he also clicked the mouse to release the drop.

我该怎么办

预先感谢！

这是简短的还有更多的逻辑问题，所以我没有看到在这里放置代码的真正原因。

This is a short and more logic question so i didn't see a real reason to put pieces of code here..

谢谢！

推荐答案

添加一个全局布尔值，例如：

Add a global boolean, for instance:

private bool isDragAndDrop;

在加载表单时将其设置为false。触发dragAndDrop事件时，应设置 isDragAndDrop = true 。

Set it to false when loading the form. When the dragAndDrop event is fired you should set isDragAndDrop = true.

触发Click事件时，您检查 if（！isDragAndDrop）这将执行或不执行内部代码

When the Click event is fired you check if(!isDragAndDrop) This will or will not execute the code inside the click event based on the value on the isDragAndDrop -variable.

在离开点击事件之前，您设置的 isDragAndDrop = false

Before leaving the click event you the set isDragAndDrop = false
